ios - 无法使用 "v1/vault/credit-cards"在 Paypal 中存储信用卡

Question

我正在为我的一个应用程序使用 Paypal 保险库。我需要将信用卡存储到保险库中。我为此使用了 paypal vault api (v1/vault/credit-cards)。但它总是返回 500。我也尝试使用实际的信用卡，但没有得到积极的回应。我能够获得访问 token 并在列表服务中获得成功响应。但是不能存卡。下面是我的代码:

请求参数:

   NSMutableDictionary *dicCC = [[NSMutableDictionary alloc]init];
            dicCC[@"payer_id"] = @"123345";
            dicCC[@"type"] = @"visa";
            dicCC[@"number"] = @"4427802641004797";
            dicCC[@"expire_month"] = [NSNumber numberWithInt:11];
            dicCC[@"expire_year"] = [NSNumber numberWithInt:2018];
            dicCC[@"first_name"] = @"Jack";
            dicCC[@"last_name"] = @"Sparrow";
            dicCC[@"cvv2"] = @"124";

            NSString *strWebService = [NSString stringWithFormat:@"https://api.sandbox.paypal.com/v1/vault/credit-cards"];
            AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

            // For HTTPBody with custom String format
            [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
            [manager.requestSerializer setValue:strAccessToken forHTTPHeaderField:@"Authorization"];

            [manager POST:strWebService parameters:dicCC progress:^(NSProgress * _Nonnull uploadProgress) {

            } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
                NSLog(@"%@",responseObject);
            } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
                NSLog(@"%@",error.description);
            }];

响应:

谁能帮我解决这个问题？

谢谢，

            override fun onResponse(call: Call<AuthenticationCardModel>?, response: retrofit2.Response<AuthenticationCardModel>?) {
                if (response != null) {
