perf: 修复httpx.AsyncClient 每次构造时会同步创建 SSLContext #160
Description
- httpx.AsyncClient 每次构造时会同步创建 SSLContext (Blocking IO in AsyncClient init encode/httpx#3456)
- 将 SSL 上下文创建移至模块导入阶段 (UI 启动前), 消除实例化阻塞
_client = httpx.AsyncClient()
async def get_from_pypi(url: str) -> Optional[str]: # -> '1.8.0b1'
try:
req = await _client.get(url, timeout=5)
if req.status_code == 200:
return req.json().get("info", {}).get("version", None)
else:
return None
except Exception as e:
print(f"WARNING: Failed to check update from {url}", e)
return None
