【问题描述】：

我已将数据发送到服务器，希望验证收据并收到格式错误的响应 (21002)。我发送到 iTunes 的 json 在 JSONlint.org 中验证，如下所示：

知道我做错了什么吗？我的斯威夫特如下：

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)

【问题讨论】：

您找到解决方案了吗？

【参考方案1】：

此代码可能对您有所帮助：

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()

【参考方案2】：

问题在于您的 URL 编码。我遇到了同样的问题，这就是我在 Swift 2.3 中修复它的方式：

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。

【参考方案3】：

您的 base64 收据数据已损坏。我尝试使用NSJSONSerialization.JSONObjectWithData(_:options:) 直接解码该字符串，以及NSData(base64EncodedString:options:)，如果您不通过.IgnoreUnknownCharacters，它们将返回nil。

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，所以它必须只是收据数据 - 尝试生成新收据。

【参考方案4】：

我遇到了这个问题，并在 Base64 编码中发现了 + 在他们到我的服务器的过程中被空格替换。在 postdata 中正确编码它们（如%2B）解决了这个问题。
