java.io.EOFException的和connection.getInputStream（）

如何解决这个probleme我不能让我的InputStream InputStream inputStream = connection.getInputStream();java.io.EOFException的和connection.getInputStream（）

功能：

StringBuffer result = new StringBuffer(""); 
    try { 
     URL url = new URL(urlString); 
     HttpURLConnection connection = (HttpURLConnection) url.openConnection(); 
     connection.setRequestProperty("User_Agent", ""); 
     connection.setRequestMethod("POST"); 
     connection.setDoInput(true); 
     connection.connect(); 
     InputStream inputStream = connection.getInputStream(); 
     BufferedReader rd = new BufferedReader(new InputStreamReader(inputStream)); 

     String line = ""; 
     while ((line = rd.readLine()) != null) { 
      result.append(line); 
     } 

    } catch (IOException e) { 
     e.printStackTrace(); 
     Log.e("REQUEST Result", "IOException = " + e.getMessage()); 
    } 
    Log.d("REQUEST Result", "result = " + result); 
    return result; 
}

的logcat：

您是否阅读[this]（https://docs.oracle.com/javase/7/docs/api/java/io/BufferedReader.html#readLine（））在读取行之前检查null值。 – t0mm13b

在尝试从中获取InputStream之前，应该检查HttpURLConnection是否为空。

当越来越从HttpURLConnection的输入流：

InputStream inputStream = new BufferedInputStream(connection.getInputStream());

我不认为这是绝对必要为你做connection.connect()你已经做了url.openConnection()后;

我还注意到您正在发布内容。从Android开发者page on HttpURLConnection：

为了获得最佳性能，你应该调用要么setFixedLengthStreamingMode（INT）时，车身长度事先已知或setChunkedStreamingMode（INT）时，它不是。否则HttpURLConnection将被强制在发送之前缓冲内存中的完整请求体，浪费（并可能耗尽）堆并增加延迟。

该页面可能解决您使用该类的任何其他问题。
