Question

python3通过pycharm编译器调用requests接口返回JSON格式Unexpected UTF-8 BOM (decode using utf-8-sig)

代码如下：
class http:
def __init__(self,url,data):
self.url = url
self.data = data

def httpPost(self):
req = requests.post(self.url,self.data)
return req.json()

访问时报错信息：
Traceback (most recent call last):
File "C:/Python34/YunYingPingTai/Channel/HttpRequest.py", line 26, in <module>
print(t.json())
File "C:\Python34\lib\site-packages\requests\models.py", line 892, in json
return complexjson.loads(self.text, **kwargs)
File "C:\Python34\lib\json\__init__.py", line 314, in loads
raise ValueError("Unexpected UTF-8 BOM (decode using utf-8-sig)")
ValueError: Unexpected UTF-8 BOM (decode using utf-8-sig)

大佬们求帮帮忙啊啊啊啊啊啊啊

因为你的req内容包含BOM字符，去掉req中BOM头的方法如下

if req.startswith(u'\ufeff'):
    req = req.encode('utf8')[3:].decode('utf8')

追问

我想请问下，我把去除BOM的这个代码，加在哪里呢；我比较菜，我之前百度到的方法大概也是这么讲的，只是不清楚加在哪里，然后怎么把去除BOM后的JSON打印出来，帮帮我。谢谢！
