Question

我们有一个以本机react-native-keychain使用(like in this issue)库的React-native应用程序：

import * as Keychain from 'react-native-keychain';
 try {
            Keychain.setInternetCredentials(
                'device-id',
                'RANDOMDATA',
                DeviceInfo.getUniqueID().toString(),
                { accessGroup: 'org.reactjs.native.example.myreactapp'})
                .then(() => console.log('Done'))
        } catch (err) {
            console.log("error save", err)
        }

我希望能够在迅速制作的今天的小部件中检索此数据，我需要知道该存储密钥。下面是我应该在小部件上找回它的方法：

let itemKey = "device-id"
let keychainAccessGroupName = "3P********.org.reactjs.native.example.myreactapp"

let queryLoad: [String: AnyObject] = [
      kSecClass as String: kSecClassGenericPassword,
      kSecAttrAccount as String: itemKey as AnyObject,
      kSecReturnData as String: kCFBooleanTrue,
      kSecMatchLimit as String: kSecMatchLimitOne,
      kSecAttrAccessGroup as String: keychainAccessGroupName as AnyObject
    ]

    var result: AnyObject?

    let resultCodeLoad = withUnsafeMutablePointer(to: &result) {
      SecItemCopyMatching(queryLoad as CFDictionary, UnsafeMutablePointer($0))
    }

    if resultCodeLoad == noErr {
      if let result = result as? Data,
        let keyValue = NSString(data: result,
                                encoding: String.Encoding.utf8.rawValue) as String? {

        // Found successfully
        print("device-id : ", keyValue)
      }
    } else {
      print("Error loading from Keychain: \(resultCodeLoad)")
    }

但是它不起作用。您可能已经注意到，我需要将设备ID传递给小部件，因为与Android不同，UUID经常更改，并且我们在每个部件上使用不同的ID，这会阻止小部件正常工作

在APP中更改此代码：

{ accessGroup: 'org.reactjs.native.example.myreactapp'})

到

{ accessGroup: '3P********.org.reactjs.native.example.myreactapp'})
