Android SocketException-无法从服务器接收信息

[英]Android SocketException - Information not getting received from server

问题描述

I am trying to send a server json and get json in return to display in listview. 我正在尝试发送服务器json并获取json作为返回以显示在listview中。 The listview is taken care of by the refreshViewModels() method. listview由refreshViewModels（）方法处理。 The json string I'm sending is on this line of code: 我要发送的json字符串在以下代码行中：

outputJSONserv = "{\\"to\\":\\"broadcast\\",\\"type\\":\\"1\\",\\"payload\\":"+outputJSON+"}"; outputJSONserv =“ {\\”至\\“：\\”广播\\“，\\”类型\\“：\\” 1 \\“，\\”有效载荷\\“：” + outputJSON +“}” ;; where outputJSON is a json string. 其中outputJSON是json字符串。

When I send this string I do get a string back on one phone but not the other. 当我发送此字符串时，我确实在一个电话上得到了一个字符串，但在另一部电话上却没有。 I am getting a warning in the logcat that says it is an error that has to do with a SocketException for my output json. 我在logcat中收到警告，说这是我的输出json与SocketException有关的错误。 Here are the two logcats to show what is happening and to shoew details about the SocketException: 这是两个日志猫，它们用于显示正在发生的事情以及有关SocketException的详细信息：

Here are my conversions methods: 这是我的转换方法： 

public String ConvertByteArrayToString(byte[] b) {

}

public byte[] ConvertStringToByteArray(String str) { 
    // string to byte[]
    byte[] bytes = str.getBytes();
    return bytes;
}

Here are the methods I'm using to send and receive json strings: 这是我用来发送和接收json字符串的方法： 

public void sendBytes(byte[] myByteArray, int start, int len) throws IOException {
    if (len < 0)
        throw new IllegalArgumentException("Negative length not allowed");
    if (start < 0 || start >= myByteArray.length)
        throw new IndexOutOfBoundsException("Out of bounds: " + start);
    // Other checks if needed.

    // May be better to save the streams in the support class;
    // just like the socket variable.

    OutputStream out = socket.getOutputStream(); 
    DataOutputStream dos = new DataOutputStream(out);

    dos.writeInt(len);
    if (len > 0) {
        dos.write(myByteArray, start, len);
    }

    //OutputStream out = socket.getOutputStream(); //COMMENTED THIS OUT

    //DataOutputStream dos = new DataOutputStream(out); //COMMENTED THIS OUT

    /*dataOutputStream.writeInt(len);    //COMMENTED THIS OUT
    if (len > 0) {
        dataOutputStream.write(myByteArray, start, len);
    }*/
}

public static byte[] getBytesFromInputStream(InputStream is) throws IOException {
        // Get the size of the file
        int length = is.available();

        if (length > Integer.MAX_VALUE) {
        // File is too large
        }

        // Create the byte array to hold the data
        byte[] bytes = new byte[(int) length];

        // Read in the bytes
        int offset = 0;
        int numRead = 0;
        while (offset < bytes.length
        && (numRead = is.read(bytes, offset, bytes.length - offset)) >= 0) {
        offset += numRead;
        }
        // Ensure all the bytes have been read in
        if (offset < bytes.length) {
        throw new IOException("Could not completely stream ");
        }
        // Close the input stream and return bytes
        is.close();
        return bytes;
}

SocketException: socket is closed means that you closed the socket and then continued to use it. SocketException: socket is closed意味着您已关闭套接字，然后继续使用它。 It's a bug in your code. 这是您代码中的错误。 You're probably closing one of the streams and then still trying to use the other one: closing either stream closes the other stream and the socket. 您可能正在关闭其中一个流，然后仍然尝试使用另一个流：关闭任一流会关闭另一个流和套接字。

You are also misusing available(): see the Javadoc. 您还误用了available（）：请参阅Javadoc。 It doesn't do what you are using it for, which is specifically noted in the Javadoc as invalid. 它不执行您的用途，这在Javadoc中特别指出为无效。
