PyLoom，爬龙！ 2 | 3 | PyLoom想为有价值的网站编写爬虫，让开发者便捷地获取结构化的数据。 4 | 5 | PyLoom由三个部分组成， 6 | 7 | 1. 框架，减少编写、运行、维护爬虫的工作量。 8 | 9 | 2. 爬虫，寻找有价值的目标为其开发爬虫，并维护既有爬虫的可用性。 10 | 11 | 预期19年底，PyLoom将拥有围绕电子商务、房屋租售、社交网络、新闻媒体的数十个爬虫。 12 | 13 | 3. 升级爬虫，对于频繁使用的爬虫，增强其能力 14 | + 增强定制能力，例如支持限定地区、类别、关键字抓取； 15 | + 增强抓取策略，减少对代理、打码接口的使用； 16 | + 增强更新策略，更细粒度地计算重复抓取的时间。 17 | 18 | 目前进度， 19 | 20 | ①部分完成，开发常见爬虫够用了，随爬虫的开发迭代出更多功能； 21 | 22 | ②已有几款爬虫，放置于`spiders`目录。 23 | 24 | 25 | 26 | ## 安装 27 | 28 | 1. **环境要求** 29 | 30 | + python 3.6.0+ 31 | + redis 2.6+ 32 | + 类unix系统 33 | 34 | 2. **安装PyLoom** 35 | 36 | ```bash 37 | git clone https://github.com/spencer404/PyLoom.git 38 | python3.6 -m pip install -e ./PyLoom 39 | ``` 40 | 41 | > 添加 `-i https://pypi.douban.com/simple` 参数，利用豆瓣镜像提速。 42 | 43 | >出现错误`fatal error: Python.h: No such file or directory`时， 44 | > 45 | >需安装对应平台的python3.x-devel包 46 | > 47 | 48 | 49 | 50 | ## 运行 51 | 52 | 以运行`spiders/WeiBo`为例， 53 | 54 | 1. **最简参数启动爬虫** 55 | 56 | ```bash 57 | pyloom run -s PyLoom/spiders/WeiBo 58 | ``` 59 | 60 | >在爬虫目录中执行`run`时，可省略`-s`参数。 61 | 62 | 2. **启动代理池** 63 | 64 | ```bash 65 | pyloom proxy run 66 | ``` 67 | 68 | 3. **添加代理** 69 | 70 | 根据命令提示，添加名为"xxx"的代理 71 | 72 | ```bash 73 | pyloom proxy add 74 | ``` 75 | 76 | 4. **使用代理启动爬虫** 77 | 78 | ```bash 79 | pyloom run --proxy xxx 80 | ``` 81 | 82 | 命令`run`的部分常用参数： 83 | 84 | ```bash 85 | -l, --level 日志级别 86 | -s, --spider 指定爬虫目录 87 | -r, --redis 指定redis地址(URL形式) 88 | -C, --clear 清空队列、代理数据后运行 89 | --proxy 使用指定代理运行，逗号分隔多个代理 90 | --damon 作为守护进程运行 91 | -p 子进程数量 92 | -t 每个子进程的线程数量 93 | ``` 94 | 95 | 在多台服务器上运行时，若参数`-s、-r`所指向的目标相同，即可横向扩容性能。 96 | 97 | 默认地，PyLoom将抓到数据打印在日志中，你可以修改`on_save`函数自定义如何保存。 -------------------------------------------------------------------------------- /pyloom/errors.py: -------------------------------------------------------------------------------- 1 | class TaskError(Exception): 2 | """ 3 | Task生命周期中出现的异常 4 | 若某Task抛出此异常，当前URL将被加入异常队列（error） 5 | """ 6 | 7 | def __init__(self, tag): 8 | self.err = f"TaskError('{tag}')" 9 | 10 | def __str__(self): 11 | return self.err 12 | 13 | 14 | class TaskFinish(Exception): 15 | """提前结束生命周期，并将当前URL加入布隆过滤器""" 16 | 17 | 18 | class TaskBreak(Exception): 19 | """提前结束生命周期，并将当前URL归还到任务队列""" 20 | 21 | def __init__(self, priority=0): 22 | """ 23 | Args: 24 | priority: 指定队列优先级 25 | """ 26 | self.priority = priority 27 | 28 | 29 | class RetryExceeded(TaskError): 30 | """重试次数超限""" 31 | 32 | def __init__(self): 33 | self.err = "RetryExceeded" 34 | 35 | 36 | class RequestError(Exception): 37 | """请求异常""" 38 | 39 | 40 | class Timeout(RequestError): 41 | """请求超时""" 42 | 43 | 44 | class ProxyError(Exception): 45 | """代理异常""" 46 | 47 | 48 | class RetryError(Exception): 49 | """重试错误，需搭配tasks.retry装饰器使用""" 50 | 51 | 52 | class JSONDecodeError(ValueError): 53 | """使用Response().json时出现解码错误""" 54 | 55 | 56 | class DebuggerError(Exception): 57 | pass 58 | 59 | 60 | class SchedulerError(Exception): 61 | pass 62 | 63 | 64 | class ConfigError(Exception): 65 | def __init__(self, name, err=None): 66 | self.name = name 67 | self.err = err 68 | 69 | def __str__(self): 70 | s = f"配置'{self.name}'有误" 71 | if self.err is not None: 72 | s += f", {self.err}" 73 | return s 74 | 75 | 76 | class ConfigFileNotFoundError(ConfigError, FileNotFoundError): 77 | def __init__(self, file): 78 | self.file = file 79 | 80 | def __str__(self): 81 | return f"未找到配置文件:'{self.file}'" 82 | 83 | 84 | class ConfigNotNone(ConfigError, ValueError): 85 | def __init__(self, name): 86 | self.name = name 87 | 88 | def __str__(self): 89 | return f"缺少配置项:'{self.name}'" 90 | 91 | 92 | class BucketError(Exception): 93 | pass 94 | -------------------------------------------------------------------------------- /.gitignore: -------------------------------------------------------------------------------- 1 | ### Python template 2 | #
