From Smalltalk to JavaScript

window btoa: 'usr:pwd'

Hi Richard,

not knowing if your code would work, I would still think you have to change your assignments from "=" to ":="

jQuery := JQuery current.

jQuery getJSON: 'some-url'

    beforeSend: [:xhr | |enc| enc := window btoa: 'usr:pwd'.

        xhr setRequestHeader: 'Authorization' put: 'Basic ',enc]

    onSuccess: [:jsonData | "do something with jsonData"].

I can use jQuery's beforeSend callback to add a HTTP header with authentication information:

beforeSend: function (xhr) {

    xhr.setRequestHeader ("Authorization", "Basic XXXXXX");

},

So in my Amber code, I tried this:

jQuery = JQuery current.

jQuery getJSON: 'some-url'

    beforeSend: [:xhr | |enc| enc = window btoa: 'usr:pwd'.

        xhr setRequestHeader: 'Authorization' put: 'Basic ',enc]

    onSuccess: [:jsonData | "do something with jsonData"].

It does not understand btoa:,  even though the following works perfectly in the Workspace:

window btoa: 'usr:pwd'

When I get rid of the btoa stuff, it complains that it does not understand setRequestHeader:.

I've looked at this: <a href="https://github.com/amber-smalltalk/amber/wiki/From-smalltalk-to-javascript-and-back" target="_blank" rel="nofollow" onmousedown="this.href='https://www.google.com/url?q\75https%3A%2F%2Fgithub.com%2Famber-smalltalk%2Famber%2Fwiki%2FFrom-smalltalk-to-javascript-and-back\46sa\75D\46sntz\0751\46usg\75AFQjCNFEoAvzKjJ20Ozb5129ypzW2j5ZSw';return true;" onclick="this.href='https://www.google.com/url?q\75https%3A%2F%2Fgithub.com%2Famber-smalltalk%2Famber%2Fwiki%2FFrom-smalltalk-to-javascript-and-back\46sa\75D\46sntz\0751\46usg\75AFQjCNFEoAvzKjJ20Ozb5129ypzW2j5ZSw';return true;">https://github.com/amber-smalltalk/amber/wiki/From-smalltalk-to-javascript-and-back

As for `window btoa: 'foo'`, it is preferable not to use `window` to access globals, but instead use them directly as in `btoa value: 'foo'`.

As already mentioned, there was wrong assignment in your code (I would not use assignment at all and write `JQuery current foo: 'bar'`, but it's just my preference).

Otherwise, there should be no problems with using JS calls - though for simplicity I always used single-arg ajax: #{ 'url' -> 'baz'. ... } send (and instead of setting callbacks in options, which is IIRC deprecated, I used done: and friends on the result of ajax: send).

Hmmm.....

I jjust read that getJson is a shorthand and one can't set additional options...

Did you already consider to do it this way?
----------------------------------
get: aUrlString  do: aBlock onError: errorBlock

    jQuery ajax: aUrlString 
        options: #{
            'type' -> 'GET'.
            'contentType' -> 'application/json'.
            'beforeSend' -> [:xhr | |enc| enc = window btoa: 'usr:pwd'.

        xhr setRequestHeader: 'Authorization' with: 'Basic ',enc].

            'complete' -> [:res |
                    res status = 200
                        ifTrue: [aBlock value: res responseText]
                        ifFalse: [errorBlock value: res responseText]
}
---------------------------------------

or something like:

 jQuery = JQuery current.

 jQuery ajaxSetup: #{
        'headers' -> #{
            'Authorization' : 'Basic faskd52352rwfsdfs';
        }
    }.

 jQuery getJSON: 'some-url'

    onSuccess: [:jsonData | "do something with jsonData"].

Just guessing the seperators, I still struggle with the right Array {} syntax.

done, fail, always. Look up jQuery.ajax docs page.

Yes, from this it is clear that you do not understand how to rewrite JS call to ST message send and you just copied getJSON:onSuccess: from the example without understanding it.

You really must understand how it is done, or these questions never end. Try to reread that wiki page until you get it (onSuccess: is totally unimportant. You can write froznicate:, foobar: or whatever else there; see how keyword message for multiple-arg calls are created
 and how other keywords beyond the first are not used at all beyond the fact that it separates second parameter from the first).
