我有一个下载功能,其中的想法是,当用户单击一个按钮时,它会对一个函数执行ajax调用,该函数将创建一个包含用户正在查看的所有信息的csv文件,并将该文件作为下载。我有服务器功能创建一个csv文件,但我不知道如何下载。这是我的服务器端代码:
function download(customerOrderId) {
$.ajax({
url: insite.core.actionPrefix + '/Checkout/Download/?customerOrderId=' + customerOrderId,
type: 'Post',
contentType: "application/json; charset=utf-8",
async: false,
cache: false,
success: function (data) {
alert("downloaded");
},
error: function (ex) {
console.log(ex);
}
});
}
这是ajax方法:
OFFSET
在ajax调用成功的过程中,我检查了" data"的值。它有信息,但我不知道如何下载。收到数据后我该怎么办?

你能不能通过像这样的href下载它?
public FileContentResult Download(Guid customerOrderId)
{
// your code
var response = new FileContentResult(bytes, "text/csv");
response.FileDownloadName = filename;
return response;
}
链接:
<a href="Checkout/Download/?customerOrderId=someId">Download</a>

您可以将文件存储在服务器上并发送带响应的URL。然后在ajax成功函数window.location = data.URL
答案 2 :(得分:0)
Venerik也有一个有效的答案,但是与你当前的实施保持一致,我建议如下。
将文件保存到服务器后,可以返回URL的字符串。然后在成功时进行窗口位置重定向。我删除了变量赋值,因为除了发送到方法之外没有其他任何操作。
这里我们编写文件并返回字符串。您需要调整return
以匹配您的网站信息等。
public ActionResult Download(Guid customerOrderId)
{
var order = this.UnitOfWork.GetRepository<CustomerOrder>().Get(customerOrderId);
var csv = new StringBuilder();
csv.AppendLine("Customer,Bill To Name,Ship To Name,Patient,Order#,Order Date," +
"Line,Item#,Item Description,Qty,UOM,Price,Ext Price,Carrier," +
"Notes,Purchase Order");
foreach (var cartLine in order.OrderLines)
{
//Customer,Bill To Name,Ship To Name,Patient,Order#,Order Date," +
//"Line,Item#,Item Description,Qty,UOM,Price,Ext Price,Carrier," +
//"Notes,Purchase Order
csv.AppendLine(string.Format("{0},{1},{2},{3},{4},{5},{6},{7},{8},{9},{10},{11},{12},{13},{14},{15}",
order.CustomerNumber, order.BTDisplayName, order.ShipTo.CustomerName, "", order.OrderNumber, order.OrderDate, cartLine.Line, cartLine.Product.ProductCode, cartLine.Description,
cartLine.QtyOrdered, cartLine.UnitOfMeasure, cartLine.ActualPriceDisplay, cartLine.ExtendedActualPriceDisplay, order.ShippingDisplay, order.Notes, order.CustomerPO));
}
csv.AppendLine();
csv.AppendLine("Subtotal,Shipping & Handling,Tax,Total");
csv.AppendLine(string.Format("{0},{1},{2},{3}", order.OrderSubTotalDisplay, order.ShippingAndHandling, order.TotalSalesTaxDisplay, order.OrderGrandTotalDisplay));
var filename = "MSD-Order-" + orderNum + ".csv";
using (StreamWriter sw = File.CreateText(Server.MapPath("~/files/" + filename))
{
sw.Write(csv.ToString());
}
// adjust your url accordingly to match the directory to which you saved
// '/files/' corresponds to where you did the File.CreateText
// returning Content in an ActionResult defaults to text
return Content("http://foo.com/files/" + filename);
}
在您的AJAX方法中更新您的成功函数以重定向将提示下载的页面:
function download(customerOrderId) {
$.ajax({
url: insite.core.actionPrefix + '/Checkout/Download/?customerOrderId=' + customerOrderId,
type: 'Post',
contentType: "application/json; charset=utf-8",
async: false,
cache: false,
success: function (data) {
window.location.href = data;
},
error: function (ex) {
console.log(ex);
}
});
}
