我将代码更改为使用 Jquery 表单插件，以便上传图片。我原来的形式很简单
$.ajax({
type: "POST",
url: "register.htm",
data:{
account_name: $('#regAccount_name').val(),
pwd: MD5($('#regPwd').val()),
fname: $('#regFname').val(),
lname: $('#regLname').val(),
},
success: function(data){
changeMainIFrame('MenuFrame.jsp?regStatus=User Successfully Registered');
},
error:function(e){
console.log("sendRegistration(): " + e);
}
});
但改成这个
var options = {
beforeSend: function()
{
//alert(MD5($('#regPwd').val()));
// document.getElementById('regPwd').value = MD5($('#regPwd').val());
},
uploadProgress: function(event, position, total, percentComplete)
{
},
success: function()
{
changeMainIFrame('MenuFrame.jsp?regStatus=User Successfully Registered');
},
complete: function(response)
{
},
error: function(e)
{
console.log("sendRegistration(): " + e);
}
};
$("#regForm").ajaxForm(options);
但是现在我收到一个 400 Bad Request，我认为这意味着我的控制器甚至没有收到请求。这是我的控制器代码：
@RequestMapping("/register.htm")
public String register(// @RequestParam("regProfilePic") File pic,
@RequestParam("regAccount_name") String account_name,
@RequestParam("pwd") String pwd,
@RequestParam("fname") String fname,
@RequestParam("lname") String lname,
ModelMap params){
setup();
System.out.println("Register");
service.registerUser(fname, lname, account_name, pwd);
return "MenuFrame";
}
这是我的 web.xml
