POST 请求与 Postman 一起使用但获取失败?

With Postman I get the appropriate response but when I try the same thing with fetch, I get a network error

这是我的代码:

fetch ('http://10.1.0.1/cgi-bin/api/write_config', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
        },
        body: JSON.stringify({
          param1: 'attr1',
          param2: 'attr2',
          param3: 'attr3',
        }),
      })
      .then(response => {
        console.log(response.json())
        return response.json()
      })
      .then(data => {

        console.log(data)
      })
      .catch(e => {
        console.log('In catch block')
        console.log(e)
      })

这些是我从响应中获得的标题(在 Postman 中):
