在Apache上执行Julia;设置APPDATA和家庭环境变量

我想在Apache上执行浏览器中的Julia代码（我在Windows 10上使用Ampps）。我能够执行它真正的命令提示符或通过python代码调用它（请参阅下面的python代码）。当我尝试直接在浏览器上执行Julia代码时，我得到网关超时服务器没有及时响应消息。但是，当我尝试执行调用朱莉娅代码的Python代码，我在Apache的错误日志获得更详细的信息：在Apache上执行Julia;设置APPDATA和家庭环境变量

这似乎是与APPDATA环境变量是如何在Julia集的已知问题。 Here，建议HOMEDRIVE，HOMEPATH和APPDATA的env变量应在httpd.conf或httpd-vhosts.conf中设置。我试过编辑httpd-vhosts.conf和httpd.conf，但我仍然得到相同的错误。

这是我编辑了httpd.conf：

#### Localhost VirtualHost #### 

<VirtualHost 127.0.0.1:80> 
<Directory "{$path}/www"> 
    Options Indexes FollowSymLinks ExecCGI 
    AddHandler cgi-script .cgi .py .jl 
    AllowOverride All 
    Order deny,allow 
    allow from All 
</Directory> 
SetEnv HOMEDRIVE "C:" 
SetEnv HOMEPATH "/Users/Reza" 
SetEnv APPDATA "C:/Users/Reza/AppData/Roaming" 
ScriptLog logs/julia_cgi.log 
ServerName localhost 
ServerAlias localhost 127.0.0.1 
ScriptAlias /cgi-bin/ "{$path}/www/cgi-bin/" 
DocumentRoot "{$path}/www" 
ErrorLog "{$path}/apache/logs/error.log" 
CustomLog "{$path}/apache/logs/access.log" combined 
</VirtualHost>

这是调用朱莉娅代码的Python代码：

#!"C:/Python27/ArcGIS10.3/python.exe" 

import subprocess 

print "Content-Type: text/html\n\n" 
print "hi there! this is python!" 

command="C:/Users/Reza/AppData/Local/Julia-0.5.1/bin/julia.exe" 
path2script="C:/Program Files (x86)/Ampps/www/csvToLayer_JSAPI/HT.jl" 
cmd = [command, path2script] 

x = subprocess.check_output(cmd) 

print x

这是朱莉娅代码：

#!"C:/Users/Reza/AppData/Local/Julia-0.5.1/bin/julia.exe" 
redirect_stderr(STDOUT) 
println("Content-Type: text/html\n\n") 
println("hi there; this is Julia!"); 
println("Julia is passing outputs to Python");

我可以为APPDATA env变量设置一个位置吗？我应该使用什么文件夹作为APPDATA？除了“C：/ Users/Reza/AppDate/Roaming”之外，我还尝试了“C：/ Users/Reza/AppDate/Local”和“C：/Users/Reza/AppDate/Local/Julia-0.5.1” ，并且我得到相同的错误。

我不知道为什么SetEnv在httpd.conf中不起作用，但我找到了解决方法。我在Python中设置环境变量：

#!"C:/Python27/ArcGIS10.3/python.exe" 
import subprocess,os 

print "Content-Type: text/html\n\n" 
print "hi there! this is python!" 

os.environ["HOMEDRIVE"]="C:" 
os.environ["HOMEPATH"]="/Users/Reza" 
os.environ["APPDATA"]="C:/Users/Reza/AppData/Roaming" 

command="C:/Users/Reza/AppData/Local/Julia-0.5.1/bin/julia.exe" 
path2script="C:/Program Files (x86)/Ampps/www/csvToLayer_JSAPI/HT.jl" 
cmd = [command, path2script] 

try: 
    print subprocess.check_output(cmd) 
except subprocess.CalledProcessError as e: 
    print e.output
