我真的不知道还能在哪里找到答案。网上的每一个指南或问题都说要检查client_max_body_size，这样就可以解决问题。
PUT然而对我来说，我正在尝试对我自己的服务器上的 PHP 文件发出大量请求。
我已经client_max_body_size 32M;在 nginx.conf 服务器块中设置了...我知道它有效，因为 wordpress 正确地将上传大小设置为 32MB。
除此之外，我发现我可能需要检查 3 个 PHP 变量，我不记得它们到底是什么，但它们都足够大（数百 MB）。
也许我需要对缓冲区做些什么？我不知道 :(
我使用的脚本是用于与第三方服务通信的代理脚本。它将所有数据记录到输出中，这是迄今为止的日志。不确定这是否暗示存在问题。
我认为下面是服务器试发送（因为它在日志文件中并且正在写入 STDOUT，所以我假设 php 代理脚本正在尝试写入它想要发送的标头的日志文件）。
但是当我使用 chrome dev tools 时，我看不到Expect: 100-continue。这和它有什么关系吗？
编辑：查看 PHP 源代码后，似乎 100-continue 是一个“错误”，它搞乱了代理脚本……因此请忽略下面的所有输出。我想我还是会把它放上去，以防它有其他有用的部分。
"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 "

"COOKIE: XXX"
"Content-Type: application/json; charset=UTF-8 "
"Content-Length: 2695 "
"X-UC-Forwarded-For: XXX "
"Expect: 100-continue "
不确定这是否有帮助...但这是代理脚本。

答案1
您能附加相关的 nginx-conf 吗？
您是否知道请求是否已到达 php 位置或是否已在 nginx 停止？
所以你可以通过 POST 上传，但不能通过 PUT 上传？我会开始调查这个问题；当你将 PUT 改为 POST 时会发生什么？
当谷歌搜索时，PUT 413: Request Entity Too Large nginx最受引用的建议就是您已经做过的事情，并且我不会开始弄乱 client_*_temp - vars 和 temp_caching (atm)。
