使用墨迹天气的api查询天气出现401: Unauthorized

小白桦

使用了墨迹天气的api想要查询天气，里面给出了请求实例使用python2写的如下：

1. import urllib, urllib2, sys
   
2. 
   
3. 
   
4. host = 'http://freecityid.market.alicloudapi.com'
   
5. path = '/whapi/json/alicityweather/briefforecast3days'
   
6. method = 'POST'
   
7. appcode = '你自己的AppCode'
   
8. querys = ''
   
9. bodys = {}
   
10. url = host + path
    
11. 
    
12. bodys['cityId'] = '''2'''
    
13. bodys['token'] = '''677282c2f1b3d718152c4e25ed434bc4'''
    
14. post_data = urllib.urlencode(bodys)
    
15. request = urllib2.Request(url, post_data)
    
16. request.add_header('Authorization', 'APPCODE ' + appcode)
    
17. //根据API的要求，定义相对应的Content-Type
    
18. request.add_header('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8')
    
19. response = urllib2.urlopen(request)
    
20. content = response.read()
    
21. if (content):
    
22.     print(content)

复制代码

我把他改成python3的代码如下：

1. import urllib.parse
   
2. import urllib.request
   
3. 
   
4. host = 'http://freecityid.market.alicloudapi.com'
   
5. path = '/whapi/json/alicityweather/briefforecast3days'
   
6. method = 'POST'
   
7. appcode = '708efccf6eb5445fae08702f68c5695c'
   
8. querys = ''
   
9. bodys = {}
   
10. url = host+path
    
11. bodys['cityId'] = '2'
    
12. bodys['token'] = ''
    
13. post_data = urllib.parse.urlencode(bodys).encode('utf-8')
    
14. request = urllib.request.Request(url, post_data)
    
15. request.add_header('Authorization', 'APPCODE' + appcode)
    
16. request.add_header('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8')
    
17. response = urllib.request.urlopen(request)
    
18. content = response.read()
    
19. if content:
    
20.     print(content)

复制代码

出现了以下错误：

1. Traceback (most recent call last):
   
2.   File "D:/Python/weather/tq.py", line 20, in <module>
   
3.     response = urllib.request.urlopen(request)
   
4.   File "D:\Python\lib\urllib\request.py", line 222, in urlopen
   
5.     return opener.open(url, data, timeout)
   
6.   File "D:\Python\lib\urllib\request.py", line 531, in open
   
7.     response = meth(req, response)
   
8.   File "D:\Python\lib\urllib\request.py", line 641, in http_response
   
9.     'http', request, response, code, msg, hdrs)
   
10.   File "D:\Python\lib\urllib\request.py", line 569, in error
    
11.     return self._call_chain(*args)
    
12.   File "D:\Python\lib\urllib\request.py", line 503, in _call_chain
    
13.     result = func(*args)
    
14.   File "D:\Python\lib\urllib\request.py", line 649, in http_error_default
    
15.     raise HTTPError(req.full_url, code, msg, hdrs, fp)
    
16. urllib.error.HTTPError: HTTP Error 401: Unauthorized

补充一下，因为token参数介绍里面写的是可选我就没写

小白桦

自己顶一下

ABC23

把header加上改成User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36

再看看要不要账号密码登陆，如果需要就把它写到你的程序中。
可以试试cookie登陆

小白桦

将token参数加上，第十五行改为如下：

1. request.add_header('Authorization', 'APPCODE'+' ' + appcode)
