Retrofit2 發送 Bearer Token

Question

我嘗試使用 HeaderMap 發送令牌，但得到 401 代碼響應。 我的項目設置方式是我有一個單獨的文件用於我的ApiClient ，我有一個OkHttpClient Interceptor和一個HttpLoggingInterceptor來查看發生了什么，但是我無法讓承載令牌工作。 我已經看到將它作為攔截器中的 header 添加到攔截器的解決方案，我已經嘗試過了，但是由於我的令牌保存在 SharedPreferences 中，我無法讓它在我擁有的 ApiClient class 中工作。

這是 ApiClient

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

Gson gson = new GsonBuilder().serializeNulls().setLenient().create();

OkHttpClient okHttpClient = new OkHttpClient.Builder()
        .addInterceptor(new Interceptor() {
            @NotNull
            @Override
            public okhttp3.Response intercept(@NotNull Chain chain) throws IOException {
                Request originalRequest = chain.request();
                Request newRequest = originalRequest.newBuilder()
                //I would add the header here
                //I tried this but it says on "ApiClient.this" cannot be referenced from static context
                // .header("Authorization" , SharedPreferencesHelper.getUserToken(ApiClient.this));
                        .build();

                return chain.proceed(newRequest);
            }
        })
        .addInterceptor(interceptor)
        .build();

retrofit = new Retrofit.Builder()
        .baseUrl("http://192.168.0.6:8000/api/")
        .addConverterFactory(GsonConverterFactory.create())
        .client(okHttpClient)
        .build();

這是來自SharedPreferencesHelper.getUserToken(MainActivity.this)的方法

public static String getUserToken(Context context) {
    SharedPreferences sp = getSharedPreferences(context);
    return sp.getString(USER_TOKEN, null);
}

這是響應為 401 的當前調用，如果我不添加 Accept => application/json，則響應 url 不正確，並且當我需要簡單響應時返回一個 html 頁面return response("LoggedOut", 200); //this is the response in the api return response("LoggedOut", 200); //this is the response in the api

Map<String, String> headers = new HashMap<>();
headers.put("Accept", "application/json");
headers.put("Token", SharedPreferencesHelper.getUserToken(MainActivity.this));

Call<Void> call = apiInterface.LogoutUser(headers);

call.enqueue(new Callback<Void>() {
    // onResponse and onFailure here
}

例如，沒有 Accept header 這是 Logcat 中的響應

D/OkHttp: --> GET http://192.168.0.6:8000/api/logout
D/OkHttp: Token: wE1Y8IxJpwyXtvw0fYoXZAlQ6qCx24YtzonQIeJBQSHmNppe0Sn1kLYDgZKCw4MKbpab4Vspf61Nzer1
D/OkHttp: --> END GET
D/OkHttp: <-- 200 OK http://192.168.0.6:8000/login
//a bunch of html that's the web page at this route, notice the /api is missing 

我怎樣才能正確發送這個？

編輯：我正在使用 Laravel 項目作為后端，這是相關路線

Route::middleware('auth:sanctum')
    ->get('/logoutApi', function (Request $request) {

    $request->user()->tokens()->delete();

    return response("LoggedOut", 202);
});

Answer 1

創建 class 身份驗證器，例如：

const val HEADER_TOKEN_FIELD = "Authorization"
class ClassAuthenticator(
    private val pref: SharedPref
) : Authenticator {
    override fun authenticate(route: Route?, response: Response): Request? {

        return response.request().newBuilder()
                .header(HEADER_TOKEN_FIELD, pref.getToken())
                .build()
    }
}

然后在您的客戶端中添加攔截器：

 val httpClient = OkHttpClient.Builder()
            .authenticator(ClassAuthenticator(pref))
            .addInterceptor { chain ->
                val request = chain.request()
                val httpRequest = request.newBuilder()
                        .addHeader(HEADER_TOKEN_FIELD, 
                          "Bearer ${pref.getToken()}")
                        .build()
                val response = chain.proceed(httpRequest)
                response
            }
            .build()
