我試圖使用提取創建獲取請求。請求看起來像這樣:使用僅提取選項創建獲取請求發送
fetch('https://requestb.in/14ikb6j1', {
method: 'get',
headers: {
'Authorization': 'Token token=xxxxx'
}});
如果我向我自己的服務器發出這個請求,它每次都會在選項請求上失敗。我無法弄清楚爲什麼。
如果我向requestbin發出這個請求,首先有一個選項請求。但是,在收到選項響應之後,實際的獲取請求將不會生成。
這是requestbin收到什麼:

我怎樣才能讓這個獲得與認證頭的請求工作?
''Content-Type':'application/json'' for a GET request。是對的嗎? – Forivin
@Forivin對不起,您是對的。更新後,刪除這些內容類型標題不會改變任何內容。 – Randy
