[英]Setting Content-Type in fetch request not working
I am doing a remote fetch request to a server. 我正在对服务器执行远程获取请求。 The payload is in JSON format, so I want to change the
Content-Type
header to application/json
. 有效负载为JSON格式,因此我想将
Content-Type
标头更改为application/json
。 I have used the following code to do this: 我已使用以下代码执行此操作:
let email = document.getElementById("email").value
let password = document.getElementById("password").value
const body = {"email":email, "password":password}
const headers = new Headers({
"Content-Type": "application/json",
"Content-Length": JSON.stringify(body).length
})
const options = {
method: "POST",
mode: "no-cors",
headers: headers,
body: JSON.stringify(body)
}
console.log(options)
const response = await fetch('http://xx.xx.xx.xxx/login', options)
const json = await response.json()
console.log(json)
However, in the Chrome developer tools console, the Content-Type
header of the request is still text/plain;charset=UTF-8
. 但是,在Chrome开发人员工具控制台中,请求的
Content-Type
标头仍为text/plain;charset=UTF-8
。 What am I doing wrong? 我究竟做错了什么?
Overriding the Content-Type request header is not allowed for no-cors
requests. no-cors
请求不允许覆盖Content-Type请求标头。
Change the mode to cors
. 将模式更改为
cors
。
