My previous question: How to return file from ASP.net 5 web api

我试图返回一个文件从网页API POST请求的响应。

I am trying to return a file as the response from Web API POST request.

我使用dnx451框架和RC1-最终版本。控制方法：

I'm using dnx451 framework and rc1-final build. Controller method:

[HttpPost("")]
public ActionResult Post([FromBody]DocumentViewModel vm)
{
    try
    {
        if (ModelState.IsValid)
        {

            var Document = _repository.GetDocumentByGuid(vm.DocumentGuid, User.Identity.Name);
            var Params = Helper.ClientInputToRealValues(vm.Parameters, Document.DataFields);
            var file = Helper.GeneratePdf(Helper.InsertValues(Params, Document.Content));
            FileStream stream = new FileStream(file,FileMode.Open);

            return File(stream, "application/pdf", "test.pdf");

        }

    }
    catch (Exception ex)
    {
        Response.StatusCode = (int)HttpStatusCode.BadRequest;
        return null;
    }
    Response.StatusCode = (int)HttpStatusCode.BadRequest;
    return null;

}

至于结果我得到一个名为回应的文件。将其保存为PDF格式后，我尝试打开它，它说，它已损坏。希望你能帮助我。我使用的邮差作为测试客户端。

As result I get a file with name "response". After saving it as pdf i try to open it, and it says it is damaged. Hope you can help me. I am using Postman as test client.

感谢

推荐答案

请参阅其他职位我的回答：返回文件作为响应

Please see my answer in the other post: Return file as response

有关参考，我觉得这适合您的需要：

For reference, I think this fits your needs:

public FileResult TestDownload()
{
    HttpContext.Response.ContentType = "application/pdf";
    FileContentResult result = new FileContentResult(System.IO.File.ReadAllBytes("YOUR PATH TO PDF"), "application/pdf")
    {
        FileDownloadName = "test.pdf"
    };

    return result;                                
}
