【问题描述】：

我正在尝试使用 .NET SDK 在 PayPal 中创建新协议，但是当我将我的协议连同我的计划和协议详细信息发送到 PayPal API 时，我收到了 400 Bad Request 错误。经过进一步调查，我发现这是由于Plan Id 无效，但我不知道为什么会这样，因为我已经在模型、BillingPlansController 和 PayPal 仪表板中创建了它。

这是来自 PayPal API 的响应 Json：

   "name":"TEMPLATE_ID_INVALID",
   "debug_id":"9e24570510a3e",
   "message":"",
   "information_link":"https://developer.paypal.com/docs/api/payments.billing-agreements#errors",
   "details":[
      
         "field":"validation_error",
         "issue":"Incorrect Plan Id."
      
   ]

这是我的Plan 模型，我在其中创建了要在我的应用程序中使用的计划。

public class Plan

   public string PayPalPlanId  get; set; 
   public string Name  get; set; 
   public decimal Price  get; set; 
   public int NumberOfEmployees  get; set; 
   public string Description  get; set; 
   public static List<Plan> Plans => new List<Plan>()
   
      new Plan()
      
          Name = "Starter Subscription",
          Price = 30,
          PayPalPlanId = "P-27H34871BG666983A2CPYWUI",
          NumberOfEmployees = 1,
          Description = "Access to the website for a monthly payment"
      
   ;

这是我SubscriptonController的相关部分

public ActionResult Purchase(PurchaseVm model)

   var plan = Plan.Plans.FirstOrDefault(x => x.PayPalPlanId == model.Plan.PayPalPlanId);
   if (ModelState.IsValid)
   
        var startDate = DateTime.UtcNow.AddMonths(1);
        var apiContext = GetApiContext();

        var subscription = new Subscription()
        
             FirstName = model.FirstName,
             LastName = model.LastName,
             Email = model.Email,
             StartDate = startDate,
             NumberOfEmployees = plan.NumberOfEmployees,
             PayPalPlanId = plan.PayPalPlanId
        ;
        _dbContext.Subscriptions.Add(subscription);
        _dbContext.SaveChanges();

        var agreement = new Agreement()
        
             name = plan.Name,
             description = $"blah blah blah",
             start_date = startDate.ToString("yyyy-MM-ddTHH:mm:ssZ"),
             create_time = DateTime.Now.ToString("yyyy-MM-ddTHH:mm:ssZ"),
             plan = new PayPal.Api.Plan()
             
                id = plan.PayPalPlanId,
             ,
             payer = new Payer()
             
                payment_method = "paypal",
                payer_info = new PayerInfo()
                
                   first_name = model.FirstName,
                   last_name = model.LastName, 
                   email = model.Email
                
             
        ;
        // the line below is where the error occurs
        var createdAgreement = agreement.Create(apiContext);
        subscription.PayPalAgreementToken = createdAgreement.token;
        _dbContext.SaveChanges();

       var approvalUrl = createdAgreement.links.FirstOrDefault(x => x.rel.Equals("approval_url",
           StringComparison.OrdinalIgnoreCase));
       return Redirect(approvalUrl.href);
    
    model.Plan = plan;
    return View(model);

请注意，在上面的代码中，我的控制器中有一个 GetAPIContext() 方法。

这是发送到 PayPal API 的数据

   "name":"Starter Subscription",
   "description":"Access to the website for a monthly payment",
   "start_date":"2020-07-15T12:44:06Z",
   "payer":
      "payment_method":"paypal",
      "payer_info":
         "email":"xxxx",
         "first_name":"xxx",
         "last_name":"xxx"
      
   ,
   "plan":
      "id":"P-4PV26268V7918953BL3S3ZHA"

看起来 PayPal 已弃用我正在使用的 API 版本。
