Python 获得；“请求太多”；使用scrapy刮取特定网站时出错

我写了一个蜘蛛来从他那里获取细节。 每次我试图放弃，我都会得到一个回应

Too many requests, please try after some time or report this problem at contact@allevents.in

我也尝试过使用shell命令

 scrapy shell 'http://allevents.in/new%20delhi/all'

但我还是得到了与

response.body

相同的响应。 我也尝试过其他类似的网站，效果很好。 此外，还可以使用

请求

以及

urllib.urlopen（）

获取上述url

这是我的

settings.py

我是学刮痧的初学者。请帮助

Scrapy使用多个并发请求（默认为8个）来废弃您指定的网站。似乎allevents.in不喜欢你打得太多

最有可能的解决方案是设置以下配置选项之一：

• 每个域的并发请求（默认为8，尝试使用较小的数字）

• 每个IP的并发请求（默认为0，如果设置为正数，则覆盖上一个请求）

或者，您也可以在

并发请求=1

中使用.

Hi try assignment，如果您看到它有效，则逐渐增加它，如果仍然收到相同的警告，请尝试设置更高的

下载延迟

使用

刮擦随机代理

，而不是应用自动油门，当你能以更高的速度实现目标时，限制爬虫程序是没有乐趣的-相信我，如果你使用几百个代理{more always better}，他们永远不会知道你在哪里。

基本上，他们所有的事件都必须跟踪你的报废程序，作为预防措施，他们可能会阻止你源系统的ip地址。在您的终端，它的allevents服务没有任何问题，它已经禁用了您的爬行器。您可以更改您的IP，并检查是否可能。我已尝试使用不同的IP。但是仍然得到相同的输出@Maheshkariat还有更多的事情需要考虑，比如客户端类型、请求等，所以在这一点上我们真的不知道他们阻止的所有标准。我如何设置？我尝试过使用scrapy shell@yorah。您可以使用以下语法向scrapy shell传递命令行选项：scrapy shell-s CONCURRENT_REQUESTS_PER_DOMAIN='8'http://...Also，如果从项目路径启动scrapy shell，然后你的项目设置应该会自动被使用。我已经尝试了并发请求\u PER\u DOMAIN=1仍然是相同的错误基本上，网站告诉你：“不要对我太严厉”。通过将每个域的并发请求设置为1，您将连接数限制为1。您还可以尝试设置选项

DOWNLOAD\u DELAY=5

，以设置这些请求之间的5秒延迟（可以随意增加/减少此值以找到最佳值）。
