使用到的jar：
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
工具方法：
public class HttpRequest {
private static final Logger logger = LoggerFactory.getLogger(HttpRequest.class);
public static String httpRequest(String httpUrl, String requestMethod,String outputStr) {
StringBuffer buffer = new StringBuffer();
try {
URL url = new URL(httpUrl);
URLConnection rulConnection = url.openConnection();
HttpURLConnection httpUrlConnection = (HttpURLConnection) rulConnection;
httpUrlConnection.setDoOutput(true);
httpUrlConnection.setDoInput(true);
httpUrlConnection.setUseCaches(false);
httpUrlConnection.setRequestProperty("Content-Type",
"application/json");
httpUrlConnection
.setRequestProperty("POST", "/violations HTTP/1.1");
httpUrlConnection.setRequestMethod(requestMethod);
httpUrlConnection.connect();
if (null != outputStr) {
OutputStream outputStream = httpUrlConnection.getOutputStream();
outputStream.write(outputStr.getBytes("UTF-8"));
outputStream.close();
}
InputStream inputStream = httpUrlConnection.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(
inputStream, "UTF-8");
BufferedReader bufferedReader = new BufferedReader(
inputStreamReader);
String str = null;
while ((str = bufferedReader.readLine()) != null) {
buffer.append(str);
}
bufferedReader.close();
inputStreamReader.close();
inputStream.close();
inputStream = null;
httpUrlConnection.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
return buffer.toString();
}
}
调用方法：
String jsonString = HttpRequest.httpRequest(urlIn, “POST”, object.toString());
返回的是json格式字符串，通过解析结果串得到反馈结果。。。。。
