Why parenthesis is needed in this Coffeescript? - coffeescript

I have this piece of code
#_showSection(
{ redirect: url, token: token },
FailedView)
In Coffeescript, parenthesis is optional, so I tried to remove them
#_showSection
{ redirect: url, token: token },
FailedView
I got a SyntaxError: unexpected INDENT
I tried a few other changes e.g.
#_showSection
redirect: url, token: token
FailedView
They are not accepted by coffeescript compiler either.
Why in this case the removal of parenthesis is not acceptable?

This works fine for me:
#_showsection
redirect: url, token: token
FailedView
And your indentation is wrong in the second example. You also can put the key/value pairs each on one line.
#_showsection
redirect: url
token: token
FailedView
What doesn't work, is putting the object argument on its own line with braces.
Edit:
If you want a solution with braces, you could go with something like this:
#_showsection {
redirect: url,
token: token
},
FailedView
Also, if you want all the extras, you can use the shortened syntax for object description (if you use braces):
#_showsection {
redirect: url,
token},
FailedView
I still couldn't find one where the first argument starts on the second line with a brace.

POST http://127.0.0.1:8000/api/v1/users/ 400 (Bad Request)

I'm following a tutorial verbatim.
The following code throws up a 400 Bad Request error, with the following information:
data: undefined status: undefined statusText: undefined headers:
undefined config: undefined request: undefined
Code
if (!this.errors.length) {
const formData = {
username: this.username,
password: this.password1,
};
console.log(formData);
axios.post("/api/v1/users/", formData);
}
Console.log prints the following, so there's no issue with the data:
{username: 'code#code.com', password: 'code'}
A bit surprised as I've set up CORS and djoser exactly as in the tutorial.
This is the relevant code in urls.py:
urlpatterns = [
path('admin/', admin.site.urls),
path('api/v1/', include('djoser.urls')),
path('api/v1/', include('djoser.urls.authtoken')),
]
I'm able to go to http://127.0.0.1:8000/api/v1/users/ and view and post via my browser, so the issue must be with axios, but I'm not sure what it is. Any thoughts?
I realised that I'm getting this error when I input (dummy) passwords that are either short (e.g., 4 letters) or look too similar to the username input. For example, "something#something.com" with password "something" will throw up this error, but more sophisticated passwords won't.

Flutter/Dart Uri not escaping colon or slash "https://" in params

Is there a way to escape colon and forward slash in params?
Uri.https('example.com', '/api', {
'response_type': 'code',
'client_id': 'id',
'redirect_uri': 'https://www.google.com',
})
The above turns into this: https%3A%2F%2Fwww.google.com
Encoding doesn't work
final redirect = Uri.encodeFull('https://www.google.com');
final uri = Uri.https('example.com', '/api', {'redirect_uri': redirect});
print(redirect); // https://www.google.com
print(uri.query); // redirect_uri=https%3A%2F%2Fwww.google.com
Anything you give to that function is urlencoded, because HTTP.
It seems you need to urldecode it before you use it in your scenario. This should help https://stackoverflow.com/a/17407240/679553
Here's how to decode a URLEncoded string
print(Uri.decodeFull(uri.query));

Escape " in axios

I am making an api call to WuFoo forms
to do a dateCreated filter it needs to look like this (note double quote):
Filter1=DateCreated+Is_greater_than+"2019-11-13 12:00:00"
However, Axios urlencodes it to look like this:
Filter1=DateCreated%2BIs_greater_than%2B%222019-11-13+12:00:00%22'
and WuFoo unfortunately returns incorrect response to that.
I have tried escaping the encoding by using paramSerializer:
const instance = axios.create({
baseURL: 'https://subdomain.wufoo.com/api/v3',
timeout: 1000,
headers: { 'Authorization': 'Basic fjdkalfjkdafldklaskflsdkl' },
paramsSerializer: function(params) { return params }
});
....
instance.get('/forms/form/entries.json',{
params:{
Filter1: qDateFilter
}
})
qDateFilter = DateCreated+Is_greater_than+"2019-11-13 12:00:00"
However I now have the following error:
TypeError [ERR_UNESCAPED_CHARACTERS]: Request path contains unescaped characters

at processTicksAndRejections (internal/process/task_queues.js:93:5) {
code: 'ERR_UNESCAPED_CHARACTERS'
}
Attempts to just use a straight full string as a URL don't work either, it still encodes it.
Using straight " in postman works fine, same with curl.
Any other options?
WuFoo got back to me. It wasn't the " it was actually the encoding of the + sign. I replaced with spaces and it worked.

Trying to use 'Postman' and having trouble setting Basic access authentication Headers

I have an API endpoint that I am trying to test with the google app: 'Postman'. I need to set the headers which use 'Basic authentication'. I am not sure what should go in 'Header: Value'
This is how the admin said the headers should be set:
"The head value is the word 'Basic' followed by your org name and your Api key separated by a colon and base64 encoded."
I have tried numerous things but I am not getting it quite right. The error I get is "Message: Token not set".
Your header field should look like this:
Header : Authorization
Value : Basic base64('YourOrgName:YourAPIKEY');
You can get the base64 value of your string here:
https://www.base64encode.org/
For example, for my-org-name:123key4api it should be bXktb3JnLW5hbWU6MTIza2V5NGFwaQ==.
The complete header would look like:
Authorization: Basic bXktb3JnLW5hbWU6MTIza2V5NGFwaQ==
Looks like you are facing trouble in getting the base64 value. Well you can make use of in-built function in Javscript as below.
Simply run below code in any JS runtime, (Simplest would be - open console tab in chrome developer tool)
"username:password!" // Here I used basic Auth string format
// Encode the plain string to base64
btoa("username:password!"); // output: "dXNlcm5hbWU6cGFzc3dvcmQh"
// Decode the base64 to plain string
atob("dXNlcm5hbWU6cGFzc3dvcmQh"); // output: "username:password!"
It's 2019 and with Version 6.5.3 we have a separate tab to use different kind of Authentication techniques.
For basic auth you just have to give username and password after selecting "Basic Auth" under Authentication tab
Putting it all together in a pre-request script

MVC + Extjs + IIS6 + Wildcard Mapping = Post Form resulting in 302 object moved

Everything seems to work fine until i want to submit the form and update the database.
Wildcard mapping works on requests like "/navigation/edit/1", but when i submit the form as:
var ajaxPost = function(Url, Params) {
Ext.Ajax.request({
url: Url,
params: Params,
method: 'POST',
async: false,
scope: this
});
};
it says "200 bad response: syntax error" and in firebug there is "Failed to load source for: http://.../Navigation/edit/1".
Any help?
Perhaps its a syntax error: try
params: {"sendparams": Params}
it turns out there was a urlrewrite rule for some other web site corrupting my requests.
