PHP Server Android Client
I need to encode the verification code image generated by the server into base64
Note:does not generate and display images, but directly encodes the generated image resources into base64
so how to do? ? ? ? ? ? ?
闭关修行中......
Main functions:
function base64EncodeImage ($image_file) { $base64_image = ''; $image_info = getimagesize($image_file); $image_data = fread(fopen($image_file, 'r'), filesize($image_file)); $base64_image = 'data:' . $image_info['mime'] . ';base64,' . chunk_split(base64_encode($image_data)); return $base64_image; }
demo:
'; echo ''; function base64EncodeImage ($image_file) { $base64_image = ''; $image_info = getimagesize($image_file); $image_data = fread(fopen($image_file, 'r'), filesize($image_file)); $base64_image = 'data:' . $image_info['mime'] . ';base64,' . chunk_split(base64_encode($image_data)); return $base64_image; } ?>
Implementation:
================ Supplements =================
GD to base64:
ob_start (); imagejpeg ($img); $image_data = ob_get_contents (); ob_end_clean ();
It is estimated thatob_get_contentsis used to obtain buffer data.Refer to the original text: Original text link
ob_get_contents
PS:Please make good use of Google Baidu.
If the generated verification code is saved on the server side, use file_get_contents to get the image and then base64encode the result and output it.
