BaaS提供商LeanCloud提供了Restful API，没有提供Retrofit使用教程。

注册API设计：

curl -X POST \
  -H "X-LC-Id: y0crQpaNCKUq9WFaSMLByoKo-gzGzoHsz" \
  -H "X-LC-Key: ihdOweBmtk9yrDbuPEbJfyBb" \
  -H "Content-Type: application/json" \
  -d '{"username":"hjiang","password":"f32@ds*@&dsa","phone":"18612340000"}' \

登录API设计：

curl -X POST \
-H "Content-Type: application/json" \
-H "X-LC-Id: y0crQpaNCKUq9WFaSMLByoKo-gzGzoHsz" \

Retrofit接口：

public interface LeanCloudRetrofitService {

    @POST("users")
    Call<Object> signUp(@Header("X-LC-Id") String appId,
                        @Header("X-LC-Key") String appKey,
                        @Header("Content-Type") String contentType,
                        @Body RequestBody userinfo);

    @POST("login")
    Call<Object> signIn(@Header("X-LC-Id") String appId,
                        @Header("X-LC-Key") String appKey,
                        @Header("Content-Type") String contentType,
                        @Body RequestBody userinfo);
}
