Android中的HttpURLConnection网络请求方式

post请求

<span style="white-space:pre">	</span>String path="http://www.baidu.com";
String param="hehehe";

//新建一个URL对象
try {
URL url = new URL(path);
// 打开一个HttpURLConnection连接
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
//设置请求方式请求post
conn.setRequestMethod("POST");
// Post请求必须设置允许输出
conn.setDoOutput(true);
// Post请求不能使用缓存
conn.setUseCaches(false);
// 配置请求Content-Type  Content-Length
conn.addRequestProperty("Content-Length", param.length()+"");
conn.addRequestProperty("Content-Type", "application/x-www-form-urlencoded");
OutputStream out = conn.getOutputStream();
out.write(param.getBytes());
// 开始连接
conn.connect();
int code = conn.getResponseCode();
// 判断请求是否成功
if(code==200){
InputStream in= conn.getInputStream();
//把字节流转化成字符流  InputStreamReader
InputStreamReader isr=new InputStreamReader(in);
//把字符流转换成缓冲字符流
BufferedReader br=new BufferedReader(isr);
// 创建一个StringBuffer
StringBuffer sb=new StringBuffer();
String str="";
while((str=br.readLine())!=null){

}

}

} catch (Exception e) {
