调用数据时会出现JSONDecodeError

[Chaoji112]

【第一次编辑Issue，格式不对还请谅解】 版本：Spyder 3.3.6 + python 3.7 问题：在通过端口调取数据时会出现JSONDecodeError （目前使用过daily和balancesheet），重新运行代码有时可以解决，有时不行。

出错情况： while j<count: temp = pd.DataFrame() code = tushare_data.loc[j, 'ts_code'] start = tushare_data.loc[j, 'issue_date'] end = "{}1231".format(pd.to_datetime(start).year)
print('Getting company data for {}'.format(tushare_data.loc[j, 'ts_code'])) temp = pro.balancesheet(ts_code=code,start_date=start,end_date=end) company_data = company_data.append(temp,ignore_index=True) j=j+1

Error Output: Traceback (most recent call last): File "", line 7, in temp = pro.balancesheet(ts_code=code,start_date=start,end_date=end) File "D:\Anaconda\lib\site-packages\tushare\pro\client.py", line 41, in query result = json.loads(res.text) File "D:\Anaconda\lib\json__init__.py", line 348, in loads return _default_decoder.decode(s) File "D:\Anaconda\lib\json\decoder.py", line 337, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "D:\Anaconda\lib\json\decoder.py", line 355, in raw_decode raise JSONDecodeError("Expecting value", s, err.value) from None JSONDecodeError: Expecting value

还是python新手，不确定是哪方面的问题。

Similar to issue #1232

check your network. or switch to another network.

This is caused by network, looks the network disallowed the connection to tushare server. After switching to another network, the issue no longer exist.
