【问题描述】:
我正在尝试对返回 JSON 的 API 运行 GET 请求。 JSON 响应如下所示:
{
"nodes": [
{
"id": "5C73B00598",
"connectionState": "connected",
"model": "PP152X"
},
{
"id": "5C73B0059E",
"connectionState": "connected",
"model": "PP152X"
},
{
"id": "4C72D012D8",
"connectionState": "connected",
"model": "PP203X"
},
{
"id": "5C73B005DE",
"connectionState": "connected",
"model": "PP152X"
},
{
"id": "5C73B005A2",
"connectionState": "connected",
"model": "PP152X"
},
{
"id": "5C73B004A2",
"connectionState": "disconnected",
"model": "PP152X"
},
{
"id": "5C73B0058B",
"connectionState": "connected",
"model": "PP152X"
}
]
}
到目前为止,仅从一个 API 文件夹返回一个响应的脚本的简化版本如下:
import requests
import json
url = "https://myurl.io/api/Customers/xxx/locations/xxx/nodes"
payload = {}
headers = {
'Content-Type': 'application/x-www-form-urlencoded',
'Authorization': 'xxx'
}
response = requests.request("GET", url, headers=headers, data = payload)
str = response.text.strip()
json_str = json.loads(str)
print(len(json_str['nodes']))
i = 0
while i <= len(json_str['nodes']):
#cus_list = json_str['nodes'][i]['connectionState']
#cus_lists.append(cus_list)
print(json_str['nodes'][i]['connectionState'])
i += 1
当我运行这个脚本时,while 循环不会返回 'connectionState' 的 7 次迭代,而只是返回第一次。
【问题讨论】:
-
不回答您的问题,但您的 while 循环中的条件应使用
<。还要粘贴该打印语句的实际输出和响应,而不是输出的截断版本。 -
抛开条件,循环似乎很好。您确定它从 api 响应返回 7 而不是 1?
