Regarding the presentation code, I would like to obtain the return value by referring to the reference site A, but I can't get .json well, why is this?The client_name parameter is the same as the one you created on the web.
JsonReaderException: Unexpected character encountered while parsing value: <.Path', line 0, position 0.
//Console.WriteLine(res); displays html successfully, but
An exception occurs when trying to display json.

Because html is html and not json, passing html to JsonConvert.DeserializeObject() will almost cause an exception.There may be no exceptions, but you should still not get the result you expect.
You can see it by looking at https://json.org/, but JSON is
{ (indicating object start)[ (representing the beginning of the array)" (indicating the start of a string)0 through 9 (first digit) - (negative sign)t (first letter of true)f (first letter of false)n (first letter of null)Begins with one of the .In response to the exception message
JsonReaderException: Unexpected character encountered while parsing value: <.Path', line 0, position 0.
As mentioned above, JSON cannot parse it because the first character was <.
Needless to say, JsonConvert.DeserializeObject() expects the JSON string to be entered, so try to pass the JSON string.
