node作为中间服务层如何发送请求(发送请求的实现方法详解)

var http = require('http'); var qs = require('querystring'); var data = {   a: 123,   time: new Date().getTime()};//这是需要提交的数据 var content = qs.stringify(data); var options = {   hostname: '127.0.0.1',   port: 10086,   path: '/pay/pay_callback?' + content,   method: 'GET' };   var req = http.request(options, function (res) {   console.log('STATUS: ' + res.statusCode);   console.log('HEADERS: ' + JSON.stringify(res.headers));   res.setEncoding('utf8');   res.on('data', function (chunk) {     console.log('BODY: ' + chunk);   }); });   req.on('error', function (e) {   console.log('problem with request: ' + e.message); });   req.end();

var http = require('http'); var qs = require('querystring'); var post_data = {   a: 123,   time: new Date().getTime()};//这是需要提交的数据 var content = qs.stringify(post_data); var options = {   hostname: '127.0.0.1',   port: 10086,   path: '/pay/pay_callback',   method: 'POST',   headers: {     'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'   } };   var req = http.request(options, function (res) {   console.log('STATUS: ' + res.statusCode);   console.log('HEADERS: ' + JSON.stringify(res.headers));   res.setEncoding('utf8');   res.on('data', function (chunk) {     console.log('BODY: ' + chunk);   }); });   req.on('error', function (e) {   console.log('problem with request: ' + e.message); }); // write data to request body req.write(content); req.end();
