通过添加以下内容修复了与“SSL握手中的对等方关闭连接”相关的错误：

proxy_ssl_session_reuse of;

但在日志中还是可以看到的。
现在我更感兴趣的是如何修复错误

[error] 3294740#3294740: *2796 lua entry thread aborted: runtime error: rewrite_by_lua(nginx.conf:194):6: attempt to concatenate local 'v' (a table value)
stack traceback:

在Jmeter中，此错误如下所示：

<html>
<head><title>500 Internal Server Error</title></head>
<body>
<center><h1>500 Internal Server Error</h1></center>
<hr><center>nginx/1.18.0 (Ubuntu)</center>

但是在Jmeter中，它强烈地描述了是什么原因导致的，因此，我附加了nginx日志

如果您能帮助我修复这些错误，我将非常高兴。

尝试连接局部'v'（表值）
这是很明显的，您正在尝试连接一个表值。
只有当表有一个实现__concat的元表时，才能对表值进行concat，但显然情况并非如此。
现在我更感兴趣的是如何修复错误
别把table的价值说得太清楚。
参考Lua Ngx API的手册，你会发现ngx.req.get_headers()返回的是一个由表组成的表，而不是一个由字符串或数字组成的表。
对ngx.req.get_headers()返回的表中的每个表运行一个循环，然后执行concat操作。
