[英]using node.js with a remote GraphicsMagick server
I have node.js installed on one server. 我在一台服务器上安装了node.js。 I have graphicsmagick https://github.com/aheckmann/gm installed on another server.
我在另一台服务器上安装了graphicsmagick https://github.com/aheckmann/gm 。 The graphics files themselves are also stored on the graphicsmagick server.
图形文件本身也存储在graphicsmagick服务器上。 I want to install & setup the node gm module so that the work/processing is done on the graphicsmagick server.
我想安装和设置节点gm模块,以便在graphicsmagick服务器上完成工作/处理。 However, after reading through the documentation, I don't see how to do this.
但是,在阅读了文档之后,我看不到该如何做。 Of course, I can install graphicsmagic on the same server as node, and have it work properly.
当然,我可以将graphicsmagic与节点安装在同一服务器上,并使它正常运行。 But I don't want to have the heavy image processing happening on the same server as node.
但是我不想在与节点相同的服务器上进行繁重的图像处理。 Is this possible to separate the two?
是否可以将两者分开?
the gm
module is not a server, you need to write a service to manipulate the images with gm
. gm
模块不是服务器,您需要编写服务来使用gm
操作图像。
Something like this using express.js: 使用express.js这样的东西:
var express = require('express');
var app = express.createServer();
app.get('/:image', function (req, res, next) {
// set headers here
gm('/path/to/my/' + req.params.image)
.resize('200', '200')
.stream(function (err, stdout, stderr) {
if (err) next(err);
stdout.pipe(res);
});
});
app.listen(8000);
