但我可以通过使用axios call或express server来实现这一点
如果我可以使用vue axios或express server执行此操作,是否有人可以帮助我使用正确的语法 听起来您想在Vue首页的服务器中使用
express
和axios
,而不是服务器端的节点http
服务器和https
客户端
用express
替换节点http
非常简单,如下所示
const express = require('express')
const path = require('path');
const app = express()
const port = 8050
app.use(express.static(path.join(__dirname, '.')))
app.get('/', (req, res) => res.sendFile('index.html'))
app.use(function (req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err)
})
app.use(function (err, req, res, next) {
if(err.status == 404) {
res.status(404).send("Error 404: Page not Found!")
}
res.status(500).send("Error 500: Internal Error!")
})
app.listen(port, () => console.log("Server is now running on port 8050"))
const axios = require('axios');
var host = 'ussouthcentral.services.azureml.net'
var path = '/workspaces/fda91d2e52b74ee2ae68b1aac4dba8b9/services/1b2f5e6f99574756a8fde751def19a0a/execute?api-version=2.0&details=true'
var api_key = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=='
const pred = axios.create({
baseURL: 'https://'+host,
timeout: 1000,
headers: {'Content-Type':'application/json', 'Authorization':'Bearer ' + api_key}
});
app.post('/mls-api', (req, res) => pred.post(path, JSON.stringify(req.body)).then(function(resp) {
resp.pipe(res)
}))
但考虑到调用Azure机器学习Studio API的代码> API密钥< /COD>值的安全性,我建议不要在VUE首页中用“代码> AXIOS”调用API,仍然通过“代码> Express < /C>”在服务器端进行调用。
const express = require('express')
const path = require('path');
const app = express()
const port = 8050
app.use(express.static(path.join(__dirname, '.')))
app.get('/', (req, res) => res.sendFile('index.html'))
app.use(function (req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err)
})
app.use(function (err, req, res, next) {
if(err.status == 404) {
res.status(404).send("Error 404: Page not Found!")
}
res.status(500).send("Error 500: Internal Error!")
})
app.listen(port, () => console.log("Server is now running on port 8050"))
const axios = require('axios');
var host = 'ussouthcentral.services.azureml.net'
var path = '/workspaces/fda91d2e52b74ee2ae68b1aac4dba8b9/services/1b2f5e6f99574756a8fde751def19a0a/execute?api-version=2.0&details=true'
var api_key = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=='
const pred = axios.create({
baseURL: 'https://'+host,
timeout: 1000,
headers: {'Content-Type':'application/json', 'Authorization':'Bearer ' + api_key}
});
app.post('/mls-api', (req, res) => pred.post(path, JSON.stringify(req.body)).then(function(resp) {
resp.pipe(res)
}))
然后,您可以使用下面的数据值从Vue首页调用/mls api
url
var data = {
"Inputs": {
"input1": {
"ColumnNames": ["gl10", "roc20", "uo", "ppo", "ppos", "macd", "macds", "sstok", "sstod", "pmo", "pmos", "wmpr"],
"Values": [ [ "0", "-1.3351", "50.2268", "-0.2693", "-0.2831", "-5.5310", "-5.8120", "61.9220", "45.3998", "-0.0653", "-0.0659", "-30.3005" ], ]
},
},
"GlobalParameters": {}
}
axios.post('/mls-api', data)
.then(function (response) {
console.log(response);
})
