改装收到400个错误请求,但与邮递员一起工作

首先,你的api是一个GET方法,所以用@GET代替@POST

第二,在改造中尝试更改url基url .baseUrl(“ https://locodealapi.herokuapp.com ") 到baseUrl(“ https://locodealapi.herokuapp.com/ ") 这会奏效的。或者把你的问题留下评论 2.这是示例代码

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient okHttpClient = new OkHttpClient.Builder().addInterceptor(
            new Interceptor() {
                @Override
                public Response intercept(Chain chain) throws IOException{
                 Request original = chain.request();
                    // Request customization: add request headers
                    Request.Builder requestBuilder =original.newBuilder().
                            method(original.method(), original.body());
                    Request request = requestBuilder.build();
                    return chain.proceed(request);
                }
            })
            .addInterceptor(interceptor).connectTimeout(60,TimeUnit.SECONDS).readTimeout(60, TimeUnit.SECONDS).build();

    Retrofit retrofit = new Retrofit.Builder().baseUrl("https://locodealapi.herokuapp.com/")
            .addConverterFactory(GsonConverterFactory.create())
            .client(okHttpClient).build();
    UserApi userApi = retrofit.create(UserApi.class);
    Call<ResponseBody> call = userApi.deals("your token");
    call.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call,retrofit2.Response<ResponseBody> response) {
        }
        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {}
    });
}

@GET(“api/deals”) 呼叫交易(@Header(“x-access-token”)字符串x\u access\u token);

今天的问候!

试试这个:

@FormUrlEncoded
@POST("/api/deals")
    Call<ResponseBody> deals(@Header("x-access-token") String x_access_token, @Field("<parameter_name>") String parameter);

调用api如下:

 Call<ResponseBody> call = client.deals(token,"<parameter>");

在这里,我假设API有一个参数,可以作为方法deals()中的第二个参数传递。可以传递多个参数作为方法的参数。

我希望这能解决你的问题。如果没有,请提供您想要调用的API的完整详细信息。

A. 400 response 这意味着您的请求和服务器之间存在分歧,但请求是创建、发送和解析的。这意味着 Retrofit 工作正常。您可以使用OkHttp的日志拦截器来记录原始请求,并将其与服务器期望的进行比较。

也是你的 Response 大小约为 5.96 MB . 这是太大的反应。您可以实现分页或类似的方法来分解数据,而不是在单个响应中接收这么多数据。这可能是原因之一。

//Your Main connection Class

public class ApiClient {
public static final int DEFAULT_TIMEOUT_SEC = 90;
public static OkHttpClient client;
private static Retrofit retrofit = null;

public static Retrofit getClient() {

    OkHttpClient.Builder httpClient = new OkHttpClient.Builder()
            .connectTimeout(DEFAULT_TIMEOUT_SEC, TimeUnit.SECONDS)
            .readTimeout(DEFAULT_TIMEOUT_SEC, TimeUnit.SECONDS)
            .writeTimeout(DEFAULT_TIMEOUT_SEC, TimeUnit.SECONDS);

    httpClient.addInterceptor(new Interceptor() {
        @Override
        public Response intercept(Interceptor.Chain chain) throws IOException {
            Request original = chain.request();
            System.out.println("API_KEY"+PrefManager.getActiveInstance(RecrouteCandidateApplication.getsCurrentContext()).getDeviceToken());
            Request request = original.newBuilder()
                    .header("x-access-token",YOUR_ACCESS_TOKEN"")
                    .method(original.method(), original.body())
                    .build();

            return chain.proceed(request);
        }
    });

   //For logging the call on Logcat
    HttpLoggingInterceptor interceptor1 = new HttpLoggingInterceptor();
    interceptor1.setLevel(HttpLoggingInterceptor.Level.BODY);
    httpClient.addInterceptor(interceptor1);
    client = httpClient.build();

    if (retrofit == null) {
        retrofit = new Retrofit.Builder()
                .baseUrl(AppConstants.BASE_URL)
                .client(client)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
    }
    return retrofit;
}

在你的类中使用,它将启动这样的连接

ApiInterface apiService =
                ApiClient.getClient().create(ApiInterface.class);

这将是你的ApiInterface

public interface ApiInterface {

@POST("Your url here")
Call<JsonObject> sampleMethod();
/*For non-empty body use this*/
//Call<JsonObject> getSignUpResponse(@Body JsonObject register);

//For form data use this
@FormUrlEncoded
@POST("Your url here")
Call<String> sampleMethod1(@Field(value= "param1_key", encoded = true) String param1_value);

 }

像这样调用json

JsonObject obj= new JsonObject();
obj.addProperty("key1","keyvalue");

Call<JsonObject> call = apiService.sample1(obj);
                            call.enqueue(new Callback<JsonObject>() {
                                @Override
                                public void onResponse(Call<JsonObject> call, Response<JsonObject> response) {
                                    if (response.body().get("status").getAsString().equals("1")) {
                                        Toast.makeText(context, response.body().get("msg").getAsString(), Toast.LENGTH_LONG).show();
                                    } else {
                                        Toast.makeText(context, response.body().get("msg").getAsString(), Toast.LENGTH_LONG).show();
                                    }
                                }

                                @Override
                                public void onFailure(Call<JsonObject> call, Throwable t) {
                                    Toast.makeText(context, AppConstants.NO_DATA_AVAILABLE, Toast.LENGTH_LONG).show();
                                }
                            });

对我来说,问题是因为我在Gson builder中有一行:

 .excludeFieldsWithoutExposeAnnotation()

使用上述行,如果模型类中未使用 @Exposed 注释。 正在删除 .excludeFieldsWithoutExposeAnnotation() 帮我解决了这个问题。
