貝寶REST API錯誤請求

Question

嘗試通過集成測試在使用Paypal沙箱的Grails項目中測試Paypal付款。在這個階段，我正嘗試使用REST API創建Paypal付款。

代碼片斷：

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和的accessToken在先前步驟中成功地檢索。

post方法返回「400錯誤請求」響應。從非常小的mods的文檔採取樣本請求。

全部調試輸出：

我已經注意到，REST API是測試版。文檔是否準確？端點是否已經過測試？ REST API計劃何時發佈？關於不良要求的任何見解？提前致謝。

Answer 1

您傳遞的JSON無效（格式錯誤），因爲它看起來在currency值後面有一個額外的逗號。

這裏是直接從文檔的有效例如：

{ 
    "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." 
     } 
    ] 
}
