为凭证 IOS SDK 2.1.6 设置 Paypal 客户端 ID

Question

我在我的应用中使用 Paypal SDK。我将我的环境设置为 PayPalEnvironmentSandbox，但是当我运行我的应用程序时，会出现一条警报，提示“与 Paypal 服务器通信时出现问题。请重试”。我用谷歌搜索了很多次，其他人说我需要更改客户端 ID，但我不知道如何更改客户端 ID，我在 paypal 的沙盒上有一个测试帐户，但我不知道如何在我的应用程序中实现它们。我阅读了文档，他们说我需要更改可能的客户 ID，但我不知道如何。需要你们的帮助，谢谢。我正在使用 iOS paypal SDK 2.1.6。

代码：

#import "ZZMainViewController.h"
#import <QuartzCore/QuartzCore.h>
#import "PayPalMobile.h"

// Set the environment:
// - For live charges, use PayPalEnvironmentProduction (default).
// - To use the PayPal sandbox, use PayPalEnvironmentSandbox.
// - For testing, use PayPalEnvironmentNoNetwork.
//#define kPayPalEnvironment PayPalEnvironmentNoNetwork
#define kPayPalEnvironment PayPalEnvironmentSandbox

@interface ZZMainViewController ()

@property(nonatomic, strong, readwrite) IBOutlet UIButton *payNowButton;
@property(nonatomic, strong, readwrite) IBOutlet UIButton *payFutureButton;
@property(nonatomic, strong, readwrite) IBOutlet UIView *successView;

@property(nonatomic, strong, readwrite) PayPalConfiguration *payPalConfig;

@end

@implementation ZZMainViewController

  _payPalConfig.merchantPrivacyPolicyURL = [NSURL URLWithString:@"https://www.paypal.com/webapps/mpp/ua/privacy-full"];
  _payPalConfig.merchantUserAgreementURL = [NSURL URLWithString:@"https://www.paypal.com/webapps/mpp/ua/useragreement-full"];


  // Setting the languageOrLocale property is optional.
  //
  // If you do not set languageOrLocale, then the PayPalPaymentViewController will present
  // its user interface according to the device's current language setting.
  //
  // Setting languageOrLocale to a particular language (e.g., @"es" for Spanish) or
  // locale (e.g., @"es_MX" for Mexican Spanish) forces the PayPalPaymentViewController
  // to use that language/locale.
  //
  // For full details, including a list of available languages and locales, see PayPalPaymentViewController.h.

    _payPalConfig.languageOrLocale = [NSLocale preferredLanguages][0];


  // Do any additional setup after loading the view, typically from a nib.

Answer 1

要获得 client_id，您需要在 https://developer.paypal.com/webapps/developer/applications/myapps 注册并创建一个应用程序。然后，您将获得沙盒（和实时）凭据。

Answer 2

这里是来自 PayPal 的戴夫。

要设置您的客户端 ID（一个用于 Sandbox，一个用于 Live），请参阅我们的Sample Code 中的第 1 步：

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // ...
    [PayPalMobile initializeWithClientIdsForEnvironments:@{PayPalEnvironmentProduction : @"YOUR_CLIENT_ID_FOR_PRODUCTION",
                                                     PayPalEnvironmentSandbox : @"YOUR_CLIENT_ID_FOR_SANDBOX"}];
  // ...
    return YES;
}

Answer 3

您必须在 appdelegate.m 文件中进行更改。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary      *)launchOptions { #warning "Enter your credentials"
  [PayPalMobile initializeWithClientIdsForEnvironments:@{PayPalEnvironmentProduction :    @"YOUR_CLIENT_ID_FOR_PRODUCTION",
  PayPalEnvironmentSandbox : @"ATIXyxAAjtL8-HdqfLq0kTCeefUi1SNI_xkfWktHelloqznRxsrm_Hello"}]; return YES;}

Answer 4

用于 Swift 开发

    [PayPalMobile initializeWithClientIdsForEnvironments:@{PayPalEnvironmentProduction                             :@"YOUR_CLIENT_ID_FOR_PRODUCTION",
      PayPalEnvironmentSandbox : @"ATIXyxAAjtL8-HdqfLq0kTCeefUi1SNI_xkfWktHelloqznRxsrm_Hello"}];

你需要做的不会工作

 PayPalMobile.initializeWithClientIdsForEnvironments([PayPalEnvironmentProduction: "ID1", PayPalEnvironmentSandbox: "ID2"])
