关于FTX美国API POST请求的问题

Question

我查看了在这里找到的FTX文档：https://docs.ftx.us/#overview

我看过这个回购程序中的示例代码：https://github.com/ftexchange/ftx/tree/master/rest

我在/wallet/withdrawals上点击POST请求，但我得到了

{“成功”：假，“错误”：“未登录:无效签名”，"errorCode":"not_logged_in"}

这是我的密码：

        resp = requests.get('https://otc.ftx.com/api/time')
        ftx_t = resp.json()
        time = ftx_t['result']
        date_format = datetime.datetime.strptime(time, "%Y-%m-%dT%H:%M:%S.%f%z")
        unix_time = datetime.datetime.timestamp(date_format)
        ts = unix_time * 1000
        # ts = int(time.time() * 1000)
        request = Request('**POST**', '**https://ftx.us/api/wallet/withdrawals**')  # To make withdrawas
        prepared1 = request.prepare()
        body = {
            "coin": "USDT",   # coin to withdraw
            "size": 0,  # amount to withdraw
            "address": "***************"  # address to send to
        }
        signature_payload1 = f'{ts}{prepared1.method}{prepared1.path_url}'.encode()
        signature1 = hmac.new('**SECRET KEY**'.encode(), signature_payload1, 'sha256').hexdigest()

        prepared1.headers[f'FTXUS-KEY'] = '**API KEY**'
        prepared1.headers[f'FTXUS-SIGN'] = signature1
        prepared1.headers[f'FTXUS-TS'] = str(ts)
        prepared1.headers['Content-Type'] = 'application/json'
        prepared1.headers['Accept'] = 'application/json'
        
        data1 = json.dumps(body).encode()


        res10 = requests.post('https://ftx.us/api/wallet/withdrawals', data=data1, headers=prepared1.headers)

您需要对发送post请求的数据进行编码，并在请求POST请求时将这些编码的数据添加到正文中。

这可能有助于：

在调用signature1变量之前，需要添加以下内容：

prepared1.body = json.dumps(body).encode()
if prepared1.body:
   signature_payload1 += prepared1.body

在POST请求方法中，在数据属性中添加主体

res10 = requests.post('https://ftx.us/api/wallet/withdrawals', data=prepared1.body, headers=prepared1.headers)

在这里，我为您编辑了代码：

 resp = requests.get('https://otc.ftx.com/api/time')
            ftx_t = resp.json()
            time = ftx_t['result']
            date_format = datetime.datetime.strptime(time, "%Y-%m-%dT%H:%M:%S.%f%z")
            unix_time = datetime.datetime.timestamp(date_format)
            ts = (unix_time * 1000)
            request = Request('POST', 'https://ftx.us/api/wallet/withdrawals')  # To make withdrawas
            prepared1 = request.prepare()
            signature_payload1 = f'{ts}{prepared1.method}{prepared1.path_url}'.encode()
            body = {
                "coin": "USDT",  # coin to withdraw
                "size": 0,  # amount to withdraw
                "address": "***************"  # address to send to
            }
            prepared1.body = json.dumps(body).encode()
            if prepared1.body:
                signature_payload1 += prepared1.body
            signature1 = hmac.new(SECRET KEY.encode(), signature_payload1,
                                  'sha256').hexdigest()

            prepared1.headers[f'FTXUS-KEY'] = API KEY
            prepared1.headers[f'FTXUS-SIGN'] = signature1
            prepared1.headers[f'FTXUS-TS'] = str(ts)
            prepared1.headers['Content-Type'] = 'application/json'
            prepared1.headers['Accept'] = 'application/json'
            res10 = requests.post('https://ftx.us/api/wallet/withdrawals', data=prepared1.body, headers=prepared1.headers)
