我在.net 中开发了一个网络服务,这里是

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
// [System.Web.Script.Services.ScriptService]
public class DataManipulationService : System.Web.Services.WebService
{
    [WebMethod]
    public void InsertData()
    {
        SQLConnectionManager conn = new SQLConnectionManager();

        string qry = "INSERT INTO TEST_TABLE(Id, Name) VALUES(3, 'Ibbi')";

        SQLOperationManager op = new SQLOperationManager(qry);
        int rowsAffected = op.ExecuteQuery();
    }
}

我正在尝试从android调用这个web方法,就像这样

public class WebDataManipulator {

private final String NAMESPACE = "http://tempuri.org/";
private final String URL = "http://localhost/DataManipulationService.asmx?WSDL";
private final String METHOD = "InsertData";
private final String SOAP_ACTION = "http://localhost/DataManipulationService.asmx?op=InsertData";

public void insertData() {
    SoapObject request = new SoapObject(NAMESPACE, METHOD);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);

    System.out.println(request);
    HttpTransportSE androidHttp = new HttpTransportSE(URL);


    try {
        androidHttp.call(SOAP_ACTION, envelope);
    } catch(Exception ex) {
        ex.printStackTrace();
    }
}

}

我已经在 .net 中测试了我的 Web 服务并且它工作正常,但是当我在 android 上运行它时,什么都没有发生.. 我没有得到任何异常,也没有它的功能。为什么?这是我的日志猫

这就是我编写客户端代码的方式

if(isNetworkAvailable()) {
   WebDataManipulator webDM = new WebDataManipulator();
   webDM.insertData();
   System.out.println("connected");
}

webserviceurl 以“localhost”开头,这是从 android 的角度来看 android 设备。将 localhost 替换为 androiddevice 可以看到的 ip 地址(即可以从 android web 浏览器调用)

我会在这里回答我自己的问题,我正在写我为让它工作所做的步骤。

  1. 确保您在 IIS 中正确托管了 Web 服务。你可以参考这个链接

    托管服务后,如果您发现在您的计算机上无法访问该服务,请执行第 2 步。

  2. 你需要在这里做两件事,

    1. 使 asp.net 出现在 IIS 管理器中。请参阅此处的链接
    2. 修改web.config文件,添加httpGet和httpPost。这里的例子
  3. 允许服务从远程机器调用它的 web 方法。请参阅此处的链接

  4. 确保防火墙没有阻止对您的计算机的访问。您可以定义新规则或禁用防火墙以查看是否有效。

按照上面的步骤,我现在可以在安卓设备上调用我的服务了。
