使用http party将json发送到Web API

Question

I am using http party gem to try and send some json to a web api I have running in Visual Studio.

The C# implementation of my Post API is as below:

 public string GetInfo([FromBody]MyClass[] postedValues)
 {
   //do stuff

If I configure fiddler to hit the method and within fiddler set the request header to be:

Content-Type: application/json; charset=utf-8

and then the request body to be:

[{"Id" : "1", "A" : "1", "B" : "1", "c" : "1"}, {"Id" : "2", "A" : "2", "B" : "2", "C" : "2"}]

when I hit execute the postedValues automatically maps the values from the json into the array - so for the above there will be 2 elements in the array - the Id in MyClass postedValues[0] will be 1 and the Id in postedValues[1] will be 2 and the same for all the other properties.

I want to hit the WebAPi from Ruby on Rails so I am using http party and building the request as below(note full http:// taken out of URL):

post('localhost/api/MyController/GetInfo', :body => [{:Id => '1',
                                                     :A => '1',
                                                     :B => '1',
                                                     :C => '1'}].to_json,
                         :headers => {'Content-Type' => 'application/json'})

However now if I put a breakpoint in my C# method postedValues is null. If I change the C# method to:

public string GetInfo([FromBody]dynamic postedValues)
{
       //do stuff

and run the Ruby code I do see values passed but would much prefer if the values were mapped automatically as they are when I hit it from Fiddler - is there something I am doing incorrect with http party?

Answer 1

I ended up pulling the request body out into a class level variable and it worked mapping the values as expected - hopefully this is useful to someone else.

  @request_body = [{:Id => '1',
                    :A => '1',
                    :B => '1',
                    :C=> '1'}]

    post('localhost:50544/api/MyController/GetInfo', :body => @request_body.to_json,
                                     :headers => {'Content-Type' => 'application/json'})
