Failed to connect to the remote server (web service)

Question

I tried to integrate this web service into my asp.net project, but it is causing such an error! If you have any ideas on this, try me. There are very rare materials about oodle web services and the oodle API.

Answer 1

It is simply not a SOAP web service. This is a REST XML service. REST services do not provide self-describing metadata in the form of WSDL.

You need another way to communicate with the service. If there is no C # shell, you probably have to write a url generator yourself, and the .NET Framework will deserialize the xml documents for you into beautifully written classes (which you also write yourself).

EDIT: Also, if you are loading an XML document from a web application, you need to consider a few things.

When you are developing, make sure that you are using Visual Studio as an Administrator .

When deploying to a hosting provider, make sure that you do not use Medium Trust , as this may prevent you from accessing external web sources.

But still I cannot understand why the Add Web Directory dialog cannot connect to the oodle web server. Check network settings, firewall settings, etc. If you can visit the URL in your web browser, you can download the document via code.

Answer 2

try { string url = @"http://api.oodle.com/api/v2/listings?key=TEST&region=chicago"; WebClient webClient = new WebClient(); webClient.Encoding = Encoding.UTF8; string result = webClient.DownloadString(url); } catch (Exception ex) { Response.Write(ex.ToString()); } 

This statement throws an exception.

  string result = webClient.DownloadString(url); 

and exception information -
