我创建了一个 macOS ShareExtension,我想用它来上传图片。
我仍在对此进行测试,因此任何请求都将发送到https://beeceptor.com。
共享扩展工作正常,一旦我运行它就会显示在预览中:
我添加一些文字并点击“发布”
但是图像不会上传。这是我启动后台上传的代码:
let sc_uploadURL = "https://xyz.free.beeceptor.com/api/posts" // https://beeceptor.com/console/xyz
override func didSelectPost() {
// This is called after the user selects Post. Do the upload of contentText and/or NSExtensionContext attachments.
let configName = "com.shinobicontrols.ShareAlike.BackgroundSessionConfig"
let sessionConfig = URLSessionConfiguration.background(withIdentifier: configName)
// Extensions aren't allowed their own cache disk space. Need to share with application
sessionConfig.sharedContainerIdentifier = "group.CreateDaily"
let session = URLSession(configuration: sessionConfig)
// Prepare the URL Request
let request = urlRequestWithImage(image: attachedImage, text: contentText)
// Create the task, and kick it off
let task = session.dataTask(with: request! as URLRequest)
task.resume()
// Inform the host that we're done, so it un-blocks its UI. Note: Alternatively you could call super's -didSelectPost, which will similarly complete the extension context.
extensionContext?.completeRequest(returningItems: [AnyObject](), completionHandler: nil)
}
private func urlRequestWithImage(image: NSImage?, text: String) -> NSURLRequest? {
let url = URL(string: sc_uploadURL)!
let request: NSMutableURLRequest? = NSMutableURLRequest(url: url as URL)
request?.addValue("application/json", forHTTPHeaderField: "Content-Type")
request?.addValue("application/json", forHTTPHeaderField: "Accept")
request?.httpMethod = "POST"
let jsonObject = NSMutableDictionary()
jsonObject["text"] = text
if let image = image {
jsonObject["image_details"] = extractDetailsFromImage(image: image)
}
// Create the JSON payload
let jsonData = try! JSONSerialization.data(withJSONObject: jsonObject, options: JSONSerialization.WritingOptions.prettyPrinted)
request?.httpBody = jsonData
return request
}
请注意,sharedContainerIdentifier
它存在于应用程序的权利以及共享扩展权利中。
ShareExtensions 位于相应的应用程序组中,并启用了传出连接。
