NSwag - How to read response content in “ProcessResponse”-method












0














I am generating my RestClient via NSwag. When doing an API request in my App, the response content is being read correctly by the generated code:



...
ProcessResponse(client_, response_);

var status_ = ((int)response_.StatusCode).ToString();
if (status_ == "200") {
var responseData_ = response_.Content == null ? null : await response_.Content.ReadAsStringAsync().ConfigureAwait(false);

...


However, sometimes I want to analyze the response and act differently before deserializing the content into JSON. I created another file and implemented the partial method:



partial void ProcessResponse(System.Net.Http.HttpClient client, System.Net.Http.HttpResponseMessage response)


When I try to read the response content inside the "ProcessResponse"-method the same way it is read in the generated class,



await response_.Content.ReadAsStringAsync().ConfigureAwait(false)


my app hangs indefinitely. As "ProcessResponse"-method is not async, I wrapped the call into



var contentString = Task.Run(async () => await response.Content.ReadAsStringAsync()).Result;


When trying to read the result of the task, the app hangs forever. Currently I'm totally at loss:




  1. Why does "ReadAsStringAsync" work in the generated code, but not inside the "ProcessResponse"-method.

  2. How can I read the response content inside the "ProcessResponse"-method?


Thank you very much in advance,
Hendryk
