发生其他错误：应为值：第1行第1列（字符0）#1

Question

我写的API有问题。我的Json有一个错误，我觉得很奇怪。总体思路是搜索一组VIN并将其存储到Json文件中。代码工作到一个点，直到我存储第一个VIN，然后在第二个VIN上工作，但是我在标题中得到了错误。我知道我做错了什么，似乎问题在于保存数据。请在下面查找代码

api.py

import requests
import json
from requests.exceptions import HTTPError
#Define The VINs Lists
VINs = ['KPTGOC1FSCP300549', '5J6RM3H53CL015747', 'TDSY61U032248', 'JDAJ210GOO1052908', 'KNAKH812BA7683150', 'jtmbh31v806052793', 'Kmhsh81gdcu864966' ]

try:
    with open('vins.json', 'w') as f:
        for vin in VINs:
            response = requests.get(f'https://vindecodervehicle.com/api/v1/?id=xxxxxxx&key=xxxxxxx&vin={vin}')
            response.raise_for_status()
            # access JSOn content
            jsonResponse = response.json()
            #Create the json File.
            json.dump(jsonResponse, f, indent=4)
            print("Entire JSON response")
            print(jsonResponse)

except HTTPError as http_err:
    print(f'HTTP error occurred: {http_err}')
except Exception as err:
    print(f'Other error occurred: {err}')

正在存储的VIN文件。 vins.json

Answer 1

不要在打开的文件中多次转储。相反，您可以创建一个列表，将所有http_响应添加到该列表中，并一次性转储它

当您多次转储时，只需将多个字典（json记录）插入json文件中，而不在它们之间插入“，”并破坏语法

try:
    with open('vins.json', 'w') as f:
       http_responses = []
       for vin in VINs:
           response = requests.get(f'https://vindecodervehicle.com/api/v1/?id=xxxxxxx&key=xxxxxxx&vin={vin}')
            response.raise_for_status()
            # access JSOn content
            jsonResponse = response.json()
            http_responses.append(jsonResponse)
            print("Entire JSON response")
            print(jsonResponse)
       #Create the json File.
       json.dump(jsonResponse, http_responses, indent=4)

except HTTPError as http_err:
    print(f'HTTP error occurred: {http_err}')
except Exception as err:
    print(f'Other error occurred: {err}')
