好几个月之前，我用 node.js 部署了一个 api，然后用树莓派 python 调用竟然失败了，没找到原因，就搁置了
最近写 React Native 项目
同一个 api https://hongweizhu.com:3000/x_mood
Android 模拟器和真机请求失败
iOS 及模拟器请求成功
Postman 请求成功
Raspberry 请求失败（但是跳过 SSL 证书验证可以请求成功，用的阿里云申请的免费证书）
import requests
url = 'https://hongweizhu.com:3000/x_mood'
# 根据实际情况构造请求体，这里是一个示例
payload = {
'title': '今日心情',
'mood': '开心',
'content': '今天阳光明媚，心情很好。',
}
# 如果需要身份验证或 token，可以在 headers 中添加
headers = {
'Content-Type': 'application/json',
# 'Authorization': 'Bearer YOUR_TOKEN_HERE', # 如有需要
}
# 添加 verify=False 来跳过 SSL 证书验证
response = requests.post(url, json=payload, headers=headers, verify=False)
# 打印响应内容
print(f'Status code: {response.status_code}')
try:
print('Response:', response.json())
except Exception as e:
print('Response text:', response.text)
print('Error parsing JSON:', e)

然后把 apche 配置 ssl 的部分发给 AI
# SSL Engine Switch:
# Enable/Disable SSL for this virtual host.
SSLEngine on
# A self-signed (snakeoil) certificate can be created by installing
# the ssl-cert package. See
# /usr/share/doc/apache2/README.Debian.gz for more info.
# If both key and certificate are stored in the same file, only the
# SSLCertificateFile directive is needed.
# SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem
# SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
SSLCertificateFile /etc/apache2/ssl/hongweizhu.com_public.crt
SSLCertificateKeyFile /etc/apache2/ssl/hongweizhu.com.key
没有设置中间证书链（SSLCertificateChainFile）
没有配置 chain.crt 哈哈哈哈哈
以前我想过，怎么申请的证书解压后有 3 个文件
而 apache 示例代码只给了两个，之前就配置了两条，web 浏览器，iOS 用没问题，就没管第三个文件

直到现在树莓派请求失败，android 请求失败。。。。。。
就这样吧，哈哈哈哈哈
希望对你有些帮助。
