Python 请求：没有名为“werkzeug.wrappers.json”的模块

Question

我正在尝试在 Python 中使用 requests 库，但是当我这样做时，我收到错误

    from werkzeug.wrappers.json import JSONMixin
ModuleNotFoundError: No module named 'werkzeug.wrappers.json'

下面是一个示例（使用我专门为此分叉的存储库，以及一个非常细粒度的访问令牌，该令牌很快就会过期，以防您担心我共享它）。

导入请求 导入 json

# GitHub API URL to create an issue in the crobarcro/Spoon-Knife repository
url = 'https://api.github.com/repos/crobarcro/Spoon-Knife/issues'

# Example payload for creating a GitHub issue
payload = {
    "title": "Test Issue from API",
    "body": "This is a test issue created via the GitHub API in the crobarcro/Spoon-Knife repository.",
    "assignees": [],  # You can assign this to specific users if needed
    "labels": ["bug"]  # Optional, you can add labels to the issue
}

# Headers with authentication (you need a GitHub token)
headers = {
    'Authorization': 'token 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',  # Replace with your GitHub token
    'Accept': 'application/vnd.github.v3+json',
    'Content-Type': 'application/json'
}

# Sending the POST request
response = requests.post(url, headers=headers, data=json.dumps(payload))

# Checking the response
if response.status_code == 201:
    print('Issue created successfully:', response.json())
else:
    print(f'Failed to create issue. Status code {response.status_code}:', response.text)

Answer 1

虽然我不太清楚为什么 requests 库导入 werkzeug，但我知道

werkzeug.wrappers.json

导入已从 werkzeug 库中弃用。如果您需要它，您可以通过以下方式将 werkzeug 降级到旧版本：

pip install "werkzeug<1"

更好的解决方案可能是检查您的请求库版本，并根据该版本的文档实现您的脚本。
