GET请求

多个参数在URL问号之后,且个数不确定

http://api.stay4it.com/News?newsId=1&type=类型1… 
http://api.stay4it.com/News?newsId={资讯id}&type={类型}…

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

或者:

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

POST请求

  • 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);
  • 1
  • 2
  • 3
  • 4
  • 5
  • 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);
  • 1
  • 2
  • 3
  • 4
  • 5
  • 6
  • 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

需要补全URL

http://102.10.10.132/api/Comments/1 
http://102.10.10.132/api/Comments/{newsId}

{access_token}

@DELETE("Comments/{commentId}")Call<ResponseBody> deleteNewsCommentFromAccount(        @Path("accountId") String accountId);
  • 1
  • 2
  • 3

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/{newsId}?access_token={access_token}

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

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);
  • 1
  • 2
  • 3
  • 4
  • 5

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

  • Tip1 
    使用@Field时记得添加@FormUrlEncoded
  • Tip2 
    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);
  • 1
  • 2
  • 3
  • 4
Call<List<Activity>> call = service.getActivityList(              "http://115.159.198.162:3001/api/ActivitySubjects", map);

还有@FieldMap

如匿名发表新评论:

接口地址为: /posts/create

HTTP请求方式: POST

请求示例为:

Request URL: http://api.duoshuo.com/posts/create.json 
Request Method: POST 
Post Data: short_name=official&author_email=jp.chenyang%40gmail.com&author_name=Perchouli&thread_id=1152923703638301959&author_url=http%3A%2F%2Fduoshuo.com&message=匿名发表新评论

1.Field方式实现

@FormUrlEncoded@POST("/posts/create.json")Call<CommitResult> createCommit(@Field("secret") String secret,                   @Field("short_name") String shortName,                   @Field("author_email") String authorEmail,                   @Field("author_name") String authorName,                   @Field("thread_key") String threadKey,                   @Field("author_url") String author_url,                   @Field("message") String message);

2.Field Map实现方式

@FormUrlEncoded@POST("/posts/create.json")Call<CommitResult> createCommit(@FieldMap Map<String, String> map);
