Question

我已经成功部署了我的项目（sogou），但是当我运行它时：

curl http://localhost:6800/schedule.json -d project=sogou -d spider=sogou

失败了：

TypeError: __init__() got an unexpected keyword argument '_job'

Answer 1

如果没有源代码很难找到问题，但很可能会覆盖蜘蛛的__init__而不是它不接受任意**kwargs，而scrapyd将作业标识符作为spider参数传递。在这种情况下，您应该将**kwargs添加到蜘蛛的构造函数中，如下所示：

class Spider(scrapy.Spider):
    name = 'spider'

    def __init__(self, param1, param2, **kwargs):
        ...

运行scrapyd项目时出错
