Populate table in Vue template component from rest api

我的未来我决定 提交于 2019-12-30 06:39:31
问题 I have a Vue component where I am trying to get rest api (using axios) data to populate a table. The rest call returns a valid json string in chrome. However, I can't get it to populate the table in the template. When I run the view, I get the following error in the rest call: TypeError: Cannot set property 'courses' of undefined Here is the json being returned: [{"CourseId":"architecture","AuthorId":"cory-house","Title":"Architecting Applications","CourseLength":"4:20","Category":"Software

问题 I'm running a Flask-Restful API locally and sending a POST request containing JSON from a different port. I'm getting the error No 'Access-Control-Allow-Origin' header is present on the requested resource. However, when I run curl --include -X OPTIONS http://localhost:5000/api/comments/3 --header Access-Control-Request-Method:POST --header Access-Control-Request-Headers:Content-Type --header Origin:http://localhost:8080 I get HTTP/1.0 200 OK Content-Type: text/html; charset=utf-8 Allow: HEAD,

Waiting for all promises called in a loop to finish

问题 I'm using the axios promise library, but my question applies more generally I think. Right now I'm looping over some data and making a single REST call per iteration. As each call completes I need to add the return value to an object. At a high level, it looks like this: var mainObject = {}; myArrayOfData.forEach(function(singleElement){ myUrl = singleElement.webAddress; axios.get(myUrl) .then(function(response) { mainObject[response.identifier] = response.value; }); }); console.log

问题 I'm building a really easy api and react-native application. The server works well (tested with PostMan) but the application doesn't call the server. It blocks when axios has to send the post request (see below). I'm desperate :-( Loosing too mush time in it. Please, if you can help me... Here is my code LogIn page. It dispatch the action creator (working with redux) giving email and password: ... const LogIn = React.createClass({ submitLogin() { // log in the server if (this.props.email !==

Axios and VueJS, function(response) is not setting a list

问题 I have an request to get some data and add it to a variable, When I use: .then(function(response) { this.persons = response.data; }); It does not assign response.data to this.persons but when I do the following: .then(response => this.persons = response.data); It assigns it fine to use. Please see the js fiddle: https://jsfiddle.net/trhhtyxr/2/ 回答1: As I have explained it here, arrow syntax does not bind it's own this, arguments, super, or new.target. Arrow functions are always anonymous.

Vue.js - validation fails for file upload in axios when multipart/form-data used in header

眉间皱痕 提交于 2019-12-27 17:59:26
问题 I am building a Laravel+Vue.js SPA (Single Page Application) with BootstrapVue, VeeValidate and axios as the HTTP client. Inside axios, when I use multipart/form-data; boundary=${uploadForm._boundary} as the Content-Type in headers then all the validations in Laravel Controller method fail . But if I use 'content-type': 'multipart/form-data' in header then validation works except the file input field. The file field becomes empty in Laravel controller method. This happens within the component
