Multiple NSHTTPCookieStorage in the same app

由 ∥☆過路亽．° 提交于 2019-12-06 06:13:36
I am writing a multi-user app using NSURLSession and I can't figure out how to have a separate cookie storage when working with multiple NSURLSession instances. I tried setting NSURLSessionConfiguration 's HTTPCookieStorage property with a NSHTTPCookieStorage that I alloc/init'ed myself but it doesn't work (cookies aren't stored, even if I call setCookie: myself) I also tried using [NSURLSessionConfiguration ephemeralSessionConfiguration] but then again, my cookies aren't stored between requests. The Set-Cookie header is present in the server's responses, and using [NSHTTPCookieStorage

NSURLSessionTask authentication challenge completionHandler and NSURLAuthenticationChallenge client

由 感情迁移 提交于 2019-12-06 06:08:48
问题 I am implementing a custom NSURLProtocol , and internally want to use NSURLSession with data tasks for internal networking instead of NSURLConnection . I have hit an interesting problem and wonder about the internal implementation of the challenge handler of NSURLSession / NSURLSessionTask . - (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition

NSURLSessionUploadTask get response data

I have some misunderstanding in using NSURLSession framework, that's why I decided to write small app from scratch without AFFramework/Alamofire. I have an API that requires following steps to upload file: POST file data Get response (JSON) Post some json fields to api/save I have a background session with such config: let configuration = NSURLSessionConfiguration.backgroundSessionConfigurationWithIdentifier("myBackground") let session = NSURLSession(configuration: configuration, delegate: self, delegateQueue: nil) I've implemented 2 methods: func URLSession(session: NSURLSession, dataTask:

NSURLSession, upload task - Get actual bytes transferred

由 心不动则不痛 提交于 2019-12-06 03:46:03
问题 I was getting bug reports that my iOS app failed upload of images on slow connections. While my timeout probably wasn't high enough, there was another issue. I found that upload progress quickly went to 100% even though I could see in Charles that bytes were still being transferred. I use the following method of NSURLSession: - (NSURLSessionUploadTask *)uploadTaskWithRequest:(NSURLRequest *)request fromData:(NSData *)bodyData completionHandler:(void (^)(NSData *data, NSURLResponse *response,

NSURLSession - download and do *not* decompress gzip?

由 扶醉桌前 提交于 2019-12-06 03:35:46
问题 I'm using NSURLSession 's dataTaskWithRequest to download a file. It's gzipped, and it is automatically decompressed. However, I don't want it to be - I want the gzipped source. Is there any way to disable decompression? 回答1: NSURLSession automatically inserts this value to your request's header: "Accept-Encoding: gzip;q=1.0, compress;q=0.5" which causes the downloaded data to be automatically decoded. So I think you should start by replacing the value of "Accept-Encoding" with something else

Unit tests with NSURLSession

由 旧时模样 提交于 2019-12-06 02:47:32
问题 I'd like to write unit tests for methods that use the shared NSURLSession , and in particular, NSURLSessionDataTask to download data. Basically, I would like the target methods to receive mock responses/data without requiring an internet connection. What is the less unobtrusive way of mocking these components? I was thinking of populating NSURLCache with mock responses and data but I feel this assumes too much of how NSURLSession and NSURLSessionDataTask work. Any other suggestions? 回答1: I've
