我有一个c#服务器为vue网站提供服务。在服务器上，我有一个文件要传输到客户端。目前，服务器托管在本地，但稍后将转移到azure。
为了获得文件，我有以下c#函数：
[Microsoft.AspNetCore.Mvc.Route("api/BIM/GetModifiedRevitFile")]
public ActionResult GetModifiedRevitFile(string json)
{
//string tmppath = Path.GetTempPath();
string tmppath = "A:\code\Workspaces";
var FileVirtualPath = tmppath + "\result.rvt";
var fileUri = new Uri(FileVirtualPath);
var referenceUri = new Uri(System.IO.Path.GetDirectoryName(Assembly.GetEntryAssembly().Location));
FileVirtualPath = referenceUri.MakeRelativeUri(fileUri).ToString();
generateFile(FileVirtualPath) //stores the file in FileVirtualPath
var res= File(FileVirtualPath, "text/plain", Path.GetFileName(FileVirtualPath));
return res;
}
为了请求文件，我在vue中有以下javascript函数：
GetFileFromServer: function() {
var self = this;
$.ajax({
type: "GET",
timeout: 12000000,
url: 'api/BIM/GetModifiedRevitFile',
contentType: "application/json",
dataType: "text",
success: function (data) {
self.AskToStoreFile(data, self);
},
error: function (data) {
alert("failed to load data" + JSON.stringify(data));
}
});
}
然而，当我调用此函数时，我会收到以下错误(来自警报(：

其中特别重要的比特可能是CCD_ 1。我已经验证了文件相对于approt位于该位置，并试图看看如果我试图用"result.rvt"替换整个FileVirtualPath会发生什么，但这实际上没有任何区别。当我使用调试器时，res最终确实包含了一个文件，但没有修改日期，这表明实际的文件可能不存在？有人知道怎么解决这个问题吗？
所以我应该使用PhysicalFile和完整路径，而不是相对路径和File。修复此问题停止了错误。
