sae的curl限制能否突破?
我先说下我的情况:
curl到国外的web service上面,发送数据,处理后,再返回数据。

之前使用了美国空间,香港空间,但是总不满意,无法满足国内各地区的快速访问。

所以我现在放到了sae上面运行,但是sae有很多限制的,比如curl的限制如下:
connect_timeout 5秒 
send_timeout 15秒 
read_timeout 20秒 
抓取文件大小 8MB 
禁用头,这些头用户无法修改 Content-Length、Host、Vary、Via、X-Forwarded-For、FetchUrl、AccessKey、TimeStamp、Signature、AllowTruncated、ConnectTimeout、SendTimeout、ReadTimeout 


目前就是第一条把我给限制住了,后面的限制对我没有影响。

正是由于他的connect_timeout 5秒 限制,导致我的curl应用经常返回502/504错误提示。

这个出错比例大概在3%左右,也就是运行100次,就会出错3次,后来我将curl里的网址由https换成http,这样出错概率降低了不少,但还是存在,测试在1%左右。

对于结果我还是不满意。因为我的curl程序在其他地方(国内三家机房测试)运行都没有出现过错误。

当然我也给sae提出建议,甚至要求升级成付费用户,都没有回复。

惟一的一个管理员说跟我要了curl的网址说帮我找台机器测试看看是不是有这回事。

可能有人说你为什么要在sae这棵树上吊死?

说实话我看中sae的惟一优势是他们是5线机房,国内大部分地区的用户访问速度非常不错的。再说我申请通过开发者认证,每个月的云豆应该足够使用了。

现在似乎有三种选择:
1.继续给sae建议,让他们修改限制参数
2.优化代码?我实在想不出如何优化了
3.放弃sae,这不是我最终想要的结果



我的curl代码是这样的:

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->    #POST方法        $curl = curl_init($url);        curl_setopt( $curl, CURLOPT_POST, 1 );        curl_setopt( $curl, CURLOPT_POSTFIELDS, $data );        curl_setopt( $curl, CURLOPT_HEADER, 0 );        curl_setopt( $curl, CURLOPT_RETURNTRANSFER , 1 );        $response = curl_exec($curl);        #GET方法        $curl = curl_init($url);        curl_setopt( $curl, CURLOPT_GET, 1 );        curl_setopt( $curl, CURLOPT_GETFIELDS);        curl_setopt( $curl, CURLOPT_HEADER, 0 );         curl_setopt( $curl, CURLOPT_RETURNTRANSFER , 1 );        $response = curl_exec($curl);
Copy after login


------解决方案--------------------
对于限制多多的机房我个人是扭头就走的.国内你一般只需要考虑电信网通(现在叫联通?)双线就行了,其他商用接入都是最后接到他们的网上。如果是用空间我还真没啥建议,我没用过任何一款空间,有经济基础的话似乎可以考虑美国的主机,或者香港的主机。

放弃sae 转战阿里云 然后回头来汇报一下情况好给我参考...哈哈哈
云豆够用吗?我不太相信...

至于curl的优化...这还能优化么...
------解决方案--------------------
你应该给出一些测试用的 url

How to configure Nginx timeout timeout How to configure Nginx timeout timeout May 12, 2023 pm 10:07 PM

keepalive_timeouthttp has a keepalive mode, which tells the webserver to keep the TCP connection open after processing a request. If it receives other requests from the client, the server will use this unclosed connection without establishing another connection. httpkeep-alive, every request on the web page is http (pictures, css, etc.), and to open an http request, you must first establish a tcp connection. If a page needs to open and close a tcp connection for each request, it will become a resource. The waste of keepalive_timeout is that when an http request is completed, its tcp connection will remain
