在 Python 中使用 API-请求？

Question

我想使用来自此页面的 api-请求：

https://www.jamesallen.com/loose-diamonds/all-diamonds/page-4/?Color=Y,J,I,H,G,F,E,D&Cut=Good,Very+Good,Ideal,TrueHearts&Shape=all-diamonds&Clarity=I1,SI2,SI1,VS2,VS1,VVS2,VVS1,IF,FL&CaratFrom=0.05&IsLabDiamond=True

我想我找到了请求-url:

https://product-service.r2net.com/diamond/v/2/

在有效负载选项卡中，我还认为我找到了所有使用的参数。

所以我用下面的代码试了一下 -

但不幸的是，我在 vscode 中收到一个错误，即有效负载分配不正确（第一个 { 下划线来自 payload =）

如何在 python 中使用这个 api？

Answer 1

如前所述，您的有效负载变量无效 json。它还需要 "query" 键。

试一试：

import requests

headers =   {
      'appid':'jamesallen',
      'user-agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36'
      }
payload = {"query":"""{
        searchByIDs(price:{from:200, to:5000000} 
        carat:{from:0.05, to:30} 
        page:{count:5, size:23, number:6}depth:{from:46, to:78}tableSize:{from:52, to:80}color:{from: 1 to: 24} cut:{from: 0 to: 4} clarity:{from: 1 to: 9} isLabDiamond:true shippingDays:999 ) {    
          total
          hits
          pageNumber

              }
          }
        }"""}

url = "https://product-service.r2net.com/diamond/v/2/"

resp = requests.post(url,json=payload, headers=headers).json()
print(resp)

输出：
