我有一个生成PDF的动作类.该contentType适当地设定.

public class MyAction extends ActionSupport 
{
   public String execute() {
    ...
    ...
    File report = signedPdfExporter.generateReport(xyzData, props);

    inputStream = new FileInputStream(report);
    contentDisposition = "attachment=\"" + report.getName() + "\"";
    contentType = "application/pdf";
    return SUCCESS;
   }
}

我action 通过Ajax调用来调用它.我不知道将此流传递给浏览器的方法.我尝试过一些东西,但没有任何效果.

$.ajax({
    type: "POST",
    url: url,
    data: wireIdList,
    cache: false,
    success: function(response)
    {
        alert('got response');
        window.open(response);
    },
    error: function (XMLHttpRequest, textStatus, errorThrown) 
    {
        alert('Error occurred while opening fax template' 
              + getAjaxErrorString(textStatus, errorThrown));
    }
});

以上给出了错误:

您的浏览器发送了此服务器无法理解的请求.

我从WebAPI控制器返回一个文件.Content-Disposition标头值自动设置为"attachment".例如:

性格:依恋; 文件名= "30956.pdf"; 文件名*= UTF-8''30956.pdf

当它设置为附件时,浏览器将要求保存文件而不是打开它.我想打开它.

如何将其设置为"内联"而不是"附件"？

我正在使用此方法发送文件:

public IActionResult GetDocument(int id)
{
    var filename = $"folder/{id}.pdf";
    var fileContentResult = new FileContentResult(File.ReadAllBytes(filename), "application/pdf")
    {
        FileDownloadName = $"{id}.pdf"
    };
    // I need to delete file after me
    System.IO.File.Delete(filename);

    return fileContentResult;
}

我在ASP.Net核心中创建了Wep API以返回PDF.这是我的代码:

public HttpResponseMessage Get(int id)
{
    var response = new HttpResponseMessage(System.Net.HttpStatusCode.OK);           
    var stream = new System.IO.FileStream(@"C:\Users\shoba_eswar\Documents\REquest.pdf", System.IO.FileMode.Open);
    response.Content = new StreamContent(stream);
    response.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment");
    response.Content.Headers.ContentDisposition.FileName = "NewTab";
    response.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/pdf");
    return response;
}

但它只返回JSON响应:

{
   "version":{
      "major":1,
      "minor":1,
      "build":-1,
      "revision":-1,
      "majorRevision":-1,
      "minorRevision":-1
   },
   "content":{
      "headers":[
         {
            "key":"Content-Disposition",
            "value":[
               "attachment; filename=NewTab"
            ]
         },
         {
            "key":"Content-Type",
            "value":[
               "application/pdf"
            ]
         }
      ]
   },
   "statusCode":200,
   "reasonPhrase":"OK",
   "headers":[

   ],
   "requestMessage":null,
   "isSuccessStatusCode":true
}

我在这里做错了吗？
