在NodeJS中发送POST请求时如何设置Content-Length? [英] How to set Content-Length when sending POST request in NodeJS?

问题描述

var https = require('https');  

var p = '/api/username/FA/AA?ZOHO_ACTION=EXPORT&ZOHO_OUTPUT_FORMAT=JSON&ZOHO_ERROR_FORMAT=JSON&ZOHO_API_KEY=dummy1234&ticket=dummy9876&ZOHO_API_VERSION=1.0';  

var https = require('https');  
var options = {  
  host: 'reportsapi.zoho.com',  
  port: 443,  
  path: p,  
  method: 'POST'  
};  

var req = https.request(options, function(res) {  
  console.log("statusCode: ", res.statusCode);  
  console.log("headers: ", res.headers);  
  res.on('data', function(d) {  
    process.stdout.write(d);  
  });  
});  
req.end();  

req.on('error', function(e) {  
  console.error(e);  
});  

当我运行上面的代码时，出现以下错误.

When i run the above code i am getting below error.

错误信息:

statusCode:  411  
headers:  { 'content-type': 'text/html',  
  'content-length': '357',  
  connection: 'close',  
  date: 'Thu, 24 Nov 2011 19:58:51 GMT',  
  server: 'ZGS',  
  'strict-transport-security': 'max-age=604800' }  
         "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">  


411 - Length Required  

如何修复 abobe 错误?
我试过在下面做

How to fix the abobe error?
I have tried doing below

var qs =   'ZOHO_ACTION=EXPORT&ZOHO_OUTPUT_FORMAT=JSON&ZOHO_ERROR_FORMAT=JSON&ZOHO_API_KEY=dummy1234&ticket=dummy9876&ZOHO_API_VERSION=1.0';
'   
options.headers = {'Content-Length': qs.length}  

但是，如果我尝试这种方式，则会出现以下错误:

But if I try this way I am getting below error:

{ stack: [Getter/Setter],  
  arguments: undefined,  
  type: undefined,  
  message: 'socket hang up' }  

有人可以帮我吗?

谢谢

PS:如果我在浏览器地址栏中输入整个 url 并按回车键，我将按预期获得 JSON 响应.

PS:If I enter the whole url into browser address bar and hit enter I am getting JSON response as expected.

推荐答案

事实证明，当您确实想要发出 POST 请求时，给定问题的解决方案显然是设置选项对象的headers"字段包含一个Content-Length"字段.

It turns out that the solution to the given problem, when you do want to make a POST request, is apparently to set the "headers" field of the options object to contain a 'Content-Length' field.
