我正試圖編寫一個MVC3應用程序，當他們掃描QR碼時，動態生成一個vCard（.vcf）文件，供移動設備上的人下載。我找到一個示例here來構建和返回vCard。經過一些操作後，我可以在我的臺式機上運行它，但是每次我嘗試在移動設備上下載文件時，下載都會失敗。我曾以爲它發送的頭文件有問題，所以我做了一些挖掘，並在Android here的HTTP頭文件中找到了一些有用的信息。不幸的是，即使調整標題也沒有改變任何東西。MVC3電子名片在移動設備上下載失敗
第一部分是控制器，稍後這將採取URL參數。保持測試簡單。
public class APIController : Controller
{
public vCardResult vCard()
{
vCard card = new vCard
{
FirstName = "First",
LastName = "Last",
StreetAddress = "70 Street Adr.",
City = "Atlanta",
State = "GA",
CountryName = "United States",
Mobile = "5558675309",
Organization = "MyCompany",
HomePage = "www.Google.com",
JobTitle = "Software Developer",
Zip = "30318",
Email = "[email protected]",
};
return new vCardResult(card);
}
這裏是電子名片型號
public class vCard
{
//I cut out the properties to save space
public override string ToString()
{
var builder = new StringBuilder();
builder.AppendLine("BEGIN:VCARD");
builder.AppendLine("VERSION:2.1");
builder.AppendLine("FN:" + FirstName + " " + LastName);
builder.AppendLine("N:" + LastName + ";" + FirstName);
builder.AppendLine("TEL;CELL:" + Mobile);
builder.AppendLine("TEL:");
builder.AppendLine("EMAIL;INTERNET:" + Email);
builder.AppendLine("TEL;FAX:");
builder.AppendLine("TITLE:" + JobTitle);
builder.AppendLine("ORG:" + Organization);
builder.AppendLine("ADR:;;" + StreetAddress + ";" + City + ";" + ";" + Zip + ";");
builder.AppendLine("REV:20120730T15034z");
builder.AppendLine("END:VCARD");
return builder.ToString();
}
}
最後是行動的結果
public class vCardResult : ActionResult
{
private vCard _card;
protected vCardResult() { }
public vCardResult(vCard card)
{
_card = card;
}
public override void ExecuteResult(ControllerContext context)
{
var response = context.HttpContext.Response;
response.ContentType = "text/vcard";
response.AddHeader("Content-Disposition", "attachment; fileName=\"" + _card.FirstName + "_" + _card.LastName + ".VCF\"");
var cardString = _card.ToString();
var inputEncoding = Encoding.Default;
var outputEncoding = Encoding.GetEncoding("windows-1257");
var cardBytes = inputEncoding.GetBytes(cardString);
var outputBytes = Encoding.Convert(inputEncoding,
outputEncoding, cardBytes);
response.OutputStream.Write(outputBytes, 0, outputBytes.Length);
}
}
不是從我剛纔列舉的例子太多不同，但我想至少拿到這個在我進一步走得太遠之前運作正常。
我檢查了服務器響應類似的工作系統（我沒有訪問源代碼）的響應，我沒有看到很多差異，所以我不確定他們的vCard爲什麼會打開電話的聯繫人列表添加爲新聯繫人，並且我的下載失敗。答覆如下。
