1、如果headers请求头为'Content-Type': 'application/json',则参数body: ({a:1,b:{c:2,d:3}});
2、如果headers请求头为"Content-Type": "application/x-www-form-urlencoded" ,则参数body: "a=1&b=2&c=3",传字符串格式,这里必须用=拼接,冒号拼接会报错!
第二种情况举例如下:
let options = {
headers: {
// 'content-type': 'application/x-www-form-urlencoded;charset=UTF-8'
"Content-Type": "application/json"
}, // 设置请求头
mode:'no-cors',
method:'post',
// body:`user_id=${userID}`, // 参数
body: ({user_id: userID}) // 参数
}
('option', options)
const res = await fetch(url, options)
const data = await ()
const result =
return result
