iOS开发 如何判断网络请求是否开启了代理

即便很多公司使用了Https,但是使用Charles,同样是可以破解的，破解方法。网上找了很多方法都是MRC的，这里给大家搞了一个ARC的方法，仅供参考！

- (BOOL)getProxyStatus {
    NSDictionary *proxySettings =  (__bridge NSDictionary *)(CFNetworkCopySystemProxySettings());
    NSArray *proxies = (__bridge NSArray *)(CFNetworkCopyProxiesForURL((__bridge CFURLRef _Nonnull)([NSURL URLWithString:@"http://www.baidu.com"]), (__bridge CFDictionaryRef _Nonnull)(proxySettings)));
    NSDictionary *settings = [proxies objectAtIndex:0];
    
    NSLog(@"host=%@", [settings objectForKey:(NSString *)kCFProxyHostNameKey]);
    NSLog(@"port=%@", [settings objectForKey:(NSString *)kCFProxyPortNumberKey]);
    NSLog(@"type=%@", [settings objectForKey:(NSString *)kCFProxyTypeKey]);
    
    if ([[settings objectForKey:(NSString *)kCFProxyTypeKey] isEqualToString:@"kCFProxyTypeNone"]){
        //没有设置代理
        return NO;
    }else{
        //设置代理了
        return YES;
    }
}
