sse get请求 怎么自定义header？

发起sse get请求，自定义header时，这样写对吗
sse.initSSEInstance()
sse.sendSSEMsg({ //发送sse请求
method: 'GET',
header: {
'content-type': 'application/json',
'Authorization': 'SID 3b02ea97ad268d33',
'X-Device': 'mini'
},
data: {},
enableChunked: true,
url: baseUrl
}, (onEventRes) => {
console.log('onEventResData', Data);
let Data = JSON.parse(onEventRes)
}, (onOpenRes) => {
console.log('onOpenRes', onOpenRes)
}, (closeRes) => {
console.log('closeRes', closeRes)
}, (onFailureRes) => {
console.log('onFailureRes', onFailureRes)
})
