摘要: openresty 整合阿里云oss

目前阿里云官方并为提供lua版的sdk，在网上找了几个，感觉不是很理想，于是自己造了一个轮子，目前还是一个单车的轮子，只实现了部分功能，不过也能用了

废话不多说上代码

local oss = require "resty.oss"

local oss_config = {
   accessKey	  =   "your accessKey";
secretKey	  =   "your secretKey";
bucket      =   "your bucket",
   endpoint    =   "your oss endpoint" -- 例如：oss-cn-qingdao.aliyuncs.com
}

local client = oss.new(oss_config)
local url = client:put_object("123", "text/html", "123.json")
ngx.say(url)
client:delete_object('123.json')

client:put_bucket('test-bucket123')
client:put_bucket_acl('test-bucket123', 'private')
client:put_bucket_acl('test-bucket123', 'public-read')
client:delete_bucket('test-bucket123')

上面的例子是直接上传文件并指定内容，文件类型，文件名

真实场景，可能是客户端上传一个文件，然后在nginx获取到文件的内容，文件类型，然后自动生成一个文件名，再调用上面的put_object方法进行上传

文件上传模块可以用lua-resty-upload来处理

lua代码参考:

local upload = require "resty.upload"
local oss = require "resty.oss"

-- 获取上传的文件
function readFile()
local chunk_size = 4096
local form, err = upload:new(chunk_size)
form:set_timeout(20000)
local file = {}
if not err then
while true do
local typ, res, err2 = form:read()
if not typ then
err = err2
print("failed to read: ", err2)
break
end
if typ == 'header' and res[1] == 'Content-Disposition' then
local filename = string.match(res[2], 'filename="(.*)"')
file.name = filename
end
if typ == 'header' and res[1] == 'Content-Type' then
file['type'] = res[2]
end
if typ == 'body' and file then
file[typ] = (file[typ] or '') .. res
end
if typ == "eof" then
break
end
end
end
return file, err
end

local file, err = readFile()

local oss_config = {
   accessKey	  =   "your accessKey";
secretKey	  =   "your secretKey";
bucket      =   "your bucket",
   endpoint    =   "your oss endpoint" -- 例如：oss-cn-qingdao.aliyuncs.com
}

local client = oss.new(oss_config)
local url = client:put_object(file.body, file.type, file.name)
ngx.say(url)

前端代码参考

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Upload</title>
</head>
<body>
<input id="fileupload" type="file"/>
<script type="text/javascript" src="https://cdn.staticfile.org/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript" src="http://blueimp.github.io/jQuery-File-Upload/js/vendor/jquery.ui.widget.js"></script>
<script type="text/javascript" src="http://blueimp.github.io/jQuery-File-Upload/js/jquery.fileupload.js"></script>
<script type="text/javascript">

var url = '/hello';
$('#fileupload').fileupload({
url: url,
dataType: 'text',
done: function (e, data) {
console.log('succcess', data);
},
progressall: function (e, data) {
console.log(data);
}
})
</script>
</body>
</html>
