Node.JS：如何使用请求模块发送带有表单数据的标头

Node.JS: How to send headers with form data using request module

提问by Mykola G.

I have code like the following:

我有如下代码：

var req = require('request');

req.post('someUrl',
   { form: { username: 'user', password: '', opaque: 'someValue', logintype: '1'}, },
   function (e, r, body) {
      console.log(body);
});

How can I set headers for this? I need user-agent, content-type and probably something else to be in the headers:

如何为此设置标题？我需要用户代理、内容类型以及标题中的其他内容：

headers = { 
   'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.110 Safari/537.36',
   'Content-Type' : 'application/x-www-form-urlencoded' 
};

I've tried in multiple ways but I can either send header or form-data, failed to send both.

我尝试了多种方式，但我可以发送标题或表单数据，但无法同时发送。

I've finally managed to do it. Answer in code snippet below:

我终于设法做到了。在下面的代码片段中回答：

var querystring = require('querystring');
var request = require('request');

var form = {
    username: 'usr',
    password: 'pwd',
    opaque: 'opaque',
    logintype: '1'
};

var formData = querystring.stringify(form);
var contentLength = formData.length;

request({
    headers: {
      'Content-Length': contentLength,
      'Content-Type': 'application/x-www-form-urlencoded'
    },
    uri: 'http://myUrl',
    body: formData,
    method: 'POST'
  }, function (err, res, body) {
    //it works!
  });

This should work.

这应该有效。

var url = 'http://<your_url_here>';
var headers = { 
    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:24.0) Gecko/20100101 Firefox/24.0',
    'Content-Type' : 'application/x-www-form-urlencoded' 
};
var form = { username: 'user', password: '', opaque: 'someValue', logintype: '1'};

request.post({ url: url, form: form, headers: headers }, function (e, r, body) {
    // your callback body
});

I think it's just because you have forgot HTTP METHOD. The default HTTP method of request is GET.

我认为这只是因为您忘记了HTTP METHOD。请求的默认 HTTP 方法是 GET。

You should add method: 'POST'and your code will work if your backend receive the post method.

method: 'POST'如果您的后端收到 post 方法，您应该添加并且您的代码将起作用。

var req = require('request');

req.post({
   url: 'someUrl',
   form: { username: 'user', password: '', opaque: 'someValue', logintype: '1'},
   headers: { 
      'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.110 Safari/537.36',
      'Content-Type' : 'application/x-www-form-urlencoded' 
   },
   method: 'POST'
  },

  function (e, r, body) {
      console.log(body);
  });

    res.send(bodyValues);
});

Just remember set method to POST in options. Here is my code

只需记住在选项中将方法设置为 POST。这是我的代码

var options = {
    url: 'http://www.example.com',
    method: 'POST', // Don't forget this line
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'X-MicrosoftAjax': 'Delta=true', // blah, blah, blah...
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Safari/537.36',
    },
    form: {
        'key-1':'value-1',
        'key-2':'value-2',
        ...
    }
};

//console.log('options:', options);

// Create request to get data
request(options, (err, response, body) => {
    if (err) {
        //console.log(err);
    } else {
        console.log('body:', body);
    }
});
