Criando um tópico via API usando Node.js

Dev

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, você se importaria de compartilhar o código Node que está usando para fazer essa solicitação?

Estou travado com um erro 404, não importa o que eu tente.

19

@souljacker Desculpe pela resposta tardia. Você conseguiu fazer funcionar?

20

Blake, você tem alguém na sua equipe de engenharia que também possa me orientar sobre como fazer a mesma solicitação com Node.js? Podemos conversar via DM se você não quiser postar isso neste tópico de Python. Muito obrigado!

Adaptei o exemplo do site do node.js para demonstrar como enviar uma requisição POST para o Discourse usando node.js:

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();
