Axios 使用 GET 调用 api 成为 OPTIONS

将我的 javascript 文件放在 apache 服务器上后，Origin 不为空，但我需要将 NelmioCorsBundle 添加到我的 Symfony 项目以允许预检I use axios for calling API (in front-end).I use the method "GET" :import axios from 'axios';import querystring from 'querystring';var url = "mydomain.local", token = "blablabla...blabla";var configs = { headers: { 'Authorization': 'Bearer ' + token, 'Agency': 'demo0' }};var testapi = axios.create({ baseURL: 'http://api.' + url });testapi.get( '/relativeUrl', configs).then(function (response) { console.log(response);}).catch(function (error) { console.log(error);});I got a 405 Method Not Allowed. The method is "OPTIONS" but I use the method ".get()".405 Method Not Allowed. Method OPTIONSI test call api with postman and I get 200 OK :postman 200 OK screenshotAnyone has an idea ? 解决方案 Like @Shilly says, OPTIONS method is pre-flight on modern browsers when Preflighted requests conditions (MDN) :In the response header I had Allow:"GET, HEAD, POST, PUT, DELETE".So OPTIONS method is not available and need to configure it on in the server (Apache).I do the change on apache (/etc/apache2/sites-available/000-default.conf) :Header set Access-Control-Allow-Origin "*"Header set Access-Control-Allow-Headers "*"Header set Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"In Request headers I have :Origin: "null" is a problem. The cause is : file:// URLs produce a null Origin which can't be authorized via echo-back. Don't trying to perform a CORS request from a file:// URL (see this post for more details)After put my javascript file on a apache server, the Origin was not null but I need to add NelmioCorsBundle to my Symfony project to allow preflight 这篇关于Axios 使用 GET 调用 api 成为 OPTIONS的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
