初始化Retrofit
String BASE_URL = "http://102.10.10.132/api/";
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.build();
GET
样式1(一个简单的get请求)
@GET("News")
Call<NewsBean> getItem();
样式2(URL中有参数)
http://102.10.10.132/api/News/1
http://102.10.10.132/api/News/{资讯id}
@GET("News/{newsId}")
Call<NewsBean> getItem(@Path("newsId") String newsId);
或
http://102.10.10.132/api/News/1/类型1
http://102.10.10.132/api/News/{资讯id}/{类型}
@GET("News/{newsId}/{type}")
Call<NewsBean> getItem(@Path("newsId") String newsId, @Path("type") String type);
样式3(参数在URL问号之后)
http://102.10.10.132/api/News?newsId=1
http://102.10.10.132/api/News?newsId={资讯id}
@GET("News")
Call<NewsBean> getItem(@Query("newsId") String newsId);
或
http://102.10.10.132/api/News?newsId=1&type=类型1
http://102.10.10.132/api/News?newsId={资讯id}&type={类型}
@GET("News")
Call<NewsBean> getItem(@Query("newsId") String newsId, @Query("type") String type);
样式4(多个参数在URL问号之后,且个数不确定)
http://102.10.10.132/api/News?newsId=1&type=类型1...
http://102.10.10.132/api/News?newsId={资讯id}&type={类型}...
@GET("News")
Call<NewsBean> getItem(@QueryMap Map<String, String> map);
也可以
@GET("News")
Call<NewsBean> getItem(
@Query("newsId") String newsId,
@QueryMap Map<String, String> map);
POST
样式1(需要补全URL,post的数据只有一条reason)
http://102.10.10.132/api/Comments/1
http://102.10.10.132/api/Comments/{newsId}
@FormUrlEncoded
@POST("Comments/{newsId}")
Call<Comment> reportComment(
@Path("newsId") String commentId,
@Field("reason") String reason);
样式2(需要补全URL,问号后加入access_token,post的数据只有一条reason)
http://102.10.10.132/api/Comments/1?access_token=1234123
http://102.10.10.132/api/Comments/{newsId}?access_token={access_token}
@FormUrlEncoded
@POST("Comments/{newsId}")
Call<Comment> reportComment(
@Path("newsId") String commentId,
@Query("access_token") String access_token,
@Field("reason") String reason);
样式3(需要补全URL,问号后加入access_token,post一个body(对象))
http://102.10.10.132/api/Comments/1?access_token=1234123
http://102.10.10.132/api/Comments/{newsId}?access_token={access_token}
@POST("Comments/{newsId}")
Call<Comment> reportComment(
@Path("newsId") String commentId,
@Query("access_token") String access_token,
@Body CommentBean bean);
DELETE
样式1(需要补全URL)
http://102.10.10.132/api/Comments/1
http://102.10.10.132/api/Comments/{commentId}
@DELETE("Comments/{commentId}")
Call<ResponseBody> deleteNewsCommentFromAccount(
@Path("commentId") String commentId);
样式2(需要补全URL,问号后加入access_token)
http://102.10.10.132/api/Comments/1?access_token=1234123
http://102.10.10.132/api/Comments/{commentId}?access_token={access_token}
@DELETE("Comments/{commentId}")
Call<ResponseBody> deleteNewsCommentFromAccount(
@Path("commentId") String commentId,
@Query("access_token") String access_token);
样式3(带有body)
http://102.10.10.132/api/Comments
@HTTP(method = "DELETE",path = "Comments",hasBody = true)
Call<ResponseBody> deleteCommont(
@Body CommentBody body
);
CommentBody
:需要提交的内容,与Post
中的Body
相同
PUT(这个请求很少用到,例子就写一个)
http://102.10.10.132/api/Accounts/1
http://102.10.10.132/api/Accounts/{accountId}
@PUT("Accounts/{accountId}")
Call<ExtrasBean> updateExtras(
@Path("accountId") String accountId,
@Query("access_token") String access_token,
@Body ExtrasBean bean);
总结
@Path:所有在网址中的参数(URL的问号前面),如:
http://102.10.10.132/api/Accounts/{accountId}
@Query:URL问号后面的参数,如:
http://102.10.10.132/api/Comments?access_token={access_token}
@QueryMap:相当于多个@Query
@Field:用于POST请求,提交单个数据
@Body:相当于多个@Field,以对象的形式提交
Tips
- Tips1
使用@Field时记得添加@FormUrlEncoded - Tips2
若需要重新定义接口地址,可以使用@Url,将地址以参数的形式传入即可。如
@GET
Call<List<Activity>> getActivityList(
@Url String url,
@QueryMap Map<String, String> map);
Call<List<Activity>> call = service.getActivityList(
"http://115.159.198.162:3001/api/ActivitySubjects", map);
