为防止跨侧脚本,我将CSP应用于我的某个应用程序。目前我正在重新配置所有的html类,因此javascript总是来自我的服务器。
现在我找到了一个包含Ajax.BeginForm
的网页,如果我想提交表单并更新视图,则始终会收到错误“Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self'".
”。
任何人都可以帮助我,问题出在哪里?
这是我的html类(简称):
UserInformation.cshtml:
<div id="OpenAccountInformation">@Html.Action("OpenAccountInformation")</div>
</div>
AccountInformation.cshtml:
@Scripts.Render("~/Scripts/bundles/ManageUsers/AccountInformation")
@model Tumormodelle.Models.ViewModels.AzaraUserModel
<input type="hidden" value="@ViewBag.Editable" id="EditableUserInformation">
<div id="Editable">
@using (Ajax.BeginForm("EditUser", "ManageUsers", new AjaxOptions { InsertionMode = InsertionMode.Replace, UpdateTargetId = "OpenAccountInformation", HttpMethod = "post", }))
{
@Html.AntiForgeryToken()
@Html.HiddenFor(m => m.UserID)
<div>
<div>
@Html.LabelFor(m => m.Username, new { @class = "entryFieldLabel" })
</div>
</div>
<div>
<div>
<button name="button" value="save" class="formbutton" id="saveButton">save</button>
<button name="button" value="cancel" class="formbutton" id="cancelButton">cancel</button>
</div>
}
</div>
<div id="NonEditable">
<div>
<div>
@Html.LabelFor(m => m.Username, new { @class = "entryFieldLabel" })
</div>
</div>
<div>
<div>
<button name="button" value="edit" class="formbutton" id="editButton" type="button">edit</button>
</div>
</div>
</div>
和c#方法:
public ActionResult EditUser(AzaraUserModel AzaraUserModel, string button)
{
if (button == Tumormodelle.Properties.Resources.Save)
{
if (ModelState.IsValid)
{
azaraUserManagement.Update(AzaraUserModel.Username, AzaraUserModel.Title, AzaraUserModel.FirstName, AzaraUserModel.LastName, AzaraUserModel.EMailAddress, null, AzaraUserModel.Phone, AzaraUserModel.UserID, (byte)AzaraUserModel.ShowMail.ID);
ViewBag.Message = Tumormodelle.Properties.Resources.Personal_Data_Changed;
ViewBag.Editable = true;
}
else ViewBag.Editable = false;
BindShowMailList();
return PartialView("AccountInformation", AzaraUserModel);
}
else
{
return RedirectToAction("OpenAccountInformation", "ManageUsers");
}
}
public ActionResult UserInformation()
{
return View("UserInformation");
}
public PartialViewResult OpenAccountInformation()
{
AzaraUserModel AzaraUserModel = new AzaraUserModel(azaraUserManagement.GetSingle(AzaraSession.Current.UserComparison.GetUser().Id));
BindShowMailList();
ViewBag.Editable = true;
return PartialView("AccountInformation", AzaraUserModel);
}
编辑:在Chrome调试器的帮助下,我发现错误是在片刻形式被提交时抛出的。

Ajax.BeginForm
将在您生成的页面HTML中生成内联脚本,您在内容安全策略中使用script-src 'self'
禁止使用该脚本。
如果要使用CSP来阻止任何内联注入脚本,则必须使用Html.BeginForm
并添加JavaScript以通过外部.js
文件中的Ajax提交。
