如何解决 android studio 中 Cowin Public API 的错误代码 403？

Question

这是 link 到凯文 Public API:

我一直在尝试使用改装库从 android 工作室的第二个 link 获取状态详细信息。但每次我运行应用程序都显示错误 403。任何帮助将不胜感激！在下面添加我的代码：

创建时 activity:

    Retrofit retrofit = new Retrofit.Builder().baseUrl("https://cdn-api.co-vin.in/api/").addConverterFactory(GsonConverterFactory.create()).build();

        CovidAPI covidAPI = retrofit.create(CovidAPI.class);

        Call<StateMainModel> call = covidAPI.getAllIndiaStates();

        call.enqueue(new Callback<StateMainModel>() {
            @Override
            public void onResponse(Call<StateMainModel> call, Response<StateMainModel> response) {
                if(!response.isSuccessful())
                {
                    Toast.makeText(getApplicationContext(),"Error!!Code: "+response.code()+response.toString(),Toast.LENGTH_SHORT).show();
                    tv.setText(response.toString());
                    return;
                }
                else
                {
                    StateMainModel stateMainModel = response.body();

                    int size = stateMainModel.getStates().size();

                    for(int i=0;i<size;i++)
                    {
                        stateList.add(stateMainModel.getStates().get(i).getState_name());
                    }

                    stateAutoCompleteTextView.setAdapter(stateAdapter);
                }

            }

            @Override
            public void onFailure(Call<StateMainModel> call, Throwable t) {
                Toast.makeText(getApplicationContext(),"Error!! Response: "+t.getMessage(),Toast.LENGTH_LONG).show();
            }
        });

API 界面

@GET("v2/admin/location/states")
    Call<StateMainModel> getAllIndiaStates();

StateMainModel 模型Class

private ArrayList<StateIdNameModel> states;
    private Integer ttl;

    public StateMainModel() {
    }

    public StateMainModel(ArrayList<StateIdNameModel> states,Integer ttl) {
        this.states = states;
        this.ttl = ttl;
    }

    public ArrayList<StateIdNameModel> getStates() {
        return states;
    }

    public void setStates(ArrayList<StateIdNameModel> states) {
        this.states = states;
    }

    public Integer getTtl() {
        return ttl;
    }

    public void setTtl(Integer ttl) {
        this.ttl = ttl;
    }

Answer 1

您必须在请求中设置用户代理才能获得成功响应。请参阅以下 Kotlin 代码：

val okHttpClientBuilder = OkHttpClient.Builder()
val logger = HttpLoggingInterceptor().apply { level = Level.BODY}
okHttpClientBuilder.addNetworkInterceptor { chain ->
                    chain.proceed(chain.request()
                        .newBuilder()
                        .header("User-Agent","Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36")
                        .build())
}.addNetworkInterceptor(logger)
val retrofit = Retrofit.Builder()
                .baseUrl("https://cdn-api.co-vin.in/api/v2/")
                .client(okHttpClientBuilder.build())
                .addConverterFactory(MoshiConverterFactory.create())
                .build()

Answer 2

这是对我有用的 Java 代码：

OkHttpClient client = new OkHttpClient();

        client = new OkHttpClient.Builder().addInterceptor(new Interceptor() {
            @Override
            public okhttp3.Response intercept(Interceptor.Chain chain) throws IOException {

                Request originalRequest = chain.request();
                Request requestWithUserAgent = originalRequest.newBuilder().header("User-Agent","Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36").build();
                return  chain.proceed(requestWithUserAgent);


            }
        }).build();

Answer 3

您首先需要创建一个 class OkHttpClient 的对象，然后您必须向其添加拦截器，因为它需要密钥才能访问 api
