我需要从web api控制器获取一个csv文件.我无法显示"另存为"对话框.只有文本输出显示在页面上.我试过两个,从jquery调用Export,也是普通的旧html
控制器:
[System.Web.Http.HttpGet]
public HttpResponseMessage Export()
{
StringBuilder sb = new StringBuilder();
IEnumerable<CustomerDiscount> list = this.subscriberRepository.GetSubscribers();
foreach (CustomerDiscount item in list)
{
sb.AppendFormat(
"{0};{1};{2};",
item.CustomerName,
item.CustomerNumber,
Environment.NewLine);
}
MemoryStream stream = new MemoryStream();
StreamWriter writer = new StreamWriter(stream);
writer.Write(sb.ToString());
writer.Flush();
stream.Position = 0;
HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.OK);
result.Content = new StreamContent(stream);
result.Content.Headers.ContentType =
new MediaTypeHeaderValue("text/csv");
result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment") { FileName = "Export.csv" };
return result;
}
编辑:添加此行:
result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment") { FileName = "Export.csv" };
仍然无法正常工作
我称之为:
<a id="export" href="/Relay/Billing/Export" class="btn btn-primary">Export</a>
并尝试过这样:
$("#export").click(function () {
$.post("/Relay/Billing/Export", { type: $("#discountType").val() })
.done(function (data) {
});
});
仍然没有另存为框

我不知道这是否是正确的协议,但这是我之前做过的.所以你有一个网页,你将从中调用一个API来响应文件,它应该由浏览器的另存为对话框来处理.
HTML:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript">
function save() {
window.open('http://localhost:45719/api/home?id=12', '_blank', '');
}
</script>
</head>
<body>
<a class="btn btn-primary" onclick="save()">Export</a>
</body>
</html>
那个行动:
public HttpResponseMessage Get(int id)
{
MemoryStream stream = new MemoryStream();
StreamWriter writer = new StreamWriter(stream);
writer.Write("Hello, World!");
writer.Flush();
stream.Position = 0;
HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.OK);
result.Content = new StreamContent(stream);
result.Content.Headers.ContentType = new MediaTypeHeaderValue("text/csv");
result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment") { FileName = "Export.csv" };
return result;
}
这对我来说最适合Chrome和Firefox.
