我正在使用改装2.1，当我打电话给@GET时，它说
HTTP method annotation is required (e.g., @GET, @POST, etc.).
现在..如果我定义@ retrofit.http.GET它会抛出
No Retrofit annotation found. (parameter #1)
使用@POST可以，它可以使用！
这是HTTP方法的错误日志...

@POST带注释的方法，必须有参数，标记为@Body
例如：
@POST("/user/mobile/verify")
VerifyCodeResponse verifyMobile(@Body VerifyRequest request);

首先，请检查所有使用Retrofit的条款中的导入。
在您的界面Testapi中，您使用了retrofit2，但在您的方法getjson（）中，您正在创建retrofit.RestAdapter而不是retrofit2.Retrofit，这绝对是错误的。
请解决此问题并检查它是否有效。
PS。以下是关于从reftrofit 1. *到2. *的迁移的非常好的教程。跟随他们，一切都应该正常工作：

为什么不直接从maven使用retrofit2 gradle依赖项？ - 例如在附加链接中。
