Your base64 string is corrupted. You can check it here: https://codebeautify.org/base64-to-image-converter
Click to expand...

here is the code in 'routes.api.php'

[CODE title="api code"]// From _GET source should be urlencoded base64
if(!G\timing_safe_compare(base64_encode(base64_decode($source)), $source)){
throw new Exception('Invalid base64 string.', 120);
}

// Set the API temp file
$api_temp_file = @tempnam(sys_get_temp_dir(), 'chvtemp');

if(!$api_temp_file or !@is_writable($api_temp_file)) {
throw new UploadException("Can't get a tempnam.", 200);
}

$fh = fopen($api_temp_file, 'w');
stream_filter_append($fh, 'convert.base64-decode', STREAM_FILTER_WRITE);
if(!@fwrite($fh, $source)) {
throw new Exception('Invalid base64 string.', 130);
} else {
// Since all the validations works with $_FILES, we're going to emulate it.
$source = array(
'name' => G\random_string(12).'.jpg',
'type' => 'image/jpeg',
'tmp_name' => $api_temp_file,
'error' => 'UPLOAD_ERR_OK',
'size' => '1'
);
}[/CODE]

If I pass the original base64 code, it will throw the exception ` throw new Exception('Invalid base64 string.', 120);`

Thank you for reply. The base64 code above is encoded.

I have read the source code, the code will decode it. And then write it to the file. So I give the encoded one.

Now I decode the encoded base64 code by `base64_decode` function, and get the code below.
