dic*_*bow 3 python flask stripe-payments
如果这对我来说是Python新手,那么这似乎是不成熟的.我试图完成的任务是将一个json对象从iPhone应用程序发送到将处理条带支付的python脚本.我遇到的问题是我无法弄清楚如何让Python识别传入的json对象从中提取数据并传递给Stripe.
我退后一步来简化问题.我有一个python脚本,试图将具有四个值对的json对象发布到另一个应该提取值的函数,创建一个新的json对象并返回该对象.我无法让它工作,任何帮助将不胜感激,因为我已经坚持了一段时间.我正在使用Flask:
`
import json
import stripe
import smtplib
import requests
from flask import Flask, request, jsonify
@application.route('/run_post')
def run_post():
url = 'http://xxx.pythonanywhere.com/stripetest'
data = {'stripeAmount': '199', 'stripeCurrency': 'USD', 'stripeToken': '122', 'stripeDescription': 'Test post'}
headers = {'Content-Type' : 'application/json'}
r = requests.post(url, data, headers=headers)
#return json.dumps(r.json(), indent=4)
return r.text
@application.route('/stripetest', methods=["POST"])
def stripeTest():
if request.method == "POST":
json_dict = json.loads(request.body.raw)
stripeAmount = json_dict['stripeAmount']
stripeCurrency = json_dict['stripeCurrency']
stripeToken = json_dict['stripeToken']
stripeDescription = json_dict['stripeDescription']
data = "{'stripeAmountRet': " + stripeAmount + ", 'stripeCurrencyRet': " + stripeCurrency + ", 'stripeTokenRet': " + stripeToken + ", 'stripeDescriptionRet': " + stripeDescription + "}"
return jsonify(data)
else:
return """<html><body>
Something went horribly wrong
</body></html>"""
`
运行时,我在错误日志中返回以下内容:
`

您对代码有几个问题.首先,您需要json在从requests库中发出请求时正确定义数据.你可以这样做:
@application.route('/run_post')
def run_post():
url = 'http://xxx.pythonanywhere.com/stripetest'
data = {'stripeAmount': '199', 'stripeCurrency': 'USD', 'stripeToken': '122', 'stripeDescription': 'Test post'}
headers = {'Content-Type' : 'application/json'}
r = requests.post(url, data=json.dumps(data), headers=headers)
#return json.dumps(r.json(), indent=4)
return r.text
请注意,我们调用json.dumps而不是直接传递数据.否则,传入请求不会被解释为json数据.
接下来,在您的接收函数中,我们将其更改如下:
@application.route('/stripetest', methods=["POST"])
def stripeTest():
if request.method == "POST":
json_dict = request.get_json()
stripeAmount = json_dict['stripeAmount']
stripeCurrency = json_dict['stripeCurrency']
stripeToken = json_dict['stripeToken']
stripeDescription = json_dict['stripeDescription']
data = {'stripeAmountRet': stripeAmount, 'stripeCurrencyRet': stripeCurrency, 'stripeTokenRet': stripeToken, 'stripeDescriptionRet': stripeDescription}
return jsonify(data)
else:
return """<html><body>
Something went horribly wrong
</body></html>"""
有些事情发生了变化.首先,我们通过调用读取数据request.get_json(),它正确地解析传入的json数据.请注意,我们需要更改实际请求它来正确解析数据的方式.下一个问题是您如何返回数据.为了正确jsonify返回数据,我们将数据放入python字典而不是字符串.
如果你正在调用你的函数来处理来自其他地方的条带支付(即不使用python requests库),另一个问题是你可能没有正确定义json请求以供Flask稍后解释.如果在对处理功能进行上述更改后问题仍然存在,请发布您在json其他地方提出请求的方式,我可以查看一下.
如果这可以解决您的问题,请告诉我!
