使用Swift退货代码21002进行应用内收据验证

我已将数据发送到服务器，希望验证收据，但收到的响应格式不正确（21002）。我发送给iTunes的json在JSONlint.org中进行验证，如下所示：

知道我做错了什么吗？我的Swift如下：

var receiptUrl = NSBundle.mainBundle().appStoreReceiptURL;
var receipt: NSData = NSData.dataWithContentsOfURL(receiptUrl, options: nil, error: nil)
var receiptdata:NSString = receipt.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.fromRaw(0)!)


    var requestContents:NSDictionary = ["receipt-data": receiptdata];

    var jsonString:NSData = NSJSONSerialization.dataWithJSONObject(requestContents, options:nil,error:nil);


    var dta:NSString = NSString(data: jsonString, encoding: NSUTF8StringEncoding)


    request.HTTPBody = dta.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true) 

    request.HTTPMethod = "POST"
    request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")


    // send the request
    NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &error)

---

您的base64回执数据已损坏。我尝试使用

NSJSONSerialization.JSONObjectWithData（uu2;：选项：）

直接解码该字符串，以及

NSData（base64EncodedString:options：）

，如果不传递

，它们将返回nil。忽略未知字符

---

我在从App Store应用程序获得的收据上测试了您的其余代码，它工作正常，因此它必须是收据数据-尝试生成新收据。

此代码可能会帮助您：

func validateRecipt(){
    var response: NSURLResponse?
    var error: NSError?

    var recuptUrl = NSBundle.mainBundle().appStoreReceiptURL
    var receipt: NSData = NSData(contentsOfURL:recuptUrl!, options: nil, error: nil)!



    //https://buy.itunes.apple.com/verifyReceipt
    var request = NSMutableURLRequest(URL: NSURL(string: "https://sandbox.itunes.apple.com/verifyReceipt")!, cachePolicy: NSURLRequestCachePolicy.UseProtocolCachePolicy, timeoutInterval: 10)

    var session = NSURLSession.sharedSession()
    request.HTTPMethod = "POST"
    var receiptdata:NSString = receipt.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.EncodingEndLineWithLineFeed)
    NSLog("%@",receiptdata)
    var payload:NSString = "{\"receipt-data\" : \"\(receiptdata)\"}"
    var payloadData = payload.dataUsingEncoding(NSUTF8StringEncoding)
    var err: NSError?

    request.HTTPBody = payloadData

    var task = session.dataTaskWithRequest(request, completionHandler:
        {data, response, error -> Void in
            var err: NSError?
            var json = NSJSONSerialization.JSONObjectWithData(data, options: .MutableLeaves, error: &err) as? NSDictionary

            if(err != nil) {
                println(err!.localizedDescription)
                let jsonStr = NSString(data: data, encoding: NSUTF8StringEncoding)
                println("Error could not parse JSON: '\(jsonStr)'")
            }
            else {
                if let parseJSON = json {
                    println("Recipt \(parseJSON)")
                }
                else {
                    let jsonStr = NSString(data: data, encoding: NSUTF8StringEncoding)
                    println("Recipt Error: \(jsonStr)")
                }
            }
    })

    task.resume()

}

我遇到了这个问题，并发现Base64编码中的

+

在到达我的服务器的过程中被空格替换。在postdata中正确地编码它们（如

%2B

）解决了问题。

问题在于URL编码。我也有同样的问题，这是我如何在Swift 2.3中修复的：

extension String {
    // correct URL encoding
    var URLEncoded: String {
        let allowedCharacters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-._~"
        let allowedCharSet = NSCharacterSet(charactersInString: allowedCharacters)
        let encodedString = self.stringByAddingPercentEncodingWithAllowedCharacters(allowedCharSet)
        return encodedString ?? self
    } 
}

---

然后在验证之前使用

yourReceipt.URLEncoded

你找到解决办法了吗？
