javascript - Node.js http - 将 GET 数据发送到服务器

Question

如何使用 https/http 模块通过 GET 方法发送数据？使用 POST 一切正常。

第一个代码 (GET):

var querystring = require('querystring'),
    protocol = require('https');

var options = {
  host: 'httpbin.org',
  path: 'get',
  method: 'GET',
  headers: {},
  port: 443
};

var data = querystring.stringify({
  limit: 3
});

Object.assign(options.headers, {
  'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
  'Content-Length': Buffer.byteLength(data)
});

var req = protocol.request(options, response => {
  response.setEncoding('utf8');
  var end = '';
  response.on('data', data => end += data);
  response.on('end', () => console.log(end));
});
req.write(data);
req.end();

回应:

{
  "args": {},
  "headers": {
    "Connection": "close",
    "Content-Length": "7",
    "Content-Type": "application/x-www-form-urlencoded; charset=UTF-8",
    "Host": "httpbin.org"
  },
  "origin": "31.0.120.218",
  "url": "https://httpbin.org/get"
}

第二个代码(POST，我只替换了选项对象):

var options = {
  host: 'httpbin.org',
  path: 'post',
  method: 'POST',
  headers: {},
  port: 443
};

回应:

{
  "args": {},
  "data": "",
  "files": {},
  "form": {
    "limit": "3"
  },
  "headers": {
    "Connection": "close",
    "Content-Length": "7",
    "Content-Type": "application/x-www-form-urlencoded; charset=UTF-8",
    "Host": "httpbin.org"
  },
  "json": null,
  "origin": "31.0.120.218",
  "url": "https://httpbin.org/post"
}

我将非常感谢您的帮助，现在我不知道我做错了什么。

您的问题是，在 get 中，查询被附加到路径中，正如 @Quy 指出的那样，get 请求没有正文。如果不了解服务器是如何设置的，我会考虑这样做:

var data = querystring.stringify({
  limit: 3
});

var options = {
  host: 'httpbin.org',
  path: 'get?' + data,
  method: 'GET',
  headers: {},
  port: 443
};
