有人可以告诉我我在做什么错

Question

我正在尝试使用流明后端进行登录服务。在邮递员中，它可以按预期工作，但是当我尝试使用onSubmit函数发送表单数据时，它会返回200，但返回html而不是api令牌。任何帮助将不胜感激。

这是我在浏览器中得到的响应，所以我知道我不是通过怀特方式传递数据，但我不知道正确的方式是什么

这是我要显示的响应并将api令牌保存在本地存储中

Answer 1

就像@Joel所说的那样，问题在于后端期望用户名和密码作为查询参数。您可以像这样编辑登录服务：

this.http.post( this.env.LOCAL_ENDPOINT + '/login?user=' + user.email + "&password=" + user.password, { responseType: 'text' } );

但是，在URL中以纯文本形式发送密码是非常不明智的做法，因此，我建议您重新考虑，而应更改后端，以便它期望用户名并传入标头。

Answer 2

根据邮递员的屏幕快照，当您将数据作为查询参数发送时，后端可以工作，但您应该将其作为表单数据发送。

login(user){
   let userData = new FormData();
   userData.append('email', user.email);
   userData.append('password', user.password);
   return this.http.post(this.env.LOCAL_ENDPOINT + '/login',userData);
}
