use*_*962 5 in-app-purchase ios receipt-validation swift swift3
我正在Swift 3中开发一个iOS应用程序,并尝试按照本教程实现收据验证:http://savvyapps.com/blog/how-setup-test-auto-renewable-subscription-ios-app.但是,该教程似乎是使用早期版本的Swift编写的,因此我不得不进行一些更改.这是我的receiptValidation()函数:
func receiptValidation() {
let receiptPath = Bundle.main.appStoreReceiptURL?.path
if FileManager.default.fileExists(atPath: receiptPath!){
var receiptData:NSData?
do{
receiptData = try NSData(contentsOf: Bundle.main.appStoreReceiptURL!, options: NSData.ReadingOptions.alwaysMapped)
}
catch{
print("ERROR: " + error.localizedDescription)
}
let receiptString = receiptData?.base64EncodedString(options: NSData.Base64EncodingOptions(rawValue: 0))
let postString = "receipt-data=" + receiptString! + "&password=" + SUBSCRIPTION_SECRET
let storeURL = NSURL(string:"https://sandbox.itunes.apple.com/verifyReceipt")!
let storeRequest = NSMutableURLRequest(url: storeURL as URL)
storeRequest.httpMethod = "POST"
storeRequest.httpBody = postString.data(using: .utf8)
let session = URLSession(configuration:URLSessionConfiguration.default)
let task = session.dataTask(with: storeRequest as URLRequest) { data, response, error in
do{
let jsonResponse:NSDictionary = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as! NSDictionary
let expirationDate:NSDate = self.expirationDateFromResponse(jsonResponse: jsonResponse)!
self.updateIAPExpirationDate(date: expirationDate)
}
catch{
print("ERROR: " + error.localizedDescription)
}
}
task.resume()
}
}
当我尝试调用expirationDateFromResponse()方法时,问题出现了.事实证明,传递给此方法的jsonResponse只包含:status = 21002;.我查了一下这意味着"收据数据属性中的数据格式错误或丢失." 但是,我正在测试的设备有一个活动的沙盒订阅产品,除了这个问题,订阅似乎正常工作.还有什么我还需要做的事情,以确保将正确读取和编码receiptData值,或者可能导致此问题的其他一些问题？
编辑:
我尝试了另一种设置storeRequest.httpBody的方法:
func receiptValidation() {
let receiptPath = Bundle.main.appStoreReceiptURL?.path
if FileManager.default.fileExists(atPath: receiptPath!){
var receiptData:NSData?
do{
receiptData = try NSData(contentsOf: Bundle.main.appStoreReceiptURL!, options: NSData.ReadingOptions.alwaysMapped)
}
catch{
print("ERROR: " + error.localizedDescription)
}
let receiptString = receiptData?.base64EncodedString(options: NSData.Base64EncodingOptions(rawValue: 0)) //.URLEncoded
let dict = ["receipt-data":receiptString, "password":SUBSCRIPTION_SECRET] as [String : Any]
var jsonData:Data?
do{
jsonData = try JSONSerialization.data(withJSONObject: dict, options: .prettyPrinted)
}
catch{
print("ERROR: " + error.localizedDescription)
}
let storeURL = NSURL(string:"https://sandbox.itunes.apple.com/verifyReceipt")!
let storeRequest = NSMutableURLRequest(url: storeURL as URL)
storeRequest.httpMethod = "POST"
storeRequest.httpBody = jsonData!
let session = URLSession(configuration:URLSessionConfiguration.default)
let task = session.dataTask(with: storeRequest as URLRequest) { data, response, error in
do{
let jsonResponse:NSDictionary = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as! NSDictionary
let expirationDate:NSDate = self.expirationDateFromResponse(jsonResponse: jsonResponse)!
self.updateIAPExpirationDate(date: expirationDate)
}
catch{
print("ERROR: " + error.localizedDescription)
}
}
task.resume()
}
}
但是,当我使用此代码运行应用程序时,它会在到达该行时挂起jsonData = try JSONSerialization.data(withJSONObject: dict, options: .prettyPrinted).它甚至没有进入捕获块,它只是停止做任何事情.从我在网上看到的,其他人似乎在使用JSONSerialization.data在Swift 3中设置请求httpBody时遇到了麻烦.
它与Swift 4一起正常工作
func receiptValidation() {
let SUBSCRIPTION_SECRET = "yourpasswordift"
let receiptPath = Bundle.main.appStoreReceiptURL?.path
if FileManager.default.fileExists(atPath: receiptPath!){
var receiptData:NSData?
do{
receiptData = try NSData(contentsOf: Bundle.main.appStoreReceiptURL!, options: NSData.ReadingOptions.alwaysMapped)
}
catch{
print("ERROR: " + error.localizedDescription)
}
//let receiptString = receiptData?.base64EncodedString(options: NSData.Base64EncodingOptions(rawValue: 0))
let base64encodedReceipt = receiptData?.base64EncodedString(options: NSData.Base64EncodingOptions.endLineWithCarriageReturn)
print(base64encodedReceipt!)
let requestDictionary = ["receipt-data":base64encodedReceipt!,"password":SUBSCRIPTION_SECRET]
guard JSONSerialization.isValidJSONObject(requestDictionary) else { print("requestDictionary is not valid JSON"); return }
do {
let requestData = try JSONSerialization.data(withJSONObject: requestDictionary)
let validationURLString = "https://sandbox.itunes.apple.com/verifyReceipt" // this works but as noted above it's best to use your own trusted server
guard let validationURL = URL(string: validationURLString) else { print("the validation url could not be created, unlikely error"); return }
let session = URLSession(configuration: URLSessionConfiguration.default)
var request = URLRequest(url: validationURL)
request.httpMethod = "POST"
request.cachePolicy = URLRequest.CachePolicy.reloadIgnoringCacheData
let task = session.uploadTask(with: request, from: requestData) { (data, response, error) in
if let data = data , error == nil {
do {
let appReceiptJSON = try JSONSerialization.jsonObject(with: data)
print("success. here is the json representation of the app receipt: \(appReceiptJSON)")
// if you are using your server this will be a json representation of whatever your server provided
} catch let error as NSError {
print("json serialization failed with error: \(error)")
}
} else {
print("the upload task returned an error: \(error)")
}
}
task.resume()
} catch let error as NSError {
print("json serialization failed with error: \(error)")
}
}
}
我更新了@ user3726962的代码,删除了不必要的NS'es和"崩溃运算符".现在看起来应该更像Swift 3.
在使用此代码之前,请注意Apple不建议直接[设备] < - > [Apple服务器]验证并要求执行[设备] < - > [您的服务器] < - > [Apple服务器].仅在您不害怕将应用程序内购买入侵时使用.
更新:使功能通用:它将尝试首先使用Production验证收据,如果失败 - 它将重复使用Sandbox.它有点笨重,但应该是独立的,独立于第三方.

request.start()
}
这适用于自动续订订阅.尚未使用其他类型的订阅进行测试.如果它适用于某些其他订阅类型,请发表评论.

Yasin Aktimur，感谢您的回答，太棒了。但是，查看有关此的 Apple 文档，他们说要在单独的队列上连接到 iTunes。所以它应该是这样的：
func receiptValidation() {
let SUBSCRIPTION_SECRET = "secret"
let receiptPath = Bundle.main.appStoreReceiptURL?.path
if FileManager.default.fileExists(atPath: receiptPath!){
var receiptData:NSData?
do{
receiptData = try NSData(contentsOf: Bundle.main.appStoreReceiptURL!, options: NSData.ReadingOptions.alwaysMapped)
}
catch{
print("ERROR: " + error.localizedDescription)
}
let base64encodedReceipt = receiptData?.base64EncodedString(options: NSData.Base64EncodingOptions.endLineWithCarriageReturn)
let requestDictionary = ["receipt-data":base64encodedReceipt!,"password":SUBSCRIPTION_SECRET]
guard JSONSerialization.isValidJSONObject(requestDictionary) else { print("requestDictionary is not valid JSON"); return }
do {
let requestData = try JSONSerialization.data(withJSONObject: requestDictionary)
let validationURLString = "https://sandbox.itunes.apple.com/verifyReceipt" // this works but as noted above it's best to use your own trusted server
guard let validationURL = URL(string: validationURLString) else { print("the validation url could not be created, unlikely error"); return }
let session = URLSession(configuration: URLSessionConfiguration.default)
var request = URLRequest(url: validationURL)
request.httpMethod = "POST"
request.cachePolicy = URLRequest.CachePolicy.reloadIgnoringCacheData
let queue = DispatchQueue(label: "itunesConnect")
queue.async {
let task = session.uploadTask(with: request, from: requestData) { (data, response, error) in
if let data = data , error == nil {
do {
let appReceiptJSON = try JSONSerialization.jsonObject(with: data, options: .allowFragments) as? NSDictionary
print("success. here is the json representation of the app receipt: \(appReceiptJSON)")
} catch let error as NSError {
print("json serialization failed with error: \(error)")
}
} else {
print("the upload task returned an error: \(error ?? "couldn't upload" as! Error)")
}
}
task.resume()
}
} catch let error as NSError {
print("json serialization failed with error: \(error)")
}
}
}
