I have two JSON returns.
One I am able to parse fine
{"login"=>"foo", "id"=>bar,
with
#foobar_collect["login"]
But one I am having issues with
{"items"=>[{"user_id"=>foo, "user_type"=>"bar",
I try
#foobar_collect["items"]["user_id"]
And it gives me an error no implicit conversion of String into Integer
What am I doing wrong?
try
#foobar_collect['items'][0]['user_id']
The reason why your code doesn't work is #foobar_collect['items'] is an array.
#foobar_collect["items"].first["user_id"]

I'm working on a lua script to convert IO Link data into MQTT. When I debugged the script, I got following runtime error on the function client:register :
Runtime error: attempt to call a table value (global 'string')
I understood that out of the 3 parameters needed, the eventname has to be in string. Coming from Java, I tried converting it directly in the function. It looks like this:
client:register( deviceHandle, string(IOhandleOnDisconnected) , IOhandleOnDisconnected )
It still does not work though.
Does anybody have an idea how to fix this?
Greetings.
string is Lua's standard library for string manipulation. It is a Lua table which cannot be called as you did in string(IOhandleOnDisconnected)
can you help me to convert this to python 3.5 ? I tried but it don't work. I did the following steps:
I change the package md5 to hashlib
I change all the id = md5.new("%s"%str(clf.get_params())).hexdigest() to id = hashlib.md5(("%s"%str(clf.get_params())).encode('utf-8') ).hexdigest()
but I still have somme problems when I put a directory to these parameters
save_preds="",
save_params=""
save_test_only=""
clf_name="XX"
I have the folowing error when I put something in thise parameters:
TypeError: a bytes-like object is required, not 'str'
Please see the code here:
blend_proba.py
Thanks,
cdk
Replacing
clf_name="XX"
by
clf_name=b"XX"
would convert the strings into objects of type bytes. Whether those changes will be enough, I honestly have no idea.
This is the code snippet at line 461 which is giving badarg error ,please help me solve this error guys.

One of the things I like about functional languages is that you generally have an easier time reproducing errors in a controlled environment. In your case, it seems like
base64:decode(XML)
is the call that's failing, so you should write
io:format("XML=~p~n", [XML]),
base64:decode(XML)
the first line will print out the contents of XML in Erlang syntax, and the second line will fail when you get to the bad input.
Once you see the string you're trying to decode, the problem will probably be obvious (it's not a string or it's not a base64 string). If it is a correctly-encoded base64 string, then you can post that problem as a StackOverflow question and get a more useful response.
Problem with the S22.Imap:
xm003 BAD [CLIENTBUG] Command syntax error
my Search Condition from the Example:
IEnumerable<uint> uids = client.Search(SearchCondition.SentSince(new DateTime(2015, 10, 20)));
oll other SearchCondition's work fine. Pls Help.
The problem is that S22.Imap is sending an incorrectly formatted date string in the SENTSINCE search query.
Since S22.Imap is a dead project, I would recommend switching to my open source MailKit library instead.
Hope that helps.
I'm trying to load images from Flickr's API into a Ruby on Rails app, but I'm getting "Unexpected Token" on my JSON.parse() line.
I found another response here where the returned JSON had it's double quotes escaped out, and the solution was to add the .gsub thing to the end, but I'm still getting an error.
Anyone know what the problem is?
def add
#jsonresults = open("http://api.flickr.com/services/rest/?method=flickr.interestingness.getList&api_key=bb398c11934abb6d51bdd720020f6a4a&per_page=1&page=1&format=json&nojsoncallback=1").read
#images = JSON.parse(#jsonresults.to_json.gsub('\"', '"'))
end
The error:
JSON::ParserError in ImagesController#add
757: unexpected token at '"{"photos":{"page":1, "pages":500, "perpage":1, "total":500, "photo":[{"id":"8234011021", "owner":"24066605#N07", "secret":"b4c05df8c5", "server":"8341", "farm":9, "title":"Crescent Lake", "ispublic":1, "isfriend":0, "isfamily":0}]}, "stat":"ok"}"'
The json returned by the call looks fine. Change your parsing to this:
#images = JSON.parse(#jsonresults)
That is not valid JSON. The outer set of double-quotes do not belong. This is the valid version:
'{"photos":{"page":1, "pages":500, "perpage":1, "total":500, "photo":[{"id":"8234011021", "owner":"24066605#N07", "secret":"b4c05df8c5", "server":"8341", "farm":9, "title":"Crescent Lake", "ispublic":1, "isfriend":0, "isfamily":0}]}, "stat":"ok"}'
