由 五迷三道 提交于 2019-12-23 18:15:00
问题 What is the simplest way to define a custom mapping of a JSON property to a particular object property in RetroFit? Example JSON response for a set of "rewards": [ { "name" : "$5 Voucher", "description" : "Get $5 off your next purchase", "assets" : { "icon" : "icon.png" } } ] Reward class in my Android project: public class Reward { @SerializedName("name") private String name; @SerializedName("description") private String description; @SerializedName("icon") private String icon; } Because

Feign源码学习

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> feign介绍 Feign是一款java的Restful客户端组件，Feign使得 Java HTTP 客户端编写更方便。Feign 灵感来源于Retrofit, JAXRS-2.0和WebSocket。feign在github上有近3K个star，是一款相当优秀的开源组件，虽然相比Retrofit的近30K个star，逊色了太多，但是spring cloud集成了feign，使得feign在java生态中比Retrofit使用的更加广泛。 feign的基本原理是在接口方法上加注解，定义rest请求，构造出接口的动态代理对象，然后通过调用接口方法就可以发送http请求，并且自动解析http响应为方法返回值，极大的简化了客户端调用rest api的代码。官网的示例如下： interface GitHub { @RequestLine("GET /repos/{owner}/{repo}/contributors") List<Contributor> contributors(@Param("owner") String owner, @Param("repo") String repo); } static class Contributor { String login; int contributions;

Android Retrofit - POST request doesn't work, but in Postman it works

由 天大地大妈咪最大 提交于 2019-12-23 16:40:32
问题 This is the error I'm getting: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $ JSON response I'm getting from Postman: { "title": "test title", "body": "test body", "userId": 1, "id": 101 } This is how I echoed the response from the rest API (used slim2 framework): $app->post('/posts', function() use($app){ $res = array( "title" => $app->request->post('title'), "body" => $app->request->post('body'), "userId"

NetworkOnMainThreadException with retrofit-beta2 and rxjava

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-23 15:48:36
问题 I recently upgraded from retroft-beta1 and this was working. I have the following interface for the API: public interface Service { @POST("path") Observable<Object> service(); } And the following call: service.service() .observeOn(AndroidSchedulers.mainThread()) .subscribe(); And it throws a NetworkOnMainThreadException. But this was working in retrofit-beta1. 回答1: From retrofit-beta2, calls to Observable methods now behave synchronously. So subscribeOn must be used: service.service()

Retrofit 2.0: getting response code 200 but not getting the desired data

由 旧城冷巷雨未停 提交于 2019-12-23 12:50:37
问题 A very disappointing feature of Retrofit 2.0 is that it does not exactly tell where it fails in parsing the response. Hence, In postman when I hit the request with same body, I get a login response as: { "result": "success", "response_code": 200, "data": { "id": "1", "display_name": "admin", "email": "payal@teckmovers.com", "username": "admin", "access_token": "8daa8e02ca432e51ae90912fbf63eeea" } } But when I hit the exact same request with exactly the same body in Retrofit, I get a very

Retrofit @Body showing up as parameter in HTTP request

由 有些话、适合烂在心里 提交于 2019-12-23 11:00:50
问题 I've previously used Square's Retrofit successfully for a @GET web API call but when trying to send JSON as the @BODY in a @POST call, on the server (Rails) the JSON is showing up as Parameters rather than the body request. My understanding is that @BODY will add that method parameter to the request in the body. Any idea what I'm doing wrong? WebApi : @POST("/api/v1/gear/scans.json") Response postScans( @Header(HEADER_AUTH) String token, @Body JsonObject scans ); Make web request: RestAdapter
