IOS获取代理设置 [英] IOS Get Proxy Settings

问题描述

在我的项目中，我使用libcurl通过互联网下载数据。问题是libcurl没有检测到wifi连接的代理设置。

In my project i am using libcurl to download data over internet. The problem is that libcurl doesn't detect the proxy settings of the wifi connection.

我必须手动设置libcurl的设置所以我想知道如何获得wifi连接的代理设置。我在KeyChain中找到了一些关于信息的线索，但我无法检索它们。

I must set manually the settings for libcurl so i'm wondering how can a get the proxy settings of a wifi connection. I found some clues about informations in the KeyChain but i was unable to retrieve them.

你知道是否有办法获得这个设置所以我可以设置它们libcurl？

Do you know if there is a way to get this settings so i can set them for libcurl ?

谢谢！

推荐答案

我找到了回复！

使用这段代码似乎有效：

Using this bit of code seems to work :

std::string getProxyName()
{
    CFDictionaryRef dicRef = CFNetworkCopySystemProxySettings();
    const CFStringRef proxyCFstr = (const CFStringRef)CFDictionaryGetValue(dicRef, (const void*)kCFNetworkProxiesHTTPProxy);
    char buffer[4096];
    memset(buffer, 0, 4096);
    if (CFStringGetCString(proxyCFstr, buffer, 4096, kCFStringEncodingUTF8))
    {
        return std::string(buffer);
    }
    return "";
}


int CDownloadThread::getProxyPort()
{
    CFDictionaryRef dicRef = CFNetworkCopySystemProxySettings();
    const CFNumberRef portCFnum = (const CFNumberRef)CFDictionaryGetValue(dicRef, (const void*)kCFNetworkProxiesHTTPPort);

    SInt32 port;
    if (CFNumberGetValue(portCFnum, kCFNumberSInt32Type, &port))
    {
        return port;
    }
    return -1;
}

我还没有尝试使用自动代理配置，但我希望它能正常工作！

I haven't try with automatic proxy configuration yet but i hope it's working !
