Vue + Spring：没有通过 CORS 测试

Question

我的 Spring 应用程序在地址 localhost:8081 上运行 我的前端 Vue.js 在地址 localhost:8080 上运行。

我有 WebMvcConfig：

...

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry
            .addMapping("*")
            .allowedOrigins("http://localhost:8080");
    }

}

我在 Vue 组件中有请求

import HTTP from '../api/http-common'
...
 HTTP.post('/registration', this.form)
                    .then(response => {
                        if (response.data.errors) {
                            this.errors = response.data.errors
                        } else {
                            this.$router.push("/");
                        }
                    })

这里是http-common

import axios from 'axios'

export default axios.create({
    baseURL: 'http://localhost:8081/api'
})

它以前可以工作，我在WebMvcConfig 下：

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry
            .addMapping("/api/registration")
            .allowedOrigins("http://localhost:8080");
    }

}

然后我必须向地址 localhost:8081/api/activate/{code} 发出请求。 我在“/api/activate/**”上替换了“/api/registration”，但它不起作用。现在这两个设置都不起作用了。

我想允许来自 localhost:8080（我的前端 Vue.js 正在运行的地方）的所有请求

我在浏览器 Chrome 中进行了下一次 CORS 测试：

来自控制台的错误：

Access to XMLHttpRequest at 'http://localhost:8081/api/registration' from origin 'http://localhost:8080' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

createError.js?2d83:16 Uncaught (in promise) Error: Network Error

    at XMLHttpRequest.handleError (xhr.js?b50d:81)

Answer 1

接下来我需要写，然后就可以了：

.addMapping("/api/**")
