retrofit2

问题 I saw a lot of articles and questions about error handling using retrofit combined with RxAndroid, but i am not able to set my configuration right. What do I want to accomplish: when receiving a 4xx code: handle it on onError() when receiving a 2xx code: -> try to parse to expected response and deliver it onNext() -> If not possible try to convert the JSON answer to MyAPIError class (simple POJO with errorNum and message) and deliver it on onError. So either 2xx or 4xx http codes might end up

问题 I wish to handle all my responses in single method. the purpose is to recall the service when the response code is not 3, when the response code is 3 I intend to first refresh the token and then recall the same service. I've created a Basecallback class to catch one method but I can't see the log and can't catch breakpoints. BASECALLBACK.class public class BaseCallBack<T> implements Callback<T> { @Override public void onResponse(Call<T> call, Response<T> response) { if (!response.isSuccessful

问题 I found this. But in new ver compile 'com.squareup.retrofit2:adapter-rxjava:2.2.0' at CallAdapter it has two params CallAdapter<?,?> How to modify RxCallAdapterWrapper to implement if from CallAdapter<?,?> 回答1: Disclaimer: I'm the author of the blog post you referenced The original post was meant as a proof of concept and for RxJava 2 so it's easier for me to explain with that version too, but I'll try and cover more ground. I'm guessing you're using version 1, since you talk about adapter

问题 I'm posting content to the server in a multipart/form-data request. and the data I'm posting contains multiple parameters including a file array parameter (files[]). Using postman I'm setting the parameters and the files as: first-parameter=text content second-parameter=text content files[0]={first selected file} files[1]={second selected file} Submitting this request on postman is always successful, and the files are uploaded successfully. When I generate code snippets on postman, this is

问题 I'm trying to upload a file to Amazon's S3 using a pre-signed URL. I get the URL from a server which generates the URL & sends it to me as part of a JSON object. I get the URL as a String, something like this: https://com-example-mysite.s3-us-east-1.amazonaws.com/userFolder/ImageName?X-Amz-Security-Token=xxfooxx%2F%2F%2F%2F%2F%2F%2F%2F%2F%2Fxxbarxx%3D&X-Amz-Algorithm=xxAlgoxx&X-Amz-Date=20170831T090152Z&X-Amz-SignedHeaders=host&X-Amz-Expires=3600&X-Amz-Credential=xxcredxx&X-Amz-Signature

问题 The response from retrofit2 may be of the following types.(and we don't know before hand which response will come) { "id": "abc", "place": "LA", "driverId": "abbabaaan" } or { "id": "abc", "place": "LA", "driverId": { "name": "xyz", "id": "jygsdsah", "car": "merc" } } Is there any way to define a class so that while deserializing jackson will check the type of object "driverId" contains and assigns it to say "driverIdObj" field or "driverIdStr" field in the class. 回答1: You could deserialize
