javascript - 如何通过 npm 安装 CloudKit JS 库

Question

我目前正在使用 CloudKit JS API 并使用 Node.js 编写脚本。

我安装了Apple提供的cloud kit库here通过这样做:

curl "https://cdn.apple-cloudkit.com/ck/2/cloudkit.js" > cloudkit.js

脚本是下一个:

var fetch = require("node-fetch");
var CloudKit = require("./cloudkit.js");

CloudKit.configure({
    services: {fetch: fetch},
    containers: [{
        containerIdentifier: 'CONTAINER',
        apiToken: 'TOKEN',
        environment: 'development'
    }]
});

var container = CloudKit.getDefaultContainer();
container.setUpAuth();
var publicDB = container.publicCloudDatabase;

function demoPerformQuery() {
    publicDB.performQuery({recordType: 'Schedule'}).then(function(response){
        console.log(response)
    }).catch(function(error){
        console.log(error)
    })
}

demoPerformQuery();

运行时的输出是:

(node:30096) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): [CKError
    ckErrorCode: AUTHENTICATION_FAILED
    extensionErrorCode: undefined
    isCKError: true
    isError: true

    isServerExtensionError: true

    name: Error
    reason: no auth method found
    recordName: undefined

]

  _retryAfter: undefined,
  _recordName: undefined,
  _subscriptionID: undefined,

  _redirectURL: undefined,

正如我在StackOverflow中读到的那样解决方案可能是使用 npm 安装它，但作为 Node 新手，我陷入了 npm run-script install-cloudkit-js 的困境，因为我没有该脚本，而且不知道如何继续。

看来您的问题与 container.setUpAuth(); 的 promise 有关

尝试更改您的代码，使其看起来更像这样:

  var fetch = require('node-fetch');

  var CloudKit = require('./cloudkit');

  CloudKit.configure({
      services: {fetch: fetch},
      containers: [{
         containerIdentifier: 'CONTAINER',
         apiToken: 'TOKEN',
         environment: 'development'
     }]
  });

  var container = CloudKit.getDefaultContainer();
  var database = container.publicCloudDatabase; 

  container.setUpAuth()
    .then(function(userInfo){
      publicDB.performQuery({recordType:'Schedule'}).then(function(response){
         console.log(response);
    }).catch(function(error){
      console.log(error);
    })    
 })();
