(以下为Python示例)
- 要求身份验证
为了使用物流API,您需要向提供API的公司申请API密钥,并在每个API请求中使用该密钥进行身份验证。示例代码如下:
import requests
api_key = 'your_api_key'
api_url = 'https://api.logistics.com'
Make the request with the API key
response = requests.get(api_url, headers={'Authorization': api_key})
- 限制请求频率
为了避免过多的API请求对服务器造成负担,物流服务提供商可能会限制您的API请求频率。示例代码如下:
import time
import requests
api_key = 'your_api_key'
api_url = 'https://api.logistics.com'
Make the request with the API key
while True:
response = requests.get(api_url, headers={'Authorization': api_key})
if response.status_code == 429:
# Too many requests - wait for the retry-after header
time.sleep(int(response.headers['retry-after']))
else:
# Success - process the response
process_response(response.json())
- 限制返回结果数量
为了避免返回超过您的应用程序处理能力的结果,物流服务提供商可能会限制返回结果的数量。示例代码如下:
import requests
api_key = 'your_api_key'
api_url = 'https://api.logistics.com'
Limit to 10 results
response = requests.get(api_url + '?limit=10', headers={'Authorization': api_key})
Process the response
process_response(response.json())
