需要对业务中最重要的接口做拉力测试, 简单的说, 就是一个5000*5000的循环扫描.

总结: 访问http

  • 复杂的原生方法
//复杂的方法
var url = 'http://graph.facebook.com/517267866/?fields=picture';

http.get(url, function(res){
    var body = '';

    res.on('data', function(chunk){
        body += chunk;
    });

    res.on('end', function(){
        var fbResponse = JSON.parse(body);
        console.log("Got a response: ", fbResponse.picture);
    });
}).on('error', function(e){
      console.log("Got an error: ", e);
});
  • request方法
var request = require('request') //http处理库request
const url='http://trainapi.vip.elong.com/home/getStartEndStation'
    //http访问的参数, 这里要参数化.
const restring={ 'startDate': date, 
    'startStation': star,
    'endStation': end,
}
request.get(url,  { qs: restring },	httpr(error, response, body))
//request.get request.post
//参数可以指定json 或者qs
//一句话写成下面这样.
request.get({url: "http://localhost:3000/my-api-controller", 
             qs: {url: url}},
            function(error, response, body){
               console.log(body);
            });
// 加一个超时设置: timeout.
  • post json
var request = require('request');

request.post(
    'http://www.yoursite.com/formpage',
    { json: { key: 'value' } },
    function (error, response, body) {
        if (!error && response.statusCode == 200) {
            console.log(body)
        }
    }
);
  • 加上管道啥的
//最简单的
var request = require('request');
request('http://www.google.com', function (error, response, body) {
  console.log('error:', error); // Print the error if one occurred
  console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
  console.log('body:', body); // Print the HTML for the Google homepage.
});

//管道到文件
request('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))
//文件到http
fs.createReadStream('file.json').pipe(request.put('http://mysite.com/obj.json'))
//文件和管道互相
request.get('http://google.com/img.png').pipe(request.put('http://mysite.com/img.png'))

log文件处理

  • 必须要分每一天的log
const today = new Date().toJSON().slice(0,10) //拿到2017-08-11, 下面log文件.
  • 文件的追加式写法, 直接write是覆盖
fs.appendFile("./log/每天一个log"+today+".log","=这个参数是拼接的log文件内容="+body+"\n" , function(err) {/*这是回调函数.*/})

request其实不简单

他有n多参数, 能力爆表

https://github.com/request/request#requestoptions-callback
var request = require('request');

var propertiesObject = { field1:'test1', field2:'test2' };

request({url:url, qs:propertiesObject}, function(err, response, body) {
  if(err) { console.log(err); return; }
  console.log("Get response: " + response.statusCode);
});
