打开Goog​​le云端硬盘选择器时出现错误-您所请求的功能当前不可用。请稍后再试

Question

我一直在尝试找出与我的Google Drive Picker集成不正确的地方，但未能做到。

选择器打开后，将显示“登录”屏幕，然后将首次打开OAuth流程。完成后，它将再次重复“登录”屏幕。这次再次单击它时，显示错误-“您请求的功能当前不可用。请稍后再试。”

我尝试搜索各种答案，但没有一个奏效。我已经尝试在选择器初始化之前添加OAuth流，但仍然不能解决问题。任何帮助将不胜感激。

import { h, Component } from 'preact';
import googleClientAPI from 'google-client-api';
import styles from 'stylesheets/components/commons/drive';
import config from '../../config';

export default class DriveFilePicker extends Component {
  constructor(props) {
    super(props);
    this.setState({
      loaded: false,
    });
  }

  componentWillMount() {
    googleClientAPI().then(gapi => {      
      gapi.load('picker', this.buildPicker);      
    });
  }

  handleAuthResult = (authResult) => {
    if (authResult && !authResult.error) {
      oauthToken = authResult.access_token;
      this.buildPicker(oauthToken);
    }
  }


  buildPicker = (accessToken) => {
    accessToken = accessToken || this.props.accessToken;
    if (typeof google !== 'undefined' && typeof accessToken !== 'undefined') {
      const docsView = new google.picker.DocsView()
        .setIncludeFolders(true)
        .setMimeTypes('application/vnd.google-apps.folder')
        .setSelectFolderEnabled(true);

      this.picker = new google.picker.PickerBuilder()
        .enableFeature(google.picker.Feature.MULTISELECT_ENABLED)
        .addView(docsView)
        .setOAuthToken(accessToken)
        .setDeveloperKey(config.gapi.developerKey)
        .setCallback(this.onPicked)
        .build();
      this.setState({
        loaded: true,
      });
    }
  }

  componentWillReceiveProps({ accessToken: nextAccessToken }) {
    if (this.props.accessToken !== nextAccessToken) {
      this.setState({
        loaded: false,
      });
      this.buildPicker(nextAccessToken);
    }
  }

  onPicked = ({ action, docs }) => {
    if (action === 'picked') {
      this.props.onAddFolder(docs);
    }
  }

  onOpen() {
    this.state.loaded && this.picker.setVisible(true);
  }

  render() {
    const { loaded } = this.state;
    return (
      <div className={`${!loaded ? styles.disabled : ''} ${styles.drive}`}>
        <div className={styles.label}>Sync folders</div>
        <div className={`${!loaded ? styles.disabled : ''} ${styles.folders}`}>
          <Tag hideRemove={true} onClick={::this.onOpen}>+Add folder</Tag>
        </div>
      </div>

最后获得了这一系列函数来加载api platform和client，我在<script src/>中也有index.html，但是我认为那不是安装后appendChild script时需要。将api加载到platform到client:auth2，然后从picker成功authResult构建authorize的顺序似乎很重要。我无法使用sign-in2 + init，所以我使用了authorize

var SCOPES = "https://www.googleapis.com/auth/drive.file"
...
componentDidMount = () => {
this.loadGoogleAPI()
}

加载Google脚本

  loadGoogleApi() {
    const script = document.createElement("script");
    script.src = "https://apis.google.com/js/api.js";
    script.onload = () => {
      console.log("google api loaded");
      this.loadGapi();
    };
    document.body.appendChild(script);
  }
  loadGapi = () => {
    const script = document.createElement("script");
    script.src = "https://apis.google.com/js/platform.js";
    script.onload = () => {
      console.log("google api platform loaded");
      this.loadGapiClient();
    };
    document.body.appendChild(script);
  };

  loadGapiClient = () => {
    const script = document.createElement("script");
    script.src = "https://apis.google.com/js/client.js";
    script.onload = () => {
      console.log("google api client loaded");
      /*this.gapi.client.load("youtube", "v3", () =>
        console.log("loaded youtube")
      );*/
      this.gapi = window.gapi;
      this.gapi.load("client:auth2", () => {
        /*this.gapi.load("signin2", () => {
            console.log("render a sign in button");
            // using this method will show Signed In if the user is already signed in
          });*/
        console.log("auth2 loaded");
      });
    };
    document.body.appendChild(script);
  };

点击了Google品牌的登录按钮

  loadGapiApi = () => {
    //var DIALOG_DIMENSIONS = { width: "90%", height: "90%" };
    this.gapi = window.gapi;

    console.log("authooo");
    this.gapi.auth2.authorize(
      //getAuthInstance().signIn(
      //init(
      //authorize(
      {
        api_key: API_KEY,
        client_id: CLIENT_ID,
        scope: SCOPES,
        prompt: "none"
        //prompt: "select_account"
      },
      (authResult) => {
        if (authResult) {
          this.gapi.client.load("drive", "v3", () =>
            console.log("loaded drive")
          );

          this.gapi.load("picker", () => {
            console.log("drive picker loaded");
            this.googlepicker = window.google;

            var view1 = new this.googlepicker.picker.DocsView(
              this.googlepicker.picker.ViewId.IMAGE
            ).setSelectFolderEnabled(true);


            var view = new this.googlepicker.picker.DocsView(
              this.googlepicker.picker.ViewId.DOCS
            ).setSelectFolderEnabled(true);
            var uploadView = new this.googlepicker.picker.DocsUploadView();
            view.setMode(this.googlepicker.picker.DocsViewMode.LIST);
            view.setQuery(window.dataFeedName);

            this.picker = new this.googlepicker.picker.PickerBuilder()
              .setAppId(CLIENT_ID)
              .setOAuthToken(authResult.access_token)
              .addView(view)
              .addView(uploadView)
              //.enableFeature(google.picker.Feature.SIMPLE_UPLOAD_ENABLED)
              //.enableFeature(google.picker.Feature.SUPPORT_TEAM_DRIVES)
              .enableFeature(
                this.googlepicker.picker.Feature.MULTISELECT_ENABLED
              ) //optional
              .setOrigin("https://thumbprint.us")
              .setCallback(this.pickerCallback)
              .build();
            window.picker = this.picker;

          });

          this.gapi.load("drive-share", () => {
            console.log("share dialog loaded");
            this.s = window.s;
            this.s = new window.gapi.drive.share.ShareClient();
            this.s.setOAuthToken(authResult.access_token);
          });

          this.setState({
            authResult,
            accessToken: authResult.access_token,
            authorizedScopes: true,
            signedIn: true
          });
          //const auth2 = this.gapi.auth2.getAuthInstance();
          //this.auth2.signIn();
        }
      }
    );
  };

共享驱动器和注销
