Method getResources没有用请求类型注释(例如,GET,POST)是什么意思？

Question

private interface ResourcesApi {
        @POST("/synchronize")
        void getResources(@Body Map<String, Map<String, Object>> map,
                          Callback<DataModel> callback);
    }

与调用代码:

mApi.getResources(data, this);

该类实现了Callback,因此定义了成功/失败.

Answer 1

这意味着@POST在运行时无法找到注释.如果没有HTTP方法类型(以及它包含的相对URL),则Retrofit无法发出请求.

您使用Proguard或其他工具来修剪"未使用"的代码吗？如果是这样,请指示它保留Retrofit的注释.

除了Jake的回答,这是我必须添加到我的proguard文件以使其正常工作:

-keep class com.google.gson.** { *; }
-keep class com.google.inject.** { *; }
-keep class org.apache.http.** { *; }
-keep class org.apache.james.mime4j.** { *; }
-keep class javax.inject.** { *; }
-keep class retrofit.** { *; }
