Question

在我最新的NetCore（2.0）项目中，我使用的是Rotativa.AspNetCore，自从将其发布到SmarterAsp以来，一切工作正常（本地）。

主要问题是，当我尝试通过api生成PDF文件时，该操作无效，并返回错误：

找不到请求的页面。 [404]

XML解析错误：找不到根元素

位置：https://.../api/file/MembershipRegistrationApplication

第1行，第1列：

这是我的代码

[HttpPost]
[AllowAnonymous]
[Route("/api/file/MembershipRegistrationApplication")]
public async Task<byte[]> MembershipRegistrationApplication([FromBody] RegisterViewModel model)
{
    var education = new List<Education>();

    education.Add(_educationService.IncludeEducation(model.Education));

    var user = new ApplicationUser
    {
        Email = model.Email,
        PhoneNumber = model.PhoneNumber,
        BirthDate = model.BirthDate,
        Address = model.Address,
        PlaceOfBirth = model.PlaceOfBirth,
        MunicipalityOfBirthId = model.MunicipalityId,
        IsMale = model.IsMale,
        FathersName = model.FathersName,
        LastName = model.LastName,
        MaritalStatusId = model.MaritalStatusId,
        CitizenshipId = model.CitizenshipId,
        MunicipalityId = model.MunicipalityId,
        FirstName = model.FirstName,
        NationalityId = model.NationalityId,
        PersonalNumber = model.PersonalNumber,
        ForeignMunicipalityOfBirth = model.ForeignMunicipalityOfBirth,
        Educations = education,
        MaidenName = model.MaidenName
    };

    user = _accountService.IncludeApplicationUser(user);
    return await _pdfGenerator.GenerateMembershipApplication(user);
}

GenerateMembershipApplication方法代码

public async Task<byte[]> GenerateMembershipApplication(ApplicationUser user)
{
    var httpContext = new DefaultHttpContext { RequestServices = _serviceProvider };
    var actionContext = new ActionContext(httpContext, new RouteData(), new ActionDescriptor());

    var bytePDF = new Rotativa.AspNetCore.ViewAsPdf("File/MembershipApplication", user)
    {
        PageMargins = { Top = 10, Right = 1, Bottom = 1, Left = 20 },
        FileName = string.Concat("MembershipApplication", ".pdf")
    }.BuildFile(actionContext);

   return await bytePDF;
}

和ajax调用

$.ajax({
    url: "/api/file/MembershipRegistrationApplication",
    type: 'post',
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    data: JSON.stringify(model),
    success: function (data) {
        var pdfAsDataUri = "data:application/pdf;base64,"+data;
        window.open(pdfAsDataUri);
    },
    error: function (jqXHR, exception) {
        var msg = '';
        if (jqXHR.status === 0) {
            msg = 'Not connect.\n Verify Network.';
        } else if (jqXHR.status == 404) {
            msg = 'Requested page not found. [404]';
        } else if (jqXHR.status == 500) {
            msg = 'Internal Server Error [500].';
        } else if (exception === 'parsererror') {
            msg = 'Requested JSON parse failed.';
        } else if (exception === 'timeout') {
            msg = 'Time out error.';
        } else if (exception === 'abort') {
            msg = 'Ajax request aborted.';
        } else {
            msg = 'Uncaught Error.\n' + jqXHR.responseText;
        }
        console.log(msg);
    }
});

首先，我认为问题出在ajax调用发布的数据上（我也尝试过使用formData，但仍然是相同的错误），并且在尝试了数小时之后，我才发现发生错误的原因是Rotativa。我认为Rotativa引起此问题的另一个原因是，与pdf生成过程无关的其他API可以完美地工作。

我的Rotativa文件夹也有必要的文件，

help-wkhtmltoimage.txt
help-wkhtmltopdf.txt
msvcp120.dll
msvcp140.dll
msvcr120.dll
vcruntime140.dll
wkhtmltoimage.exe
wkhtmltopdf.exe wkhtmltox.dll

有人对解决这个问题有什么想法或建议吗？

在smarterasp中部署后Rotativa.AspNetCore无法正常工作
