python:对url api调用做简单负载均衡 因为我的服务大部分部署在了单机多个连续的端口中（如svc2 8100-8130端口），所以可以简单的做均衡。如果是多机多端口。那就另当别论了。 代码相当简单 ``` import random class UrlApiBalancer(object): def __init__(self): self.url = '' self.port_range=[0,0] def fill_url(self, *args): if not self.url: raise Exception('UrlApiBalancer url is empty') if not self.port_range[0] or not self.port_range[1]: raise Exception('UrlApiBalancer port_range is empty') url = self.url port = random.randint(self.port_range[0], self.port_range[1]) url = url.replace('{port}', str(port)) url = url.format(*args) return url url_blc = UrlApiBalancer() url_blc.url = 'http://www.superpig.win:{port}/{}/{}' url_blc.port_range = [8000, 8100] print(url_blc.fill_url('ha', 'ha')) ``` 来自 大脸猫 写于 2017-12-23 13:40 -- 更新于2020-10-19 13:06 -- 0 条评论
