React Native Fetch Api 无法设置 Cookie 标头
我正在开发一个 react native 应用程序和 php rest 服务作为后端.
I am developing a react native app and php rest service as backend.
当用户登录时，我使用 json_encode() 函数将用户和会话 ID 信息回显为 $response 数组.
When user login i echo user and session id info as $response array with json_encode() function.
$response['user'] 存储用户信息.$response['sessid'] 存储会话 ID.
$response['user'] stores user info.
$response['sessid'] stores session id.
在 Postman 中，我可以将 Header 设置为 Cookie，并使用 sessionid 作为值.它完美地工作.但是在 fetch api 中我无法设置 Cookie 标头.
In Postman i can set a Header as Cookie and as value i use sessionid. It works perfectly. But in fetch api i can't set Cookie header.
这是我的代码:
const value = await AsyncStorage.getItem('sessid');
console.log("value" + value)
var url = 'http://192.168.1.27/zuper/test.php';
fetch(url, {
method: 'GET',
headers:{
'Accept': 'application/json',
'Content-Type': 'application/json',
'Cookie' : value
}
}).then( (response) => {
console.warn(response)
})
这是值变量的值:0d580f8b8e1e1ead1ce038cb12289a57
对这个获取的响应带有一个 php 错误，上面写着
Response for this fetch comes with a php error which says
用户未定义
从行 $_SESSION['user']['name']
推荐答案
你是对的.Cookie 列在禁止的标头名称中:
You are correct. Cookie is listed amoung the forbidden header names:
这些是被禁止的，所以用户代理仍然可以完全控制它们.
These are forbidden so the user agent remains in full control over them.
如果您想在 HTTP 请求中发送 Cookie，则必须先向使用 Set-Cookie 响应标头设置的同一来源发出 HTTP 请求.
If you want to send a Cookie in an HTTP request, then you must make a prior HTTP request to the same origin that uses a Set-Cookie response header to set it.
