带有Golang / Gin后端的POST HTML表单

I am trying to POST a simple HTML form to my backend, which uses Golang and Gin. Here is the HTML:

<form action="/login" method="post" name="loginForm">
          <div>
            <input type="text" placeholder="Email" name="email"></input>
          </div>
          <br /><br />
          <div>
            <input type="password" placeholder="Password" name="password"></input>
          </div>
          <br /><br />
          <input type="submit"></input>
          <br /><br />
        </form>

And here is the route from my main.go:

r.POST("/login", func(c *gin.Context) {
        //What do I need to put here?
        formContent := c.PostForm("loginForm")

        c.JSON(200, gin.H{
            "status":  "posted to login",
            "message": "whoo",
            "form": formContent})
    })

When I submit the form, I receive the JSON response, but formContent is an empty string. I'm guessing I'm using the wrong method on c, but I'm not too experienced with Golang so not sure what to replace it with. I'm also not sure what additional capabilities Gin introduces here, as I'm essentially learning with trial and error from an example project.

How do I properly access the form data on the backend?

    Your form:

    name="email"
    name="password"
    

    Your server-side code:

    formContent := c.PostForm("loginForm")
    

    You are looking for a field which does not exist.

    emailValue := c.PostForm("email");
    passwordValue := c.PostForm("password");
