支付宝(极简版)授权登录不执行andCompletion回调

首先,在xcode 11中,引入了SceneDelegate概念

原因

在支付宝(极简版)授权登录的官方demo里,在ViewController里面调用方法

#pragma mark   ==============点击模拟授权行为==============

- (void)demoAuth
{
   
    NSString *url = @"";  //登陆授权或别的需要跳转到支付宝完成操作的Url
    NSDictionary *params = @{kAFServiceOptionBizParams: @{
                                     @"url": url//@""
                                     },
                             kAFServiceOptionCallbackScheme: @"apsdkdemo",
                             };
    
    [AFServiceCenter callService:AFServiceAuth withParams:params andCompletion:^(AFServiceResponse *response) {
        NSLog(@"授权结果:%@", response.result);
    }];
}

在Appdelegate中的代理方法

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    if ([url.host isEqualToString:@"apmqpdispatch"]) {
        [AFServiceCenter handleResponseURL:url withCompletion:^(AFServiceResponse *response) {
            
            if (AFResSuccess == response.responseCode) {
                NSLog(@"%@", response.result);
            }
        }];
    }
    return YES;
}

// NOTE: 9.0以后使用新API接口
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options
{
    if ([url.host isEqualToString:@"apmqpdispatch"]) {
        [AFServiceCenter handleResponseURL:url withCompletion:^(AFServiceResponse *response) {
            
            if (AFResSuccess == response.responseCode) {
                NSLog(@"%@", response.result);
            }
        }];
    }
    return YES;
}

由于SceneDelegate的引入,app的生命周期发生了变化,Appdelegate里的openURL代理方法被弃用, 导致支付宝登录授权回调andCompletion无响应

解决方法

在SceneDelegate.m写入如下方法:

- (void)scene:(UIScene *)scene openURLContexts:(NSSet<UIOpenURLContext *> *)URLContexts {
    NSEnumerator *enumerator = [URLContexts objectEnumerator];
    UIOpenURLContext *context;
    while (context = [enumerator nextObject]) {
        NSLog(@"context.URL =====%@",context.URL);
        NSLog(@"context.options.sourceApplication ===== %@",context.options.sourceApplication);
        NSString *url = [NSString stringWithFormat:@"%@",context.URL];
        if ([url containsString:@"apmqpdispatch"]) {
            [AFServiceCenter handleResponseURL:context.URL withCompletion:^(AFServiceResponse *response) {
                
                if (AFResSuccess == response.responseCode) {
                    NSLog(@"%@", response.result);
                }
            }];
        }
    }
}

这时ViewController的回调正常执行.代码已由阿里技术人员确认,并且他们说后期会更新相应文档.
