我如何用Node.js的HTTP客戶端發表文章？

Question

我想在這裏按照文檔

http://nodejs.org/api/http.html

但我不能找到做一些簡單的，如張貼到URL的用戶名和密碼的文檔。我將如何做到這一點？

Answer 1

如果你需要做的不僅僅是一個POST更多的事情，比如消費一個RESTful API，我建議你看一看restler。

它有一個非常簡單的API

var rest = require('restler'); 

rest.post('http://service.com/login', { 
    data: { username: 'foo', password: 'bar' }, 
}).on('complete', function(data, response) { 
    if (response.statusCode == 200) { 
    // you can get at the raw response like this... 
    } 
}); 

Answer 2

Node.js的文檔不會在這個

http://nodejs.org/api/http.html#http_http_request_options_callback

這是我會怎麼做請求，使用查詢字符串來特別清楚解析輸入。

//require a few things. 

var http = require('http'), 
    qs = require('qs'); 

//These are the post options 
var options = { 
    hostname: 'www.mysite.com', 
    port: 80, 
    path: '/auth', 
    method: 'POST' 
}; 
//The postdata can be anything, but I'm using querystring 
//to convert it into the format 
//username=User&password=Password to be easily parsed in php 

var postdata = qs.stringify({ 
    username:"User", 
    password:"Password" 
}); 

//Initialise the variable that will store the response 
var body=''; 


//Now we're going to set up the request and the callbacks to handle the data 
var request = http.request(options, function(response) { 
    //When we receive data, we want to store it in a string 
    response.on('data', function (chunk) { 
     body += chunk; 
    }); 
    //On end of the request, run what we need to 
    response.on('end',function() { 
     //Do Something with the data 
     console.log(body); 
    }); 
}); 

//Now we need to set up the request itself. 
//This is a simple sample error function 
request.on('error', function(e) { 
    console.log('problem with request: ' + e.message); 
}); 


//Write our post data to the request 
request.write(postdata); 
//End the request. 
request.end();
