[WM26] - HTTPGetResult() issues

Hi All

I've been developing an app and testing under Android. All working fine. Now I want to test under iOS. One of the immediate problems I am hitting is with the HTTPGetResult() function. The app makes a call to my server using HTTPRequest() and the server receives a valid request and sends back a reply. Server-side all working fine.

Now in the app I always get what appears to be an empty string. I understand the string coming back from the server must be ANSI String as the server is Windows. So I have tried to receive the string into an ANSI STRING variable and then convert the ANSI STRING variable to a UNICODE variable. But nothing seems to work - the result is always an empty string. e.g. I have tried this:

bufSServer_Response_Ansi_Buffer is Buffer = HTTPGetResult()
bufSServer_Response_Unicode_Buffer is Buffer = bufSServer_Response_Ansi_Buffer.AnsiToUnicode()

Both variables however seem to be empty.

If I check the HTTPHeader of the returned packet it says:

HTTP/1.1 200 OK
Cache-Control: private
Content-Type: text/html
Server: Microsoft 118
Date...
Conneciton:Close
Content-Length: 0

Any suggestions?

Thanks

If I remember correctly, for iOS, you need to do some magic with UTF8, not ansi/unicode...

I know that all that is detailed in several thread in the french pcsoft forum, so you should find the details there

Thanks again, Argus. Sadly I dont read French ...

perhaps, but you can search for iOS httprequest in the mobile forum, and use google translate for the reading part

Hi Argus

I searched for ios HTTPRequest() as you suggested and found the below message suggested :

[forum.pcsoft.fr]

A user has created a procedure to handle the conversion as follows:

Procedure WS_Android_IOS_HTTPGetResult()

// Variable
bufResHTTP is Buffer
sHTTPResult is string

// Retrieves the result of the query
bufResHTTP = HTTPGetResult( httpResult )

// Result in UTF8 em iOS Apple
IF IniOSMode() = True OR IniOSSimulatorMode() = True OR IniOSEmulatorMode() = True THEN

IF StringCount( bufResHTTP , “ISO-8859-1” , IgnoreCase ) = 0 THEN

sHTTPResult = UTF8ToString( bufResHTTP )

ELSE

sHTTPResult = AnsiToUnicode( bufResHTTP )

END

ELSE IF InAndroidMode() = True OR InAndroidSimulatorMode() = True OR InAndroidEmulatorMode() = True THEN

// Result in Android
sHTTPResult = bufResHTTP

END

RESULT( sHTTPResult )


However, I have tried this and all variations fail. i.e. whether I convert the HTTPResult using UTF8ToString() or using AnsiToUnicode() or just take the result as returned I still get what appears to be an empty string when testing on the iPhone. Under the emulator it works fine.

Hi JP,

>Thanks again, Argus. Sadly I dont read French ...

me too. But you can use Google Chrome with the live translate options (french->english) and you can read the forum like this here. Works like a charm.

Thanks Michael. Yes I am trying that now but cannot find a solution. Found 1 message when searching iOS HTTPRequest but the solution offered does not seem to work for me.

[SOLVED]

The WIndows server is returning some content as an ANSI string. All that is required is to receive that content into a ANSI STRING in WinDev Mobile. However, the fault was that the script returning the content did not have a content-type header excplcitly stating that the content was charset=windows-1252. Once this was added the iOS WM app understood the content and could process it.

Thanks
