基于HttpClient在HTTP协议接口测试中的使用(详解)_Java

http协议的接口测试中，使用到最多的就是get请求与post请求，其中post请求有form参数提交请求与raw请求，下面我将结合httpclient来实现一下这三种形式：

一、get请求: get请求时，参数一般是写在链接上的，代码如下：

public void get(string url){
  closeablehttpclient httpclient = null;
  httpget httpget = null;
  try {
    httpclient = httpclients.createdefault();
    requestconfig requestconfig = requestconfig.custom().setsockettimeout(20000).setconnecttimeout(20000).build();   
    httpget = new httpget(url);
    httpget.setconfig(requestconfig);
    closeablehttpresponse response = httpclient.execute(httpget);
    httpentity httpentity = response.getentity();
    system.out.println(entityutils.tostring(httpentity,"utf-8"));
  } catch (clientprotocolexception e) {
    e.printstacktrace();
  } catch (ioexception e) {
    e.printstacktrace();
  }finally{
    try {
      if(httpget!=null){
        httpget.releaseconnection();
      }
      if(httpclient!=null){
        httpclient.close();
      }
    } catch (ioexception e) {
      e.printstacktrace();
    }
  }
}

如果想把参数不写在链接上，单独的传进去，则可以这样：

public void get(string url, map<string, string> params){
  closeablehttpclient httpclient = null;
  httpget httpget = null;
  try {
    httpclient = httpclients.createdefault();
    requestconfig requestconfig = requestconfig.custom().setsockettimeout(20000).setconnecttimeout(20000).build();
    string ps = "";
    for (string pkey : params.keyset()) {
      if(!"".equals(ps)){
        ps = ps + "&";
      }
      ps = pkey+"="+params.get(pkey);
    }
    if(!"".equals(ps)){
      url = url + "?" + ps;
    }
    httpget = new httpget(url);
    httpget.setconfig(requestconfig);
    closeablehttpresponse response = httpclient.execute(httpget);
    httpentity httpentity = response.getentity();
    system.out.println(entityutils.tostring(httpentity,"utf-8"));
  } catch (clientprotocolexception e) {
    e.printstacktrace();
  } catch (ioexception e) {
    e.printstacktrace();
  }finally{
    try {
      if(httpget!=null){
        httpget.releaseconnection();
      }
      if(httpclient!=null){
        httpclient.close();
      }
    } catch (ioexception e) {
      e.printstacktrace();
    }
  }
}

二、post请求的表单提交方式，代码如下：

public void post(string url, map<string, string> params){
  closeablehttpclient httpclient = null;
  httppost httppost = null;
  try {
    httpclient = httpclients.createdefault();
    requestconfig requestconfig = requestconfig.custom().setsockettimeout(20000).setconnecttimeout(20000).build();
    httppost = new httppost(url);
    httppost.setconfig(requestconfig);
    list<namevaluepair> ps = new arraylist<namevaluepair>();
    for (string pkey : params.keyset()) {
      ps.add(new basicnamevaluepair(pkey, params.get(pkey)));
    }
    httppost.setentity(new urlencodedformentity(ps));
    closeablehttpresponse response = httpclient.execute(httppost);
    httpentity httpentity = response.getentity();
    system.out.println(entityutils.tostring(httpentity,"utf-8"));
  } catch (clientprotocolexception e) {
    e.printstacktrace();
  } catch (ioexception e) {
    e.printstacktrace();
  }finally{
    try {
      if(httppost!=null){
        httppost.releaseconnection();
      }
      if(httpclient!=null){
        httpclient.close();
      }
    } catch (ioexception e) {
      e.printstacktrace();
    }
  }
}

三、 post请求的raw参数传递：

public void post(string url, string body){
  closeablehttpclient httpclient = null;
  httppost httppost = null;
  try {
    httpclient = httpclients.createdefault();
    requestconfig requestconfig = requestconfig.custom().setsockettimeout(20000).setconnecttimeout(20000).build();
    httppost = new httppost(url);
    httppost.setconfig(requestconfig);
    httppost.setentity(new stringentity(body));
    closeablehttpresponse response = httpclient.execute(httppost);
    httpentity httpentity = response.getentity();
    system.out.println(entityutils.tostring(httpentity,"utf-8"));
  } catch (clientprotocolexception e) {
    e.printstacktrace();
  } catch (ioexception e) {
    e.printstacktrace();
  }finally{
    try {
      if(httppost!=null){
        httppost.releaseconnection();
      }
      if(httpclient!=null){
        httpclient.close();
      }
    } catch (ioexception e) {
      e.printstacktrace();
    }
  }
}
