UrlEncode, UnlDeCode (SOLVED)

[RAMESHBABU]

Dear Friends,

Can anybody please help me converting these two function as under, in FWH/XHARBOUR ?

Code: Select all  Expand view

string urlEncode(string str){
    string new_str = "";
    char c;
    int ic;
    const char* chars = str.c_str();
    char bufHex[10];
    int len = strlen(chars);

    for(int i=0;i<len;i++){
        c = chars[i];
        ic = c;
        // uncomment this if you want to encode spaces with +
        /*if (c==' ') new_str += '+';  
        else */if (isalnum(c) || c == '-' || c == '_' || c == '.' || c == '~') new_str += c;
        else {
            sprintf(bufHex,"%X",c);
            if(ic < 16)
                new_str += "%0";
            else
                new_str += "%";
            new_str += bufHex;
        }
    }
    return new_str;
 }

string urlDecode(string str){
    string ret;
    char ch;
    int i, ii, len = str.length();

    for (i=0; i < len; i++){
        if(str[i] != '%'){
            if(str[i] == '+')
                ret += ' ';
            else
                ret += str[i];
        }else{
            sscanf(str.substr(i + 1, 2).c_str(), "%x", &ii);
            ch = static_cast<char>(ii);
            ret += ch;
            i = i + 2;
        }
    }
    return ret;
}
 

Thank you in adnvace

Dear Ramesh,

Those functions are already available in Harbour, so you can copy the code to xHarbour:

https://github.com/harbour/core/blob/master/contrib/hbtip/encurlc.c

Mr.Antonio,

Thank you very much for your instant help.

Actually I am supposed to send SMS through SMS Gateway. I am able to send SMS
using the Gateway service provider's API in English. But when I try to send
in our Local Language, it recipient is getting some junk characters. Where as
If I send the same message using the Control Panel provided by Service Provider,
or if I compose the text and paste it in the Browser's address bar along with the
API's Url, the message is sent to the recipient with its intended text.

The following is the functionality I am using.

Can you kindly can help me in this context.

Dear Ramesh
Try with

Code: Select all  Expand view

   HB_SETCODEPAGE( "UTF8" )
 Fw_SetUnicode( .T. )
.../...
 

and tell me

[RAMESHBABU]

Dear Cristobal,

I have set the Code Page to "8TF8", In spite of that the message is received as under.

ప్రియమైన తల్లి తండ్రులారా, మీ విద్యార్ధి ఈ రోజు అనగా 21-09-2019 న పాఠశాలకు హాజరు కాలేదని దయచేసి గుర్తించగలరు.-ఇట్లు ప్రధాన ఉపాధ్యాయుడు.Dear Parent, Please note that your Son is absent to the School on 21-09-2019. Please ensure his regular presence. -Principal

[cnavarro]

Where can I see the information of the api that you use?

[RAMESHBABU]

Dear Cristobal,

I sent to your personal mail.

Please check it.

My best Regards,

I am using harbour, so I didn't test this code with xHarbour, but here a version without C-code of urlEncode:

Code: Select all  Expand view

//#include <xhb.ch> //for harbour compiling

proc main()
   hb_cdpSelect("UTF8")
   ? UrlEncode("ప్రియమైన తల్లి తండ్రులారా,  మీ విద్యార్ధి  ఈ రోజు అనగా 21-09-2019 న పాఠశాలకు  హాజరు కాలేదని దయచేసి గుర్తించగలరు.")
return

function UrlEncode(cInput)
   LOCAL i, cEncoded:=""
   for i:=1 to len(cInput)
      cEncoded+=toPercent(cInput[i])
   next
return cEncoded

func toPercent(v)
   LOCAL r:="%"
   if v<127 .and. !(v $ CHR(10)+CHR(13)+" !#$%&'()*+,/:;=?@[]"+'"%<>\^`{|}')
      return v
   endif
   v:=asc(v)
   // harbour compatible version
   //r+=("0123456789ABCDEF")[hb_bitand(hb_bitShift(v,-4),15)+1]
   //r+=("0123456789ABCDEF")[hb_bitand(v,15)+1]
   r+="0123456789ABCDEF"[((v >> 4) & 15)+1]
   r+="0123456789ABCDEF"[(v & 15)+1]
return r

Hi, Mr.AntonioP,

I tested your code. It is also working fine.

Thank you very much for your kind help.
