尝试在使用 Paypal 沙箱的 grails 项目中通过集成测试来测试 Paypal 付款。在这个阶段，我正在尝试使用 REST API 创建一个 Paypal 付款。

代码片段：

def jsonPaypalPayment ='''
{
  "intent": "sale",
  "redirect_urls": [{
    "return_url": "http://<return URL here>",
    "cancel_url": "http://<cancel URL here>"
  }],
  "payer": {
    "payment_method": "paypal"
  },
  "transactions": [{
    "amount": {
      "total": "0.10",
      "currency": "USD",
    },
    "description": "This is the payment transaction description."
  }]
}
'''

def client = new RESTClient("https://api.sandbox.paypal.com")
client.contentType = ContentType.JSON
client.headers.'Authorization' = "${tokenType} ${accessToken}"
def resp = client.post(path: "/v1/payments/payment", body: jsonPaypalPayment)

tokenType 和 accessToken 在上一步中成功检索。

post 方法返回“400 Bad Request”响应。从文档中获取了带有非常小的 mods 的示例请求。

完整的调试输出：

我注意到 REST API 处于测试阶段。文件是否准确？端点是否经过测试？REST API 计划何时发布？关于错误请求的任何见解？提前致谢。

您传递的 JSON 无效（格式错误），因为在currency值之后似乎有一个额外的逗号。

这是一个直接来自文档的有效示例：

{
   "intent":"sale",
   "redirect_urls":{
      "return_url":"http://<return URL here>",
      "cancel_url":"http://<cancel URL here>"
   },
   "payer":{
      "payment_method":"paypal"
   },
   "transactions":[
      {
         "amount":{
            "total":"7.47",
            "currency":"USD"
         },
         "description":"This is the payment transaction description."
      }
   ]
}
