使用Httpclient进行接口测试 / 憋错料

下载Httpclient包：http://apache.fayea.com//httpcomponents/httpclient/binary/httpcomponents-client-4.5-bin.zip

刚安装完eclipse，新建项目interfaceTest，新建类InterfaceTest，参照资料：http://blog.csdn.net/wangpeng047/article/details/19624529

导入Httpclient包：

点击菜单栏的project-点properties属性，然后在 Java build path菜单中点libraries-点击add External jars,找到Httpclient的zip包的路径，导入该包。成功后，该项目下referenced libraries目录下出现了Httpclient包的相关内容。

想直接粘参考资料的代码来的，但是，第一句package XXX就把我搞蒙了，先查了一下：http://www.cnblogs.com/mengdd/archive/2012/12/27/2836412.html，里面说“如果定义类的时候没有使用package指定包名，则Java认为类位于默认包里面（default package）。”

嗯，那现在开始吧（以下代码是抄的wangpeng047的，略有改动）：

啊嘚嘚。其实我没验证过这些代码~我也不是这么搞的。刚把httpclient包引入，盖爷就过来帮忙导入了好多我不认识的包，叭叭叭敲了几行代码，就告诉我，你改接口地址和键值对，就可以进行测试了：

package interfaceTest_1;

import java.util.HashMap;
import java.util.Map;

import com.alibaba.fastjson.JSON;

public class InterfaceTest {

public static void main(String[] args) {
// TODO Auto-generated method stub
Map<String,Object> m = new HashMap<String,Object>();
m.put("a",1);
m.put("",1);
String res = HTTPUtil.postJson("http://www.baidu.com", JSON.toJSONString(m));
System.out.println(res);
}

}

感谢盖爷的技术支持，我后续再自己试试这个过程~
