Retrofit 2 - URL Query Parameter
提问by Alan
I am using a query parameters to set the values needed by the Google Maps API.
我正在使用查询参数来设置 Google Maps API 所需的值。
The issue is I do not need the &sign for the first query parameter.
问题是我不需要&第一个查询参数的符号。
@GET("/maps/api/geocode/json?")
Call<JsonObject> getLocationInfo(@Query("address") String zipCode,
@Query("sensor") boolean sensor,
@Query("client") String client,
@Query("signature") String signature);
Retrofit generates:
改造产生：
&address=90210&sensor=false&client=gme-client&signature=signkey
which causes the call the fail when I need it to be
当我需要它时，这会导致调用失败
address=90210&sensor=false&client=gme-client&signature=signkey
How do I fix this?
我该如何解决？

If you specify @GET("foobar?a=5"), then any @Query("b")must be appended using &, producing something like foobar?a=5&b=7.
如果您指定@GET("foobar?a=5")，则 any@Query("b")必须附加 using &，产生类似foobar?a=5&b=7.
If you specify @GET("foobar"), then the first @Querymust be appended using ?, producing something like foobar?b=7.
如果您指定@GET("foobar")，则第一个@Query必须附加 using ?，产生类似foobar?b=7.
That's how Retrofit works.
这就是改造的工作原理。
When you specify @GET("foobar?"), Retrofit thinks you already gave some query parameter, and appends morequery parameters using &.
当您指定 时@GET("foobar?")，Retrofit 认为您已经提供了一些查询参数，并使用 附加了更多查询参数&。
Remove the ?, and you will get the desired result.
删除?，您将获得所需的结果。

I am new to retrofit and I am enjoying it. So here is a simple way to understand it for those that might want to query with more than one query: The ? and & are automatically added for you.
我是改装的新手，我很喜欢它。因此，对于那些可能想要使用多个查询进行查询的人来说，这是一种理解它的简单方法： ? 和 & 会自动为您添加。
Interface:
界面：
public interface IService {
String BASE_URL = "https://api.test.com/";
String API_KEY = "SFSDF24242353434";
@GET("Search") //i.e https://api.test.com/Search?
Call<Products> getProducts(@Query("one") String one, @Query("two") String two,
@Query("key") String key)
}
It will be called this way. Considering you did the rest of the code already.
它将以这种方式调用。考虑到您已经完成了其余的代码。
Call<Results> call = service.productList("Whatever", "here", IService.API_KEY);
For example when a query is returned, it will look like this.
例如，当返回查询时，它看起来像这样。
//-> https://api.test.com/Search?one=Whatever&two=here&key=SFSDF24242353434

public interface IService {
String BASE_URL = "https://api.demo.com/";
@GET("Login") //i.e https://api.demo.com/Search?
Call<Products> getUserDetails(@Query("email") String emailID, @Query("password") String password)
}
It will be called this way. Considering you did the rest of the code already.
它将以这种方式调用。考虑到您已经完成了其余的代码。
Call<Results> call = service.getUserDetails("[email protected]", "Password@123");
For example when a query is returned, it will look like this.
例如，当返回查询时，它看起来像这样。
https://api.demo.com/[email protected]&password=Password@123
