swift – 无法打开文件“xxx.mp4”,因为您无权查看它

概述我使用Alamofire方法multipartFormData.append(URL,withName：“file”)将视频上传到服务器,但我收到一条错误消息： multipartEncodingFailed(Alamofire.AFError.MultipartEncodingFailureReason.bodyPartFileNotReachableWithError(file:///var/ 我使用Alamofire方法multipartFormData.append(URL,withname：“file”)将视频上传到服务器,但我收到一条错误消息：

multipartEnCodingFailed(Alamofire.AFError.MultipartEnCodingFailureReason.bodyPartfileNotReachableWithError(file:///var/mobile/Media/DCIM/100APPLE/img_0939.mp4,Error Domain=NSCocoaErrorDomain Code=257 “The file “img_0939.mp4” Couldn’t be opened because you don’t have permission to vIEw it.” UserInfo={NSURL=file:///var/mobile/Media/DCIM/100APPLE/img_0939.mp4,NSfilePath=/var/mobile/Media/DCIM/100APPLE/img_0939.mp4,NSUnderlyingError=0x174450d10 {Error Domain=NSPOSIXErrorDomain Code=1 “Operation not permitted”}}))

我已打开隐私 – 照片库使用说明但我收到此错误,我不知道.

我的代码：

alamofireManager?.upload(    multipartFormData: { multipartFormData in        for i in 0..<vIDeoURLs.count {            multipartFormData.append(vIDeoURLs[i],withname: "file")        }    },to: url + urlString,headers: headers,enCodingCompletion: { enCodingResult in        switch enCodingResult {        case .success(let upload,_,_):            upload.uploadProgress(closure: { (progress) in                //Print progress                //print(progress)            })            upload.responseJsON { response in                if let value = response.result.value as? [String: AnyObject]{                    success(value)                }            }        case .failure(let enCodingError):            failture(enCodingError)        }    })

解决方法 你需要使用 startAccessingSecurityScopedResource

if let url = file.url,url.startAccessingSecurityScopedResource() {    multipartFormData.append(url,withname: "some-file.pdf")    // After using the resource make sure you stop the access    if url.startAccessingSecurityScopedResource() {        url.stopAccessingSecurityScopedResource()    }}
