在Django 1.9中,可以通过AJAX请求来更改密码并保持会话。下面是一个完善且全面的答案:
在Django中,可以使用AJAX请求来更改密码并保持会话。以下是一种实现方式:
下面是一个示例代码:
前端页面(HTML):
<form id="change-password-form">
<input type="password" id="new-password" placeholder="New Password">
<input type="password" id="confirm-password" placeholder="Confirm Password">
<button type="submit">Change Password</button>
</form>
<script>
document.getElementById("change-password-form").addEventListener("submit", function(event) {
event.preventDefault(); // 阻止表单默认提交行为
var newPassword = document.getElementById("new-password").value;
var confirmPassword = document.getElementById("confirm-password").value;
// 发送AJAX请求
var xhr = new XMLHttpRequest();
xhr.open("POST", "/change-password/", true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.onreadystatechange = function() {
if (xhr.readyState === XMLHttpRequest.DONE) {
if (xhr.status === 200) {
var response = JSON.parse(xhr.responseText);
alert(response.message);
} else {
alert("Failed to change password.");
}
}
};
var data = JSON.stringify({
"new_password": newPassword,
"confirm_password": confirmPassword
});
xhr.send(data);
});
</script>
后端视图函数(Python):
from django.contrib.auth import authenticate, login
from django.http import JsonResponse
def change_password(request):
if request.method == "POST":
user = authenticate(request, username=request.user.username, password=request.POST.get("current_password"))
if user is not None:
new_password = request.POST.get("new_password")
confirm_password = request.POST.get("confirm_password")
if new_password == confirm_password:
user.set_password(new_password)
user.save()
login(request, user)
return JsonResponse({"message": "Password changed successfully."})
else:
return JsonResponse({"message": "New password and confirm password do not match."})
else:
return JsonResponse({"message": "Current password is incorrect."})
return JsonResponse({"message": "Invalid request method."})
请注意,以上代码仅为示例,实际应用中可能需要根据具体情况进行适当的修改和优化。
