axios

问题 I'm a little new to creating a backend in Node/Express, but I am trying use axios to make HTTP requests. I've set up express routes that will make the necessary request and I know from using Postman that GET request I'm testing does return a response. Where I'm stuck is how to return that data and send it to my React/Redux app to use. -Server Side- //Express Route app.get('/api/recipes', recipeController.getRecipes) //Controller Function that makes axios request const axios = require('axios')

问题 Ok, so i have the following method. Basically I am calling an API backend, posting username and password, and if those pass, in the response, the server sends me a 200 status. What I want to do, is in the response, after I get the status, run an if/else, so if the status is 200, redirect, else display an error message. every time i try to use 'this.$router.push('/any route here')', I get an error: 'homepage.vue?3ec6:72 Uncaught (in promise) TypeError: Cannot read property '$router' of

问题 I've created a page where I want to get all my data from the database with an API call, but I'm kinda new to VueJS and Javascript aswell and I don't know where I'm getting it wrong. I did test it with Postman and I get the correct JSON back. This is what I get: [__ob__: Observer] length: 0 __ob__: Observer {value: Array(0), dep: Dep, vmCount: 0} __proto__: Array This is what I want: (140) [{…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…},

问题 I'm trying to generate a pre-signed URL then upload a file to S3 through a browser. My server-side code looks like this, and it generates the URL: let s3 = new aws.S3({ // for dev purposes accessKeyId: 'MY-ACCESS-KEY-ID', secretAccessKey: 'MY-SECRET-ACCESS-KEY' }); let params = { Bucket: 'reqlist-user-storage', Key: req.body.fileName, Expires: 60, ContentType: req.body.fileType, ACL: 'public-read' }; s3.getSignedUrl('putObject', params, (err, url) => { if (err) return console.log(err); res

问题 I am using Axios JS library for sending post json request. but I am not receiving anything at the server. Here is my code const dt = JSON.stringify({"data":{"value":"gdfg1df2g2121dgfdg"}}); const request = axios.post(url, {dt}); I need to send post raw body in json format . 回答1: By default axios uses Json for posting data so you don't need to stringify your data. The problem could be that you're doing that. Could you try doing the post without it and check if it works? Also you don't need the

问题 So the backend (not under my control) requires a query string like this: http://example.com/?foo=5&foo=2&foo=11 But axios uses JS object to send the request params: axios.get('http://example.com/', { foo: 5 }); And obviously such object can't have multiple fields with the same key. How can I send a request with multiple fields with same key? 回答1: From the axios documentation on the request config // `params` are the URL parameters to be sent with the request // Must be a plain object or a

问题 I have ajax call in componentdidmount. And and then setState inside the ajax promise. The code is like this componentDidMount(){ axios.post('mydomian.com/item/',this.state) .then(function (response) { const res = response.data if (res.status === 'OK') { this.setState({items :res.list}) }else{ console.log('can not load data', response) } }.bind(this)) } componentWillUnmount(){ how to stop everything about axios? } This causes error 'can not setstate on an unmounted component', when I navigate
