在新选项卡上的 IE11 中打开 PDF 而不提示 - mssaveoropenblob

Open PDF in IE11 on new tab without prompting - mssaveoropenblob(在新选项卡上的 IE11 中打开 PDF 而不提示 - mssaveoropenblob)

问题描述

我们正在迁移一个 ASP.NET MVC 应用程序，该应用程序具有通过 FileContentResult 在新选项卡中打开 PDF 的功能.

We are migrating an ASP.NET MVC application, which had the feature to open PDF in a new tab via FileContentResult.

return new FileContentResult(byteArray, "application/pdf");

现在我们正在将此应用程序迁移到 React，并从 API(服务器端)返回响应，如下所示:-

Now we are migrating this app to React and from from the API (server side), we are sending back the response as below :-

response.Content = new ByteArrayContent(pdfByteArray);
response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/pdf");

在 React UI 方面，我们使用如下响应:-

On the React UI side, we are using the response as below :-

postData(POST_API_ENDPOINT, requestData, ((err, data) => {
  if (data.ok) {
     data.blob().then(function(myBlob) {
         if (window.navigator && window.navigator.msSaveOrOpenBlob) {
            return window.navigator.msSaveOrOpenBlob(myBlob, "sample.pdf");
         }
         else {
           var objectURL = URL.createObjectURL(myBlob);
           return window.open(objectUrl);
          }
        });
      }
  }));

现在，我知道 msSaveOrOpenBlob 总是会提示用户在 IE11 中打开/保存".如果我需要在没有提示的情况下在其他选项卡中打开 PDF，我还有哪些其他选择?

Now, i understand that msSaveOrOpenBlob would always prompt the user to "open/save" within IE11. What other options do i have if i need to open the PDF in a different tab without the prompts?

我想还有另一种方法可以通过以下方式做到这一点，但网址长度再次限制了这一点.

I guess there is another way to do that via the below manner, but again the URL length limits that.

window.open("data:application/pdf;base64, " + base64EncodedPDF);

推荐答案

IE 不允许我们在新选项卡中打开数据 URL(可能是出于安全原因)并且没有解决方法 - 之前遇到过同样的问题.

IE does not allow us to open Data URL in new tab (possibly security reason) and there no workaround - faced same issue earlier.

我们使用 msSaveOrOpenBlob - 找不到替代方案.

We use msSaveOrOpenBlob - found no alternative.
