Problems Sending FormUrlEncoded using Retrofit

Question

I have this request and I need to send it by FormUrlEncoded using Retrofit

{
   "clnt_id": "OQW",
   "clnt_res": "AA!@#$T",
   "type": "SCDS",
   "len": "ASD"
}

I used this code:

    @FormUrlEncoded
    @POST("Endpoint")
    @Headers("Accept: Application/JSON")
    fun connect(
        @Field("clnt_id") clnt_id: String,
        @Field(value = "clnt_res", encoded = false) clnt_res: String,
        @Field("type") type: String,
        @Field("len") len: String
    ): Observable<Token>

First, thing is that the request is not sent as JSON

Second, the value of "clnt_res", encoded by retrofit

The error log which gets it from retrofit or android crash log — Archu Mohan, Nov 12 '19 at 09:42
Try to send request with `Postman`. If everything is correct then try with retrofit. — Bek, Nov 12 '19 at 09:48

You have 2 options to send json request from android using Retrofit.

Create Pojo Model of json request and pass it by setting values of it.
Create HashMap and pass it to request.

Here is solution using 2nd Method:

Create hashmap and put key(parameters) and value:

Map<String,String> requestMap = new HashMap<>();
        requestMap.put("clnt_id","your_value");
        requestMap.put("clnt_res","your_value");
        requestMap.put("type","your_value");
        requestMap.put("len","your_value");

Then pass it to your retrofit request using FieldMap:

@FormUrlEncoded
    @POST("Endpoint")
    @Headers("Accept: Application/JSON")
    fun connect(
        @FieldMap requestMap:Map<String,String>
    ): Observable<Token>

I finally get the answer and it was a problem with symbol '$' in 'clnt_res' value "AA!@#$T", The problem is in kotlin to escape a special char you need to do this "\$", what I made the IDE didn't tell me that it is wrong is this "$/".

Still not Resolved in Java, I am coping value from a TextView. If anyone enters '@' character, it gets converted to '%40' – SAM Aug 18 '21 at 12:00
