如何从 API 响应中捕获所有故障节点

Question

对于每个发出的请求，都会给出响应。我的目标是捕获所有返回 false 的节点。目前我只能存储最后一个响应。

下面是失败响应的示例：

<?xml version="1.0" encoding="utf-8"?>
<lead_return_response xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://lead.com/api/2/">
  <success>false</success>
  <message>Lead is Already in Return List</message>
</lead_return_response>

这是我的代码块：

import requests
import json
import csv
from bs4 import BeautifulSoup

def return_leads():
    with open('return_leads.csv', 'r') as csv_file:  #opens csv file as var csv_file
        csv_reader = csv.DictReader(csv_file)  #csv.Dictreader turns values from csv 'returns_lead.csv' and converts to key values pairs
        for data in csv_reader:  #looping through data in csv file
            url = 'https://api.com.'  #request URL for API
            params={"api_key": "#########",  #api key is only static value
                    "lead_id": data['Lead ID'],  #passing dynamic values from csv to required API parameters
                    "vertical_id": data['Vertical ID'],
                    "buyer_contract_id": data['Buyer Contract ID'],
                    "return_type": data['Return Type'],
                    "return_reason_id": data['Return Reason ID'],
                    "reject_reason_id": data['Reject Reason ID']}
            req = requests.get(url, params=params)  #request is generated for each line item in the csv file
            print(req.text) #response from API request is captured
#Print Output:
<?xml version="1.0" encoding="utf-8"?>
<lead_return_response xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://cakemarketing.com/api/2/">

            print(url, params) #check how params are being populated with dynamic data

            response = BeautifulSoup(req.text, 'lxml')
            print('response:', response)
            responseFalse = response.find('success').string
            responseMessage = response.find('message').string
            if responseFalse == 'false':
                captureResponse = []
                captureResponse.append(data['Lead ID'])
                captureResponse.append(responseFalse)
                captureResponse.append(responseMessage)
print('caputureResponse:', captureResponse)
#Print Output:
 ['9B45E52E', 'false', 'Lead is Already in Return List']
return_leads()

我的目标是让 captureResponse[] 包含所有失败的 3 个潜在客户，而不仅仅是最后一个潜在客户。谁能纠正我在这里做错了什么？提前谢谢你！

Answer 1

只需初始化一次

请初始化函数顶部附近的列表：

def return_leads():
    captureResponse = []
    with open( ...

您的代码正在函数中初始化它，在for回路内，在测试中为假。

效果是将一个非常好的值 #1 放入列表中，然后我们将列表设置为 []然后在其中输入一个非常好的值 #2。并再次将其重置为值 #3 输入之前的[]。

数据结构

此外，三个.append()调用可能不是您想要的。构造一个元组并附加以下内容会更有意义：

            captureResponse.append((data['Lead ID'], responseFalse, responseMessage))

元组在单独的行上分解时可能更清晰：

            summary = data['Lead ID'], responseFalse, responseMessage
            captureResponse.append(summary)
