我在 Node js 中有 2 个文件。我想合并这 2 个文件,但我遇到了问题。这个文件从 python 文件调用函数
const app = express()
let runPy = new Promise(function(success, nosuccess) {
const { spawn } = require('child_process');
const pyprog = spawn('python', ['./ml.py']);
pyprog.stdout.on('data', function(data) {
success(data);
});
pyprog.stderr.on('data', (data) => {
nosuccess(data);
});
});
app.get('/', (req, res) => {
res.write('welcome\n');
runPy.then(function(testMLFunction) {
console.log(testMLFunction.toString());
res.end(testMLFunction);
});
})
app.listen(4000, () => console.log('Application listening on port 4000!'))
蟒蛇文件ml.py
def testMLFunction():
return "hello from Python"
打印(testMLFunction())
以下文件适用于使用 post 方法单击按钮
var fs = require('fs');
var server = http.createServer(function (req, res) {
if (req.method === "GET") {
res.writeHead(200, { "Content-Type": "text/html" });
fs.createReadStream("./form.html", "UTF-8").pipe(res);
} else if (req.method === "POST") {
var result = "";
req.on("data", function (chunk) {
console.log(chunk.toString());
result = chunk;
//body=body.toUpperCase;
});
req.on("end", function(){
res.writeHead(200, { "Content-Type": "text/html" });
res.end(result);
});
}
}).listen(3000);
我怎样才能做到这一点..
