蟒蛇功能，json.loads（）：無JSON對象可以解碼

Question

的代碼非常簡單：

import requests 
import json 

r = requests.get('https://www.baidu.com/') 
r.encoding = 'utf-8' 
json.loads(r.text,'utf-8') 

我總是收到此錯誤信息：

Traceback (most recent call last): 
File "<pyshell#57>", line 1, in <module> 
json.loads(r.text,'utf-8') 
File "C:\Python27\lib\json\__init__.py", line 352, in loads 
return cls(encoding=encoding, **kw).decode(s) 
File "C:\Python27\lib\json\decoder.py", line 364, in decode 
obj, end = self.raw_decode(s, idx=_w(s, 0).end()) 
File "C:\Python27\lib\json\decoder.py", line 382, in raw_decode 
raise ValueError("No JSON object could be decoded") 
ValueError: No JSON object could be decoded 

誰能幫助我解決這個問題？謝謝！

此代碼將幫助你弄清楚是怎麼回事;）

import requests 
import json 

r = requests.get('https://www.baidu.com/') 
r.encoding = 'utf-8' 

try: 
    foo = json.loads(r.text, 'utf-8') 
    print "Yay, I got a json from baidu!" 
except Exception, e: 
    print "Why didn't i get a json from baidu? Maybe it wasn't a json..." 
    print "What is it then? It seems is a {0} whose length is {1}".format(
     r.text.__class__, len(r.text) 
    )
