// 检测代理
-(void)getProxyStatus {
    NSDictionary *proxySettings = (__bridge NSDictionary *)(CFNetworkCopySystemProxySettings());
    NSArray *proxies = (__bridge NSArray *)(CFNetworkCopyProxiesForURL((__bridge CFURLRef _Nonnull)([NSURL URLWithString:@"https://www.baidu.com/"]), (__bridge CFDictionaryRef _Nonnull)(proxySettings)));
    NSDictionary *settings = proxies[0];
    if (![[settings objectForKey:(NSString *)kCFProxyTypeKey] isEqualToString:@"kCFProxyTypeNone"]){
        //检测到连接代理
    }
