之前用的是：
daltoniam/SwiftHTTP · GitHub
https://github.com/daltoniam/SwiftHTTP
但是里面好像不支持download
swift Http download
ios – Download a file with NSURLSession in Swift – Stack Overflow
ios – Download file in swift – Stack Overflow
thibaultCha/TCBlobDownloadSwift · GitHub
不过，后来暂时还是用了之前的SwiftHTTP的get去暂时用做文件下载：
//begin to download file downloadFromUrl_async(self.fileItem.downloadUrl, downloadCompleteHandler: downloadFileCompleteHandler) func downloadFromUrl_async(url:String, downloadCompleteHandler:((String, Bool, NSData?, String?) -> Void)) { print("downloadFromUrl_async url=\(url)") var downloadOk:Bool = false var opt:HTTP? = nil let params:Dictionary<String, AnyObject>? = nil let headers:Dictionary<String, String>? = nil do { opt = try HTTP.GET( url, parameters: params, headers: headers, requestSerializer: JSONParameterSerializer()) opt!.start { response in if let err = response.error { print("url=\(url) with params=\(params) response error= \(err.localizedDescription)") downloadOk = false downloadCompleteHandler(url, downloadOk, nil, err.localizedDescription) return } //print("response.statusCode=\(response.statusCode)") //print("opt finished: \(response.description)") downloadOk = true downloadCompleteHandler(url, downloadOk, response.data, nil) } } catch let httpGetError { print("url=\(url) with params=\(params) got error= \(httpGetError)") downloadOk = false downloadCompleteHandler(url, downloadOk, nil, "\(httpGetError)") } } |
可以得到文件的NSData：
respData=Optional(<504b0304 14000400 08006262 be40a5ab f7fe5a01 00003304 00001300 00005b43 6f6e7465 6e745f54 79706573 5d2e786d 6cac934d 4ec33010 85f73d85 e52d4adc b2400825 ed829f25 74510e60 ec4963d5 b12d8f5b dab3b1e0 |
