Question

我正在尝试实现基本用户注册RESTful api。我有一个html表单registerform.html，deregisterform.html，users.php，register.php和deregister.php，它们都粘贴在下面。

当我在浏览器中访问registerform.html时，我可以填写详细信息，users.php脚本会收到一个POST请求，并回显一个json响应，显示刚刚添加的用户的id号。我的问题是，当我使用deregister表单时，users.php脚本应该重新发送DELETE请求，但实际上是在获取GET请求。我一直在寻找这个问题的答案，但我找不到解决方案。

registerform.html

<form action="users.php" method="POST">
    Username: <input type="text" name="uname" /><br />
    FirstName: <input type="text" name="fname" /><br />
    Last Name: <input type="text" name="lname" /><br />
    Date of Birth: <input type="date" name="dob" /><br />
    Telephone: <input type="mob" name="tel" /><br />
    Email: <input type="email" name="email1" /><br />
    Confirm Email: <input type="email" name="email2" /><br />
    Password: <input type="password" name="pass1" /><br />
    Confirm Password: <input type="password" name ="pass2" /><br />
    <input type="submit" value="Register" name="sub" />
    
    <br/><A HREF="login.php">Already Registered? Login Here</A><br/>
</form>

deregisterform.html

<form action="users.php" method="DELETE">
    Username: <input type="text" name="uname" /><br />
    Password: <input type="password" name="pass1" /><br />
    Confirm Password: <input type="password" name ="pass2" /><br />
    <input type="submit" value="Deregister" name="sub" />
</form>

任何想法我做错了什么？

Answer 1

您不能将DELETE用作表单操作。

从specs开始，我们有：

method和formmethod内容属性是枚举属性   使用以下关键字和状态：


关键字get，映射到状态 GET ，表示HTTP GET方法。

关键字post，映射到状态 POST ，表示HTTP POST方法。


这些属性的默认值无效是GET状态。

php服务器方法发送GET而不是DELETE
