nginx上使用fcgiwrap上游的Python在从上游读取响应头时过早关闭FastCGI stdout

Question

我正在尝试在我的nginxweb服务器上运行helloworld python脚本。当我尝试加载URI时，我遇到了“502 Bad Gateway”错误：http://sub.dom.com/py-bin/hello.py

尝试将响应代码（“HTTP/1.0 200 OK”）添加到hello.py的输出顶部，如下所示：

#!/usr/bin/python

print "HTTP/1.0 200 OK"
print "Content-type: text/html\n\n"
print ""
print "Hello world"
