我尝试使用aiohttp从url获取查询字符串参数,但此代码不起作用:
async def call_answer(request):
print("request", request)
params = request.rel_url.query
print("parameters +++++", params["call_id"])
conn = psycopg2.connect(connect_str)
cursor = conn.cursor()
sql = """
update calls
set status = %s
where id = %s;
""" % (params["status"], params["call_id"])
cursor.execute(sql)
conn.commit()
return web.Response(
content_type='application/json',
text=json.dumps({
'status': 'success'
}))
if __name__ == '__main__':
parser = argparse.ArgumentParser(description='WebRTC audio / video / data-channels demo')
parser.add_argument('--port', type=int, default=8080,
help='Port for HTTP server (default: 8080)')
parser.add_argument('--verbose', '-v', action='count')
args = parser.parse_args()
if args.verbose:
logging.basicConfig(level=logging.DEBUG)
app = web.Application()
app.router.add_get('/{call_id}&{status}', call_answer)
我在互联网上搜索过,写的是你应该使用request.rel_url.query从查询字符串中获取所有参数,但是在运行代码时出错!!!!!
答案 0 :(得分:1)
您不能将查询字符串添加到路由规范中,因为aiohttp会在路由匹配时抛弃查询字符串。 request.rel_url.query
效果很好,这是一个例子:
from aiohttp import web
async def call_answer(request):
params = request.rel_url.query
return web.Response(text='\n'.join([
'call_id = ' + params['call_id'],
'status = ' + params['status'],
]))
app = web.Application()
app.router.add_get('/', call_answer)
web.run_app(app)
测试它:
$ curl 'localhost:8080/?call_id=100&status=200'
call_id = 100
status = 200
