Question

在我的iOS应用中，我需要检查用户的PayPal电子邮件地址是否有效。实现这个的最简单方法是什么？我一直在寻找使用GetVerifiedStatus api并尝试以下代码：

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];
    }

}

但它无法正常工作，我收到以下回复：

Paypal已验证：{ 错误=（ { category =申请; domain = PLATFORM; errorId = 580023; message =＆＃34;无法确定PayPal帐户状态＆＃34 ;; severity =错误; subdomain =应用; } ）; responseEnvelope = { ack =失败; build = 21336090; correlationId = 96eea5ecc47fb; timestamp =＆＃34; 2016-04-26T13：41：52.437-07：00＆＃34 ;; };

所以有人知道为什么我会得到＆＃34;无法确定PayPal帐户状态＆＃34;这是验证PayPal电子邮件地址的最佳方法吗？

根据错误消息，您的API请求中的电子邮件地址不是现有的PayPal沙盒帐户，因此PayPal会抛出“无法确定PayPal帐户状态”错误消息。您可以在developer.paypal.com上注册沙盒帐户，参考https://developer.paypal.com/docs/integration/paypal-here/sandbox-testing/managing-sandbox-accounts/?mark=sandbox，然后将此新沙箱帐户放入您的API请求中，试一试。

检查PayPal帐户是否存在使用电子邮件地址？
