狀態21002驗證交易收據時

Question

我試圖查看所有其他問題，而且似乎沒有任何東西可以解決此問題。我已經縮小了它的範圍，因此https://sandbox.itunes.apple.com/verifyReceipt的響應僅僅是{"status":21002}。任何幫助將不勝感激，我已經複製下面的相關代碼。

NSString *completeString = @"http://www.mysite.com/verify.php"; 

NSURL *urlForValidation = [NSURL URLWithString:completeString]; 

NSMutableURLRequest *validationRequest = [[NSMutableURLRequest alloc] initWithURL:urlForValidation]; 

[validationRequest setHTTPMethod:@"POST"]; 

NSString *strTest = [NSString stringWithFormat:@"receipt=%@", [self createEncodedString:transaction.transactionReceipt]]; 

[validationRequest setHTTPBody:[NSData dataFromBase64String:strTest]]; 

NSData *responseData = [NSURLConnection sendSynchronousRequest:validationRequest returningResponse:nil error:nil]; 

NSString *response = [[NSString alloc] initWithData: responseData encoding: NSUTF8StringEncoding]; 

NSLog(@"%@", response); 

- (NSString*) createEncodedString:(NSData*)data { 
    static char table[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz/="; 

    const int size = ((data.length + 2)/3)*4; 
    uint8_t output[size]; 

    const uint8_t* input = (const uint8_t*)[data bytes]; 
    for (int i = 0; i < data.length; i += 3) 
    { 
     int value = 0; 
     for (int j = i; j < (i + 3); j++) 
     { 
      value <<= 8; 
      if (j < data.length) 
       value |= (0xFF & input[j]); 
     } 

     const int index = (i/3) * 4; 
     output[index + 0] = table[(value >> 18) & 0x3F]; 
     output[index + 1] = table[(value >> 12) & 0x3F]; 
     output[index + 2] = (i + 1) < data.length ? table[(value >> 6) & 0x3F] : '='; 
     output[index + 3] = (i + 2) < data.length ? table[(value >> 0) & 0x3F] : '='; 
    } 

    return [[NSString alloc] initWithBytes:output length:size encoding:NSASCIIStringEncoding]; 
} 

最後這是所使用的PHP代碼：

$url = 'https://sandbox.itunes.apple.com/verifyReceipt'; 

$receipt = "{%s}" % $_POST["receipt"]; 

$purchase_encoded = base64_encode($receipt); 

$encodedData = json_encode(Array( 
    'receipt-data' => $purchase_encoded 
)); 

//Open a Connection using POST method, as it is required to use POST method. 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $encodedData); 
$encodedResponse = curl_exec($ch); 
curl_close($ch); 


//Decode response data using json_decode method to get an object. 

echo $encodedResponse; 

$response = json_decode($encodedResponse); 

echo $response;

很多擺弄我能弄清楚之後。我相信最大的錯誤是我如何設置HTTP正文。最終的代碼如下，希望這可以幫助別人！

的Objective-C：

NSString *completeString = @"http://www.mysite.com/verify.php"; 

NSURL *urlForValidation = [NSURL URLWithString:completeString]; 

NSMutableURLRequest *validationRequest = [[NSMutableURLRequest alloc] initWithURL:urlForValidation]; 

[validationRequest setHTTPMethod:@"POST"]; 

NSString *strTest = [NSString stringWithFormat:@"receipt=%@", [self base64forData:transaction.transactionReceipt]]; 

[validationRequest setHTTPBody:[strTest dataUsingEncoding:NSUTF8StringEncoding]]; 

NSData *responseData = [NSURLConnection sendSynchronousRequest:validationRequest returningResponse:nil error:nil]; 

NSString *response = [[NSString alloc] initWithData: responseData encoding: NSUTF8StringEncoding]; 

NSLog(@"%@", response); 

PHP：

$url = 'https://sandbox.itunes.apple.com/verifyReceipt'; 

$encodedData = json_encode(Array( 
    'receipt-data' => $_POST["receipt"] 
)); 


//Open a Connection using POST method, as it is required to use POST method. 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $encodedData); 
$encodedResponse = curl_exec($ch); 
curl_close($ch); 

$response = json_decode($encodedResponse); 

/* 
echo "Status Code:"; 

echo $response->{'status'}; 
*/ 

if ($response->{'status'} != 0) { 
    echo "FAIL"; 
} else { 
    echo "SUCCESS"; 
}

nlutterman的答案是正確的！它對我非常有幫助。 如果有人試圖讓他的解決方案工作，它只會在您使用以下方法將收據數據編碼爲base64（應用內）時起作用。

- (NSString*)base64forData:(NSData*)theData { 
const uint8_t* input = (const uint8_t*)[theData bytes]; 
NSInteger length = [theData length]; 

static char table[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz/="; 

NSMutableData* data = [NSMutableData dataWithLength:((length + 2)/3) * 4]; 
uint8_t* output = (uint8_t*)data.mutableBytes; 

NSInteger i; 
for (i=0; i < length; i += 3) { 
    NSInteger value = 0; 
    NSInteger j; 
    for (j = i; j < (i + 3); j++) { 
     value <<= 8; 

     if (j < length) { 
      value |= (0xFF & input[j]); 
     } 
    } 

    NSInteger theIndex = (i/3) * 4; 
    output[theIndex + 0] =     table[(value >> 18) & 0x3F]; 
    output[theIndex + 1] =     table[(value >> 12) & 0x3F]; 
    output[theIndex + 2] = (i + 1) < length ? table[(value >> 6) & 0x3F] : '='; 
    output[theIndex + 3] = (i + 2) < length ? table[(value >> 0) & 0x3F] : '='; 
} 

return [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding]; } 

正常base64EncodedStringWithOptions:是行不通的。
