strange backslash when json.write - Hadeel - 08.08.2022
Hi !
I am working on LM app development and below is the index.lp code.
From the commandline I can use the endpoint like this , with a request body. It returns the result like this : {"results":[{"alias":"6\/6\/1","value":true}]}
Is there a way to remove the backslash in from the result json string ?
Thank you !
http://id:pass@LM local IP/apps/data/logic-machine/index.lp
{
"commands":[
{
"alias":"6/6/1",
"value":true
}
]
}
Code:
<?
require('json')
require('apps')
params = ngx.req.get_body_data()
params = json.pdecode(params)
require('custom.utils')
results = {}
if params ~= nil then
for index, command in ipairs(params.commands) do
if type(command.alias) ~= nil or type(command.value) ~= nil then
res = grp.write(command.alias, command.value) or false
table.insert(results, {value = res, alias = command.alias})
end
end
results = {
results = results
}
write(json.encode(results))
end

No need to remove this backslashes. This is allowed by the JSON specification. Some libraries escape forward slashes and some do not.

Thank you admin for your help always !
Oh I understand ... my client want them without backslashes....
Is there any way not to escape this ?
Or maybe I need to ask them to unescape them when they decode json ?

What programming language/library is your client using? Nearly all of them can handle such escape sequence.

Thank you admin! I think it's Go lang
RE: strange backslash when json.write - admin - 09.08.2022
Go JSON parser will handle it correctly.
Escaping slashes can be removed like this but it's a pointless operation
Code:
results = json.encode(results)
results = results:gsub('\\/', '/')
write(results)RE: strange backslash when json.write - Hadeel - 10.08.2022
Thank you admin !!
I will talk with my client about this (:
Your solution worked also !
