Question

我的 buid.gradle 就是这样。

implementation 'com.squareup.retrofit2:retrofit:2.3.0'
implementation 'com.squareup.retrofit2:converter-gson:2.3.0'

implementation 'com.squareup.okhttp3:logging-interceptor:3.8.0'
implementation 'com.android.support:design:29.0.2'
implementation 'com.github.bumptech.glide:glide:3.7.0'

生成 Api客户端

public class ApiClient {

    private static Retrofit retrofit = null;

    public static RestApiMethods getRestApiMethods() {
        return createRetrofit().create(RestApiMethods.class);
    }

    private static Retrofit createRetrofit() {
        if (retrofit == null) {
            OkHttpClient.Builder httpClient = getBuilder();
            httpClient.protocols(Arrays.asList(Protocol.HTTP_1_1));
            retrofit = new Retrofit.Builder()
                    .baseUrl(BuildConfig.BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .client(httpClient.build())
                    .build();
        }
        return retrofit;
    }

    @NonNull
    private static OkHttpClient.Builder getBuilder() {
        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        // set your desired log level
        if (BuildConfig.IS_DEBUG)
            logging.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
        httpClient.connectTimeout((long)60 * 3, TimeUnit.SECONDS)
                .readTimeout((long)60 * 3, TimeUnit.SECONDS)
                .writeTimeout((long)60 * 3, TimeUnit.SECONDS);
        // add logging as last interceptor
        httpClient.addInterceptor(logging);
        return httpClient;
    }


}

打来的电话

@GET("URL")
Call<ResponseClass> getUser(@Path("id") int id);

调用API时，获得注释错误。如何使网址类似URL / id？= 1。

Answer 1

尝试这样

 @GET("URL")
Call<ResponseClass> getUser(@Query("id") int id);

Answer 2

您可以使用@Query批注向您的API调用添加参数

@GET("URL")
Call<ResponseClass> getUser(@Query("id") int id);

它将生成如下网址：URL?id=your_id

Answer 3

在您的界面更新getUser()方法中，并添加@Query代替@Path

@GET("URL")
Call<ResponseClass> getUser(@Query("id") int id);

如果是POST请求，并且您想发送FormUrlEncoded值，请使用此代码

@FormUrlEncoded
@POST("URL")
Call<ResponseClass> getUser(@Field("id") int id);

如何在Retrofit GET API中传递查询参数？
