我正在尝试使用 WCF 服务将数据发布到我的数据库,但似乎无法弄清楚我的代码有什么问题,我尝试了不同的解决方案,但似乎都失败了。我是 android 开发新手,不知道如何调试。请帮助我......
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;
}
安卓代码:
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();
}
}
