你能否在代码中指出我的错误,我无法向拦截器添加标题“授权”。当我发出请求时,它会抛出错误 retrofit2.adapter.rxjava.HttpException:HTTP 401 Unauthorized 。但是当我为每个请求添加标头令牌时
@Header("Authorization") String token
然后它有效。
这是我的代码:
protected Retrofit retrofit;
protected OkHttpClient client;
protected T api;
protected UserCredential userCredential;
public RestClient(Class<T> type) {
if (client == null) {
synchronized (OkHttpClient.class) {
client = new OkHttpClient();
client.newBuilder().addInterceptor(chain -> {
Request original = chain.request();
Request.Builder builder = original.newBuilder();
if (GrabDoiApplication.getInstance().getCurrentCredentials() != null) {
String token = GrabDoiApplication.getInstance().getCurrentCredentials().getToken();
if (token != null) {
builder.addHeader("Authorization", token);
}
}
builder.method(original.method(), original.body());
return chain.proceed(builder.build());
}).build();
if (retrofit == null) {
synchronized (Retrofit.class) {
Retrofit.Builder retrofitBuilder = new Retrofit.Builder()
.baseUrl(Constants.GRABDOI_SERVER_URL)
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create());
retrofit = retrofitBuilder.build();
}
}
}
}
api = retrofit.create(type);
}
答案 0 :(得分:2)
您可以尝试将对静态方法的访问权限放在拦截器的主体之外:
public RestClient(Class<T> type) {
if (retrofit != null) {
return;
}
synchronized (OkHttpClient.class) {
client = new OkHttpClient();
OkHttpClient.Builder builder = client.newBuilder();
final String token;
if (GrabDoiApplication.getInstance().getCurrentCredentials() != null &&
(token = GrabDoiApplication.getInstance().getCurrentCredentials().getToken()) != null) {
builder.addInterceptor(chain -> {
Request.Builder builder = chain.request().newBuilder();
builder.addHeader("Authorization", token);
builder.method(original.method(), original.body());
return chain.proceed(builder.build());
});
}
client = builder.build();
synchronized (Retrofit.class) {
Retrofit.Builder retrofitBuilder = new Retrofit.Builder()
.baseUrl(Constants.GRABDOI_SERVER_URL)
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create());
retrofit = retrofitBuilder.build();
}
}
api = retrofit.create(type);
}
