Calling a Python script from Javascript, both local files
提问by Asgeir
I'm trying to run a python script from a local javascript file (part of a locally running HTML/javascript program).
我正在尝试从本地 javascript 文件（本地运行的 HTML/javascript 程序的一部分）运行 python 脚本。
I've been googling this for hours and found a lot of solutions, none of which actually work for me.
我已经在谷歌上搜索了几个小时并找到了很多解决方案，但没有一个真正适合我。
Here is the javascript:
这是javascript：
$.ajax({
type: "POST",
url: "test.py",
data: { param: " "}
}).done(function( o ) {
alert("OK");
});
The test.py file is in the same folder as the script/html file.
test.py 文件与 script/html 文件位于同一文件夹中。
here is the script:
这是脚本：
#!/usr/bin/python
import os
filepath = os.getcwd()
def MakeFile(file_name):
temp_path = filepath + file_name
with open(file_name, 'w') as f:
f.write('''\
def print_success():
print "sucesss"
''')
print 'Execution completed.'
MakeFile("bla.txt");
It works fine when run normally.
正常运行时它工作正常。
On my Firefox console I get a "not well formed" error and the script doesn't create a file. However, I can see that Firefox does fetch the script, as I can view it in my browser by clicking the file name.
在我的 Firefox 控制台上，我收到一个“格式不正确”的错误，并且脚本没有创建文件。但是，我可以看到 Firefox 确实获取了脚本，因为我可以通过单击文件名在浏览器中查看它。

In order for the python script to execute it has to be deployed by a web server that supports it via CGI or WSGI, etc.
为了让 python 脚本执行它，它必须由通过 CGI 或 WSGI 等支持它的 Web 服务器部署。

There are three problems with your code.
您的代码存在三个问题。
First, when you call $.ajax(), it tries to parse the response as either JSON or HTML. To prevent it, use dataType: "text".
首先，当您调用 时$.ajax()，它会尝试将响应解析为 JSON 或 HTML。为了防止它，请使用dataType: "text".
$.ajax({
type: "POST",
url: "111212.py",
data: { param: " "},
dataType: "text"
}).done(function( o ) {
alert("OK");
});
Second, fetching a local file from javascript may violate the Same Origin Policy, depending on the browser. See: Origin null is not allowed by Access-Control-Allow-Origin
其次，根据浏览器的不同，从 javascript 获取本地文件可能会违反同源策略。请参阅：Access-Control-Allow-Origin 不允许 Origin null
An most important, fetching does not execute a file, it just reads it and returns as a string.
最重要的是，fetching 不执行文件，它只是读取它并作为字符串返回。

So apparently, as has been pointed out, this can't be done, not like this. So I'm going to start a simple CGI python sever to server the HTML file, and execute the script. I've tested it and it works great!
显然，正如已经指出的那样，这是不可能的，不是这样的。所以我将启动一个简单的 CGI python 服务器来处理 HTML 文件，并执行脚本。我已经测试过了，效果很好！
