如何在ios中实现刷新令牌

Question

只有一些api调用需要令牌。当401发生时，将对每个调用采取刷新令牌调用( place.and )，令牌将刷新。当401发生时如何同步执行多个api

Answer 1

这取决于您是如何设计流程的，但我做的问题与目标C中的类似

• 在我的例子中调用类似的方法userProfileGETRequest
• 在调用userProfileGETRequest之前，如果令牌过期，请检查日期(在您的情况下，可能是状态代码== 401)
• 如果令牌未过期，只需使用最后一个令牌调用API (在我的例子中是userProfileAPI )。
• 如果令牌过期，则调用Refresh令牌，并成功和失败地回调
• 如果成功刷新令牌，则使用更新的刷新令牌调用userProfileAPI API .。
  • ( userProfileGETRequest:(NSDictionary *)headerParams urlQuery：(NSString*)操作参数：(NSDictionary*)params docOpenPassword：(NSString*)密码docOpenOtp：(NSString*)otp onComplete:(void (^)(id json，id code，id url))successBlock onError:(void (^)(id (^)，id code，id url))errorBlock {if ([SingletonSDK sharedInstance isTokenExpired:NSDate date date]) {[自引用action:nil：(id json，id code，id url)]{id代码){ [SingletonSDK sharedInstance handleLoginResponseObject:json]；自用户userProfileAPI:headerParams urlQuery:action参数:params onComplete:^(id json，id代码，id url) { successBlock(json，code，url)；} onError:^(id错误，id代码，id url) {errorBlock(错误，代码，url)；}；}{ [SingletonSDK sharedInstance hideProgessHud]；返回；}}{ successBlock(json，code，url) {successBlock( json，code，url){successBlock(json，code，url)；} onError:^(id错误，id代码，id url) {errorBlock(错误，代码，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);
     }

 }];
