First of all: cookie is not the same as a header. Cookie is a special HTTP header named Cookie followed by list of the pairs of keys and values (separated by “;”). Something like: Cookie: sessionid=sessionid; token=token Since you cannot set multiple Cookie headers in the same request you are not able to use two … Read more
The definition of GET as explained here in this answer explains that a body isn’t supposed to mean anything, so Retrofit doesn’t allow you to add a body. That said, it is not true that a server HAS to follow this format. It’s entirely possible for a server to have a GET endpoint that not … Read more
From source (New URL resolving concept) you can simply specify whole path in post request. Moreover we also can declare a full URL in @Post in Retrofit 2.0: public interface APIService { @POST(“http://api.nuuneoi.com/special/user/list”) Call<Users> loadSpecialUsers(); } Base URL will be ignored for this case.
this is how i do it with extension function and a class fun<T> Call<T>.enqueue(callback: CallBackKt<T>.() -> Unit) { val callBackKt = CallBackKt<T>() callback.invoke(callBackKt) this.enqueue(callBackKt) } class CallBackKt<T>: Callback<T> { var onResponse: ((Response<T>) -> Unit)? = null var onFailure: ((t: Throwable?) -> Unit)? = null override fun onFailure(call: Call<T>, t: Throwable) { onFailure?.invoke(t) } override fun … Read more
I using this to add post parameter to the existing ones. OkHttpClient client = new OkHttpClient.Builder() .protocols(protocols) .addInterceptor(new Interceptor() { @Override public Response intercept(Chain chain) throws IOException { Request request = chain.request(); Request.Builder requestBuilder = request.newBuilder(); RequestBody formBody = new FormEncodingBuilder() .add(“email”, “Jurassic@Park.com”) .add(“tel”, “90301171XX”) .build(); String postBodyString = Utils.bodyToString(request.body()); postBodyString += ((postBodyString.length() > 0) … Read more
@Body – Sends Java objects as request body. @Field – send data as form-urlencoded. This requires a @FormUrlEncoded annotation attached with the method. The @Field parameter works only with a POST. @Field requires a mandatory parameter. In cases when @Field is optional, we can use @Query instead and pass a null value.
Try this code: @Override public void failure(RetrofitError error) { String json = new String(((TypedByteArray)error.getResponse().getBody()).getBytes()); Log.v(“failure”, json.toString()); } with Retrofit 2.0 @Override public void onFailure(Call<Example> call, Throwable t) { String message = t.getMessage(); Log.d(“failure”, message); }
@FieldMap and @Query params both support optional fields. As you mentioned, simply pass null if you don’t want to pass a value.
I would suggest using http://www.jsonschema2pojo.org. You can paste your JSON and it will generate the POJOs for you. That should do the trick.
Here is a working example of an adapter, which automatically wraps a response to the Result wrapper. A GitHub sample is also available. // build.gradle … dependencies { implementation ‘com.squareup.retrofit2:retrofit:2.6.1’ implementation ‘com.squareup.retrofit2:converter-gson:2.6.1’ implementation ‘com.google.code.gson:gson:2.8.5’ } // test.kt … sealed class Result<out T> { data class Success<T>(val data: T?) : Result<T>() data class Failure(val statusCode: Int?) … Read more
