定位到的有关代码

最后一行

即使把所有的链接改为 https，仍会爆出下面的错误，如何解决呢？

在校外，没有公网的网址，需要用用户名和账号登陆才能下载，这个咋搞啊

采了一百多篇，验证码出问题，提示：
ERROR:root:出现验证码
Traceback (most recent call last):
File "main.py", line 144, in parse_page
tr_table.tr.extract()
AttributeError: 'NoneType' object has no attribute 'tr'

用不用识别码都报错，请帮忙看一下是什么原因？谢谢

实现了学校ip的知网登录但下载文献需要验证码（每一篇都要），真实的浏览器（selenium驱动浏览器也每篇都要验证码）请求可以直接下载到文献，是少量什么参数还是什么？
看了下CNKI-download的文献下载部分只是简单的get请求加了headers是一个404

这个该怎么解决啊？ 博主，希望可以解答一波！！！！！！！！谢谢！！！

我记得知网有个api,选定了是否是pdf文件还是caj文件，caj比较恶心，而且类型还不是所有的软件都支持打开

/kns/download?filename=5UjSyB3SXd0N18mWrImTGNVYTxETNF0QZhXMWl3R2RVTHRnYIVjRuBzT6dmarVEa5gHVGJEeCplQHJETrZ2Q40UQMVmeTNTZTFEM4cnerglV0hDOoVGVI5WRR5mWod2VilUZ2V2QFN1dqJ2ZKtSMZR0LrFWW1t0U&tablename=CAPJLAST&dflag=pdfdown

dflag=pdfdown 这个是pdf的下载链接
dflag=cajdown 这个是caj的下载链接
除此之外其余的参数就没什么区别了

我从github上下载项目配置完成后 得到.caj文件打开是网页源代码 而不是caj文档

在具体使用过程中，我发现程序在指定文献期刊来源后，只能检索到期刊内容，无法检索到非期刊文献。例如将文献期刊来源设定为"xx大学"，检索结果的来源为“xx大学学报”，数据库为“期刊”。有没有什么方法能检索到硕博士论文？
读过代码后发现，该检索条件传入的参数为“'magazine_value1”，我想要修改此处的参数，尝试了几种方法但是没找到具体该传入什么参数。个人对爬虫和网络相关知识的相当浅薄，想知道此处应该如何修改？感谢大佬

报错信息：
在检索文件信息时，会出现”NoneType...find_all(‘a’)”的报错
解决办法：
我加了一个if判断如果find不到需要的信息（作者单位）就跳过，发现生成的excel里面都没有摘要和关键字了
问题猜测：
我打印了爬取到的soup，发现爬取到的html里面都没有摘要（在网页上查找同样的文章是存在摘要的），想问下作者是不是知网的接口又变了，因为对爬虫的了解很肤浅，真诚希望作者大大百忙之中解答一下，谢谢！

知网改了网页源代码，将搜索后包含内容的

问题描述

直接fork到的代码不是直接能用的
然后修改了一下

    def depoint(self, img):
        """传入二值化后的图片进行降噪"""
        pixdata = img.load()
        w, h = img.size
        for y in range(1, h - 1):
            for x in range(1, w - 1):
                count = 0
                if pixdata[x, y - 1] > 245:  # 上
                    count = count + 1
                if pixdata[x, y + 1] > 245:  # 下
                    count = count + 1
                if pixdata[x - 1, y] > 245:  # 左
                    count = count + 1
                if pixdata[x + 1, y] > 245:  # 右
                    count = count + 1
                if pixdata[x - 1, y - 1] > 245:  # 左上
                    count = count + 1
                if pixdata[x - 1, y + 1] > 245:  # 左下
                    count = count + 1
                if pixdata[x + 1, y - 1] > 245:  # 右上
                    count = count + 1
                if pixdata[x + 1, y + 1] > 245:  # 右下
                    count = count + 1
                if count > 4:
                    pixdata[x, y] = 255
        return img

    def imge2string(self,image,threshold):
        """
        图片转字符串
        按照threshold进行降噪
        """

        image = image.convert('L')
        # 二值化
        image = image.point(lambda x: 255 if x > threshold else 0)
        #
        # 继续降噪
        image = self.depoint(image)
        # 识别//这里识别还有问题 tesserocr识别内容为空
        result = tesserocr.image_to_text(image)
        print(str(threshold)+"识别到验证码：" + str(result))
        return result

    def crack_code(self):
        '''
        自动识别验证码
        '''
        image = Image.open('./data/crack_code.jpeg')
        # 转为灰度图像

        # 设定二值化阈值
        threshold = 127
        s1 = self.imge2string(image, threshold)
        s2 = self.imge2string(image, threshold+20)
        s3 = self.imge2string(image, threshold-20)
        if s1 == s2 == s3 or s1 == s2 or s1 == s3:
            return self.send_code(str(s1))
        elif s2 == s3:
            return self.send_code(str(s2))

在result = tesserocr.image_to_text(image)这里出现了问题
无论如何识别，或者处理图像，tesserocr返回结果均为空

是否需要规定文献来源（y/n）？n

求助大佬

修改的地方就是http改成了https，其他没有动过，但是下载下来都是2kb，打开显示已损坏
