Http与网络通信(GET和POST方式)_get通信中指什么-优快云博客

本文详细介绍了如何使用Java通过HTTP的GET和POST方式与网络进行数据交互。GET请求主要用于从服务器获取数据，而POST请求则用于向服务器发送数据。文章提供了具体的Java代码示例，包括设置请求属性、读取响应内容等关键步骤。

1. 使用Http的Get方式读取网络数据
URL url = new URL("");
URLConnection connection = url.openConnection();
InputStream is = connection.getInputStream();
InputStreamReader isr = new InputStreamReader(is,"UTF-8");
BufferedReader br = new BufferedReader(isr);
String line = null;
StringBuilder builder = new StringBuilder();
while((line=br.readLine())!=null){
builder.append(line);
}
br.close();
isr.close();
is.close();
System.out.println(builder.toString)
2. 使用Http的Post方式与网络交互通信
URL url = new URL("url");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.addRequestProperty("encoding","UTF-8");
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setRequestMethod("POST");

OutputStream os = connection.getOutputStream();
OutputStreamWriter osw = new OutputStreamWriter(os);
BufferedWriter bw = new BufferedWriter(osw);

bw.write("参数");
bw.flush();


InputStream is = connection.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);

String line =null;
StringBuilder builder =new StringBuilder();
while((line = br.readLine())!=null){
builder.append(line);
}
bw.close();
osw.close();
os.close();
br.close();
isr.close();
is.close();

System.out.println(builder.toString());
