如果有基本授权，如何在Node.js中使用http.client

根据标题，我该怎么做？

这是我的代码：

var http = require('http');

// to access this url I need to put basic auth.
var client = http.createClient(80, 'www.example.com');

var request = client.request('GET', '/', {
    'host': 'www.example.com'
});
request.end();
request.on('response', function (response) {
  console.log('STATUS: ' + response.statusCode);
  console.log('HEADERS: ' + JSON.stringify(response.headers));
  response.setEncoding('utf8');
  response.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
});

您必须Authorization在标题中设置该字段。

Basic在这种情况下，它包含身份验证类型以及username:password在Base64中编码的组合：

var username = 'Test';
var password = '123';
var auth = 'Basic ' + Buffer.from(username + ':' + password).toString('base64');
// new Buffer() is deprecated from v6

// auth is: 'Basic VGVzdDoxMjM='

var header = {'Host': 'www.example.com', 'Authorization': auth};
var request = client.request('GET', '/', header);

从Node.js http.request API文档中， 您可以使用类似于

var http = require('http');

var request = http.request({'hostname': 'www.example.com',
                            'auth': 'user:password'
                           }, 
                           function (response) {
                             console.log('STATUS: ' + response.statusCode);
                             console.log('HEADERS: ' + JSON.stringify(response.headers));
                             response.setEncoding('utf8');
                             response.on('data', function (chunk) {
                               console.log('BODY: ' + chunk);
                             });
                           });
request.end();

var username = "Ali";
var password = "123";
var auth = "Basic " + new Buffer(username + ":" + password).toString("base64");
var request = require('request');
var url = "http://localhost:5647/contact/session/";

request.get( {
    url : url,
    headers : {
        "Authorization" : auth
    }
  }, function(error, response, body) {
      console.log('body : ', body);
  } );

一个更简单的解决方案是直接在URL中使用user：pass @ host格式。

使用请求库：

var request = require('request'),
    username = "john",
    password = "1234",
    url = "http://" + username + ":" + password + "@www.example.com";

request(
    {
        url : url
    },
    function (error, response, body) {
        // Do more stuff with 'body' here
    }
);

我也为此写了一个小博客。

对于我在OSX上使用node.js 0.6.7的价值，我无法使用“ Authorization”：auth来与我们的代理一起使用，需要将其设置为“ Proxy-Authorization”：auth我的测试代码是：

var http = require("http");
var auth = 'Basic ' + new Buffer("username:password").toString('base64');
var options = {
    host: 'proxyserver',
    port: 80,
    method:"GET",
    path: 'http://www.google.com',
    headers:{
        "Proxy-Authorization": auth,
        Host: "www.google.com"
    } 
};
http.get(options, function(res) {
    console.log(res);
    res.pipe(process.stdout);
});

var http = require("http");
var url = "http://api.example.com/api/v1/?param1=1&param2=2";

var options = {
    host: "http://api.example.com",
    port: 80,
    method: "GET",
    path: url,//I don't know for some reason i have to use full url as a path
    auth: username + ':' + password
};

http.get(options, function(rs) {
    var result = "";
    rs.on('data', function(data) {
        result += data;
    });
    rs.on('end', function() {
        console.log(result);
    });
});

我最近遇到了这个。设置的Proxy-Authorization和Authorization标头中的哪个取决于客户端正在与之通信的服务器。如果是Web服务器，则需要设置授权，如果是代理，则必须设置Proxy-Authorization标头

经过大量研究，此代码对我而言适用。您将需要安装请求npm软件包。

var url = "http://api.example.com/api/v1/?param1=1&param2=2";
var auth = "Basic " + new Buffer(username + ":" + password).toString("base64");
exports.checkApi = function (req, res) {
    // do the GET request
    request.get({
        url: url,
        headers: {
            "Authorization": auth
        }
    }, function (error, response, body) {
        if(error)
       { console.error("Error while communication with api and ERROR is :  " + error);
       res.send(error);
    }
        console.log('body : ', body);
        res.send(body);      

    });    
}
