前端如何向后端发送数组/对象，Note:further occurrences of HTTP request parsing errors will be logged at DEBUG level

错误信息

 Note: further occurrences of HTTP request parsing errors will be logged at DEBUG level.

java.lang.IllegalArgumentException: Invalid character found in the request target [/admin-api/yyang/equipment-data/test-array?str=[%271%27,%272%27,%273%27] ]. The valid characters are defined in RFC 7230 and RFC 3986

 后端代码

 @GetMapping("/test-array")
    public void testArray(String[] str) {
        System.out.println("str = " + Arrays.toString(str));
    }

我是如何解决的呢

1.使用postman测试工具对url发起请求，获得错误信息 

2.将前端请求方式，以及后端代码全部发送给AI，让他帮忙解析

我当时的请求如下

前端
postman : get请求方式 http://localhost:48080/admin-api/yyang/equipment-data/test-array?str=['1','2','3']

后端
@GetMapping("/test-array")
    public void testArray(String[] str) {
        System.out.println("str = " + Arrays.toString(str));
    }

AI给的解决方案

按照方法测试

结果

List接收方式

注意@RequestParam（"str"）的意思，只要是对象接收就得加

前端依旧可以这样请求
