改造2 @path Vs @query [英] retrofit 2 @path Vs @query

问题描述

我是改造2库的新手。我读了几篇文章作为初学者入门，我设法从我的RESTful API中获取XML数据而不指定参数。在我的方法中生成XML资源如下。

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.

 @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;
    }

现在我试图在界面中传递参数

Now when I tried to pass parameter in the interface

@GET("user/{username}/{password}")
Call<List<UserCredentail>> getUserOuth(@Query("username") String username, @Query("password") String password);  

无法运行，客户端未收到任何数据。我花了一个星期试图通过使用非参数调用获取资源来修复它;
因此尝试将其更改为

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

@GET("user/{username}/{password}")
Call<List<UserCredentail>> getUserOuth(@Path("username") String username, @Path("password") String password);  

并且工作正常。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？

and it worked fine. So My question is: When do I need to use @Query and @Path Annotation in retrofit 2 ?

推荐答案

考虑这是网址：

www .app.net / api / searchtypes / 862189 / filters？Type = 6& SearchText = School

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);

所以我们有：

www。 app.net/api/searchtypes/{Path}/filters?Type={Query}&SearchText={Query}

www.app.net/api/searchtypes/{Path}/filters?Type={Query}&SearchText={Query}

？之后的事情通常是查询。​​

Things that come after the ? are usually queries.
