我尝试查看所有其他问题，但似乎没有任何问题可以解决此问题。我已经缩小范围，所以来自https://sandbox.itunes.apple.com/verifyReceipt的响应很简单{"status":21002}。任何帮助将不胜感激，我已经复制了下面的相关代码。

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[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=";

    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];
}

最后这是使用的 PHP 代码：

$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;

经过大量的摆弄，我能够弄清楚。我相信最大的错误在于我如何设置 HTTP 正文。最终代码如下，希望这可以帮助其他人！

目标-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 的回答是正确的！它对我帮助很大。如果有人试图让他的解决方案发挥作用，那么只有使用以下方法将收据数据编码为 base64（应用内），它才会起作用。

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

static char table[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=";

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]; }

正常的base64EncodedStringWithOptions:就不行了。
