perl - 为什么我在 IIS 上使用 Perl CGI 程序时会出现 "Bad Gateway"错误？

Question

我试图在 Windows 7 上运行示例 Perl 脚本，并且我配置了 IIS 7 以允许 ActivePerl 运行，但我收到此错误:

HTTP Error 502.2 - Bad Gateway
The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are "Hello World. ".

Module  CgiModule
Notification    ExecuteRequestHandler
Handler Perl Script (PL)
Error Code  0x00000000
Requested URL   http://localhost:80/hello.pl
Physical Path   C:\inetpub\wwwroot\hello.pl
Logon Method    Anonymous
Logon User  Anonymous

and here is my Perl script:

#!/usr/bin/perl
print "Hello World.\n";

Answer 1

从任何 CGI 程序返回的第一个输出应该是标题。

尝试

#!/usr/bin/perl
print "Content-type: text/plain\n\n";
print "Hello World.\n";
