我无法通过Web API的get调用从服务器成功下载文件。下载似乎已经开始,但是Chrome会抛出以下错误:
"Resource interpreted as Document but transferred with MIME type application/zip"
Firefox没有报错,但下载仍然失败。
在以下设置中,我做错了什么?:
[HttpGet, Route("api/extractor/downloadresults")]
public HttpResponseMessage DownloadResultFiles()
{
int contentLength = 0;
this.ResultFiles.ForEach(f => contentLength = contentLength + f.FileSize);
var streamContent = new PushStreamContent((outputStream, httpContext, transportContent) =>
{
...zip files...
});
streamContent.Headers.ContentType = new MediaTypeHeaderValue("application/zip");
streamContent.Headers.ContentLength = contentLength;
streamContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = "result.zip"
};
var response = Request.CreateResponse();
response.StatusCode = HttpStatusCode.OK;
response.Content = streamContent;
}
我通过以下方式触发下载:
window.location.href = "api/extractor/downloadresults";
使用下列头部信息:
