Creating a topic via the API using Node.js

개발

I am trying to create a new topic via Node.js API by sending the following payload :

 { title: 'topic:329201',
  raw: 'topic-description:32920111948',
  created_at: '2019-05-08',
  api_key:
   '2371b6549b0c3aeb1f12e49c22db5f25fb1f8ca740619e5304f12f4d29896097',
  api_username: 'cb1' 
}

I am hitting the API via HTTP module of node with the following options :

{ host: '13.127.14.24',
  port: '3000',
  path: '/posts',
  method: 'POST',
  headers:
   { 'content-type': 'application/x-www-form-urlencoded',
     'content-length': 194,
     Accept: '*/*',
     Connection: 'keep-alive' }
 }

But I am getting [“BAD CSRF”] in body. Can anyone help.

You should probably revoke that API key since you just posted it :wink:

This is usually because incorrect content-type encoding was specified in the request.

4

Don’t worry dude. I am smart enough to randomly change some characters in it.
And can you specify what i should send in ‘content-type’, as I’ve tried a lot of things.

5

Its neither working with Content-Type:application/x-www-form-urlencoded nor with ‘content-type’:‘application/json’.

You will tend to get “BAD CSRF” if your api key has not been supplied correctly. The best way to send it is via HTTP headers. There are more details at the top of our api documentation.

10

You might need to have correct capitalization for your header keys. So ‘content-type’ needs to be changed to ‘Content-Type’. Same for ‘Content-Length’, but you probably don’t even need to specify that one.

11

Fwiw: HTTP header names are (should be) case insensitive per RFC2616 4.2.

Problem solved. Thanks to @david. I was sending api_key in the payload but needed to send it via HTTP headers. I owe you a Beer. :laughing:

13

Ohh good, glad you got it working! Yes, sending them in the HTTP headers is the correct way to do it now, but they should still work in the body of the POST. Because I’m trying to improve our error messaging when using the API is there anything you changed as well? Also would you be willing to share the actual node http request code? And how are you using something like querystring.stringify on your payload? Thanks!

Vishal, would you mind sharing the Node code you’re using to make this request?

I’m stuck with a 404 error, no matter what I try.

@souljacker Sorry for the late reply. Were you able to get it working?

Blake, 엔지니어링 팀에서 Node.js로 동일한 요청을 보내는 방법에 대해 나에게도 안내해 줄 사람이 있을까요? 이 Python 스레드에 공개적으로 올리고 싶지 않다면 DM으로 이야기할 수 있어요. 정말 감사합니다!

node.js 웹사이트에 있는 예제를 수정하여 node.js를 사용하여 discourse에 POST 요청을 보내는 방법을 시연합니다:

const http = require('http');
const crypto = require('crypto');
const querystring = require('querystring');

const title = crypto.randomBytes(6).toString("hex") + ' ' + crypto.randomBytes(3).toString("hex") + ' ' + crypto.randomBytes(4).toString("hex");
const raw = crypto.randomBytes(16).toString("hex") + ' ' + crypto.randomBytes(16).toString("hex") + ' ' + crypto.randomBytes(16).toString("hex");

const api_key = 'f2b43adc...';
const api_username = 'system';

var data = {
  title: title,
  raw: raw
};

data = JSON.stringify(data);

const options = {
  hostname: 'localhost',
  port: 3000,
  path: '/posts',
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Content-Length': data.length,
    'Api-Key': api_key,
    'Api-Username': api_username
  }
};

const req = http.request(options, (res) => {
  console.log(`statusCode: ${res.statusCode}`)

  res.on('data', (d) => {
    process.stdout.write(d)
  })
});

req.on('error', (error) => {
  console.error(error)
});

req.write(data);
req.end();
