Question

当我使用我的数据计划并且我的应用程序工作正常时，我的脚本具有完全访问权限，只有当我切换到Wi-Fi时，我的脚本才会出现500内部服务器错误。

我正在使用php脚本，我的应用程序使用：

访问它

    public JSONObject getHttpResponse(String domUrl){

    String parsedString = "";

    //Log.d("Tag Name", "gggg");
    try {

        URL url = new URL(domUrl);
        URLConnection conn = url.openConnection();

        HttpURLConnection httpConn = (HttpURLConnection) conn;
        httpConn.setAllowUserInteraction(false);
        httpConn.setInstanceFollowRedirects(true);
        httpConn.setRequestMethod("GET");
        httpConn.connect();

        InputStream is = httpConn.getInputStream();
        parsedString = convertinputStreamToString(is);

        httpConn.disconnect();
        //((HttpURLConnection) conn).disconnect();

        if(parsedString.length() > 0){
            return getJSONResponseObject(parsedString);
        }

        //Log.d("Tag Name xfgfgxfgxfg", parsedString);

    } catch (Exception e) {
        e.printStackTrace();
    }

    return null;
}

我的AndroidManifest.xml文件包含：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

我得到的错误：

有人可以提出建议吗？

我有一个类似的问题。

添加此行

   urlConnection.setRequestProperty("Accept-Encoding", "identity");

设置Accept-Encoding请求标头显式禁用自动解压缩并保持响应头完整无缺;根据响应的Content-Encoding标头，调用者必须根据需要处理解压缩。通过android HttpUrlconnection引用http://developer.android.com/reference/java/net/HttpURLConnection.html

在Android中使用Wi-Fi时出现FileNotFoundException
