初始化Retrofit
String BASE_URL = "http://102.10.10.132/api/";
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.build();
GET
樣式1(一個簡單的get請求)
http://102.10.10.132/api/News
@GET("News")
Call<NewsBean> getItem();
樣式2(URL中有參數)
http://102.10.10.132/api/News/1
http://102.10.10.132/api/News/{資訊id}
@GET("News/{newsId}")
Call<NewsBean> getItem(@Path("newsId") String newsId);
或
http://102.10.10.132/api/News/1/類型1
http://102.10.10.132/api/News/{資訊id}/{類型}
@GET("News/{newsId}/{type}")
Call<NewsBean> getItem(@Path("newsId") String newsId, @Path("type") String type);
樣式3(參數在URL問号之後)
http://102.10.10.132/api/News?newsId=1
http://102.10.10.132/api/News?newsId={資訊id}
@GET("News")
Call<NewsBean> getItem(@Query("newsId") String newsId);
或
http://102.10.10.132/api/News?newsId=1&type=類型1
http://102.10.10.132/api/News?newsId={資訊id}&type={類型}
@GET("News")
Call<NewsBean> getItem(@Query("newsId") String newsId, @Query("type") String type);
樣式4(多個參數在URL問号之後,且個數不确定)
http://102.10.10.132/api/News?newsId=1&type=類型1...
http://102.10.10.132/api/News?newsId={資訊id}&type={類型}...
@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
樣式1(需要補全URL,post的資料隻有一條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);
樣式2(需要補全URL,問号後加入access_token,post的資料隻有一條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);
樣式3(需要補全URL,問号後加入access_token,post一個body(對象))
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
樣式1(需要補全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);
樣式2(需要補全URL,問号後加入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);
樣式3(帶有body)
http://102.10.10.132/api/Comments
@HTTP(method = "DELETE",path = "Comments",hasBody = true)
Call<ResponseBody> deleteCommont(
@Body CommentBody body
);
CommentBody
:需要送出的内容,與
Post
中的
Body
相同
PUT(這個請求很少用到,例子就寫一個)
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);
總結
@Path:所有在網址中的參數(URL的問号前面),如:
http://102.10.10.132/api/Accounts/{accountId}
@Query:URL問号後面的參數,如:
http://102.10.10.132/api/Comments?access_token={access_token}
@QueryMap:相當于多個@Query
@Field:用于POST請求,送出單個資料
@Body:相當于多個@Field,以對象的形式送出
Tips
-
Tips1
使用@Field時記得添加@FormUrlEncoded
-
Tips2
若需要重新定義接口位址,可以使用@Url,将位址以參數的形式傳入即可。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);
