retrofit 2 @path Vs @query
提问by Mwesigye John Bosco
I am new to retrofit 2 library.I read several articles to get started as a beginner and I managed to fetch XML data from my RESTful API without specifying parameters.In my method that generated the XML resource is below.
我是改造 2 库的新手。我阅读了几篇文章作为初学者入门，我设法从我的 RESTful API 获取 XML 数据而不指定参数。在我生成 XML 资源的方法中，如下所示。
@GET
@Path("/foods")
@Produces(MediaType.APPLICATION_XML)
public List<FoodPyramid> getFoodPyramid() {
Session session = HibernateUtil.getSessionFactory().openSession();
trans = session.beginTransaction();
List<FoodPyramid> foodList = session.createQuery("from FoodPyramid").list();
try {
trans.commit();
session.close();
} catch (Exception e) {
session.close();
System.err.println("Food Pyramid fetch " + e);
}
System.err.println("Am in the food modal. . . . . . . .");
return foodList;
}
Now when I tried to pass parameter in the interface
现在当我尝试在界面中传递参数时
@GET("user/{username}/{password}")
Call<List<UserCredentail>> getUserOuth(@Query("username") String username, @Query("password") String password);
It failed to run,no data was receive by a client . It took me a week trying to fix it though by using a non parameter call fetched the resources; So tried to change it to:
它无法运行，客户端未收到任何数据。我花了一周的时间试图通过使用非参数调用获取资源来修复它；所以尝试将其更改为：
@GET("user/{username}/{password}")
Call<List<UserCredentail>> getUserOuth(@Path("username") String username, @Path("password") String password);
and it worked fine. So My question is: When do I need to use @Queryand @PathAnnotation in retrofit 2?
它工作正常。所以我的问题是：我什么时候需要在改造 2 中使用@Query和@Path注释？

Consider this is the url:
考虑这是网址：
www.app.net/api/searchtypes/862189/filters?Type=6&SearchText=School
www.app.net/api/searchtypes/862189/filters?Type=6&SearchText=School
Now this is the call:
现在这是电话：
@GET("/api/searchtypes/{Id}/filters")
Call<FilterResponse> getFilterList(
@Path("Id") long customerId,
@Query("Type") String responseType,
@Query("SearchText") String searchText
);
So we have:
所以我们有：
www.app.net/api/searchtypes/{Path}/filters?Type={Query}&SearchText={Query}
Things that come after the ?are usually queries.
之后的事情？通常是查询。

Query is use for URL parameters and with @Query("password") the URL should be :
查询用于 URL 参数，使用 @Query("password") 时，URL 应该是：
user/john?password=****
Path is use to replace item defined in your path, like
路径用于替换路径中定义的项目，例如
user/{username}
回答by Nikson Kanti Paul
For example:
例如：
@GET("/user/{username}?type={admin}")
Here usernameis the pathvariable, and typeis the query variable
这里username是path变量，type是查询变量
@GET("/user/{username}?type={admin}")
void getUserOuth(@Path("username") String username, @Query("type") String type)

@Path is used when you have url which has '/' dynamic value after a backword slash.Example "http://google.com/index.html/userid. So in this url /userid is dynamic so to access this url your request should be @Get("index.html/{userid}") Calldata(@Path("userid")int id);
@Path 用于当您的 url 在反向斜杠后具有 '/' 动态值。例如“ http://google.com/index.html/userid。所以在这个 url /userid 是动态的，所以要访问这个 url 你的请求应该是@Get("index.html/{userid}") Calldata(@Path("userid")int id);
@Query is used when you have a url which has '?' dynamic value after a question mark.Example "http://google.com/index.html?userid.Soin this url ? userid is dynamic so to access this url your request should be @Get("index.html") Calldata(@Query("userid")int id);
@Query 当你有一个带有 '?' 的 url 时使用。问号后的动态值。例如“ http://google.com/index.html?userid.So在这个 url 中？userid 是动态的所以访问这个 url 你的请求应该是 @Get("index.html") Calldata (@Query("userid")int id);

@Path annotation use for ordering parameters as your own way. And defined the order in url.
@Path 注释用于按照您自己的方式对参数进行排序。并在 url 中定义了顺序。
@GET("user/{username}/{password}")
Call<List<UserCredentail>> getUserOuth(@Path("username") String username, @Path("password") String password);
@Query annotation auto order of parameters and added with url including "?" symbol.
@Query 注释自动参数顺序并添加了包含“？”的 url 象征。
@GET("user")
Call<List<UserCredentail>> getUserOuth(@Query("username") String username, @Query("password") String password);
回答by Mina
@Query
@Query
- This annotation represents any query key value pair to be sent along with the network request
- 这个注解代表任何与网络请求一起发送的查询键值对
@Path
@Path
- This annotation implies that the passed parameter will be swapped in the endpoint path
- 这个注解意味着传递的参数将在端点路径中交换
