常见请求头,在post请求之 前先了解一下,请求相关的基础
关于post 请求的方式比get 多了很多配置,其实大致一样,本想将get示例和post写在一起,这个博客功能有时有问题 一直在灰色的编辑框中跳不出去,只能另起一篇博客。
private void doPost(String s) {
try {
// URl构建的是一上地址对象
URL url = new URL(UrlAddress);
// 创建一个连接
HttpURLConnection httpURLConnection =(HttpURLConnection) url.openConnection();
// 由于是post 请求需要配置参数
httpURLConnection.setDoInput(true);
httpURLConnection.setDoOutput(true);
// 配置请求头
httpURLConnection.setRequestMethod("POST");
// 配置请求是否有缓存
httpURLConnection.setDefaultUseCaches(false);
HttpURLConnection.setDefaultRequestProperty("Accept-Charset","UTF-8");
HttpURLConnection.setDefaultRequestProperty("Content-Type","application/x-www-form-urlencoded");
// 配置好了尝试连接准备
httpURLConnection.connect();
DataOutputStream outputStream = new DataOutputStream(httpURLConnection.getOutputStream());
// 拼接请求参数,比如条件,性别,
String content = "set="+s;
outputStream.write(content.getBytes());
outputStream.flush();
outputStream.close();
//以下的处理和get 一样了
if(httpURLConnection.getResponseCode() == 200){
InputStream is =httpURLConnection.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is));
StringBuffer Sbuffer = new StringBuffer();
String readLine = "";
while ((readLine = br.readLine())!=null){
Sbuffer.append(readLine);
}
is.close();
br.close();
httpURLConnection.disconnect();
Log.d("Text",Sbuffer.toString());
}
} catch (MalformedURLException e) {
throw new RuntimeException(e);
} catch (IOException e) {
throw new RuntimeException(e);
} finally {
}
} //dopost 方法方法结束
