改造 400 错误请求 [英] retrofit 400 Bad Request

问题描述

这是我用于网络调用的函数.

This is the function which i used for the network calls.

private void getSample() {


    Log.d("", "getSample : ");
    OkHttpClient client = new OkHttpClient();

    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    client.interceptors().add(interceptor);

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(NetworkCalls.BASE_URL)
            .client(client)

            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
            .addConverterFactory(GsonConverterFactory.create())
            .build();
    NetworkCalls.CustomerApi customerApi = retrofit.create(NetworkCalls.CustomerApi.class);

    Log.e("customerApi  Created", "customerApi object Created : ");

    customerApi.getCategories("eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOjgsImlzcyI6Imh0dHA6XC9cLzE5Mi4xNjguMS42MDo4ODg4XC9DQ1YzXC9wdWJsaWNcL2FwaVwvbG9naW4iLCJpYXQiOjE0NDk0ODg5NDMsImV4cCI6MTQ0OTQ5MjU0MywibmJmIjoxNDQ5NDg4OTQzLCJqdGkiOiI0ODY4ZmNmZDk4OTIxZGQwYjA2ZDZlN2EyYjRjZGMxMSJ9.7c60LRQMFCtqprCbbULgR5xG-FxwXnRUZPuWeMJXcNE")
            .subscribeOn(Schedulers.newThread())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Subscriber<Response<DataCategoryList>>() {
                @Override
                public void onCompleted() {

                    Log.e("onCompleted", "onCompleted : ");

                }

                @Override
                public void onError(Throwable e) {
                    Log.e("onError", "onError : " + e.getMessage());
                    e.printStackTrace();

                    // network errors, e. g. UnknownHostException, will end up here
                }

                @Override
                public void onNext(Response<DataCategoryList> startupResponseResponse) {



                }
            });
}

接口类

public interface CustomerApi {
    @Headers({
            "Accept: application/json"
    })
    @FormUrlEncoded
    @POST("categories")
    Observable<Response<DataCategoryList>> getCategories(@Field("token") String token);

    }

收到 400 个错误请求.

getting 400 Bad Request.

推荐答案

400 听起来像是您从服务器获得的特定错误代码.您可以通过在 Retrofit 上添加 loglevel 来尝试调试.

400 sounds like the specific error code that you are getting from your server. You can try debugging by adding loglevel on Retrofit.

OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();
HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
clientBuilder.addInterceptor(loggingInterceptor);

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(NetworkCalls.BASE_URL)
        .client(clientBuilder.build())
        .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
        .addConverterFactory(GsonConverterFactory.create())
        .build();

向 gradle 添加依赖

add dependencies to gradle

compile 'com.squareup.okhttp3:logging-interceptor:3.3.1'

使用日志级别，您可能会看到一些错误 json 从您的服务器返回.

With the loglevel, you can possibly see some error json back from your server.

示例:

 {"statusCode":400,"message":"Some parameters are missing"}
 D/Retrofit: <--- END HTTP (76-byte body)
