Google App Engine上的CouchDB登录访问 [英] CouchDB login access on Google App Engine

问题描述

我正在Google App Engine上运行一个CouchDB实例.我已经成功创建了SSH隧道来访问Fauxton通过本地主机.我已启用CORS，并且正在使用https.我已经添加了NETWORK: *到我的缓存清单中.

I am running a CouchDB instance on Google App Engine. I have successfully created a SSH tunnel to access Fauxton on it via localhost. I have enabled CORS and am using https. I have added NETWORK: * to my cache manifest.

现在，我需要将PouchDB数据同步到远程CouchDB数据库.

Now I need to sync my PouchDB data to my remote CouchDB database.

此相关问题使用用户名和密码的Couchdb同步访问显示如何在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.)

This related question Couchdb sync access with userid and password shows how to pass in the userid and password on a CouchDB instance hosted on cloudant. (I've also checked all the other related questions.)

在Google App Engine上可以使用类似的方法吗?

像这样吗?

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

根据 PouchDB:入门，格式为http://user:[e-mail]/dbname

我不确定是否应该使用主机名(myapp.appspot.com)或主机的IP地址.

I'm not sure if I should use the hostname (myapp.appspot.com) or the host's IP address though.

Code in application.js

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

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


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

控制台中的错误消息

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

推荐答案

感谢

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

您正在尝试在字符串上调用login()(您的this.remote是一个 细绳).因此，TypeError: this.remote.login is not a function.你 应该做的:this.remote = new PouchDB(remoteorigin + '/myPdb');

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');

(我发现这很令人困惑，因为远程数据库是CouchDB，但是您就可以了.)

(I find that confusing because the remote database is CouchDB, but there you go.)

登录现在可以正常工作，但同步仍然无法正常工作.

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