java 调用第三方接口

1.在配置文件中准备好url和 所需的参数

String param=xxxx;

String url =xxx;

2.创建http请求

try {

HttpClient httpClient = httpClientBuilder.create().builder();

HttpGet httpGet = new HttpGet（url）；

HttpResponse response = httpClient.excute(httpGet);

/**解析返回的值*/

JSONObject resultJsonObject = null;

String line =null;

try {

StringBuffer entityStringBuilder =new StringBuffer();

BufferedReader b = new BufferedReader(new InputStreamReader(response.getEntity().getContent()),8*1024);

while((line=b.readline())!=null){

entityStringBuilder.append(line+"/n");

}

resultJsonObject  = new JSONObject(entityStringBuilder.toString());

result=resultJsonObject.toString();

}catch(JSONException e){
e.printStackTrace();

}

}catch(IOException e){

e.printStackTrace();

}

 

得到的result 就是你想要的返回值  代码复制下来改改就能用了
