URL的主机值将作为参数传递,但是当我打印URL时,它可以正常工作,但不能作为整个脚本正常执行。
Python脚本:
import requests
import json
import urllib
import sys
import os
host=(str(sys.argv[1]))
headers={
"accept": "application/json",
"content-type": "application/json"
}
test_urls = 'https://{host}/Thingworx/Things/PG.MonitorStats.Stream/Services/GetStreamData?maxItems=1&oldesFirst=false&appKey=0b858f3f-4ed0-499c-a4d2-9ad0fbc0da9b&method=post'.format(host=host)
print (test_urls)
def return_json(url):
try:
response = requests.get(url,headers=headers)
# Consider any status other than 2xx an error
if not response.status_code // 100 == 2:
return "Error: Unexpected response {}".format(response)
json_obj = response.json()
return json.dumps(json_obj)
except requests.exceptions.RequestException as e:
# A serious problem happened, like an SSLError or InvalidURL
return "Error: {}".format(e)
for url in test_urls:
print return_json(url).format(host=host)
错误输出:
Error: Invalid URL 'h': No schema supplied. Perhaps you meant http://h?
Error: No connection adapters were found for ':'
Error: Invalid URL '/': No schema supplied. Perhaps you meant http:///?
[test_urls
是一个字符串(不是字符串数组),因此您要遍历每个字符并尝试先获取h
,然后依次为t
,然后依次为t
,...
并且format
的输出上的return_json
没有意义。您的print
也没有(假设您使用的是Python 3,则print是一个函数)。
也请求具有用于“将2xx以外的其他状态视为错误”的快捷方式:Response.ok
和Response.ok
。
而且...为什么要转储JSON响应?如果需要文本版本,只需返回Response.raise_for_status()
,就没有理由解码,然后立即重新编码响应。
