大家！

我是 Scrapy 框架的新手。我需要解析wisemapping.com。起初，我阅读了官方的 Scrapy 教程并尝试访问其中一个“wisemap”，但出现错误：

[scrapy.core.engine] DEBUG: Crawled (404) <GET https://app.wisemapping.com/robots.txt> (referer: None)

[scrapy.downloadermiddlewares.retry] DEBUG: Gave up retrying
<GET https://app.wisemapping.com/c/maps/576786/public> (failed 3 times): 500 Internal Server Error

[scrapy.core.engine] DEBUG: Crawled (500) <GET https://app.wisemapping.com/c/maps/576786/public> (referer: None)

[scrapy.spidermiddlewares.httperror] INFO: Ignoring response <500 https://app.wisemapping.com/c/maps/576786/public>: HTTP status code is not handled or not allowed

请给我一个建议，用以下代码解决问题：

import scrapy

class QuotesSpider(scrapy.Spider):
    name = "quotes"

    def start_requests(self):
        urls = [
            'https://app.wisemapping.com/c/maps/576786/public',
        ]
        for url in urls:
            yield scrapy.Request(url=url, callback=self.parse)

    def parse(self, response):
        page = response.url.split("/")[-2]
        filename = 'wisemape.html'
        with open(filename, 'wb') as f:
            f.write(response.body)
        self.log('Saved file %s' % filename)

【解决方案1】：

导航到https://app.wisemapping.com/c/maps/576786/public 会出现错误 “Outch！！。这张地图已经不可用了。您没有足够的权限查看此地图。此地图已更改为私人地图或已删除。”

这张地图存在吗？如果是这样，请尝试将其公开。

如果您确实知道您尝试访问的地图存在，请验证您尝试访问的 URL 是否正确。
