通過 Fetch API 驗證登錄

Question

我正在嘗試通過 API 連接到某個服務，第一步是對服務的登錄進行身份驗證，下面是我當前的代碼：

fetch("https://api.connectservice.com/login",
{
    headers: {
      "Accept": "application/json",
      "Content-Type": "application/json"
    },
    method: "POST",
    body: {
  "username": "usermn",
  "password": "m$p@ss"
}
}).then(response => {
  if (!response.ok) throw new Error(response.status);
  return response.json();
})

當我運行上面的代碼時，我收到錯誤：

(index):1 Uncaught (in promise) TypeError: Failed to fetch

我將感謝您的幫助解決問題

這是我的請求之一的示例

const data = {
        email: this.state.email,
        password: this.state.password,
        date
      };
      console.log(date);

      fetch("/login", {
        method: "POST", // or 'PUT'
        headers: {
          Accept: "application/json,",
          "Content-Type": "application/json"
        },
        body: JSON.stringify(data)
      })

嘗試傳遞類似於此的數據
