[英]call an external javascript function from python
I have a javascript function that I can call with input and that returns a result. 我有一个javascript函数,我可以使用输入调用,并返回一个结果。 I can integrate this javascript function into an html-document (of course). 我可以将这个javascript函数集成到一个html文档中(当然)。
Now I would like to call exactly this javascript function from python. 现在我想从python中调用这个javascript函数。 I have a python programm and want to call the javascript function with input parameters passed to the JS function by the calling python function. 我有一个python程序,并希望通过调用python函数调用传递给JS函数的输入参数的javascript函数。 And the JS function shall return some result to python. 并且JS函数应该将一些结果返回给python。
This JS function has quite complex functionality and is used in a web project also. 这个JS函数具有相当复杂的功能,也可用于Web项目。 I would like to use same functionality in Python. 我想在Python中使用相同的功能。
Does anyone know how to solve this? 有谁知道如何解决这个问题? Python is quite huge so I think I only did not find the required python module up until know. Python是非常庞大的,所以我认为我只是找不到所需的python模块,直到知道。 I spent 2 days in searching a possibility. 我花了两天时间寻找可能性。
Thanks! 谢谢!
I had similar requirement recently and solved via node. 我最近有类似的要求,并通过节点解决。
module.exports = {decode}; // entry for node
function decode(payload) {
var decoded = {};
// ...
console.log(JSON.stringify(decoded));
return decoded;
}
node -e 'require("./parser.js").decode("foobar")'
output: the parsed data 输出:解析的数据
import subprocess
cmd = """node -e 'require(\"./parser.js\").decode(\"{}\")'"""
output = subprocess.check_output(cmd.format(data), shell=True)
