REST API Base64映像imagecreatefromstring():数据不是可识别的格式

标签: php json base64 gd

我正在为Android应用开发REST API。我想将base64图像另存为从应用程序发送的jpeg图像。我在laravel干预下为此编写了代码,并与邮递员进行了测试。没问题。但是,当从Android应用发送数据时,他们说我收到了一条错误消息Image intervention - Image source not readable,出现了500条错误。

之后,我看到他们的JSON包含反斜杠和\n。所以我试图用stripslashesstripcslashesutf8_encodeutf8_decode来逃避他们,但是没有运气。

我离开了laravel干预并开始尝试使用imagecreatefromstring(gd)库。也没有imagecreatefromstring(): Data is not in a recognized format消息带来的好运。

这是我的尝试。

$data = json_decode($json_string);

var_dump($data->image);
// After copy and pasted the var_dump result to the postman it works

$base64_decoded = base64_decode($data->image);

imagecreatefromstring($base64_decoded);
?>

您使用Base64编码的数据实际上是.webp图像,但是imagecreatefromstring()函数未检测到这种编码。

更改:

imagecreatefromstring(

imagecreatefromwebp(
