[vip-help] Need help with POST request

[Han, Yue]

Hi Andy,

I recommend you to write some debugging output in the php file to check whether the image is successfully POST to server and see the result of the base64_decode.

I think the key is checking the output of base64_decode.

You can search more for “base64_decode”, this function will return false if your upload data is not encoded in base64 format.

And if you check the Android code sending POST to this php file, you will see it is not directly sending image, it convert the bitmap to String and then send to the php.

If you want directly sending image, you don’t need “base64_decode” here, you can simply write php got to get the image/file from POST and save it without decode.

Best,
*****
