我有一個自定義URLProtocol,我想通過代理服務器重定向所有流量。使用自定義NSURLProtocol和HTTP代理處理重定向
我當前工作的代碼看起來像這樣:
+(BOOL)canInitWithRequest:(NSURLRequest*)request
{
if ([NSURLProtocol propertyForKey:protocolKey inRequest:request])
return NO;
NSString *scheme = request.URL.scheme.lowercaseString;
return [scheme isEqualToString:@"http"] || [scheme isEqualToString:@"https"];
}
-(void)startLoading
{
NSMutableURLRequest *request = self.request.mutableCopy;
[NSURLProtocol setProperty:@YES forKey:protocolKey inRequest:request];
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
config.requestCachePolicy = NSURLRequestReloadIgnoringLocalCacheData;
config.connectionProxyDictionary = @
{
(id)kCFNetworkProxiesHTTPEnable:@YES,
(id)kCFNetworkProxiesHTTPProxy:@"1.2.3.4",
(id)kCFNetworkProxiesHTTPPort:@8080
};
m_session = [NSURLSession sessionWithConfiguration:config delegate:self delegateQueue:[NSOperationQueue currentQueue]];
[[m_session dataTaskWithRequest:request] resume];
}
這個偉大的工程至今。問題是有一些URL使用重定向 - 我希望重定向也由代理服務器執行,而不是由設備執行。我試着添加以下代碼,但它並沒有幫助:
-(void)URLSession:(NSURLSession*)session task:(NSURLSessionTask*)task willPerformHTTPRedirection:(NSHTTPURLResponse*)response newRequest:(NSURLRequest*)newRequest completionHandler:(void (^)(NSURLRequest*))completionHandler
{
NSMutableURLRequest *request = newRequest.mutableCopy;
[NSURLProtocol removePropertyForKey:protocolKey inRequest:request];
[self.client URLProtocol:self wasRedirectedToRequest:request redirectResponse:response];
[task cancel];
[self.client URLProtocol:self didFailWithError:[NSError errorWithDomain:NSCocoaErrorDomain code:NSUserCancelledError userInfo:nil]];
}
的問題是,新的請求沒有被髮送到代理服務器,而是由設備本身重定向。
謝謝。
什麼是m_session在' - (空)startLoading'?你有可能發佈完整的URLProtocol文件嗎? – 2016-02-25 18:54:45
@SamHeather m_session就是我保存NSURLSession實例的地方。有一個很好的教程(使用NSURLConnection代替),我用它作爲起點:http://www.raywenderlich.com/59982/nsurlprotocol-tutorial – 2016-02-25 21:25:50
您是否有任何想法如何將connectionProxy應用於NSURLConnection或NSMutableURLRequest?尋找文檔觸摸缺乏這... – 2016-02-25 21:56:03
