javascript - 获取请求导致双重获取请求？

问题描述

我想使用 Fetch 做一个获取请求，然后重定向到应用程序页面，问题是重定向它自己封装另一个标头以任何方式进行干净的重定向，使用第一个请求而不是发出另一个请求？谢谢。

// First Request with authorization:
{
  host: 'localhost:3000',
  connection: 'keep-alive',
  'sec-ch-ua': '" Not A;Brand";v="99", "Chromium";v="90", "Google Chrome";v="90"',
  authorization: 'Bearer undefined',
  'sec-ch-ua-mobile': '?0',
  'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36',
  'content-type': 'application/json',

} 

// Second Request no authorization  
{
  host: 'localhost:3000',
  connection: 'keep-alive',
  'sec-ch-ua': '" Not A;Brand";v="99", "Chromium";v="90", "Google Chrome";v="90"',
  'sec-ch-ua-mobile': '?0',
  'upgrade-insecure-requests': '1',
  'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36',

}


// Fetch Request 
fetch('/app', {
      credentials: "same-origin",
      mode: "same-origin",
      method: 'GET',
      //redirect: 'follow',
      headers: {
        "Authorization": `Bearer ${JWTs}`,
        "Content-Type": "application/json"
      }
    })
      .then(response => 
    // this is casing the redirection to happen and and to cause the other Get req making me losse the     Auth header any other way to redirect ?  
        window.location = response.url
      )
      .catch((error) => {
        console.error(error);
      }).catch(err => {
        if (err === "server") return
        console.log(err)
      })

  }
})
