我想将数据添加到我的REST调用中，但这会导致有效负载中包含以下字符串（注意：方括号中的单引号：
x = df.to_json(orient='records')
print(x)
[{"val":"3760","id":"204","quantity":2},{"val":"8221","id":"220","quantity":8}]
JASON值被列为一个大字符串这一事实，REST调用导致HTTP 400错误。
代码是：
'updateVals': '[{"val":"3760","id":"204","quantity":2},{"val":"8221","id":"220","quantity":8}]'}}
如何将JSON插入REST调用中？我认为我必须拆分字符串，或者也许有一个更直接的答案？
答案 0 :(得分：0)
仍然不确定您需要什么，JSON实际上是一个大字符串：
x = [{"val":"3760","id":"204","quantity":2},
{"val":"8221","id":"220","quantity":8}]
>>> json.dumps(x)
>>> '[{"val": "3760", "id": "204", "quantity": 2}, {"val": "8221", "id": "220", "quantity": 8}]'
