this is the python code
Code: [Select]
    def request(self, method, *args):
        payload = {
            "method": method,
            "params": list(*args),
            "jsonrpc": "2.0",
            "id": 0,
        }
        headers = {
          'content-type': 'application/json',
          'Authorization': "Basic YTph"
        }
        response = requests.post(self.url, data=json.dumps(payload), headers=headers)
        return response
here is the output for print(list(*args)),and the type for price is double

The feed scripts use float() with %g to format the number .. maybe thats the issue ...

I think xeroc is correct, it looks like the exponent at the end of "1.2028997179833209e-05" might be causing the failure.

I don't know where it convert price  from type float to type string
from the output above, it's still float when I call requests.post()

Anyway encoded HTTP post data is a String. You have this in the data:
Code: [Select]
['ask_order', ['fund.btsbots', 11429.350384438114, 'BTS', 1.202899717
9833209e-05, 'GOLD']]

thank you,json.dumps  convert float to scientific notation,
I don't know how to change that,
so I have to replace scientific notation to fixed point with string replace.
here is the code to replace scientific notation to fixed point
Code: [Select]
import re
def to_fixed_point(match):
    """Return the fixed point form of the matched number.

    Parameters:
        match is a MatchObject that matches exp_regex or similar.

    If you wish to make match using your own regex, keep the following in mind:
        group 1 should be the coefficient
        group 3 should be the sign
        group 4 should be the exponent

    """
    sign = -1 if match.group(3) == "-" else 1
    coefficient = float(match.group(1))
    exponent = sign * float(match.group(4))
    return "%.16f" % (coefficient * 10**exponent)

class BTS():
.....
        exp_regex = re.compile(r"(\d+(\.\d+)?)[Ee](\+|-)(\d+)")
        response = requests.post(self.url, data=exp_regex.sub(to_fixed_point,json.dumps(payload)), headers=headers)
......
