【代码】IOS检查是否开启了网络代理_iOS开发

在网络请求之前，进行下系统代理的判断，如果系统开启了代理，则停止后面的网络请求，这样就可以解决数据被抓包问题

- (BOOL) checkProxySetting {
    NSDictionary *proxySettings = (__bridge NSDictionary *)(CFNetworkCopySystemProxySettings());
    NSArray *proxies = (__bridge NSArray *)(CFNetworkCopyProxiesForURL((__bridge CFURLRef _Nonnull)([NSURL URLWithString:@"https://www.baidu.com"]), (__bridge CFDictionaryRef _Nonnull)(proxySettings)));
    NSLog(@"\n%@",proxies);

    NSDictionary *settings = proxies[0];
    NSLog(@"%@",[settings objectForKey:(NSString *)kCFProxyHostNameKey]);
    NSLog(@"%@",[settings objectForKey:(NSString *)kCFProxyPortNumberKey]);
    NSLog(@"%@",[settings objectForKey:(NSString *)kCFProxyTypeKey]);

    if ([[settings objectForKey:(NSString *)kCFProxyTypeKey] isEqualToString:@"kCFProxyTypeNone"])
    {
        NSLog(@"没设置代理");
        return NO;
    }
    else
    {
        
        NSLog(@"设置了代理");
        return YES;
    }
}
