I get json string from server. Then I parser it using SBJSON library. But when I show parse results in my label I have symbols like that
!
(normally it's !).
So how can I convert my json string to normal string?
Use this: https://github.com/mwaterfall/MWFeedParser/blob/master/Classes/NSString+HTML.m (specifically, the stringByDecodingHTMLEntities method).

I am pulling a JSON formatted string from a database in some cases this string is just an array, but it badly formatted. I have no control over the data shape.
The string looks like this:
"[Hello, World]"
I want to parse this string to an array using JSON.parse, but that doesn't work when there are no quotes arround it.
So I need to somehow transform this string to this ["Hello", "World"]
Does anyone knows how the mongodb $bitsAllClear works?
I ready the document from https://docs.mongodb.com/manual/reference/operator/query/bitsAllClear/ i am trying to understand how can i create a BinData from a bitmask
For example the documentation says:
(the binary representation of BinData(0, "ID==") is 00010100.
How can i transform the 00010100 to binary to insert in the document? Is there any online converted to try?
(the binary representation of BinData(0, "ID==") is 00010100.
This example looks incorrect to me. BinData takes a base64 encoded string as its second argument, and the base64 encoding of 00010100 is FA==. Other examples on that same page look correct, so I suspect it's a typo.
In node, you can do the conversion from a binary string to base64 like so:
const hexString = parseInt('00010100', 2).toString(16);
Buffer.from(hexString, 'hex').toString("base64") // FA==

Let's say that I have following parser inside my get method:
from flask.ext.restful import reqparse
parser = reqparse.RequestParser()
parser.add_argument('when', type=datetime, help='Input wasn\'t valid!')
And then I want to test the said get method with curl...
curl --data "when=[WHAT SHOULD I WRITE HERE?]" localhost:5000/myGet
So the question is, how I should call the get method? I've tried numerous different formats, tried to read rfc228 standard, etc. but I can't figure out the right format.
Kinda late, but I've just been in the same problem, trying to parse a datetime with RequestParser, and sadly the docs are not so helpful for this scenario, so after seeing and testing RequestParser and Argument code, I think I found the problem:
When you use type=datetime in the add_argument method, under the hood it just calls datetime with the arg, like this: datetime(arg), so if your param is a string like this: 2016-07-12T23:13:3, the error will be an integer is required.
In my case, I wanted to parse a string with this format %Y-%m-%dT%H:%M:%S into a datetime object, so I thought to use something like type=datetime.strptime but as you know this method needs a format parameter, so I finally used this workaround:
parser.add_argument('date', type=lambda x: datetime.strptime(x,'%Y-%m-%dT%H:%M:%S'))
As you can see in this way you can use whatever format datetime you want. Also you can use partial functool instead of lambda to get the same result or a named function.
This workaround is in the docs.
Just an update on Flask-Restful (0.3.5): it is possible to use the own library date and datetime functionality parsing, if ISO 8601 or RFC 822 suffices:
from flask_restful import inputs
parser.add_argument('date', type=inputs.datetime_from_iso8601)
So the request would be,
curl --data "date=2012-01-01T23:30:00+02:00" localhost:5000/myGet
From the docs
I have a time string, which looks like this: 20170822T194135+00. This is called basic ISO:8601 format, if I understood correctly.
When I try to parse it using ZonedDateTime, it throws exception, complaining that it can't parse it.
SO, how do I convert this string to a valid Joda datetime object?
Do I need to build manual "format" to parse it (this would be silly, considering it's a standard format)?
Desperately, I've actually tried to implement custom format:
const time = ZonedDateTime.parse(timeString, DateTimeFormatter.ofPattern(`yyyyMMdd'T'HHmmssZ`));
But, it throws error on column 15. Looks like it fails to parse the timezone. Is my implementation correct? How do I make it work?
I could do it using the pattern x as described in the docs (this pattern accepts offsets like +00).
Then I parsed directly to a ZonedDateTime:
const formatter = DateTimeFormatter.ofPattern("yyyyMMdd'T'HHmmssx");
const time = ZonedDateTime.parse("20170822T194135+00", formatter);
The resulting time variable has the value equivalent to 2017-08-22T19:41:35Z.
The built-in formatters (such as ISO_LOCAL_DATE_TIME) can't parse this format, so the only way seems to be creating a formatter.
How can I convert Base64 encode data into hex format.
I get following data in console.
