Interface Test (java+testng+ant+jenkins) First Java

This tutorial is for people with basic Java language skills to learn

1, preparation tools: JDK, Eclipse (specific installation please Baidu)

2. In eclipse, create the project as follows

　　

3, set the project code UTF-8

Project name right-click--properties--resource--other:utf-8

4, then create a class:httprequest, put in the code

(The interface can be called without scrutiny implementation)

5. In Demo1, call the interface that sent the GET request

　　

Request parameters from Google Translate

In this interface, you can view the interface data by pressing F12, entering and.

The picture in the red box, the question mark before the URL, the question mark after the request data.

 PackageCOM.LX;Importcom.lx.HttpRequest; Public classDemo1 { Public Static voidMain (string[] args) {//The first parameter is the URL, the second parameter is the request dataString s = httprequest.sendget ("Https://translate.google.cn/translate_a/single", "CLIENT=T&SL=EN&TL=ZH-CN &hl=zh-CN&dt=at&dt=bd&dt=ex&dt=ld&dt=md&dt=qca&dt=rw&dt=rm&dt=ss& Dt=t&ie=utf-8&oe=utf-8&otf=1&ssel=0&tsel=0&kc=1&tk=640089.1025185&q=and ");    System.out.println (s); }}

6, the operation result is

Consistent with the data in the Google translation response, the test passed
