C ＃ use restsharp library to realize post request

Last temporary use Python send out POST request , Get the required information from the specified website . I thought Python Handy , The supported libraries are also familiar , Just use 3 Minutes will this POST The requested function is written , Also packed into exe file , stay C# Application calls , And can normally obtain the required information , The problem is solved , But I received many enthusiastic friends , Put forward a question ,C# It can be realized by itself POST request , There are also many practical libraries that can be used , Why do you toss about so much ！

In daily work and life , I think the first thing is to solve the problem , No matter what way I use , First of all, implement the required functions , The second is to pursue efficiency and the complexity of solving problems . today , Used RestSharp The library tested , It's OK, too . However, this library has made important adjustments , Some changes have taken place in the way of use .

RestSharp The request body can be serialized into JSON or XML And deserialize the response . It can also be based on different parameter types （ route 、 Inquire about 、 Form or body ） Form a valid request URI.RestSharp The latest version of is v107. This is a major upgrade , It contains quite a few major changes . The most important change is RestSharp Stop using legacy HttpWebRequest class , Instead, use the well-known “HttpClient”. This measure has solved many problems , For example, due to incorrect HttpClient The instance cache causes the connection to hang 、 Updated protocol support and many other issues . Another major change is SimpleJson Retire completely from the code base . contrary ,RestSharp Use JsonSerializer In bag System.Text.Json, This is a ASP.NET Core Default serializer for .

        var request = new RestRequest();

        request.Method = Method.Post;

        request.Timeout = 5000;

        request.AddParameter(contentType, content, ParameterType.RequestBody);

        var response = client.Execute(request);

        return response.Content;

        request.Timeout = 5000;

        request.AddHeader("content-type", "text/html; charset=utf-8");

        request.AddHeader("content-encoding", "gzip");

        var response = client.Execute(request);

        return response.Content;

    }

    catch (Exception ex)

    {

        return ex.ToString();

    }

}

test OK, And call Python The result achieved by our application is the same ！
