改装400坏请求

Question

这是我用于网络调用的函数。

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。

Answer 1

在地图中发送数据后，我解决了我的问题。这是我的工作。

     Map<String,String> hashMap=new HashMap<>();
    hashMap.put("client_id","2");
    hashMap.put("client_secret",Constant.CLIENT_SECRET);
    hashMap.put("grant_type",Constant.GRANT_TYPE);
    hashMap.put("username",et_user.getText.toString();
    hashMap.put("password",etpassword.getText().toString());
    Call<LoginDataModel> call=apiInterface.login(hashMap);

在ApiInterface中，我添加了这样一个方法

 @FormUrlEncoded
@POST("oauth/token")
Call<LoginDataModel> login(@FieldMap Map<String, String> options);

400听起来像您从服务器获得的特定错误代码。您可以尝试通过在改造上添加loglevel进行调试。

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添加依赖项

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

使用loglevel，您可能会看到从服务器返回的一些错误json。

示例：

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