我正在验证我的iosin app purchase
我的服务器上使用的收据C#
网络服务
我通过在 Xcode 中执行以下操作获得了字符串形式的收据:
- (void) completeTransaction: (SKPaymentTransaction *)transaction
{
NSString* receiptString = [[NSString alloc] initWithString:transaction.payment.productIdentifier];
NSLog(@"%@",receiptString);
NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];
NSString *jsonObjectString = [receipt base64EncodedStringWithOptions:0];
}
我正在将该字符串(收据)发送到我的C#
Web 服务作为参数。
这是我的网络服务方法:
[WebMethod(Description = "Purchase Item Verify")]
public string PurchaseItem(string receiptData)
{
string returnmessage = "";
try
{
var json = "{ 'receipt-data': '" + receiptData + "'}";
ASCIIEncoding ascii = new ASCIIEncoding();
byte[] postBytes = Encoding.UTF8.GetBytes(json);
HttpWebRequest request;
request = WebRequest.Create("https://sandbox.itunes.apple.com/verifyReceipt") as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = postBytes.Length;
Stream postStream = request.GetRequestStream();
postStream.Write(postBytes, 0, postBytes.Length);
postStream.Close();
var sendresponse = (HttpWebResponse)request.GetResponse();
string sendresponsetext = "";
using (var streamReader = new StreamReader(sendresponse.GetResponseStream()))
{
sendresponsetext = streamReader.ReadToEnd();
}
returnmessage = sendresponsetext;
}
catch (Exception ex)
{
ex.Message.ToString();
}
return returnmessage;
}
它总会回来{"status":21002}
。
我已经找了两天了,还是没找到解决办法。有人可以帮助我,我错了什么?
**我正在沙箱上进行测试,这就是我使用沙箱 URL 的原因。我可以在我的应用程序中验证交易收据。
我得到了解决方案
对我有用的最终代码是:
public string PurchaseItem(string receiptData)
{
string returnmessage = "";
try
{
// var json = "{ 'receipt-data': '" + receiptData + "'}";
var json = new JObject(new JProperty("receipt-data", receiptData)).ToString();
ASCIIEncoding ascii = new ASCIIEncoding();
byte[] postBytes = Encoding.UTF8.GetBytes(json);
// HttpWebRequest request;
var request = System.Net.HttpWebRequest.Create("https://sandbox.itunes.apple.com/verifyReceipt");
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = postBytes.Length;
//Stream postStream = request.GetRequestStream();
//postStream.Write(postBytes, 0, postBytes.Length);
//postStream.Close();
using (var stream = request.GetRequestStream())
{
stream.Write(postBytes, 0, postBytes.Length);
stream.Flush();
}
// var sendresponse = (HttpWebResponse)request.GetResponse();
var sendresponse = request.GetResponse();
string sendresponsetext = "";
using (var streamReader = new StreamReader(sendresponse.GetResponseStream()))
{
sendresponsetext = streamReader.ReadToEnd().Trim();
}
returnmessage = sendresponsetext;
}
catch (Exception ex)
{
ex.Message.ToString();
}
return returnmessage;
花了两天半的时间才换了一个方法。感谢上帝。
