【问题描述】：

只有一些 api 调用需要令牌。当 401 发生时，将进行刷新令牌调用。对于每次调用，令牌都会刷新。 401发生时如何同步执行1个以上的api

【参考方案1】：

这取决于你如何设计流程，但我在 Objective C 中做了几乎相同的问题

在我的例子中调用方法 userProfileGETRequest 在调用 userProfileGETRequest 之前检查令牌是否过期（在您的情况下可能是状态码 == 401） 如果令牌没有过期，在我的例子中只需调用 API userProfileAPI 与最后一个令牌 如果令牌过期，则调用刷新令牌并带有成功和失败回调

如果成功刷新令牌，则使用更新的刷新令牌调用 userProfileAPI API。

    + (void) userProfileGETRequest:(NSDictionary *)headerParams urlQuery: (NSString*)action parameters:(NSDictionary*)params docOpenPassword: (NSString*)password docOpenOtp: (NSString*)otp
            onComplete:(void (^)(id json, id code, id url))successBlock
               onError:(void (^)(id error, id code, id url))errorBlock if ([[SingletonSDK sharedInstance] isTokenExpired:[NSDate date]]) [self refereshToken:nil :^(id json, id code) 
    [[SingletonSDK sharedInstance] handleLoginResponseObject:json];

        [self userProfileAPI:headerParams urlQuery:action parameters:params

                  onComplete:^(id json, id code, id url) 
                      successBlock(json, code, url);
                   onError:^(id error, id code, id url) 
                      errorBlock(error, code, url);
                  ];

     onError:^(id error, id code) 
        [[SingletonSDK sharedInstance] hideProgessHud];
        return ;
    ];


 else 
    [self userProfileAPI:headerParams urlQuery:action parameters:params
              onComplete:^(id json, id code, id url) 
                  successBlock(json, code, url);
               onError:^(id error, id code, id url) 
                  errorBlock(error, code, url);
              ];

//userProfileAPI 方法

+ (void) userProfileAPI:(NSDictionary *)headerParams urlQuery: (NSString*)action parameters:(NSDictionary*)params 
                                         onComplete:(void (^)(id json, id code, id url))successBlock
                                            onError:(void (^)(id error, id code, id url))errorBlock


NSString *authorizationValue = [self setAuthorizationValue:action];
NSString *language = [self editedLanguageNameAsApiRequired];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

//set headers values
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[manager.requestSerializer setValue:language forHTTPHeaderField:@"Accept-Language"];
[manager.requestSerializer setValue:authorizationValue forHTTPHeaderField:@"authorization"];

[manager GET:action parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) 
    NSLog(@"getRequest response success");
    NSString *url = [[[operation response] URL] absoluteString];
    NSInteger statusCode = [operation.response statusCode];
    NSNumber *statusObject = [NSNumber numberWithInteger:statusCode];

    successBlock(responseObject, statusObject, url);

     failure:^(AFHTTPRequestOperation *operation, NSError *error)
 
     NSString *url = [[[operation response] URL] absoluteString];
     NSInteger statusCode = [operation.response statusCode];
     NSNumber *statusObject = [NSNumber numberWithInteger:statusCode];
     if ([self takeDesiredActionIfAccessTokenExpired:statusCode]) 
         return ;
     
     id responseObject = operation.responseData;
     id json = nil;
     id errorMessage = nil;

     if ([statusObject integerValue] == 404) 
         errorMessage = [[SingletonSDK sharedInstance] getStringValueFromLanguageKey: COMMON_ERROR_SHARED_PREFERENCES];//NSLocalizedString(COMMON_ERROR_RESOURCE_NOT_FOUND, nil);
      else 
         if (responseObject) 

             json = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:&error];
             errorMessage = [(NSDictionary*)json objectForKey:@"Message"];

         else

             json = [error.userInfo objectForKey:NSLocalizedDescriptionKey];
             errorMessage = json;

         
     


     if(![errorMessage isKindOfClass:[NSString class]])
         errorMessage = [[SingletonSDK sharedInstance] getStringValueFromLanguageKey: COMMON_ERROR_MSG] ; //NSLocalizedString(COMMON_ERROR_MSG, nil);
