条带API通过iOS代码创建费用？

我一直在使用stripe开发ApplePay，一切正常，直到使用PKPayment获取stripe令牌这里提到的每个人都将您的stripe令牌发送到服务器并收取金额。我不知道如何创建web服务和向服务器发送令牌。所以我计划通过iOS代码给卡充电

创建费用单据：

在这里，我们不知道如何使用密钥生成post数据

NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:config];

    NSString *urlString = @"https://api.stripe.com/v1/charges";
    NSURL *url = [NSURL URLWithString:urlString];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
    request.HTTPMethod = @"POST";
    NSString *postBody = [NSString stringWithFormat:@"source=%@&amount=%@", sourceID, @1099];
    NSData *data = [postBody dataUsingEncoding:NSUTF8StringEncoding];

    NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:request
                                                               fromData:data
                                                      completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
                                                          NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
                                                          if (!error && httpResponse.statusCode != 200) {
                                                              error = [NSError errorWithDomain:StripeDomain
                                                                                          code:STPInvalidRequestError
                                                                                      userInfo:@{NSLocalizedDescriptionKey: @"There was an error connecting to your payment backend."}];
                                                          }
                                                          if (error) {
                                                              completion(STPBackendChargeResultFailure, error);
                                                          } else {
                                                              completion(STPBackendChargeResultSuccess, nil);
                                                          }
                                                      }];

    [uploadTask resume];

错误：

You did not provide an API key. You need to provide your API key in the Authorization header, using Bearer auth (e.g. 'Authorization: Bearer YOUR_SECRET_KEY'). See https://stripe.com/docs/api#authentication for details, or we can help at https://support.stripe.com/.

我们看到了类似的问题

提前感谢。

您不应该在iOS应用程序中创建费用。您需要您的密钥来创建费用，从应用程序中存储您的api密钥或在应用程序中检索您的密钥都是不安全的

您的公钥可以安全地存储在应用程序中以创建令牌，然后您可以将该令牌发送到后端以创建费用。这允许您的密钥安全地存储在服务器上

下面是Stripe的ruby后端示例，它向您展示了如何使用您创建的令牌创建费用：
