413：请求实体太大（client_max_body_size被设置）

我真的不知道还有什么地方可以find答案。 网上的每一个指南或问题说检查client_max_body_size并解决它。

然而，对于我来说，我正在尝试对我自己的服务器上的PHP文件执行大的PUT请求。

我有… client_max_body_size 32M; 在nginx.conf服务器块中。 我知道这是有效的，因为WordPress的正确的上传大小设置为32MB。

除此之外，我发现我需要检查3个PHPvariables，我不记得它们是什么，但它们都足够远（在几百MB）。

• Apache：只允许某些HTTP请求，拒绝其他所有
• 不能访问我的局域网外，我的外部IP地址，OS X上的Apache服务器
• Nginx，检查请求方法，而不使用IF？
• 在静态内容目录中使用G-WAN Web服务器定制“未find”
• 为max-age = 0请求configurationnginx

也许我需要做一些缓冲区？ 我不知道 ：（

我正在使用的脚本是与第三方服务进行通信的代理脚本。 它logging所有的数据输出，这是目前为止的日志..不知道这是否可以暗示一个问题。

我认为下面是服务器正在发送的内容（因为它在日志文件中，并且正在写入STDOUT，所以我假定php代理脚本正在尝试写入它想要发送的头文件）。

当我使用chrome开发工具时，我没有看到Expect: 100-continue 。 难道这有什么关系吗？

编辑：查看PHP源代码后，它似乎是一个有100个继续的“错误”，这是搞砸了代理脚本…所以忽略下面的所有输出。 我想我会把它放在其他地方，以防万一。

 "PUT /rest/cart HTTP/1.1" "HOST: staging.site.com" "CONNECTION: keep-alive" "CONTENT-LENGTH: 2695" "ACCEPT: application/json, text/javascript, */*; q=0.01" "CACHE-CONTROL: no-cache" "ORIGIN: http://staging.site.com" "X-REQUESTED-WITH: XMLHttpRequest" "USER-AGENT: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.37 Safari/537.36 " "CONTENT-TYPE: application/json; charset=UTF-8 " "REFERER: http://staging.site.com/order/ " "ACCEPT-ENCODING: gzip,deflate,sdch " "ACCEPT-LANGUAGE: en-US,en;q=0.8 " "COOKIE: XXX" "Content-Type: application/json; charset=UTF-8 " "Content-Length: 2695 " "X-UC-Forwarded-For: XXX " "Expect: 100-continue " 

不知道这是否有帮助..但这里是代理脚本。
