验证 appReceiptStoreURL 返回 21002 状态

Question

我创建了一个类来处理应用内购买以及收据的验证。不久前，我曾经在 SKPaymentTransaction 上使用 transactionReceipt 属性，但我已经更新了相当数量的代码，现在在 [NSBundle mainBundle] 上使用 appStoreReceiptURL。

基本上，我的收据似乎以可接受的方式发送到 Apple 的服务器，但我不断收到 21002 的状态代码。在自动续订订阅中，我知道这意味着收据的格式不可接受，但是我不知道这种状态对于应用内购买收据意味着什么。

这是验证收据的本地方法：

/**
 *  Validates the receipt.
 *
 *  @param  transaction                 The transaction triggering the validation of the receipt.
 */
- (void)validateReceiptForTransaction:(SKPaymentTransaction *)transaction
{
    //  get the product for the transaction
    IAPProduct *product                 = self.internalProducts[transaction.payment.productIdentifier];

    //  get the receipt as a base64 encoded string
    NSData *receiptData                 = [[NSData alloc] initWithContentsOfURL:[NSBundle mainBundle].appStoreReceiptURL];
    NSString *receipt                   = [receiptData base64EncodedStringWithOptions:kNilOptions];
    NSLog(@"Receipt: %@", receipt);

    //  determine the url for the receipt verification server
    NSURL *verificationURL              = [[NSURL alloc] initWithString:IAPHelperServerBaseURL];
    verificationURL                     = [verificationURL URLByAppendingPathComponent:IAPHelperServerReceiptVerificationComponent];
    NSMutableURLRequest *urlRequest     = [[NSMutableURLRequest alloc] initWithURL:verificationURL];
    urlRequest.HTTPMethod               = @"POST";
    NSDictionary *httpBody              = @{@"receipt"      : receipt,
                                            @"sandbox"      : @(1)};
    urlRequest.HTTPBody                 = [NSKeyedArchiver archivedDataWithRootObject:httpBody];
    [NSURLConnection sendAsynchronousRequest:urlRequest
                                       queue:[[NSOperationQueue alloc] init]
                           completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError)
    {
        //  create a block to be called whenever a filue is hit
        void (^failureBlock)(NSString *failureMessage)          = ^void(NSString *failureMessage)
        {
            [[NSOperationQueue mainQueue] addOperationWithBlock:
            ^{
                //  log the failure message
                NSLog(@"%@", failureMessage);
                //  if we have aready tried refreshing the receipt then we close the transaction to avoid loops
                if (self.transactionToValidate)
                    product.purchaseInProgress  = NO,
                    [[SKPaymentQueue defaultQueue] finishTransaction:transaction],
                    [self notifyStatus:@"Validation failed." forProduct:product],
                    self.transactionToValidate  = nil;
                //  if we haven't tried yet, we'll refresh the receipt and then attempt a second validation
                else
                    self.transactionToValidate  = transaction,
                    [self refreshReceipt];
            }];
        };

        //  check for an error whilst contacting the server
        if (connectionError)
        {
            failureBlock([[NSString alloc] initWithFormat:@"Failure connecting to server: %@", connectionError]);
            return;
        }

        //  cast the response appropriately
        NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;

        //  parse the JSON
        NSError *jsonError;
        NSDictionary *json              = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&jsonError];

        //  if the data did not parse correctly we fail out
        if (!json)
        {
            NSString *responseString        = [NSHTTPURLResponse localizedStringForStatusCode:httpResponse.statusCode];
            NSString *failureMessage        = [[NSString alloc] initWithFormat:@"Failure parsing JSON: %@\nServer Response: %@ (%@)",
                                               data, responseString, @(httpResponse.statusCode)];
            failureBlock(failureMessage);
            return;
        }

        //  if the JSON was successfully parsed pull out status code to check for verification success
        NSInteger statusCode            = [json[@"status"] integerValue];
        NSString *errorDescription      = json[@"error"];
        //  if the verification did not succeed we fail out
        if (statusCode != 0)
        {
            NSString *failureMessage    = [[NSString alloc] initWithFormat:@"Failure verifying receipt: %@", errorDescription];
            failureBlock(failureMessage);
        }
        //  otherwise we have succeded, yay
        else
            NSLog(@"Successfully verified receipt."),
            [self provideContentForCompletedTransaction:transaction productIdentifier:transaction.payment.productIdentifier];

    }];
}

服务器上重要的 PHP 函数是这样做的：

    /**
     *  Validates a given receipt and returns the result.
     *
     *  @param  receipt             Base64-encoded receipt.
     *  @param  sandbox             Boolean indicating whether to use sandbox servers or production servers.
     *
     *  @return Whether the reciept is valid or not.
     */
    function validateReceipt($receipt, $sandbox)
    {
        //  determine url for store based on if this is production or development
        if ($sandbox)
            $store                  = 'https://sandbox.itunes.apple.com/verifyReceipt';
        else
            $store                  = 'https://buy.itunes.apple.com/verifyReceipt';

        //  set up json-encoded dictionary with receipt data for apple receipt validator
        $postData                   = json_encode(array('receipt-data'  => $receipt));

        //  use curl library to perform web request
        $curlHandle                 = curl_init($store);
        //  we want results returned as string, the request to be a post, and the json data to be in the post fields
        curl_setopt($curlHandle, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($curlHandle, CURLOPT_POST, true);
        curl_setopt($curlHandle, CURLOPT_POSTFIELDS, $postData);
        $encodedResponse            = curl_exec($curlHandle);
        curl_close($curlHandle);

        //  if we received no response we return the error
        if (!$encodedResponse)
            return result(ERROR_VERIFICATION_NO_RESPONSE, 'Payment could not be verified - no response data. This was sandbox? ' . ($sandbox ? 'YES' : 'NO'));

        //  decode json response and get the data
        $response                   = json_decode($encodedResponse);
        $status                     = $response->{'status'};
        $decodedReceipt             = $response->{'receipt'};

        //  if status code is not 0 there was an error validation receipt
        if ($status)
            return result(ERROR_VERIFICATION_FAILED, 'Payment could not be verified (status = ' . $status . ').');

        //  log the returned receipt from validator
        logToFile(print_r($decodedReceipt, true));

        //  pull out product id, transaction id and original transaction id from infro trurned by apple
        $productID                  = $decodedReceipt->{'product_id'};
        $transactionID              = $decodedReceipt->{'transaction_id'};
        $originalTransactionID      = $decodedReceipt->{'original_transaction_id'};

        //  make sure product id has expected prefix or we bail
        if (!beginsWith($productID, PRODUCT_ID_PREFIX))
            return result(ERROR_INVALID_PRODUCT_ID, 'Invalid Product Identifier');

        //  get any existing record of this transaction id from our database
        $db                         = Database::get();
        $statement                  = $db->prepare('SELECT * FROM transactions WHERE transaction_id = ?');
        $statement->bindParam(1, $transactionID, PDO::PARAM_STR, 32);
        $statement->execute();

        //  if we have handled this transaction before return a failure
        if ($statement->rowCount())
        {
            logToFile("Already processed $transactionID.");
            return result(ERROR_TRANSACTION_ALREADY_PROCESSED, 'Already processed this transaction.');
        }

        //  otherwise we insert this new transaction into the database
        else
        {
            logToFile("Adding $transactionID.");
            $statement              = $db->prepare('INSERT INTO transactions(transaction_id, product_id, original_transaction_id) VALUES (?, ?, ?)');
            $statement->bindParam(1, $transactionID, PDO::PARAM_STR, 32);
            $statement->bindParam(2, $productID, PDO::PARAM_STR, 32);
            $statement->bindParam(3, $originalTransactionID, PDO::PARAM_STR, 32);
            $statement->execute();
        }


        return result(SUCCESS);
    }

实际执行的 PHP 脚本是：

    $receipt            = $_POST['receipt'];
    $sandbox            = $_POST['sandbox'];
    $returnValue        = validateReceipt($receipt, $sandbox);

    header('content-type: application/json; charset=utf-8');

    echo json_encode($returnValue);

Answer 1

比较你的 PHP 和我的（我知道这可行）是很困难的，因为我使用的是 HTTPRequest 而不是原始的 curl API。但是，在我看来，您将“{receipt-data:..}”JSON 字符串设置为 POST 数据中的一个 field 而不是原始 POST 数据本身，这就是我的代码在做。

curl_setopt($curlHandle, CURLOPT_POST, true);
curl_setopt($curlHandle, CURLOPT_POSTFIELDS, $postData); // Possible problem
$encodedResponse = curl_exec($curlHandle);

相比：

$postData = '{"receipt-data" : "'.$receipt.'"}'; // yay one-off JSON serialization!
$request = new HTTPRequest('https://sandbox.itunes.apple.com/verifyReceipt', HTTP_METH_POST);
$request->setBody($postData); // Relevant difference...
$request->send();
$encodedResponse = $request->getResponseBody();

我已经稍微更改了我的变量名，以使它们与您的示例相匹配。

代码 21002 表示“receipt-data 属性中的数据格式错误或丢失。”

你可以在 https://developer.apple.com/library/archive/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html

下面的代码是我的appstore应用内verifyRecepip类，需要GuzzleHttp，可以通过composer require guzzlehttp/guzzlehttps://github.com/guzzle/guzzle安装

我认为 Morteza M 是正确的。我做了一个测试，得到了回复（JSON），比如：

{
'status':
'environment': 'Sandbox'
  'receipt':
  {
    'download_id':
    ....
    'in_app":
    {
      'product_id':
      ....
    }
    ....
  }
}
