JAVA模拟发送HTTP请求

/*

* 得到返回的内容

public static String getResult(String urlStr, String content) {

URL url = null;

HttpURLConnection connection = null;

try {

url = new URL(urlStr);

connection = (HttpURLConnection) url.openConnection();//新建连接实例

connection.setDoOutput(true);//是否打开输出流 true|false

connection.setDoInput(true);//是否打开输入流true|false

connection.setRequestMethod("POST");//提交方法POST|GET

connection.setUseCaches(false);//是否缓存true|false

connection.connect();//打开连接端口

DataOutputStream out = new DataOutputStream(connection.getOutputStream());//打开输出流往对端服务器写数据

out.writeBytes(content);//写数据,也就是提交你的表单 name=xxx&pwd=xxx

out.flush();//刷新

out.close();//关闭输出流

BufferedReader reader = new BufferedReader(new InputStreamReader(connection

.getInputStream(), "utf-8"));//往对端写完数据 对端服务器返回数据 ,以BufferedReader流来读取

StringBuffer buffer = new StringBuffer();

reader.close();

return buffer.toString();

} catch (IOException e) {

e.printStackTrace();

} finally {
