在Visual Studio C中使用像beautifulSoup和请求的Python模块＃

Question

我想在visual studio中使用c＃运行外部python脚本。我使用像BeautifulSoup模块，并请求

但我收到以下错误

No module named requests 

早些时候，我收到了BeautifulSoup同样的错误，我添加下面一行到我的python脚本，并解决了这个错误

sys.path.append("[Path to Python]\Python\Python35-32\Lib\site-packages") 

我在Visual Studio 2015中使用IronPython。是否有反正我可以克服这个错误？如果这是不可能的，是否有其他方式在c＃环境中运行python脚本（使用上述模块）。

我试图使用denfromufa给出的解决方案，但后来我收到以下错误

这是我的Python代码

import sys 
import requests 
import re 
import io 
from bs4 import BeautifulSoup 
from math import floor 

r = requests.get("https://www.google.com/") 
data = r.text 
soup = BeautifulSoup(data, 'html.parser') 
result = [] 

for item in soup.find_all(attrs={'class' :'something'}): 
     for m in item.select('a[href^="something"]'): 

     m1 = m['href'].replace("something","",1) 

     m2 = re.sub(r'&.*$', "", m1) 

     m3 = re.sub(r'%3F.*$', "", m2) 

     m4 = m3.replace("%2F","/") 

     m5 = m4.replace("%3A",":") 

     result.append(m5) 
     result.append(m.get_text()) 


for image in item.find_all('img'): 
    k1 = re.sub(r'&cfs.*$',"",image['src']) 
    k2 = re.sub(r'^https://something.*$',"",k1) 
    k3 = re.sub(r'.*url=',"",k2) 
    k4 = re.sub(r'%3F.*$', "", k3) 
    k5 = k4.replace("%2F","/") 
    k6 = k5.replace("%3A",":") 
    k7 = re.sub(r'.*\.gif',"",k6) 
    result.append(k7) 



seen = set() 
result_final = [] 
for item in result: 
    if item not in seen: 
     seen.add(item) 
     result_final.append(item) 

result_final = list(result_final) 

我的C＃代码如下

using (Py.GIL()) 
       { 
        dynamic sys = Py.Import("sys"); 
       dynamic requests = Py.Import("requests"); 
       dynamic re = Py.Import("re"); 
       dynamic io = Py.Import("io"); 
       dynamic BeautifulSoup = Py.Import("bs4"); 
       dynamic math = Py.Import("math"); 
       Console.WriteLine(5); 
       dynamic r = requests.get("https://www.google.com/"); 
       dynamic data = r.text; 
       dynamic soup = BeautifulSoup.BeautifulSoup(data, "html.parser"); 
       } 

我用

var divExp = new { _class = "smoething" }; 
    var item = soup.find_all(Py.kw("class", divExp._class)); 

我收到结果。但是，当我尝试实施的项目变量的选择方法，我是个得到一个错误，说Python对象不包含“选择”

item.select("a[href^='https://www.google.com/']"); 

最终答案的定义

using (Py.GIL()) 
       { 
        dynamic sys = Py.Import("sys"); 
        dynamic requests = Py.Import("requests"); 
        dynamic re = Py.Import("re"); 
        dynamic io = Py.Import("io"); 
        dynamic BeautifulSoup = Py.Import("bs4"); 
        dynamic math = Py.Import("math"); 
        Console.WriteLine(5); 
        dynamic r = requests.get(url); 
        dynamic data = r.text; 
        dynamic soup = BeautifulSoup.BeautifulSoup(data, "html.parser"); 

        var divExp = new { _class = "className" }; 
        var item = soup.find_all(Py.kw("class", divExp._class)); 
        dynamic tag = soup.select("a[href^='https://something.com/']"); 
        for (var i = 1; i < item.Length(); i++) 
        { 
         // Extrxting the required info using regex 

         String input = Convert.ToString(item[i]); 
         string pattern_link = "(.*href=\"https:[\\/][\\/]something.com[\\/]a.php\\?u=)|(&.*)"; 
         string replacement_link = " "; 
         Regex rgx_link = new Regex(pattern_link); 
         string result_link = rgx_link.Replace(input, replacement_link); 

         . 
         . 
         . 
         . 
         string pattern_link_1 = "(http|https)%.*"; 
         Regex rgx_link_1 = new Regex(pattern_link_1); 
         Match result_link_1 = rgx_link_1.Match(result_link); 
         String input_1_1 = Convert.ToString(result_link_1.Value); 



         result_link_2 = result_link_2.Replace("%2F", "/").Replace("%3A", ":");      

        } 

       }

• 安装CPython的，2.7版本中的一个，在你的.NET项目安装Python.Runtime.DLL 3.4+
• pip install pythonnet
• 参考
• 请访问www.python4.net上的教程，嵌入部分。

为什么不使用HTML敏捷包？这是C＃的等价物。

您可以将其导入到您的解决方案。
