如何使用 Swift 将 Dropbox API 连接到 iOS 应用程序 5

Question

我在将 Dropbox API 连接到我的应用程序时遇到问题。 Dropbox API 文档就在我眼前，我做的一切都是在那里写的。 但是在某些指示的方法中存在错误，我不知道用什么来替换那里指示的实体。 我可以登录，但无法获取令牌，而是出现错误：“-canOpenURL：URL 失败：“dbapi-2://1/connect” - 错误：“操作无法完成。 （OSStatus 错误 -10814。）”

import SwiftyDropbox

class AppDelegate:... {
   func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
        //error Use of undeclared type 'DropboxOAuthCompletion'
        let oauthCompletion: DropboxOAuthCompletion = {
          if let authResult = $0 {
              switch authResult {
              case .success:
                  print("Success! User is logged into DropboxClientsManager.")
              case .cancel:
                  print("Authorization flow was manually canceled by user!")
              case .error(_, let description):
                  print("Error: \(String(describing: description))")
              }
          }
        }
        DropboxClientsManager.handleRedirectURL(url, completion: oauthCompletion)
        return true
    }
}

import SwiftyDropbox

class ViewController:... {
   func openDropboxAutorization() {
        // Legacy authorization flow that grants a long-lived token.
        DropboxClientsManager.authorizeFromController(UIApplication.shared,
                                                      controller: self,
                                                      openURL: { (url: URL) -> Void in
                                                        UIApplication.shared.open(url, options: [:], completionHandler: nil)
        })
        
        //New: OAuth 2 code flow with PKCE that grants a short-lived token with scopes.
        
        //error Use of unresolved identifier 'ScopeRequest'
        let scopeRequest = ScopeRequest(scopeType: .user, scopes: ["account_info.read"], includeGrantedScopes: false)
        DropboxClientsManager.authorizeFromControllerV2(
            UIApplication.shared,
            controller: self,
            loadingStatusDelegate: nil,
            openURL: { (url: URL) -> Void in UIApplication.shared.openURL(url) },
            scopeRequest: scopeRequest
        )
    }
}

这两种方法都是从 DropboxAppi 文档中复制的，但它们都不起作用，我也找不到合适的解决方案。

对于 SwiftyDropBox

在AppDelegate.swift内

import SwiftyDropbox

      func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        /// Add Dropbox
        DropboxClientsManager.setupWithAppKey("<YOUR_APP_KEY>")
        
        return true
      }


 func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    var canHandleUrl = false

      let oauthCompletion: DropboxOAuthCompletion = {
        if let authResult = $0 {
          switch authResult {
          case .success:
            print("Success! User is logged into DropboxClientsManager!")
            
          case .cancel:
            print("Authorization flow was manually canceled by user! ")
            
          case .error(_, let description):
            print("Error: \(String(describing: description))")

          }
        }
      canHandleUrl = DropboxClientsManager.handleRedirectURL(url, completion: oauthCompletion)
    }
    
    return canHandleUrl
  }

现在对于要启动身份验证过程的 ViewController。 在这段代码中，我使用的是 UISwitch

import SwiftyDropBox

     @IBAction func connectDropboxSwitchClicked(_ sender: Any) {
        if connectDropboxSwitch.isOn {
          
          /// https://stackoverflow.com/a/39546950/14414215
          /// openURL deprecated
          let scopeRequest = ScopeRequest(scopeType: .user, scopes: ["account_info.read","files.content.write"], includeGrantedScopes: false)
          DropboxClientsManager.authorizeFromControllerV2(
            UIApplication.shared,
            controller: self,
            loadingStatusDelegate: nil,
            //          openURL: { (url: URL) -> Void in UIApplication.shared.openURL(url) },
            openURL: { (url: URL) -> Void in UIApplication.shared.open( url, options: [:])},
            scopeRequest: scopeRequest
          )
          
        } else {
          print(" connectDropbox Switch:\(connectDropbox)")
        }
      }

您的 Info.plist 应该包含这些，以便重定向返回到您的应用程序

<key>CFBundleURLTypes</key>
    <array>
        <dict>
            <key>CFBundleIdentifier</key>
            <string></string>
            <key>CFBundleTypeRole</key>
            <string>Editor</string>
            <key>CFBundleURLSchemes</key>
            <array>
                <string><YOUR API KEY></string>
            </array>
        </dict>
    </array>
