Node.js 通过http调用外部接口

通过http.request发送带参数的post请求

data：发送的内容

opt：描述将要发出的请求

data：事件在数据到达时被触发

end：请求结束时触发

error：发生错误时被触发

var http = require("http");

var data = {username:"hello",password:"123456"};
data = JSON.stringify(data);
//data = require('querystring').stringify(data);

var opt = {
    host:'localhost',
    port:'8080',
    method:'POST',
    path:'/loginForeign.jspx',
    headers:{
        "Content-Type": 'application/json',
        "Content-Length": data.length
    }
}

var body = '';
var req = http.request(opt, function(res) {
    console.log("response: " + res.statusCode);
    res.on('data',function(data){
        body += data;
    }).on('end', function(){
        console.log(body)
    });
}).on('error', function(e) {
    console.log("error: " + e.message);
})
req.write(data);
req.end();
