【Android TimeCat】 当RxJava遇到Retrofit(二)api注解@Path, @Url等

背景

下面分为GETPOSTDELETE还有PUT的请求,说明@Path@Query@QueryMap@Body@Field的用法。

初始化Retrofit

String BASE_URL = "http://192.168.88.105:8000/api/";
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.build();

GET

样式1(一个简单的get请求)

http://192.168.88.105:8000/api/News

1
2
@GET("News")
Call<NewsBean> getItem();

样式2(URL中有参数)

http://192.168.88.105:8000/api/News/1
http://192.168.88.105:8000/api/News/{资讯id}

1
2
3

@GET("News/{newsId}")
Call<NewsBean> getItem(@Path("newsId") String newsId);


http://192.168.88.105:8000/api/News/1/类型1
http://192.168.88.105:8000/api/News/{资讯id}/{类型}

1
2
@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://192.168.88.105:8000/api/News?newsId=1
http://192.168.88.105:8000/api/News?newsId={资讯id}

1
2
@GET("News")
Call<NewsBean> getItem(@Query("newsId") String newsId);


http://192.168.88.105:8000/api/News?newsId=1&type=类型1
http://192.168.88.105:8000/api/News?newsId={资讯id}&type={类型}

1
2
@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://192.168.88.105:8000/api/News?newsId=1&type=类型1
http://192.168.88.105:8000/api/News?newsId={资讯id}&type={类型}

1
2
@GET("News")
Call<NewsBean> getItem(@QueryMap Map<String, String> map);

也可以

1
2

4
@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://192.168.88.105:8000/api/Comments/1
http://192.168.88.105:8000/api/Comments/{newsId}

1
2
3
4
5
@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://192.168.88.105:8000/api/Comments/1?access_token=1234123
http://192.168.88.105:8000/api/Comments/{newsId}?access_token={access_token}

1
2

6
@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://192.168.88.105:8000/api/Comments/1?access_token=1234123
http://192.168.88.105:8000/api/Comments/{newsId}?access_token={access_token}

1
2
3
4
5
@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://192.168.88.105:8000/api/Comments/1
http://192.168.88.105:8000/api/Comments/{commentId}

1
2
3
@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://192.168.88.105:8000/api/Comments/1?access_token=1234123
http://192.168.88.105:8000/api/Comments/{commentId}?access_token={access_token}

1
2
3
4
@DELETE("Comments/{commentId}")
Call<ResponseBody> deleteNewsCommentFromAccount(
@Path("commentId") String commentId,
@Query("access_token") String access_token);

样式3(带有body)

http://192.168.88.105:8000/api/Comments

1
2
3
4
5
@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://192.168.88.105:8000/api/Accounts/1
http://192.168.88.105:8000/api/Accounts/{accountId}

1
2
3
4
5
@PUT("Accounts/{accountId}")
Call<ExtrasBean> updateExtras(
@Path("accountId") String accountId,
@Query("access_token") String access_token,
@Body ExtrasBean bean);

总结

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
    1
    2
    3
    4
    5
    6
    @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);
