I have the following API response named "body" and trying to log a specific field/submap, for example the "response" map. I don't really know the correct syntax in NodeJS or JavaScript.
{"get":"fixtures","parameters":{"league":"135","season":"2022","status":"NS","timezone":"Europe\/rome"},"errors":[],"results":40,"paging":{"current":1,"total":1},"response":[{"fixture":{"id":881790,"referee":"M. Piccinini","timezone":"Europe\/rome","date":"2022-08-20T18:30:00+02:00","timestamp":1661013000,"periods":{"first":null,"second":null},"venue":{"id":943,"name":"Stadio Olimpico Grande Torino","city":"Torino"},"status":{"long":"Not Started","short":"NS","elapsed":null}},"league":{"id":135,"name":"Serie A","country":"Italy","logo":"https:\/\/media.api-sports.io\/football\/leagues\/135.png","flag":"https:\/\/media.api-sports.io\/flags\/it.svg","season":2022,"round":"Regular Season - 2"},"teams":{"home":{"id":503,"name":"Torino","logo":"https:\/\/media.api-sports.io\/football\/teams\/503.png","winner":null},"away":{"id":487,"name":"Lazio","logo":"https:\/\/media.api-sports.io\/football\/teams\/487.png","winner":null}},"goals":{"home":null,"away":null},"score":{"halftime":{"home":null,"away":null},"fulltime":{"home":null,"away":null},"extratime":{"home":null,"away":null},"penalty":{"home":null,"away":null}}},]}
The code is below:
var request = require("request");
var options = {
method: 'GET',
url: 'https://v3.football.api-sports.io/fixtures?league=135&season=2022&status=NS&timezone=Europe/rome',
qs: {},
headers: {
'x-rapidapi-host': 'v3.football.api-sports.io',
'x-rapidapi-key': 'xxxxxxxxxxxxxxxxx'
}
};
request(options, function (error, response, body) {
if (error) throw new Error(error);
console.log(body);
});
I tried console.log(body.response); without success. I also tried body["response"] ending with "undefined" result.
It seems body was a String result so I could select the field with JSON syntax. I solved with console.log(JSON.parse(body).response[0]);
Two approaches:
Approach 1: Set the Content-Type as application/json in the server.
Approach 2: Convert the body from string to JSON object by JSON.parse

I am using request to get an image:
request(req.body.imageUrl, {encoding: null}, function(error, response, body) {
I then want to use the body to pass to an api that uses a multipart form and send that image (which is now in the body). I don't want to write the file to disk and then readstream from the disk again. I basically want to enter the formData of the next request by using the Buffer of the body, but it is not working.
So, for the options in the next request I have:
const options = {
method: "POST",
url: coreURL,
headers: {
"Content-Type": "multipart/form-data"
},
formData : {
file : new Buffer.from(body,'binary')
}
};
And this does not work, if I write the body to a file fs.writeFileSync(fileName, body, 'binary');
And then read in the options formData : { file : fs.createReadStream(fileName)}
it works but I cannot use the disk, so need an alternative way to pass the body into the next post as multipart form data.
Any ideas?
POC:
let request = require('request');
request.post({
url: "http://httpbin.org/anything",
formData: {
myfile: request.get("https://www.gravatar.com/avatar/f056d36f9e273fd4740ec8a5cea1348a"),
}
},
function (err, req, body) {
console.log(body);
}
);
I want to send a POST request (for example, with the 'request' module), but I don't find a way of sending unparsed data*.
*unparsed data => copied directly from the Chrome dev tool. Something like: tipo_accion=3&filtro=descarga&fecha=actual
It would also do the trick some way of translating that string to JSON.
I've tried so far with...
var request = require('request');
request.post({ url: 'https://target.com/form/', form: 'tipo_accion=3&filtro=descarga&fecha=actual' },
function (error, response, body) {
console.log(body)
}
);
... but it didn't work.
Firstly you should understand the difference between the request methods post and get.
The structure that you want to send:
tipo_accion=3&filtro=descarga&fecha=actual is telling me that you want to use a get request. So the proper code for that will be something like:
request(
'https://target.com/form/&tipo_accion=3&filtro=descarga&fecha=actual',
function (error, response, body) {
console.log(body)
},
);
But if it is a post request then you should use the json format
request.post({
url: 'https://target.com/form/', form: {
tipo_accion: 3,
filtro: 'descarga',
fecha: 'actual'
},
function(error, response, body) {
console.log(body)
}
);
You can convert form_data to string format and it works for me you can try it :
const request = require('request-promise');
var j = request.jar()
var data_fom = `a=value_a&b=value_b&c=value_c`
request({
url:"https://target.com/form/",
jar:j,
method:"POST",
resolveWithFullResponse: true,
form:data_form
})
currently my code looks like this. The problem is, it is serving me HTML instead of JSON. Am I querying the wrong location? Should I be using a package more sensible for handling this type of data? I just don't understand. Could anyone point me in the right direction? Thanks
var request = require('request');
var options = {
url: 'https://api.psychonautwiki.org/?query={ substances { name effects { name } }}',
headers: {
'Content-Type': 'application/json'
}
};
function callback(error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body);
}
}
request(options,callback);
}
GraphQL apis generally get query and the rest of your options in as the request body, and mostly use the POST http method. It seems like this api reacts to your GET request with a GraphiQL user interface, that's why you are getting html as response.
Try adding an Accept header to tell the server what you're expecting back.
'Accept': 'application/json'
I'm using request module on node.js but there is something problem with encoding option. beneath codes are simple post request, but I don't know how to set up encoding of form field data. I already set headers to 'Content-Type': 'application/x-www-form-urlencoded; charset=euc-kr' But it doesn't works. field data is korean, like "안녕하세요", and I should post it with euc-kr encoding. (The site takes euc-kr, not utf8)
The same program on Java application, I coded like this :
PrintWriter wr = new PrintWriter(new OutputStreamWriter(conn.getOutputStream(), "euc-kr"));
But I don't know how to in nodejs. Can anyone give some solution...?
Code Sample
//Load the request module
var request = require('request');
//Lets configure and request
request({
url: 'http://google.com', //URL to hit
headers: { 'Content-Type': 'application/x-www-form-urlencoded; charset=euc-kr' },
method: 'POST',
form: {
field1: 'data',
field2: 'data'
}
}, function(error, response, body){
if(error) {
console.log(error);
} else {
console.log(response.statusCode, body);
}
});
Finally I got a soultion, and I solved this problem.
If you send a data as a form using request module, the module change your form encoding to utf-8 by force. So even you setted your form encoding to another charset, the module changes your charset to utf8 again. You can see that at request.js on line 1120-1130.
So, You'd better send a data by 'body' option, not 'form' option.
Node doesn't support EUC-KR so you can use iconv-lite to extend the native encodings available and set the encoding option in request.
List of Natively Supported Encodings
iconv.extendNodeEncodings(); only works for node pre v4+. See here to get this working for a newer version of node.
var iconv = require('iconv-lite');
var request = require('request');
// This will add to the native encodings available.
iconv.extendNodeEncodings();
request({
url: 'http://google.com', //URL to hit
method: 'POST',
form: {
field1: 'data',
field2: 'data'
},
encoding: 'EUC-KR'
}, function(error, response, body){
if(error) {
console.log(error);
} else {
console.log(response.statusCode, body);
}
});
iconv.undoExtendNodeEncodings();
I send it like so :
var url = "http://localhost:9001/v1/sanger/auth/facebook/callback",
options = {body: JSON.stringify(params), 'Content-type': 'application/json'};
request.post(url, options, function (error, response, body) {
... callbacks ...
});
I am not getting the params in the route (tried body, params and query)
When I use postman (http://cl.ly/image/473e2m173M2v) I get it in the req.body
A better way to do this (I'm assuming you've initialized your params variable somewhere else):
request = require('request');
var options = {
url: "http://localhost:9001/v1/sanger/auth/facebook/callback",
method: 'POST',
body: params,
json: true
};
request(options, function (error, response, body) {
... callbacks ...
});
You're not able to get the body because when you call JSON.stringify(params), you're converting params to a string and you don't have a json object anymore. If you send the information as plain/text but tell the request that you want json, your express app cannot verify the content-type, as could check with:
request.get('Content-Type'); // returns undefined
Since you want a json object, you shouldn't do this. Just pass the json object, like in the example above.
Then, in your route code, you can do both req.body or req.param('a_param') (for a especific key of your json) to get those values.
