我得到这样的错误:

总是一样的。一个url重复使用逗号分隔。不知道是什么引起的。有人知道吗?
更新:另一个错误:
http request count is zero while sending response to client
这是配置。还有其他不相关的东西，但这部分是添加/编辑的

在php-fpm和nginx的docker容器中运行Symfony应用程序时也遇到了同样的问题。
经过一些研究发现，这是由php-fpm的stderr写入nginx日志引起的。例如，php警告(在Symfony调试模式中大量生成)在docker日志php-fpm中重复:

和docker日志nginx:

然后nginx log以
2021/07/09 12:25:46 [error] 30#30: *2 upstream sent too big header while reading response header from upstream ...
我得到了502个错误。
增加nginx配置中的fastcgi_buffer_size是有帮助的，但这似乎更像是抑制问题，而不是治疗。
一个更好的解决方案是禁用php-fpm通过FastCGI发送日志。发现它可以通过设置fastcgi来实现。在PHP .ini中Logging =0(默认为1)。
在将其更改为0后，问题就消失了，nginx日志看起来更干净了。
172.18.0.1 - - [09/Jul/2021:12:36:02 +0300] "GET /my/symfony/app HTTP/1.1" 401 73 "-" "PostmanRuntime/7.26.8"
172.18.0.1 - - [09/Jul/2021:12:36:04 +0300] "GET /my/symfony/app HTTP/1.1" 401 73 "-" "PostmanRuntime/7.26.8"
并且所有的php-fpm日志仍然在它们在php-fpm日志中的位置。
upstream在读取upstream的响应头时发送了太大的头，这是nginx表示“我不喜欢我所看到的”的通用方式。
上游服务器线程崩溃
上游服务器发回无效报头
从STDERR发送回来的通知/警告溢出了它们的缓冲区，它和STDOUT都被关闭
3:查看消息上面的错误日志，它是否与消息前面的日志行一起流?PHP声明:未定义的索引:
示例片段从循环我的日志文件:
2015/11/23 10:30:02 [error] 32451#0: *580927 FastCGI sent in stderr: "PHP message: PHP Notice: Undefined index: Firstname in /srv/www/classes/data_convert.php on line 1090
PHP message: PHP Notice: Undefined index: Lastname in /srv/www/classes/data_convert.php on line 1090
... // 20 lines of same
PHP message: PHP Notice: Undefined index: Firstname in /srv/www/classes/data_convert.php on line 1090
PHP message: PHP Notice: Undefined index: Lastname in /srv/www/classes/data_convert.php on line 1090
PHP message: PHP Notice: Undef
2015/11/23 10:30:02 [error] 32451#0: *580927 FastCGI sent in stderr: "ta_convert.php on line 1090
PHP message: PHP Notice: Undefined index: Firstname
在从底部开始的第3行中，您可以看到缓冲区限制被击中，破坏了，下一个线程在它上面写入。然后Nginx关闭连接并返回502给客户端。
2:记录每个请求发送的所有报头，检查它们并确保它们符合标准(nginx不允许任何超过24小时的内容删除/过期cookie，发送无效的内容长度，因为错误消息在内容计数之前被缓冲了…)Getallheaders函数调用通常可以在抽象的代码情况下帮助解决PHP获取所有头文件的问题
例子包括:
<?php
//expire cookie
setcookie ( 'bookmark', '', strtotime('2012-01-01 00:00:00') );
// nginx will refuse this header response, too far past to accept
....
?>
这:
<?php
header('Content-type: image/jpg');
?>
<?php //a space was injected into the output above this line
header('Content-length: ' . filesize('image.jpg') );
echo file_get_contents('image.jpg');
// error! the response is now 1-byte longer than header!!
?>
1:验证，或做一个脚本日志，以确保您的线程到达正确的终点，并在完成之前不退出。
