从移动应用程序调用localhost Web服务时出现访问被拒绝错误

Question

我正在构建Web服务，以便使用IIS 7在设备SQLite和服务器MS SQL数据库之间复制数据。从移动浏览器执行Web服务，而不会出现WiFi问题。执行transporte.call后，我收到访问被拒绝错误。我试图从三星Note Edge设备执行。

请注意，使用VB.Net我能够从网络上的另一台计算机成功使用这两种Web服务方法。

感谢。

Answer 1

在AndroidManifest.xml中，uses-permission标记应写在application标记之外。

您缺少清单中的INTERNET权限。这就是错误的原因。

<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" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

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

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

这是您要创建的请求。

<RetrieveS xmlns="http://192.168.0.2/">
  <s>string</s>
  <t>string</t>
</RetrieveS>

这是您创建上述请求的方式，

SoapObject  request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("s","sValue");
request.addProperty("t","tValue");
envelope.setOutputSoapObject(request);

如果您想获得回复XML，

HttpTransportSE transporte = new HttpTransportSE(URL);
transporte.debug = true;
try {
    transporte.call(SOAP_ACTION,envelope);

    String resultado = transporte.responseDump;
} catch (Exception e){
    e.printStackTrace();
    Toast.makeText(getBaseContext(),e.getMessage().toString(),Toast.LENGTH_LONG).show();
}
