Fetch Error :-S SyntaxError: Unexpected token < in JSON at position 0 REACT

Question

 let url = "/"
    fetch(url, {
      headers: {
        "Accept": "application/json",
        "Content-Type": "application/json"
      }
    })
    .then(resp => resp.json())
    .then(data => {
    setToken(1);
   })
   .catch(function(err) {  
    console.log('Fetch Error :-S', err);  
    });

我有代理OK：http://localhost:3001/people

我配置了这个 json-server

{
  "people": [
    {
      "id": "1",
      "name": "gustavo",
      "pass": "gustavo",
      "days": {
        "23/02/2021": [
          {
            "arrive": "09:00",
            "lunchstart": "12:00",
            "lunchend": "13:00",
            "exit": "17:00"
          }
        ],
        "24/02/2021": [
          {
            "arrive": "09:00",
            "lunchstart": "11:30",
            "lunchend": "13:00",
            "exit": "17:00"
          }
        ]
      }
    }
  ]
}

如果使用“/1”就可以了。如何只使用“/”？

我也可以使用 INSOMNIA OR POSTMAN，它适用于 /people

Answer 1

我刚刚将代理更改为：

 "proxy": "http://localhost:3001"

并提取到：

let url = "people?name=gustavo" or
let url = "people"

我花了2天的时间才解决这个问题，谢谢大神哈哈

有人有其他解决方案吗？
