无法使用刷新的令牌改造请求

【问题标题】：Unable to request with refreshed Token Retrofit无法使用刷新的令牌改造请求
【发布时间】：2020-11-22 21:36:52
【问题描述】：

我正在使用拦截器来刷新我过期的令牌。刷新后，我尝试使用新的刷新令牌发送原始请求。但是我无法使用新的 Token 发送请求。

如果令牌有效。应用程序运行良好。但是当 Token 无效时。我认为片段中的网络请求在刷新令牌请求之前......

请指导我...

拦截器

public class HttpInterceptor implements Interceptor {

@Override
public Response intercept(Chain chain) throws IOException {
    Request request = chain.request();

    //Build new request
    Request.Builder builder = request.newBuilder();
    builder.header("Accept", "application/json"); //if necessary, say to consume JSON

    String token = PrefUtils.getAppToken(HelloApplication.getContext()); //save token of this request for future
    setAuthHeader(builder, token); //write current token to request

    request = builder.build(); //overwrite old request
    Response response = chain.proceed(request); //perform request, here original request will be executed

    String body = response.peekBody(2048).string();
    try {
        APIStatus stat = new Gson().fromJson(body, APIStatus.class);
        Log.e("ARUL intercept: ", stat.getMessage());
        if (stat.getMessage().contains("Invalid Auth Token")) { //if unauthorized
            synchronized (this) { //perform all 401 in sync blocks, to avoid multiply token updates
                String currentToken = PrefUtils.getAppToken(HelloApplication.getContext()); //get currently stored token

                if (currentToken != null && currentToken.equals(token)) { //compare current token with token that was stored before, if it was not updated - do update

                    int code = refreshToken() / 100; //refresh token
                    if (code != 2) { //if refresh token failed for some reason
                        if (code == 4) //only if response is 400, 500 might mean that token was not updated
                            logout(); //go to login screen
                        return response; //if token refresh failed - show error to user
                    }
                }

                if (PrefUtils.getAppToken(HelloApplication.getContext()) != null) { //retry requires new auth token,
                    setAuthHeader(builder, PrefUtils.getAppToken(HelloApplication.getContext())); //set auth token to updated
                    request = builder.build();
                    return chain.proceed(request); //repeat request with new token
                }
            }
        }
    } catch (IllegalStateException | JsonSyntaxException exception) {
        Log.e("ARUL intercept: ", "GOT VALID REPSONSE!!! ");
    }

    return response;
}

private void setAuthHeader(Request.Builder builder, String token) {
    if (token != null) //Add Auth token to each request if authorized
        builder.header("auth_token", token);
}

private int refreshToken() {
    //Refresh token, synchronously, save it, and return result code
    //you might use retrofit here
    int status = 2;
    HelloApi mHelloApi = ServiceGenerator.provideHelloService();

    HashMap<String, RequestBody> partMap = new HashMap<>();
    String ID = PrefUtils.getUserID(HelloApplication.getContext());
    partMap.put("user_id", Utils.createPartFromString(ID));

    Call<APIStatus> register = mHelloApi.requestAccessToken(partMap);

    APIStatus mAPI = register.execute().body();
    PrefUtils.updateToken(HelloApplication.getContext(), mAPI.getToken());

    return status;
}

private int logout() {
    //logout your user
    return 4;
}

}

更新

Refreshed Token 已成功存储在共享 Prefs 中。但是在重试原始请求时。它还在使用旧令牌吗？我该如何解决？

【问题讨论】：

  • 我建议做一个简单的复制并发布，请参阅sscce.org 其他人很难帮助解决这个问题。

标签： java android retrofit retrofit2 okhttp


【解决方案1】：

这个问题的原因是 refreshToken() 方法。您正在尝试进行异步调用，这意味着改造将创建另一个线程来执行刷新令牌 api。

而不是调用 register.enqueue 你应该调用它是异步的

register.execute 这将进行同步调用，并且应该从后台线程中使用。 例如查看此link

【讨论】：

  • 您的建议很有帮助。但是在重试原始请求时它仍然附加旧令牌？请检查更新....
  • @user3467240 您能否添加一个登录 setAuthHeader() 方法来确认我们是否确实从 sharedPreferences 获取了新令牌。
