login() fails with any user password combination.

[charrondev]

I am trying to sign in as the admin user I created. I want to avoid the window popup so I am passing in the Authorization header, and that seems to be working properly, but when I call the login function

const user = {
      name: 'admin',
      password: 'password'
    }

    const pouchOpts = {
      skipSetup: true
    }

    const ajaxOpts = {
      ajax: {
        headers: {
          Authorization: 'Basic ' + window.btoa(user.name + ':' + user.password)
        }
      }
    }

    console.log(ajaxOpts)

    const db = new PouchDB(`http://localhost:5984/example`, pouchOpts)
    db.login(user.name, user.password, ajaxOpts).then((res) => {
    })

It throws an error saying that the authorization is invalid. It can't be invalid because it authorized access through the header, but it throws the following error on the server:

[error] [<0.135.0>] httpd 500 error response:
 {"error":"badmatch","reason":"{\"name\":\"admin\",\"password\":\"password\"}"}

I'm using CouchDB 1.6.1.

If I manually do the authorization using Postman, or an ajax library it seems to work properly though.

So I've gotten it to work. The issue seems to be in lib/index.js when you JSON encode the username and password. body : JSON.stringify({name: username, password: password})

If I pass options:

const ajaxOpts = {
  ajax: {
    headers: {
      Authorization: 'Basic ' + window.btoa('admin:password')
    },
    body: {
      name: 'admin',
      password: 'password'
    }
  }
}

into login() then it works properly, because it overrides whatever weird thing goes on in the json encoding. It's quite odd to be honest. Is there a particular reason why this library JSON encodes the body, when it already gets json encoded in pouchdb-ajax?

I made a project that reproduce this issue.

I also have this issue, with a caveat - it only fails when run on the server side, not the client side.

I've created a user in _user of username "guest", password "guest"

when I run db.login('guest','guest') on client side (chrome), works fine.
when I run db.login('guest','guest') within my node.js server code, I get the same error as in this thread.

Similar to Charrondev, the following ajax fixes the problem for me on the server code: (sorry don't know how to format for the wiki)

const ajaxOpts = { ajax: { body: { name: 'guest', password: 'guest' } } }

And my error message:
{ error: 'badmatch', reason: '{"name":"guest","password":"guest"}', name: 'badmatch', status: 500, message: '{"name":"guest","password":"guest"}' }

Sorry that I haven't been able to get into this recently, even though I opened the issue. If it works in the browser and not node, that makes sense for my situation, as I am using Electron, which straddles the line between the two.

Any chance we can get that working for Node.js? I'm having the same issue...

Fixed by 5b61b00.

The error I am getting is Uncaught TypeError: this.remote.login is not a function - is that the same error you were getting? (I am still getting the error even though I have applied the fix.)(5b61b00)

[ptitjes]

@vogelbeere, no this is a different problem:
There is another problem with using pouchdb-authentication on Node.js, coming from a pouchdb-ajax bug. This bug have been fixed in pouchdb's master branch (see pouchdb/pouchdb#6814).

We are waiting for the next (coming soon) release of pouchdb to bump this dependency in pouchdb-authentication. Then you'll have a fully working stack in Node.js.

In the mean time, you can manually npm install pouchdb-ajax/master to your node_modules. But, if you want to do that in your package.json, you would have to do some postinstall script magic because pouchdb is a monorepo...

[vogelbeere]

Thanks @ptitjes - I am not using Node though.

[ptitjes]

Sorry, this issue is about some failures that happened with Node.js. So I thought this was you problem.

Would you mind opening another issue and explaining fully your problem, please ? (You'll see there is an issue template that guides you into what informations we need to help you solve your problem.)
Thank you in advance @vogelbeere.

[vogelbeere]

Sorry - I am pretty sure that my issue is not caused by the code itself, but just wanted to know what error message this issue gave rise to. I have created a StackOverflow question.

[ptitjes]

@vogelbeere If you had open an issue, that could have help others later. Also you are polluting an unrelated issue... Please, next time open an issue!

Anyway, I looked at your SO question (which I cannot answer because I don't have an SO account) and 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');

[vogelbeere]

Thanks!
