I'm new to programing and wanted to use the output from a child process as variable name, and this is how I failed:
var payload = outPutFromChildProcess;
{
var red = '{"sat": 254,"xy": [0.68,0.31]}';
var white = '{"ct":0}';
request({
method: 'PUT',
uri: 'http://192.168.2.17/api/*****',
json: JSON.stringify(payload)
}, (e, r, b) => {
if(e)return console.error("Bridge unreachable");
console.log(JSON.stringify(b[0].success));
});
}
I know it's very wrong on many level, and I'm deeply sorry for letting you read it.
But how do I make it work?
install axios: npm i axios
then:
const payload = { "sat": 254,"xy": [0.68,0.31] };
const config = { headers: {'Content-Type': 'application/json'} };
(async () => {
const res = await axios.put('http://192.168.2.17/api/*****', payload, config);
})();

I'm using NestJS, there is axios module inside it. I read that Telegram accepts only multipart/form-data for files, so I use form-data package. I have only 400 errors, that don't represent anything.
I don't want to use packages like telegraf (it's awesome, I know) for this simple usecase.
const config: AxiosRequestConfig = {
headers: { 'Content-Type': 'multipart/form-data' },
};
const file = await readFile(path);
const body = new FormData();
body.append('chat_id', this.chatId.toString());
body.append('document', file, { filename: 'document.pdf' });
try {
const res = await firstValueFrom(this.http.post(`${this.tgURL}/sendDocument`, body, config));
} catch (e) {
console.log(e.message);
}
Telegram needs boundary in header.
So:
const config: AxiosRequestConfig = {
headers: { 'Content-Type': `multipart/form-data; boundary=${body.getBoundary()}` },
};
i'm trying to upload my files as form-data, after i've created a scene. But I receive always the error "Specified Photoscene ID doesn't exist in the database" (which were created directly before).
My upload function:
// Upload Files
async function uploadFiles(access_Token, photoSceneId, files) {
try {
const params = new URLSearchParams({
'photosceneid': photoSceneId,
'type': 'image',
'file': files
})
const headers = Object.assign({
Authorization: 'Bearer ' + access_Token,
'Content-Type': 'multipart/form-data' },
files.getHeaders()
)
let resp = await axios({
method: 'POST',
url: 'https://developer.api.autodesk.com/photo-to-3d/v1/file',
headers: headers,
data: params
})
let data = resp.data;
return data;
} catch (e) {
console.log(e);
}
};
I've also tried a few varaints, e.g. adding the photosceneId to the form data (form.append(..), but doesn't works either.
Any helpful suggestion are appreciated. Thx in advance.
There might be two problems here.
First, I am not sure of it, as I don't have experience of URLSearchParams as a "packer" for POST requests. This might be the reason why you get "Specified Photoscene ID doesn't exist in the database" error - perhaps the way the data are serialized using URLSearchParams is not compatible.
The second problem, I am sure of it, is regarding the way you submit the files.
According to documentation, you have to pass the files one by one, like
"file[0]=http://www.autodesk.com/_MG_9026.jpg" \
"file[1]=http://www.autodesk.com/_MG_9027.jpg"
and not just passing an array to the "file" field.
Having this said, try this approach:
var axios = require('axios');
var FormData = require('form-data');
var fs = require('fs');
var data = new FormData();
var TOKEN = 'some TOKEN';
const photoSceneID = 'some_photoscene_id';
data.append('photosceneid', photoSceneID);
data.append('type', 'image');
data.append('file[0]', fs.createReadStream('/C:/TEMP/Example/DSC_5427.JPG'));
data.append('file[1]', fs.createReadStream('/C:/TEMP/Example/DSC_5428.JPG'));
data.append('file[2]', fs.createReadStream('... and so on ...'));
var config = {
method: 'post',
url: 'https://developer.api.autodesk.com/photo-to-3d/v1/file',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Authorization': 'Bearer ' + TOKEN,
},
data : data
};
axios(config)
.then(function (response) {
console.log(JSON.stringify(response.data));
})
.catch(function (error) {
console.log(error);
});
Also, I always recommend instead of jumping right into the code, to check first the workflow using apps like Postman or Insomnia and then, after you validated the workflow (created the photoscene, all images were properly uploaded and so on), you can translate this into the code.
At the end of this blogpost you will find the link to alrady created Postman collection, but I highly recommend building your own collection, as part of the learning step.
This is the solution that worked for me. Please note that the upload should be limited by a maximum of 20 files per call.
// Upload Files
async function uploadFiles(access_Token, photoSceneId) {
try {
let dataPath = path.join(__dirname, '../../data')
let files = fs.readdirSync(dataPath)
var data = new FormData();
data.append('photosceneid', photoSceneId)
data.append('type', 'image')
for(let i=0; i < files.length; i++) {
let filePath = path.join(dataPath, files[i])
let fileName = 'file[' + i + ']'
data.append(fileName, fs.createReadStream(filePath))
}
const headers = Object.assign({
Authorization: 'Bearer ' + access_Token,
'Content-Type': 'multipart/form-data;boundary=' + data.getBoundary()},
data.getHeaders()
)
let resp = await axios({
method: 'POST',
url: 'https://developer.api.autodesk.com/photo-to-3d/v1/file',
headers: headers,
maxContentLength: Infinity,
maxBodyLength: Infinity,
data: data
})
let dataResp = resp.data;
return dataResp;
} catch (e) {
console.log(e);
}
};

I am trying to upload an image to imgbb using their api using Axios, but keep getting an error response Empty upload source.
The API docs for imgbb shows the following example:
curl --location --request POST "https://api.imgbb.com/1/upload?key=YOUR_CLIENT_API_KEY" --form "image=R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7"
My node code to replicate this is:
const fs = require('fs')
const FormData = require('form-data')
const Axios = require('axios').default
let file = '/tmp/the-test.png'
let url = 'https://api.imgbb.com/1/upload?key=myapikey'
var bodyData = new FormData();
let b = fs.readFileSync(file, {encoding: 'base64'})
bodyData.append('image', b)
Axios({
method: 'post',
url: 'url',
headers: {'Content-Type': 'multipart/form-data' },
data: {
image: bodyData
}
}).then((resolve) => {
console.log(resolve.data);
}).catch(error => console.log(error.response.data));
But I keep getting the following error response..
{
status_code: 400,
error: { message: 'Empty upload source.', code: 130, context: 'Exception' },
status_txt: 'Bad Request'
}
Not sure exactly where I am failing.
For the sake of completion and for others, how does the --location flag translate to an axios request?
The issue was in the headers. When using form-data, you have to make sure to pass the headers generated by it to Axios. Answer was found here
headers: bodyData.getHeaders()
Working code is:
const fs = require('fs');
const FormData = require('form-data');
const Axios = require('axios').default;
let file = '/tmp/the-test.png';
var bodyData = new FormData();
let b = fs.readFileSync(file, { encoding: 'base64' });
bodyData.append('image', b);
Axios({
method : 'post',
url : 'https://api.imgbb.com/1/upload?key=myapikey',
headers : bodyData.getHeaders(),
data : bodyData
})
.then((resolve) => {
console.log(resolve.data);
})
.catch((error) => console.log(error.response.data));
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 using the stream-to-promise npm module to create the multipart/form-data payload in my jasmine test. My payload includes an image file as a buffer but when the payload is put through stream-to-promise it changes or corrupts my original image buffer in the payload somehow and so my tests are failing. Is there a way to prevent this?
it('test /identity-verification/your-first-form-of-id POST with validation passing', function(done){
var form = new FormData();
var image = fs.createReadStream("image.png");
streamToBuffer(image, function (err, buffer) {
form.append('firstID', 'passport');
form.append('firstIDImage', buffer);
var headers = form.getHeaders();
streamToPromise(form).then(function(payload) {
var options = {
method: 'POST',
url: '/identity-verification/your-first-form-of-id',
payload: payload,
headers: headers
};
server.inject(options, function(response) {
expect(response.statusCode).toBe(302);
expect(response.headers.location).toMatch('/identity-verification/your-first-form-of-id/upload-successful');
done();
});
});
});
});
The buffer in the payload after being put through stream-to-promise looks like this:
You don't need stream-to-buffer. You've already got the buffer from createReadStream. If you get rid of that, it should work. One thing to be careful of is that your maxBytes is set high enough to accomodate your test image. This was causing some cryptic errors when I was testing.
The code below is working fine for me.
var streamToPromise = require("stream-to-promise");
var FormData = require("form-data");
var fileTypeModule = require("file-type");
var fs = require("fs");
var q = require("q");
var Hapi = require('hapi');
var server = new Hapi.Server({ debug: { request: ['error'] } });
server.connection({
host: 'localhost',
port: 8000
});
server.route({
method: 'POST',
path: '/test',
handler: function(request, reply) {
var data = request.payload.firstIDImage;
var fileType = fileTypeModule(data);
reply(fileType);
},
config: {
payload: { maxBytes: 1048576 }
}
});
var start = server.start();
var form = new FormData();
var headers = form.getHeaders();
form.append('firstID', 'passport');
form.append('firstIDImage', fs.createReadStream("image.png"));
var append = streamToPromise(form);
q.all([start, append]).then((results) => {
var options = {
method: 'POST',
url: '/test',
payload: results[1],
headers: headers
};
server.inject(options, function(response) {
console.log(response.payload);
});
});
