Answer 1

把你的ss里的json拿出来单独看。

"data":[{"amount":"400","financeAmount":"400万","financeAmountUnit":"CNY","financeDate":1514649600000,"newsUrl":"http://www.lieyunwang.com/archives/447914","participantVos":[{"entityId":117,"entityName":"联想之星","entityType":2,"investmentId":181676}],"phase":"ANGEL"}]

很明显的这根本不是个完整的json。
把前面的"data":去掉再试一下感觉一下。

Answer 2

s前加{,后加}

Answer 3

http://www.bejson.com/ 推荐个工具，以后看看是不是个json再去转义，很明显你的那个字符串就不是个json。

Answer 4

import json

ss = """{"data":[{"amount":"400","financeAmount":"400万","financeAmountUnit":"CNY","financeDate":1514649600000,"newsUrl":"http://www.lieyunwang.com/archives/447914","participantVos":[{"entityId":117,"entityName":"联想之星","entityType":2,"investmentId":181676}],"phase":"ANGEL"}]}"""

print(json.loads(ss))

输出如下

{'data': [{'amount': '400',
'financeAmount': '400万',
'financeAmountUnit': 'CNY',
'financeDate': 1514649600000,
'newsUrl': 'http://www.lieyunwang.com/arc...',
'participantVos': [{'entityId': 117,

 'entityName': '联想之星',
 'entityType': 2,
 'investmentId': 181676}],
'phase': 'ANGEL'}]}

错误原因，数据没有使用以{}开始，结束，json数据必须放在{}里面
