通过 Fetch API 验证登录

Question

我正在尝试通过 API 连接到某个服务，第一步是对服务的登录进行身份验证，下面是我当前的代码：

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();
})

当我运行上面的代码时，我收到错误：

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

我将感谢您的帮助解决问题

这是我的请求之一的示例

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)
      })

尝试传递类似于此的数据
