Hi,
If I get a photo from IOS camera, and store it in a variable named IMG_profile, and I would like to upload it to a http server which is running PHP, how can I do it with HTTPRequest?
Or there is other methods?
Thank you in advance

In android I use a webservice. I encode the image with base64 and serverside I decode the string and save the image. |

Hi Richard,
you need to have a php page able to receive your image (I don't do php,
so that one is on you)
- you need to convert the image into a string to send it (base64
encoding, by example, or simply buffertohexa) on the IOS side
- you need to decode it on the php side.
depending on the side of the image, you may also have to do all that in
POST mode instead of get (get is limited in the parameters size)
There is an example of all that in WXReplication, but not with a php
page, with an awp one
Best regards

Hi, KJVA and Fabrice,
Thank you so much for your replies, I have successfully encoded the image in Base64, but I found HTTPRequest post method is not supported in WinDev Mobile, so I couldn't get the post parameters at my server side. I have also tried HTTPSendForm function, and got the same result.
P.S. I set the Content-type to "multipart/form-data", I did this successfully by using POSTMAN(a Restful client).
@KJVA what function do you use? GET in HTTPRequest or HTTPSendForm?

I use the webservice functionality in WindevMobile. I implemented a webservice in netbeans and deployed that to a tomcat server. I added the wsdl to my windevmobile project.
aImage is wsKAMapp.sendImage
aImageResult is wsKAMapp.sendImageResponse
aImage.bestand = Crypt(Bestand.foto,"",cryptNone)
aImage.bestandID = nBestandID_ws
aImageResult = wsKAMapp.sendImage(aImage)
wsKAMapp is the name of my webservice
sendImage is a method of my webservice, it expects a base64 encoded string and an ID integer
Bestand.foto is my image
for use of a webservice you can check the windev helpdocuments |

Hi, KJVA,
I did some research the help documents on web service, but it seems it doesn't work in my case. The service I have done is using JSON instead of SOAP(XML?). So is your web service SOAP?Meanwhile, I have looked into the docs for JSON service support, I couldn't find it. WinDev Mobile doesn't well support json, I suppose. |

I finally found a solution.
For those who too looks for it, I post it here.
Instead of using HTTPRequst(), I use HTTPSendForm(). If you cannot receive the post variables on the server side, please convert it to ANSI by using UnicodeToAnsi()
Example code:
HTTPCreateForm("FORM")
HTTPAddParameter("FORM", "name", UnicodeToAnsi("John"))
HTTPAddFile("FORM", "photo", IMG_Photo)
IF HTTPSendForm("FORM", sRequestUrl) THEN
bufResponse is Buffer = HTTPGetResult()
jz is Variant =JSONToVariant(bufResponse)
ELSE
Error(ErrorInfo())
END
On the server side you, PHP can get the file in $_FILE
Hope this help.
Regards,
Richard |
