我正在尝试让这段代码运行:
Silverlight 应用程序 xaml.cs:
private void SavePoiRequest(MyPushpin pin)
{
WebClient wc = new WebClient();
wc.Headers["Content-Type"] = "application/x-www-form-urlencoded";
wc.Encoding = Encoding.UTF8;
wc.UploadStringCompleted += new UploadStringCompletedEventHandler((sender, e) =>
{
if (e.Error != null)
{
return;
}
AddressTextBox.Text = e.Result;
});
String name = pin.Name;
String lat = pin.Location.Latitude.ToString().Replace(",",".");
String lng = pin.Location.Longitude.ToString().Replace(",",".");
String address = pin.Address;
String photodesc = pin.PhotoDesc;
String poistory = pin.Tag.ToString();
StringBuilder sr = new StringBuilder();
sr.Append("createpoi?name="+name+ "&lat=" + lat + "&lng=" + lng + "&adr=" + address + "&desc=" + photodesc + "&story=" + poistory);
String parameter = sr.ToString();
wc.UploadStringAsync(new Uri("http://localhost:80/"), "POST", parameter);
AddressTextBox.Text = parameter;
}
网络服务 CS:
[WebInvoke(UriTemplate = "createpoi?name={name}&lat={latitude}&lng={longitude}&adr={address}&desc={photodescription}&story={poistory}", Method = "POST")]
public String SetPoiPOST(string name, string latitude, string longitude, string address, string photodescription, string poistory)
{
int newid = -1;
POI_Man poimanager = new POI_Man();
MemoryStream resultstream = new MemoryStream();
if (!string.IsNullOrEmpty(name) &&
!string.IsNullOrEmpty(latitude) &&
!string.IsNullOrEmpty(longitude) &&
!string.IsNullOrEmpty(address) &&
!string.IsNullOrEmpty(photodescription) &&
!string.IsNullOrEmpty(poistory)
)
{
//newid = poimanager.CreatePOI_alt(address, name, photodescription, poistory);
newid = poimanager.CreatePOI(name, latitude, longitude, address, photodescription, poistory);
poimanager.Generate("xml");
resultstream = poimanager.WriteMessage(newid.ToString());
WebOperationContext.Current.OutgoingResponse.ContentType = "text/plain";
}
if (poimanager.NoError)
{
resultstream = poimanager.WriteMessage(newid.ToString());
WebOperationContext.Current.OutgoingResponse.ContentType = "text/plain";
//resultstream = (this.GetPoi(newid.ToString()) as MemoryStream);
}
else
{
resultstream = poimanager.WriteMessage("Beim anlegen des POI ist ein Fehler aufgetreten."
+ Environment.NewLine + "Haben Sie einen Parameter vergessen?");
WebOperationContext.Current.OutgoingResponse.ContentType = "text/plain";
}
return newid.ToString();
}
Web 服务不会从客户端获取任何信息。我做错了什么吗?
我可以通过 WebClient OpenWriteAsync 的 POST 请求联系服务器。但是我需要服务器对 lastID 的响应,所以我改用 UploadStringAsync。 你能帮帮我吗?

最佳答案
尝试 wc.UploadStringAsync(new Uri("http://localhost:80/createpoi"), "POST", parameters) 并记住对您的参数进行 urlencode
