Error Code 415 with retrofit

Question

I have created following API class to query the web service

 @POST("/v1/User/forgot-password")
    @FormUrlEncoded
    fun forgotPass(@Field("email") email: String): Call<ForgotPassword>

and called it as

 val call = RetrofitHelper.instance!!.api.forgotPass(email)
        call.enqueue(object : Callback<ForgotPassword> {

            override fun onResponse(call: Call<ForgotPassword>, response: Response<ForgotPassword>) {
                if (response.code() == 200) {
                    Log.e("response", response.body().toString())
                    forgotPassView.forgotPassRequestSuccess()

                }
            }

            override fun onFailure(call: Call<ForgotPassword>, t: Throwable) {
                Log.e("onFailure", t.message)
            }
        })

The response I am getting is 415, while web services are working fine.

I have tried different techniques to resolve it but it seems there are something more to it. Please help me solve this issue. Thanks.

Should be `"v1/User/forgot-password"` and `baseUrl("blahblah/")` with emphasis on that `/` missing from the first, and there on the second — EpicPandaForce, Apr 27 '18 at 14:11
A 415 usually means you are sending your data in the wrong format. Are you sure the service is expecting the data as `application/x-www-form-urlencoded` vs some other format (JSON, query parameter in the url, etc)? — iagreen, Apr 27 '18 at 16:08
But I am still getting 400 `HttpLoggingInterceptor` doesnt show anything — Ahmed S. Durrani, Apr 28 '18 at 01:38
So your api is expecting something like `{ email : "me@email.com" }` as the POST body? — iagreen, Apr 28 '18 at 01:39

To send a json payload, define a wrapper class --

data class EmailBody(val email: String)

and use that as the @Body for your POST

@POST("v1/User/forgot-password")
fun forgotPass(@Body email: EmailBody): Call<Void>

Then, when you want to call it, wrap the email address in an EmailBody object --

service.forgotPass(EmailBody(email))

things moved, but now I am getting onFailure – Ahmed S. Durrani Apr 28 '18 at 01:53
`End of input at line 1 column 1 path $` – Ahmed S. Durrani Apr 28 '18 at 01:56
What is the server sending back? It sounds like it is sending back nothing at all. From your code above it looks like you are expecting an object back? – iagreen Apr 28 '18 at 01:57
the server will returns nothing. just code 200 or other – Ahmed S. Durrani Apr 28 '18 at 01:58
Ah, then you shouldn't be trying to parse the body as `ForgotPassword`. Use `Void` instead. See the edit above. – iagreen Apr 28 '18 at 01:59
Worked! Perfectly! Thanks! – Ahmed S. Durrani Apr 28 '18 at 02:02
