imagick无法对远程url图片进行编辑问题

Jun 06, 2016 pm 08:29 PM
exception imagick php url

<code><?php header("content-type: image/png");
$handle = fopen('http://i3.tietuku.com/2afd667e3eded5e0.png', 'rb');
$img = new Imagick();
$img->readImageFile($handle);
$img->resizeImage(128, 128, 0, 0);

echo $img;
</code>
Copy after login
Copy after login

大家看我的这段代码,我是按照php官方文档的示例代码写的代码,理论上代码质量是有保障的,但是我还是报出了错误:

<code>( ! ) Fatal error: Uncaught exception 'ImagickException' with message 'Unable to read image from the filehandle' in D:\wampServer\www\test\index.php on line 5
( ! ) ImagickException: Unable to read image from the filehandle in D:\wampServer\www\test\index.php on line 5
Call Stack
#	Time	Memory	Function	Location
1	0.0000	139136	{main}( )	..\index.php:0
2	0.0700	150424	readimagefile ( )	..\index.php:5</code>
Copy after login
Copy after login

我在本地测试是没问题的,可以用 绝对路径 打开图片,进行正常的图片操作。
下面是环境展示:
