[mohammadreza hosseinzadeh]

Hi all
im a ios dev for a project that hosted with asp.net
every thing is ok but in some api that have arabic character it shown coded
when i log whole job.getstring it shows

{"msg":{"IsError":false,"Message":"","eCode":0,"StartDate":"7/23/2018 1:49:56 PM","EndDate":"7/23/2018 1:49:56 PM"},"TicketList":[{"id":28,"priorityColor":"Normal","title":"ای او اس ۱","state":"0","stateText":"ارجاع نشده","Category":"شبکه","SubmitDateTime":"1397/04/20 - 19:10"},{"id":27,"priorityColor":"Warning","title":"تست جدید","state":"0","stateText":"ارجاع نشده","Category":"اینترنت","SubmitDateTime":"1397/04/20 - 19:01"},{"id":26,"priorityColor":"Warning","title":"تست ۷","state":"0","stateText":"ارجاع نشده","Category":"نرم افزار","SubmitDateTime":"1397/04/20 - 14:08"},{"id":25,"priorityColor":"Normal","title":"تست۶","state":"0","stateText":"ارجاع نشده","Category":"تلفن","SubmitDateTime":"1397/04/20 - 14:07"},{"id":24,"priorityColor":"Danger","title":"تست ۵","state":"0","stateText":"ارجاع نشده","Category":"تلفن","SubmitDateTime":"1397/04/20 - 14:07"}]}

and everything is ok
but when i use this method

Sub JsonToMap(strJSON As String) As Map
    ' convert a json string to a map
    Dim jMap As Map
    jMap.Initialize
    Dim json As JSONParser
    json.Initialize(strJSON)
    jMap = json.NextObject
    Return jMap
End Sub

to convert my json to map
every arabic character are encoded like this

"(read only map) {\n Category = \"\\U0634\\U0628\\U06a9\\U0647\";\n SubmitDateTime = \"1397/04/20 - 19:10\";\n id = 28;\n priorityColor = Normal;\n state = 0;\n stateText = \"\\U0627\\U0631\\U062c\\U0627\\U0639 \\U0646\\U0634\\U062f\\U0647\";\n title = \"\\U0627\\U06cc \\U0627\\U0648 \\U0627\\U0633 \\U06f1\";\n}",

how can i fix this
i thought it will be fixed when i put them in label or right place but nothing happen
i dont think there is a way in basic
maybe there is a way in obj_c
but i dont know
could any one help me

After parse with JSON library,you see decoded string

 

[Erel]

You can use UnescapeUnicode to unescape it: https://www.b4x.com/android/forum/t...results-i-cant-read-hebrew.27461/#post-159533

Dim parser As JSONParser
parser.Initialize(s)
Dim m As Map = parser.NextObject
Dim list As List = m.Get("TicketList")
For Each m As Map In list
   Dim category As String = UnescapeUnicode(m.Get("Category"))
   Log(category)
Next

hi again all especially dear Erel
the code you have posted here is work correctly on array json i mean a json that contain more than one object
but wen i want use your code one a json single object i've got an error


i edit your code and made a method to easy implement my arabic characters data

Sub unscapejson (str As String,cat As String,item As String)As String()
    Dim parser As JSONParser
    parser.Initialize(str)
    Dim m As Map = parser.NextObject
    Dim list As List = m.Get(cat) 'line 152 error occur on this line
    Dim ret(list.Size) As String
    Dim i As Int=0
    For Each m As Map In list
        Dim category As String = UnescapeUnicode(m.Get(item))
        ret(i)=category
        i=i+1
    Next
    Return ret
End Sub

and here is a call of method

            Dim name() As String
            name=unscapejson(Job.GetString,"member","fname")
            Log(name(0))

but i get this error

Error occurred on line: 152 (SmsConfirm)
Expected: NSArray, object type: B4IMap
...

and its my whole json string

{"msg":{"IsError":false,"Message":"خوش آمدید.","eCode":0,"StartDate":"7/29/2018 4:34:23 PM","EndDate":null},"member":{"id":6,"key":"keykeykey123456","fname":"محمدرضا","lname":"حسین زاده","pic":"pic2"}}

tnx for your help

tnx for your help

tnx alot i fixed it when i Engage with the code

the right code for single json item is

Sub unscapejson (str As String,cat As String,item As String)As String
    Dim parser As JSONParser
    parser.Initialize(str)
    Dim m As Map = parser.NextObject
    Dim list As List 
    list.Initialize
    list.Add(m.Get(cat))
    Dim ret As String
    For Each m As Map In list
        Dim category As String = UnescapeUnicode(m.Get(item))
        ret=category
       
    Next
    Return ret
End Sub

now i have a bigger problem in this section
array in json

when i use Erel code it not work due to it is a object inside another object
let me show the json

{"msg":{"IsError":false,"Message":"","eCode":0,"StartDate":"7/29/2018 5:31:32 PM","EndDate":null},"TicketDetail":{"THead":{"id":19,"priorityColor":"warning","title":"تست اول","state":"0","stateText":"ارجاع نشده","Category":"تلفن","SubmitDateTime":"1397/04/20 - 13:58"},"Message":[{"pic":null,"Title":null,"Dif":"18 روز پیش","body":"تستی شماره اول","isSend":true,"bodyPic":""},{"pic":null,"Title":null,"Dif":"18 روز پیش","body":"درخواست شماره اول","isSend":true,"bodyPic":""},{"pic":null,"Title":null,"Dif":"18 روز پیش","body":"","isSend":true,"bodyPic":"pic3"}]}}

how can i access message objects decoded characters and ticketdetail thead obj decoded characters
