java.net.SocketException : socket failed: EACCES (Permission denied) 异常

Question

我已经搜索了所有解决方案并将其应用到我的项目中。但他们没有工作。我拒绝了此权限。我已将所有这些可能的权限放入 list 文件中。请告诉我我的项目有什么问题。

public static void getGetResponse() {
        InputStream inputStream = null;
        try {
            URL url = new URL("http://120.26.89.113:8080/common/qiniuToken");
            HttpURLConnection connection = (HttpURLConnection)url.openConnection();
            connection.setRequestMethod("GET");          
            String userPassword = "wehelper:***********";
            byte[] encodedBytes = Base64.encode(userPassword.getBytes(), 0);
            connection.setRequestProperty("Authorization", "Basic " + encodedBytes);
            connection.connect();
            int resCode = connection.getResponseCode();
            if (resCode == 200) {
                inputStream = connection.getInputStream();
            }

            BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
            StringBuilder out = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                out.append(line);
            }
            System.out.println(out.toString());//Prints the string content read from input stream
            Log.d("myApp",out.toString());
            reader.close();

        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

和我的 manifest.xml

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/MyMaterialTheme">
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

你的 <uses-permission>元素在错误的位置。他们需要在 <application> 的之外元素，作为根的直接子元素 <manifest>元素:

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/MyMaterialTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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