[英]How to use imagick with php in aws lambda?
Currently Amazon lambda does supports only node.js and python. 当前,Amazon lambda确实仅支持node.js和python。 I found a official document to run php in lambda.
我找到了在lambda中运行php的官方文档。 link is https://aws.amazon.com/blogs/compute/scripting-languages-for-aws-lambda-running-php-ruby-and-go/

I have successfully ran php in lambda. 我已经在lambda中成功运行了php。 But the problem is I don't know how to use imagick with php.
但是问题是我不知道如何在php中使用imagick。 I have installed imagick on my EC2 with following commands
我已使用以下命令在EC2上安装了imagick
sudo yum install pecl make ImageMagick ImageMagick-devel php-devel gcc re2c
sudo pecl install imagick
running following command returns my imagemagick versions 运行以下命令返回我的imagemagick版本
convert --version
Outputs 输出
Version: ImageMagick 6.7.8-9 2016-06-22 Q16 http://www.imagemagick.org

I am running my php with php binaries in node.js 我正在node.js中使用php二进制文件运行我的php
process.env['PATH'] = process.env['PATH'] + ':' + process.env['LAMBDA_TASK_ROOT'];
const spawn = require('child_process').spawn;
exports.handler = function(event, context,callback) {
//var php = spawn('php',['helloLambda.php']); //local debug only
var php = spawn('php-7-bin/bin/php',['imagick.php']);
var output = "";
//send the input event json as string via STDIN to php process
php.stdin.write(JSON.stringify(event));
//close the php stream to unblock php process
php.stdin.end();
//dynamically collect php output
php.stdout.on('data', function(data) {
output+=data;
});
//react to potential errors
php.stderr.on('data', function(data) {
console.log("STDERR: "+data);
});
//finalize when php process is done.
php.on('close', function(code) {
//context.succeed(JSON.parse(output));
callback(null,output);
});
}
Above PHP is successfully running, Now I'm trying to use imagick with php by replacing var php = spawn('php-7-bin/bin/php',['imagick.php']); 上面的PHP已成功运行,现在我想通过替换var php = spawn('php-7-bin / bin / php',['imagick.php']);将imagick与php一起使用。
imagick.php imagick.php
$image = new Imagick('image.jpg');
$image->thumbnailImage(100, 0);
// Just trying to use imagick function
php.js php.js
process.env['PATH'] = process.env['PATH'] + ':' + process.env['LAMBDA_TASK_ROOT'];
const spawn = require('child_process').spawn;
exports.handler = function(event, context,callback) {
//var php = spawn('php',['helloLambda.php']); //local debug only
var php = spawn('php-7-bin/bin/php',['imagick.php']);
var output = "";
//send the input event json as string via STDIN to php process
php.stdin.write(JSON.stringify(event));
//close the php stream to unblock php process
php.stdin.end();
//dynamically collect php output
php.stdout.on('data', function(data) {
output+=data;
});
//react to potential errors
php.stderr.on('data', function(data) {
console.log("STDERR: "+data);
});
//finalize when php process is done.
php.on('close', function(code) {
//context.succeed(JSON.parse(output));
callback(null,output);
});
}
But it throws following error 但它引发以下错误
"\nFatal error: Uncaught Error: Class 'Imagick' not found in /var/task/imagick.php:5\nStack trace:\n#0 {main}\n thrown in /var/task/imagick.php on line 5\n"
As stated in the comments above, Imageick is a different than ImageMagick (well is more of a wrapper to access it, I think ). 如上面的评论所述,Imageick与ImageMagick是不同的(我认为它更像是用于访问它的包装器)。 Amazon have a blog that I believe you may have followed.
亚马逊有一个博客 ,我相信您可能会关注。

Which means you're most of the way there. 这意味着您已到达目的地。 From the above blog post, before you go compile php with
./configure --prefix=/home/ec2-user/php-7-bin/
you need to go compile Imagick for your php, so it is bundled with it. 在以上博客文章中,在使用
./configure --prefix=/home/ec2-user/php-7-bin/
编译php之前,需要为您的php编译Imagick,因此将其捆绑在一起。 But you need to compile it statically so its included in final code. 但是您需要静态地对其进行编译,使其包含在最终代码中。 I believe you may also want to compile ImageMagick statically as well so you don't have to rely on the one installed that it will always be installed.
我相信您可能还希望静态地编译ImageMagick,因此您不必依赖将始终安装的ImageMagick。
I don't have the instructions for both of the above anymore, we went down a different route with Magick.NET and wrote our image manipulation tool in C# instead. 我再也没有上述两个说明,我们使用Magick.NET走了一条不同的路线,改为使用C#编写了图像处理工具。 The methods used in php with Imagick and with Magick.NET were easily convertable but it also depends on the rest of your enviroment.
与Imagick和Magick.NET一起在php中使用的方法很容易转换,但这还取决于您的环境。
