在Android中使用WCF服务时出错

标签: c# java android .net wcf

我正在尝试使用WCF服务将数据发布到我的数据库,但似乎无法确定我的代码有什么问题,我尝试了不同的解决方案,但所有这些似乎都失败了。我是android开发的新手,不知道如何调试。请帮我...
这是我的代码:

WCF服务:

[ServiceContract]
public interface IAllocationService
{
    [OperationContract]
    [WebInvoke(
        Method = "POST",
        UriTemplate = "StrongestWifi",
        BodyStyle = WebMessageBodyStyle.WrappedRequest,
        ResponseFormat = WebMessageFormat.Json,
        RequestFormat = WebMessageFormat.Json)]
    void UpdateStrongestWifi(myWifiClass myWifiClass);

}

[DataContract]
public class myWifiClass
{
    [DataMember(Name = "Time")]
    public string Time
    {
        get;
        set;
    }
    [DataMember(Name = "SignalStrength")]
    public string SignalStrength
    {
        get;
        set;
    }
    [DataMember(Name = "SSID")]
    public string SSID
    {
        get;
        set;
    }

Android代码:

public void onGetWebService(View v)
{
    HttpPost request = new HttpPost(SERVICE_URI + "/StrongestWifi");
    request.setHeader("Accept", "application/json");            
    request.setHeader("Content-type", "application/json");
    JSONStringer getWifiInfo;
    try {
        getWifiInfo = new JSONStringer()
            .object()
                .key("myWifiClass")
                    .object()
                        .key("Time").value("TIME")                                  
                        .key("SignalStrength").value("Strength")
                        .key("SSID").value("ID")
                    .endObject()
                .endObject();

    StringEntity entity = new StringEntity(getWifiInfo.toString());

    request.setEntity(entity);

    // Send request to WCF service
    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpResponse response = httpClient.execute(request);
    Log.d("WebInvoke", "Saving : " + response.getStatusLine().getStatusCode());
    }
    catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

不要在主线程上进行网络调用,因为它可能会导致应用程序 .try在 asyntask 中调用此httpClient.execute(请求)或使用 runnable 线程。
