I want to send a post request that contain a form data, i want to do that from nodejs to another external api, i don't have the front-end to send the formData, so all i have a javascript object that has keys and values, so how can i do that?, when i tried sending a normal object, i didn't get the right api response, but when i sent it with a POSTMAN client, i got the correct response.
If you have a correct result in Postman, it's interesting to use the code generator in the same tools to have the desired code :). The button "</>" is on the right bar of the screen.
Here is the code generated from the tool :
var axios = require('axios');
var FormData = require('form-data');
var data = new FormData();
data.append('data', 'asldkfjalsdkjf');
var config = {
method: 'post',
url: 'https://some-domain.com/formdata',
headers: {
...data.getHeaders()
},
data : data
};
axios(config)
.then(function (response) {
console.log(JSON.stringify(response.data));
})
.catch(function (error) {
console.log(error);
});
It's cool, isn't it?
One more thing, you have many options from NodeJS to C#, PHP.. :)
So you want to make a post request with nodejs? In order to do so, you can use the axios library and send the data in the following way.
const axios = require('axios');
let formData = new FormData();
formData.append('x': 'some test data');
axios({
method: 'post',
url: 'https://stackoverflow.com/posts/67709177',
data: formData,
headers: { 'Content-Type': 'multipart/form-data' },
})
.then(res => {
console.log(`statusCode: ${res.statusCode}`)
console.log(res)
})
.catch(error => {
console.error(error)
})
You can install axios using this command.
npm i axios

I'm trying to upload on image on the Prestashop API with form-data/axios.
For that, i just need to send a post request with the images joined in an "image" parameter.
I did this simple node.js script (mine is much more complicated but i simplified for here):
const FormData = require("form-data");
const fs = require("fs");
const axios = require("axios");
// Read the image file into a buffer
const imageBuffer = fs.readFileSync("image.jpg");
// Create a FormData object
const form = new FormData();
// Append the image buffer to the form data
form.append("image", imageBuffer);
// Make an HTTP POST request to the PrestaShop API
axios({
method: "POST",
url: "https://XXX/api/images/products/15924",
data: form, // set the request body using the data field
params: {
ws_key: "XXX",
},
headers: {
"Content-Type": "multipart/form-data; boundary=" + form.getBoundary(),
},
})
.then((response) => {
console.log(response);
})
.catch((error) => {
console.error(error.response.data);
});
But i get this answer:
<message><![CDATA[Please set an "image" parameter with image data for value]]></message>
I tried a LOT of things. With fs.createReadStream instead of formData, with http instead of axios, with a buffer or a file, etc ... and i alway end with this error.
I would be glad if someone has an idea :-)
Thx !
I finally succeed!
Two changed were needed:
Adding the filename in the append (thanks Dmitriy Mozgovoy for pointing that out in the comment)
Adding the size in the headers with "Content-Length": formData.getLengthSync()
Without these 2 missing elements, it seems that PHP received an empty $_FILES variable.
Final version:
const FormData = require("form-data");
const fs = require("fs");
const axios = require("axios");
// Read the image file into a buffer
const imageBuffer = fs.readFileSync("image.jpg");
// Create a FormData object
const form = new FormData();
// Append the image buffer to the form data
form.append("image", imageBuffer, "image.jpg");
// Make an HTTP POST request to the PrestaShop API
axios
.post("https://example.com/api/images/products/15924", form, {
params: {
ws_key: "EXAMPLE",
},
headers: {
...form.getHeaders(),
"Content-Length": form.getLengthSync(),
},
})
.then((response) => {
console.log(response);
})
.catch((error) => {
console.error(error.response.data);
});
This is what my "dev" sent me. Someone help please
I'm trying my best, but their API doesn't respond to our methods. This authentication is the root of the problem. I'm right now using Axios(the most popular and only method for making API requests for web apps) but it's not accepting request
and then i told him i would ask for help*
You can ask this question- ` How do I make requests for creating order API in my express app? I've tried to make the request by getting my form data from my EJS form using the request.body. But still, it is saying error 400.
Here is his code:
app.post('/order-labels', checkAuthenticated, (req, res) => {
const data = JSON.stringify(req.body);
console.log(data)
const config = {
method: 'post',
url: 'https://labelsupply.io/api/order',
headers: {
'X-Api-Auth': '32854090-03dd-a3c1-Deleted some for safety',
'Content-Type': 'application/x-www-form-urlencoded'
},
data: data
};
axios(config)
.then(function(response) {
console.log(response.data);
})
.catch(function(error) {
console.log(error);
});
})
by console.logging we are getting the data, but the API doesn't accepting
The API Docs are here.
you may need an account to view just put junk
The API calls for url encoded string.
const data = JSON.stringify(req.body);
console.log(data)
data = new URLSearchParams(Object.entries(data)).toString();
console.log(data); // now should be URL encoded
const config = {
method: 'post',
url: 'https://labelsupply.io/api/order',
headers: {
'X-Api-Auth': '32854090-03dd-a3c1-Deleted some for safety',
'Content-Type': 'application/x-www-form-urlencoded'
},
data: data
};
See if the API likes the new encoding?
So I have a URL that contains an image, and I want to pass that image as part of multipart form data to an API (to be specific, if it matters, the ClickUp API). I'm doing all of this inside of a Figma plugin, which is a browser environment.
The url looks something like https://s3-alpha-sig.figma.com....
The request works perfectly for a local image that I add manually, such as in Postman. Here is the code for a successful Postman request to this endpoint:
var axios = require('axios');
var FormData = require('form-data');
var fs = require('fs');
var data = new FormData();
data.append('attachment', fs.createReadStream('7UI7S5-pw/fdb54856-9c05-479f-b726-016ef252d9f5.png'));
data.append('filename', 'example.png');
var config = {
method: 'post',
url: 'https://api.clickup.com/api/v2/task/2phh5bf/attachment',
headers: {
'Authorization': '(my auth token)',
...data.getHeaders()
},
data : data
};
axios(config)
.then(function (response) {
console.log(JSON.stringify(response.data));
})
However, I don't have access to local files and need to upload from a URL, so here's what I've done so far:
var data = new FormData();
data.append('attachment', open(imgURL));
data.append('filename', 'screenshot.png');
fetch(`(the URL)`, {
"method": "POST",
"muteHttpExceptions": true,
"headers": {
'Authorization': '(my auth token)',
...data.headers
},
data: data
}).then(response => {
console.log(response)
})
How should I be converting the URL into something I can input as Form Data? Thanks so much in advance!
I have an API endpoint that lets the client post their csv to our server then post it to someone else server. I have done our server part which save uploaded file to our server, but I can't get the other part done. I keep getting error { message: 'File not found', code: 400 } which may mean the file never reach the server. I'm using axios as an agent, does anyone know how to get this done? Thanks.
// file = uploaded file
const form_data = new FormData();
form_data.append("file", fs.createReadStream(file.path));
const request_config = {
method: "post",
url: url,
headers: {
"Authorization": "Bearer " + access_token,
"Content-Type": "multipart/form-data"
},
data: form_data
};
return axios(request_config);
Update
As axios doc states as below and the API I'm trying to call requires a file
// data is the data to be sent as the request body
// Only applicable for request methods 'PUT', 'POST', and 'PATCH'
// When no transformRequest is set, must be of one of the following types:
// - string, plain object, ArrayBuffer, ArrayBufferView, URLSearchParams
// - Browser only: FormData, File, Blob
// - Node only: Stream, Buffer
Is there any way to make axios send a file as a whole? Thanks.
The 2 oldest answers did not work for me. This, however, did the trick:
const FormData = require('form-data'); // npm install --save form-data
const form = new FormData();
form.append('file', fs.createReadStream(file.path));
const request_config = {
headers: {
'Authorization': `Bearer ${access_token}`,
...form.getHeaders()
}
};
return axios.post(url, form, request_config);
form.getHeaders() returns an Object with the content-type as well as the boundary.
For example:
{ "content-type": "multipart/form-data; boundary=-------------------0123456789" }
I'm thinking the createReadStream is your issue because its async. try this.
Since createReadStream extends the event emitter, we can "listen" for when it finishes/ends.
var newFile = fs.createReadStream(file.path);
// personally I'd function out the inner body here and just call
// to the function and pass in the newFile
newFile.on('end', function() {
const form_data = new FormData();
form_data.append("file", newFile, "filename.ext");
const request_config = {
method: "post",
url: url,
headers: {
"Authorization": "Bearer " + access_token,
"Content-Type": "multipart/form-data"
},
data: form_data
};
return axios(request_config);
});
This is what you really need:
const form_data = new FormData();
form_data.append("file", fs.createReadStream(file.path));
const request_config = {
headers: {
"Authorization": "Bearer " + access_token,
"Content-Type": "multipart/form-data"
},
data: form_data
};
return axios
.post(url, form_data, request_config);
In my case, fs.createReadStream(file.path) did not work.
I had to use buffer instead.
const form = new FormData();
form.append('file', fs.readFileSync(filePath), fileName);
const config = {
headers: {
Authorization: `Bearer ${auth.access_token}`,
...form.getHeaders(),
},
};
axios.post(api, form.getBuffer(), config);
I have made an interceptor you can connect to axios to handle this case in node: axios-form-data. Any feedback would be welcome.
npm i axios-form-data
example:
import axiosFormData from 'axios-form-data';
import axios from 'axios';
// connect axiosFormData interceptor to axios
axios.interceptors.request.use(axiosFormData);
// send request with a file in it, it automatically becomes form-data
const response = await axios.request({
method: 'POST',
url: 'http://httpbin.org/post',
data: {
nonfile: 'Non-file value',
// if there is at least one streamable value, the interceptor wraps the data into FormData
file: createReadStream('somefile'),
},
});
// response should show "files" with file content, "form" with other values
// and multipart/form-data with random boundary as request header
console.log(response.data);
I had a same issue, I had a "pdf-creator-service" for generate PDF document from html.
I use mustache template engine for create HTML document - https://www.npmjs.com/package/mustache
Mustache.render function returns html as a string what do I need to do to pass it to the pdf-generator-service ? So lets see my suggestion bellow
//...
async function getPdfDoc(props: {foo: string, bar: string}): Promise<Buffer> {
const temlateFile = readFileSync(joinPath(process.cwd(), 'file.html'))
mustache.render(temlateFile, props)
const readableStream = this.getReadableStreamFromString(htmlString)
const formData = new FormData() // from 'form-data'
formData.append('file', options.file, { filename: options.fileName })
const formHeaders = formData.getHeaders()
return await axios.send<Buffer>(
{
method: 'POST',
url: 'https://pdf-generator-service-url/pdf',
data: formData,
headers: {
...formHeaders,
},
responseType: 'arraybuffer', // ! important
},
)
}
getReadableStreamFromString(str: string): Readable {
const bufferHtmlString = Buffer.from(str)
const readableStream = new Readable() // from 'stream'
readableStream._read = () => null // workaround error
readableStream.push(bufferHtmlString)
readableStream.push(null) // mark end of stream
return readableStream
}
For anyone who wants to upload files from their local filesystem (actually from anywhere with the right streams architecture) with axios and doesn't want to use any external packages (like form-data).
Just create a readable stream and plug it right into axios request function like so:
await axios.put(
url,
fs.createReadStream(path_to_file)
)
Axios accepts data argument of type Stream in node context.
Works fine for me at least in Node v.16.13.1 and with axios v.0.27.2
I'm switching one of my projects from request over to something a bit more light-weight (such as got, axios, or fetch). Everything is going smoothly, however, I'm having an issue when attempting to upload a file stream (PUT and POST). It works fine with the request package, but any of the other three return a 500 from the server.
I know that a 500 generally means an issue on the server's end, but it is consistent only with the HTTP packages that I'm testing out. When I revert my code to use request, it works fine.
Here is my current Request code:
Request.put(`http://endpoint.com`, {
headers: {
Authorization: `Bearer ${account.token.access_token}`
},
formData: {
content: fs.createReadStream(localPath)
}
}, (err, response, body) => {
if (err) {
return callback(err);
}
return callback(null, body);
});
And here is one of the attempts using another package (in this case, got):
got.put(`http://endpoint.com`, {
headers: {
'Content-Type': 'multipart/form-data',
Authorization: `Bearer ${account.token.access_token}`,
},
body: {
content: fs.createReadStream(localPath)
}
})
.then(response => {
return callback(null, response.body);
})
.catch(err => {
return callback(err);
});
Per the got documentation, I've also tried using the form-data package in conjunction with it according to its example and I still get the same issue.
The only difference between these 2 I can gather is with got I do have to manually specify the Content-Type header otherwise the endpoint does give me a proper error on that. Otherwise, I'm not sure how the 2 packages are constructing the body with the stream, but as I said, fetch and axios are also producing the exact same error as got.
If you want any of the snippets using fetch or axios I'd be happy to post them as well.
I know this question was asked a while ago, but I too am missing the simple pipe support from the request package
const request = require('request');
request
.get("https://res.cloudinary.com/demo/image/upload/sample.jpg")
.pipe(request.post("http://127.0.0.1:8000/api/upload/stream"))
// Or any readable stream
fs.createReadStream('/Users/file/path/localFile.jpeg')
.pipe(request.post("http://127.0.0.1:8000/api/upload/stream"))
and had to do some experimenting to find similar features from current libraries.
Unfortunately, I haven't worked with "got" but I hope the following 2 examples help someone else that are interested in working with the Native http/https libraries or the popular axios library
HTTP/HTTPS
Supports piping!
const http = require('http');
const https = require('https');
console.log("[i] Test pass-through: http/https");
// Note: http/https must match URL protocol
https.get(
"https://res.cloudinary.com/demo/image/upload/sample.jpg",
(imageStream) => {
console.log(" [i] Received stream");
imageStream.pipe(
http.request("http://localhost:8000/api/upload/stream/", {
method: "POST",
headers: {
"Content-Type": imageStream.headers["content-type"],
},
})
);
}
);
// Or any readable stream
fs.createReadStream('/Users/file/path/localFile.jpeg')
.pipe(
http.request("http://localhost:8000/api/upload/stream/", {
method: "POST",
headers: {
"Content-Type": imageStream.headers["content-type"],
},
})
)
Axios
Note the usage of imageStream.data and that it's being attached to data in the Axios config.
const axios = require('axios');
(async function selfInvokingFunction() {
console.log("[i] Test pass-through: axios");
const imageStream = await axios.get(
"https://res.cloudinary.com/demo/image/upload/sample.jpg",
{
responseType: "stream", // Important to ensure axios provides stream
}
);
console.log(" [i] Received stream");
const upload = await axios({
method: "post",
url: "http://127.0.0.1:8000/api/upload/stream/",
data: imageStream.data,
headers: {
"Content-Type": imageStream.headers["content-type"],
},
});
console.log("Upload response", upload.data);
})();
Looks like this was a headers issue. If I use the headers directly from FormData (i.e., headers: form.getHeaders()) and just add in my additional headers afterwards (Authorization), then this ends up working just fine.
For me just works when I added other parameters on FormData.
before
const form = new FormData();
form.append('file', fileStream);
after
const form = new FormData();
form.append('file', fileStream, 'my-whatever-file-name.mp4');
So that way I can send stream from my backend to another backend in node, waiting a file in multipart/form-data called 'file'
