如何以编程方式将代理添加到NSURLSession

查看NSURLSession和NSURLSessionConfiguration的文档，我觉得我应该用像下面这样的字典来configuration它：

  // Create a dictionary to describe the proxy NSDictionary *proxyDict = @{ (NSString *)kCFProxyHostNameKey : @"myProxyHost.com", (NSString *)kCFProxyPortNumberKey : @"12345", (NSString *)kCFProxyTypeKey : (NSString*)kCFProxyTypeHTTP }; // Create a configuration that uses the dictionary NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; [configuration setConnectionProxyDictionary:proxyDict]; 

但是，使用此configuration创build的NSURLSession的请求直接连接。

事实certificate，你想要的字典键是Stream变体，它们是parsing为“HTTPProxy”的那些：

 NSString* proxyHost = @"myProxyHost.com"; NSNumber* proxyPort = [NSNumber numberWithInt: 12345]; // Create an NSURLSessionConfiguration that uses the proxy NSDictionary *proxyDict = @{ @"HTTPEnable" : [NSNumber numberWithInt:1], (NSString *)kCFStreamPropertyHTTPProxyHost : proxyHost, (NSString *)kCFStreamPropertyHTTPProxyPort : proxyPort, @"HTTPSEnable" : [NSNumber numberWithInt:1], (NSString *)kCFStreamPropertyHTTPSProxyHost : proxyHost, (NSString *)kCFStreamPropertyHTTPSProxyPort : proxyPort, }; NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration ephemeralSessionConfiguration]; configuration.connectionProxyDictionary = proxyDict; // Create a NSURLSession with our proxy aware configuration NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:[NSOperationQueue mainQueue]]; // Form the request NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.google.com?2"]]; // Dispatch the request on our custom configured session NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler: ^(NSData *data, NSURLResponse *response, NSError *error) { NSLog(@"NSURLSession got the response [%@]", response); NSLog(@"NSURLSession got the data [%@]", data); }]; NSLog(@"Lets fire up the task!"); [task resume]; 

Answer 2

如果有人需要这个快速版本：

Swift 3

 let sessionConfiguration = URLSessionConfiguration.default sessionConfiguration.connectionProxyDictionary = [ kCFNetworkProxiesHTTPEnable as AnyHashable: true, kCFNetworkProxiesHTTPPort as AnyHashable: 999, //myPortInt kCFNetworkProxiesHTTPProxy as AnyHashable: "myProxyUrlString" ] let session = URLSession(configuration: sessionConfiguration) 

Answer 3

由于杰夫的几个答案键已被弃用，我使用这些

 NSMutableDictionary *proxy=[NSMutableDictionary dictionaryWithDictionary:@{(__bridge NSString *)kCFNetworkProxiesHTTPEnable : @1, (__bridge NSString *)kCFNetworkProxiesHTTPSEnable : @1}]; proxy[(__bridge NSString *)kCFNetworkProxiesHTTPProxy] =host; proxy[(__bridge NSString *)kCFNetworkProxiesHTTPSProxy]=host; proxy[(__bridge NSString *)kCFNetworkProxiesHTTPPort] =port; proxy[(__bridge NSString *)kCFNetworkProxiesHTTPSPort] =port; proxy[(__bridge NSString *)kCFProxyUsernameKey]=user; proxy[(__bridge NSString *)kCFProxyPasswordKey]=password; configuration.connectionProxyDictionary=proxy; 

Answer 4

kCFProxyPortNumberKey值应该是Int不是String

Answer 5

Swift 3扩展

 extension URLSession { func withProxy(proxyURL: String, proxyPort: Int) -> URLSession { var configuration = self.configuration configuration.connectionProxyDictionary = [ kCFNetworkProxiesHTTPEnable as AnyHashable : true, kCFNetworkProxiesHTTPPort as AnyHashable : proxyPort, kCFNetworkProxiesHTTPProxy as AnyHashable : proxyURL ] return URLSession(configuration: configuration, delegate: self.delegate, delegateQueue: self.delegateQueue) } } 

用法：

 let session = URLSession().withProxy(proxyURL: "xxxxxx", proxyPort: 8321) 

Answer 6

根据之前的所有回应，这适用于Swift 4，包括HTTP和HTTPS：

 let proxyHost = "127.0.0.1" let proxyPort = 8888 let configuration = URLSessionConfiguration.default configuration.connectionProxyDictionary = [ kCFNetworkProxiesHTTPEnable: true, kCFNetworkProxiesHTTPProxy: proxyHost, kCFNetworkProxiesHTTPPort: proxyPort, kCFNetworkProxiesHTTPSEnable: true, kCFNetworkProxiesHTTPSProxy: proxyHost, kCFNetworkProxiesHTTPSPort: proxyPort ] 

proxyHost应该是一个主机名，不包含任何URLscheme。
