python - 向我的 RESTful API(Python-Flask) 发送 POST 请求，但收到 GET 请求

Question

我正在尝试以包含 JSON 的 POST 请求的形式向 Zapier webhook 发送触发器。如果我只是通过本地 python 脚本发送 POST 请求，它就可以正常工作。

我想做的是创建一个 RESTful API，它在调用 create-row-in-gs 端点时触发 Zapier webhook。

如您所见，我正在向 Hasura 集群发送 POST 请求 API 调用。但是我得到的不是“200 OK SUCCESS”的响应，而是“200 OK 失败”，这意味着该请求被视为 GET 请求而不是 POST 请求。

测试.py

#Python 3 Script to send a POST request containing JSON

import json
import requests

api_url = 'http://app.catercorner16.hasura-app.io/create-row-in-gs'
create_row_data = {'id': '1235','name':'Joel','created-on':'27/01/2018','modified-on':'27/01/2018','desc':'This is Joel!!'}
r = requests.post(url=api_url, data=create_row_data)
print(r.status_code, r.reason, r.text)

server.py(运行在Hasura集群上)

from src import app
from flask import jsonify,request,make_response,url_for,redirect
from json import dumps
from requests import post

url = 'https://hooks.zapier.com/hooks/catch/xxxxx/yyyyy/'

@app.route('/create-row-in-gs', methods=['GET','POST'])
def create_row_in_gs():
    if request.method == 'GET':
        return make_response('failure')
    if request.method == 'POST':
        t_id = request.json['id']
        t_name = request.json['name']
        created_on = request.json['created_on']
        modified_on = request.json['modified_on']
        desc = request.json['desc']

        create_row_data = {'id': str(t_id),'name':str(t_name),'created-on':str(created_on),'modified-on':str(modified_on),'desc':str(desc)}

        response = requests.post(
            url, data=json.dumps(create_row_data),
            headers={'Content-Type': 'application/json'}
        )
        return response

几周来一直在努力解决这个问题。我究竟做错了什么？非常感谢任何帮助。

好的，我在本地检查了您的脚本，发现了两个问题。两者都在您的客户端脚本中。

1) r = requests.post(url=api_url, data=create_row_data) 应该是 r = requests.post(url=api_url, json=create_row_data)

2) 您在您的 Flask 应用程序中查找 created_on 和 modified_on，但是您发送了 created-on 和 modified-on 。

下面的工作本地代码:

客户:

import json
import requests

api_url = 'http://localhost:5000/create-row-in-gs'
create_row_data = {'id': '1235','name':'Joel','created_on':'27/01/2018','modified_on':'27/01/2018','desc':'This is Joel!!'}
print(create_row_data)
r = requests.post(url=api_url, json=create_row_data)
print(r.status_code, r.reason, r.text)

服务器:

from flask import Flask,jsonify,request,make_response,url_for,redirect
import requests, json

app = Flask(__name__)

url = 'https://hooks.zapier.com/hooks/catch/xxxxx/yyyyy/'

@app.route('/create-row-in-gs', methods=['GET','POST'])
def create_row_in_gs():
    if request.method == 'GET':
        return make_response('failure')
    if request.method == 'POST':
        t_id = request.json['id']
        t_name = request.json['name']
        created_on = request.json['created_on']
        modified_on = request.json['modified_on']
        desc = request.json['desc']

        create_row_data = {'id': str(t_id),'name':str(t_name),'created-on':str(created_on),'modified-on':str(modified_on),'desc':str(desc)}

        response = requests.post(
            url, data=json.dumps(create_row_data),
            headers={'Content-Type': 'application/json'}
        )
        return response.content

if __name__ == '__main__':
    app.run(host='localhost',debug=False, use_reloader=True)
