Google App Engine 上的 CouchDB 登录访问

Question

我是运行 Google App Engine 上的 CouchDB 实例。我已经成功 . I have enabled CORS and am using https. I have added NETWORK: * to my cache manifest.

现在我需要将我的 PouchDB 数据同步到我的远程 CouchDB 数据库。

这个相关问题 Couchdb sync access with userid and password 展示了如何在 cloudant 上托管的 CouchDB 实例上传递用户 ID 和密码。（我还检查了所有其他相关问题。）

是否有类似的方法可以在 Google App Engine 上执行此操作？

是这样的吗？

https://<api_key>:<key_passwd>@<username>.<my_ip_address>:5984/<db_name>

根据 PouchDB: getting started 格式为 http://user:pass@myname.example.com/dbname

不过我不确定是应该使用主机名 (myapp.appspot.com) 还是主机的 IP 地址。

application.js

中的代码

PouchNotesObj = function (databasename, remoteorigin) {
    'use strict';

    Object.defineProperty(this, 'pdb', {writable: true});
    Object.defineProperty(this, 'remote', {writable: true});
    Object.defineProperty(this, 'formobject', {writable: true});
    Object.defineProperty(this, 'notetable', {writable: true});
    Object.defineProperty(this, 'searchformobject', {writable: true});
    Object.defineProperty(this, 'errordialog', {writable: true});
    Object.defineProperty(this, 'dbname', {writable: true});

    var databasename = 'myPdb';
    var remoteorigin = 'https://<IP ADDRESS>';


    this.dbname = databasename;
    this.pdb = new PouchDB(databasename);
    this.remote = remoteorigin + '/myPdb';

//from https://github.com/pouchdb-community/pouchdb-authentication/issues/121      
    var user = {
      name: 'admin',
      password: '<myPassword>'
    };
    var pouchOpts = {
      skipSetup: true
    };
    var ajaxOpts = {
      ajax: {
        headers: {
          Authorization: 'Basic ' + window.btoa(user.name + ':' + user.password)
        }
      }
    };
    this.remote.login(user.name, user.password, ajaxOpts).then(function() {
      return db.allDocs();
    }).then(function(docs) {
      console.log(docs);
    }).catch(function(error) {
      console.error(error);
    });

};

pouchdb.authentication.js

exports.login = utils.toPromise(function (username, password, opts, callback) {
  var db = this;
  if (typeof callback === 'undefined') {
    callback = opts;
    opts = {};
  }
  if (['http', 'https'].indexOf(db.type()) === -1) {
    return callback(new AuthError('this plugin only works for the http/https adapter'));
  }

  if (!username) {
    return callback(new AuthError('you must provide a username'));
  } else if (!password) {
    return callback(new AuthError('you must provide a password'));
  }

  var ajaxOpts = utils.extend(true, {
    method : 'POST',
    url : utils.getSessionUrl(db),
    headers : {'Content-Type': 'application/json'},
    body : {name: username, password: password}
  }, opts.ajax || {});
  utils.ajax(ajaxOpts, wrapError(callback));
});

控制台中的错误消息

Uncaught TypeError: this.remote.login is not a function

感谢ptitjes on Github for an answer on what was going wrong with the login() function:

you are trying to call login() on a string (your this.remote is a string). Hence the TypeError: this.remote.login is not a function. You should have done: this.remote = new PouchDB(remoteorigin + '/myPdb');

（我发现这很混乱，因为远程数据库是 CouchDB，但你知道了。）

登录正常，但同步仍然无效。

var opts = {live: true};
this.pdb.replicate.to(this.remote, opts);
this.pdb.replicate.from(this.remote, opts);
