檢查PayPal帳戶是否存在使用電子郵件地址？

在我的iOS應用程序中，我需要檢查用戶的PayPal電子郵件地址是否有效。實現這個最簡單的方法是什麼？我一直都在使用GetVerifiedStatus API和嘗試下面的代碼：檢查PayPal帳戶是否存在使用電子郵件地址？

NSDictionary *dict1 = [[NSDictionary alloc]initWithObjectsAndKeys:email, @"emailAddress", nil]; 

NSDictionary *postDict = [[NSDictionary alloc]initWithObjectsAndKeys: dict1,@"accountIdentifier",@"NONE",@"matchCriteria", 
          [[NSDictionary alloc] initWithObjectsAndKeys:@"en_US", @"errorLanguage", @"detailLevel", @"ReturnAll", nil], @"requestEnvelope", nil]; 

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"https://svcs.sandbox.paypal.com/AdaptiveAccounts/GetVerifiedStatus"]] cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:60.0]; 

[request setHTTPMethod:@"POST"]; 
[request addValue:@"your_user_id" forHTTPHeaderField:@"X-PAYPAL-SECURITY-USERID"]; 
[request addValue:@"your_password" forHTTPHeaderField:@"X-PAYPAL-SECURITY-PASSWORD"]; 
[request addValue:@"your_signature" forHTTPHeaderField:@"X-PAYPAL-SECURITY-SIGNATURE"]; 
[request addValue:@"APP-80W284485P519543T" forHTTPHeaderField:@"X-PAYPAL-APPLICATION-ID"]; 
[request addValue:@"JSON" forHTTPHeaderField:@"X-PAYPAL-REQUEST-DATA-FORMAT"]; 
[request addValue:@"JSON" forHTTPHeaderField:@"X-PAYPAL-RESPONSE-DATA-FORMAT"]; 
[request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 
[request addValue:@"en_US" forHTTPHeaderField:@"Accept-Language"]; 

NSError *dError = nil; 
NSData *postData = [NSJSONSerialization dataWithJSONObject:postDict options:0 error:&dError]; 

[request setHTTPBody:postData]; 

NSError *error = nil; 
NSHTTPURLResponse *res = nil; 

NSData *retData = [NSURLConnection sendSynchronousRequest:request returningResponse:&res error:&error]; 

if (error) 
{ 
    NSLog(@"Error getting paypal verification: %@", error); 
} 
else 
{ 

    NSError *jsonError = nil; 
    NSDictionary *details = [NSJSONSerialization JSONObjectWithData:retData options:kNilOptions error:&jsonError]; 

    if (jsonError != nil) { 

     NSLog(@"Error parsing JSON %@", jsonError); 
    } 
    else { 

     NSLog(@"Paypal Verified: %@", details); 

     [self savePayPal]; 
    } 

}

但它不能正常工作，我得到如下回應：

淘寶鑽石賣家：{ 誤差=（ { category = Application; domain = PLATFORM; errorId = 580023; message =「無法確定PayPal帳戶狀態」; severity =錯誤; subdomain = Appl ication; } ）; responseEnvelope = { ack =失敗; build = 21336090; correlationId = 96eea5ecc47fb; timestamp =「2016-04-26T13：41：52.437-07：00」; };

因此，沒有人知道我爲什麼會收到「無法確定PayPal賬戶狀態」，這是驗證PayPal電子郵件地址的最佳方法嗎？

根據錯誤消息，您的API請求中的電子郵件地址不是已有的PayPal沙箱帳戶，因此PayPal會拋出「無法確定PayPal帳戶狀態」錯誤消息。您可以在developer.paypal.com上註冊一個沙盒帳戶，請參閱https://developer.paypal.com/docs/integration/paypal-here/sandbox-testing/managing-sandbox-accounts/?mark=sandbox，然後將這個新的沙盒帳戶放入您的API請求中，試試看。
