java - org.json.JSONException : Unterminated string at character

Question

通过传递字符串创建 JSONObject 时出现错误。

Org.json.JSONException: Unterminated string at character

我的 JSON 字符串是:

{"Count":741,"Data":[{rec1....},{rec2...}, etc]}

这似乎只发生在 Linux 上，因为我在 Windows 中开发并且运行得很好。此外，问题似乎源于字符串太长。我将数组削减了一半以上，问题就消失了。

我可以做什么来解决这个问题或者是否有解决方法？

如果您在Android studio中使用AsyncTask来与mysql或其他数据库中的HttpURLConnectionin进行查询。有一个名为“String downloadUrl(String myurl) ”的方法，有一个变量“int len = 500;”对于读取输入流中的数据，您可以将此变量更改为需要读取的数字字符。

 private String downloadUrl(String myurl) throws IOException {
    Log.i("URL",""+myurl);
    myurl = myurl.replace(" ","%20");
    InputStream is = null;
    // Only display the first 500 characters of the retrieved
    // web page content.
    <b>int len = 1500; </b>

    try {
        URL url = new URL(myurl);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setReadTimeout(10000 /* milliseconds */);
        conn.setConnectTimeout(15000 /* milliseconds */);
        conn.setRequestMethod("GET");
        conn.setDoInput(true);
        // Starts the query
        conn.connect();
        int response = conn.getResponseCode();
        Log.d("respuesta", "The response is: " + response);
        is = conn.getInputStream();

        // Convert the InputStream into a string
        String contentAsString = readIt(is, len);
        return contentAsString;

        // Makes sure that the InputStream is closed after the app is
        // finished using it.
    } finally {
        if (is != null) {
            is.close();
        }
    }
}
