从列表 json.decoder.JSONDecodeError : Expecting value: line 1 column 1 (char 0) 循环时出现 python 错误

Question

我正在制作一个脚本，用来自 api 的响应填充文本文档。 api 被要求将用户名从列表转换为通用唯一标识符。我不断收到此错误，但找不到解决方法。 “json.decoder.JSONDecodeError:期望值:第 1 行第 1 列(字符 0)”

    uuids = []
    uuids.append(uuid)

    file2 = open('uuids.txt', 'w')
    file2.writelines(uuids)
    file2.close()

    file2 = open('uuids.txt', 'r')
    lines = file2.readlines()

注意:@Ali 在检查空回复方面提出了一个很好的观点。有了这个修复，它对我来说就像一个冠军，还有其他一些小的变化:

使用 OP 提供的用户名，而不是从文件中读取它们。

移动了 uuids 的初始化跳出 for 循环以避免为每个用户名重置它。

将文件输入/输出内容修改为我更习惯使用的内容。 ;^)

import requests
import json

usernames = [
    "knapplace",
    "Coppinator",
    "tynow",
]

uuids = []
for x in usernames:

    username = str(x)

    url = ("https://api.mojang.com/users/profiles/minecraft/"+username+"?at=1462770000")

    y = requests.get(url)
    if len(y.content) == 0:
        continue  # Skip processing this username

    y_data = y.json()
    uuid = y_data['id']

    uuids.append(uuid)

with open('uuids.txt', 'w') as f:
    for uuid in uuids:
        f.write(uuid + '\n')

with open('uuids.txt', 'r') as f:
    read_data = f.read()

print(read_data)

输出:
