[ SOLVED ] Json parse problem
«
on:
March 23, 2023, 08:58:26 am »
Hello,
I've a json like this:
Code: Pascal
[Select]
[+]
[-]
{
"Input": [
{
"lang": {
"bg": null,
"cs": null,
"da": null,
"de": "asdasdasdasd",
"el": null,
"en": "asdasdasdasda",
"es": "anmtrodsfsad",
"et": null,
"fr": "asdasdas",
"hr": null,
"hu": null,
"it": "asda grill",
"lt": null,
"lv": null,
"nl": null,
"pl": "asdasdasd grilla",
"pt": "asdasdasda",
"ro": null,
"ru": "\u0441\u0435\u043d\u0441\u043e\u0440\u043d\u044b\u0439 \u0433\u0440\u0438\u043b\u044c",
"sk": null,
"sl": null,
"sr": null,
"sv": null,
"tr": null
}
,
"val_par"
:
1
}
]
}
I wrote a code like this :
Code: Pascal
[Select]
[+]
[-]
var
jInput
,
jVersions
:
TJSONArray
;
js
,
o
,
t
:
TJSONData
;
str
:
string
;
i
,
c
:
Integer
;
JsonFile
:
TFileStream
;
fileStream
:
TFileStream
;
tl
:
TStringList
;
stTemp
:
string
;
begin
try
tl
:
=
TStringList
.
Create
;
tl
.
LoadFromFile
(
fileJson
)
;
js
:
=
GetJSON
(
tl
.
Text
)
;
o
:
=
js
.
FindPath
(
'Input'
)
;
if
(
o <>
nil
)
and
(
o
.
JSONType
=
jtArray
)
then
begin
jInput
:
=
TJSONArray
(
o
)
;
for
i
:
=
0
to
jInput
.
Count
-
1
do
begin
o
:
=
jInput
[
i
]
.
FindPath
(
'lang'
)
;
if
(
o <>
nil
)
and
(
o
.
JSONType
=
jtObject
)
then
begin
end
;
end
;
end
;
finally
js
.
Free
;
tl
.
Free
;
end
;
end
;
I don't understand how to reach language tags like "bg", "cs", etc...
Thanks in advance.
