如何在java中阅读一个post包的正文
这个问题在这里已经有了答案：
如果你使用Java 8，你可以做
List<String> content = BR.lines().collect(Collectors.toList());
否则，你可以做
List<String> content = new ArrayList<>();
String line;
while((line = BR.readLine()) != null) {
content.add(line);
}
然后解析/格式化，因为您希望整体获得响应。
BR.readLine()只返回第一行; 您需要遍历BufferedReader来读取所有行。 一种可能的方式是：
String fullMessage;
String aux;
do{
aux = BR.readLine();
fullMessage = fullMessage.concat(aux);
}while(aux != null);
这只是一个例子来说明这个想法。
阅读文档：https：//docs.oracle.com/javase/7/docs/api/java/io/BufferedReader.html#readLine（）
java 7+的例子
String message = null;
//Try with resources, java will handle the closing of the stream, event if exception is thrown.
try ( InputStreamReader inputStream = new InputStreamReader(socket.getInputStream());
BufferedReader bufferReader = new BufferedReader(inputStream);) {
String aux = null;
do {
aux = bufferReader.readLine();
message = message.concat(aux);
} while (aux != null);
} catch (IOException e) {
System.out.println("Failed to read input stream from socket");
}
System.out.println("Message: " + message);
对于旧版本的Java，您可以使用：
InputStreamReader inputStream = null;
BufferedReader bufferReader = null;
String message = null;
try {
inputStream = new InputStreamReader(socket.getInputStream());
bufferReader = new BufferedReader(inputStream);
String aux = null;
do {
aux = bufferReader.readLine();
message = message.concat(aux);
} while (aux != null);
inputStream.close();
bufferReader.close();
} catch (IOException e) {
//Read throws IOException, don't just use Exception (this could hide other exceptions that you are not treating).
System.out.println("Failed to read input stream from socket");
} finally{
//Use 2 try-catch, if you only use one and the first fails, the second will never close.
try{inputStream.close();}catch(IOException ioe){}
try{bufferReader.close();}catch(IOException ioe){}
}
System.out.println("Message: "+message);
编辑：对不起追加是为StringBuffer和StringBuilder，我很抱歉。
编辑2：增加了2个更多信息的例子。
