本文介绍了一种使用Android发起POST请求的方法，并提供了详细的代码实现。通过设置连接超时时间、请求方式及输出参数等，实现了向指定URL发送POST请求并接收响应。

android用POST方式请求网络,多的不说了直接上代码

//请求代码

public static String Post(String string,String get,Context context)//string POST参数,get 请求的URL地址,context 联系上下文
	{
		
		try {
		String urldizhi=get; //请求地址
		URL url=new URL(urldizhi);
		HttpURLConnection conn = (HttpURLConnection) url.openConnection();
		conn.setConnectTimeout(50000);//超时时间
		conn.setRequestMethod("POST");
		conn.setDoOutput(true);
		conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
//		conn.setRequestProperty("User-Agent", Other.getUserAgent(context));
		OutputStreamWriter out = new OutputStreamWriter(conn.getOutputStream());
		out.write(string);
		out.flush();
		out.close();
		
		InputStream inputStream=conn.getInputStream();
		byte[] data=StreamTool.read(inputStream);
		html = new String(data, "utf-8");
		
		} catch (Exception e) {
			System.out.println("-----"+e);
			String string2="{\"success\":-1}";
			
			return string2;
		}
		return html;
	}

还有一个类我也贴出来

package com.sutong.feihua.http;


import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;
import java.io.OutputStream;


public class StreamTool {
