java以json格式向后台服务器接口发送请求的实例
代码如下：
importjava.io.BufferedReader;
importjava.io.DataOutputStream;
importjava.io.IOException;
importjava.io.InputStreamReader;
importjava.net.HttpURLConnection;
importjava.net.URL;
importnet.sf.json.JSONObject;
publicclassInterfaceRequest{
//模拟向腾讯云发送接口
//接口
privatefinalstaticStringURL="https://console.tim.qq.com/v4/im_open_login_svc/account_import?";
/**
*@paramargs
*@throwsIOException
*/
publicstaticvoidmain(String[]args)throwsIOException{
//TODOAuto-generatedmethodstub
//连接服务器
HttpURLConnectionconnection=connection(URL);
DataOutputStreamout=newDataOutputStream(
connection.getOutputStream());
JSONObjectobj=newJSONObject();
obj.element("Identifier","hehe");
System.out.println(obj.toString());
//向腾讯请求传入编码为UTF-8格式的json数据
out.write(obj.toString().getBytes("UTF-8"));
out.flush();
out.close();
//获得服务器返回的结果
BufferedReaderreader=newBufferedReader(newInputStreamReader(
connection.getInputStream()));
Stringlines;
StringBuffersb=newStringBuffer("");
while((lines=reader.readLine())!=null){
lines=newString(lines.getBytes(),"utf-8");
sb.append(lines);
}
reader.close();
}
publicstaticHttpURLConnectionconnection(StringURL
)throwsIOException{
URLurl=newURL(URL);
HttpURLConnectionconnection=(HttpURLConnection)url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("POST");
connection.setUseCaches(false);
connection.setInstanceFollowRedirects(true);
connection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded;charset=UTF-8");
connection.connect();
returnconnection;
//TODOAuto-generatedmethodstub
}
}
