nodejs发起HTTPS请求并获取数据

var https = require(‘https‘);
var zlib = require(‘zlib‘);

var post_data="………………";//请求数据
var reqdata = JSON.stringify(post_data);
var options = {
    hostname: ‘10.225.***.***‘,
    port: ‘8443‘,
    path: ‘/data/table/list‘,
    method: ‘POST‘,
    rejectUnauthorized: false,
    requestCert: true,
    auth: ‘admin:7584FD2E************‘,
    headers: {
        ‘username‘: ‘admin‘,
        ‘password‘: ‘7584FD2E************‘,
        ‘Cookie‘: ‘locale=zh_CN‘,
        ‘X-BuildTime‘: ‘2015-01-01 20:04:11‘,
        ‘Autologin‘: ‘4‘,
        ‘Accept-Encoding‘: ‘gzip, deflate‘,
        ‘X-Timeout‘: ‘3600000‘,
        ‘Content-Type‘: ‘Application/json‘,
        "Content-Length":reqdata.length
    }
};
var req = https.request(options, function (res) {
});
req.write(reqdata);
req.on(‘response‘, function (response) {
   switch (response.headers[‘content-encoding‘]) {
        case ‘gzip‘:
            var body = ‘‘;
            var gunzip = zlib.createGunzip();
            response.pipe(gunzip);    
            gunzip.on(‘data‘, function (data) {
                 body += data;
            });
            gunzip.on(‘end‘, function () {
                 var returndatatojson= JSON.parse(body);
                 req.end();
            });
            gunzip.on(‘error‘, function (e) {
                 console.log(‘error‘ + e.toString());
                 req.end();
            });
            break;
        case ‘deflate‘:
            var output = fs.createWriteStream("d:temp.txt");
            response.pipe(zlib.createInflate()).pipe(output);
            req.end();
            break;
        default:req.end();
            break;      
   }  
 });
req.on(‘error‘, function (e) {
    console.log(new Error(‘problem with request: ‘ + e.message));
    req.end();
    setTimeout(cb, 10);
});


//以上是nodejs中通过https请求获取数据的全过程。注意，options,需要有请求数据的长度，options需要加上‘Accept-Encoding‘: ‘gzip, deflate‘,返回的数据需要判断是哪种压缩方式，然后解压缩获取到数据。gunzip的end事件里的returndatatojson即是获取的数据.
