我想将数组传递给瓶子的模板并显示其内容

Question

环境

・Python 3.6.0

・瓶子 0.13-dev

・mod_wsgi-4.5.15

在网络上尝试以下代码会导致 500 个错误

500 Internal Server Error

app/wsgi

# -*- coding:utf-8 -*-
import sys, os
dirpath = os.path.dirname(os.path.abspath(__file__))
sys.path.append(dirpath)
sys.path.append('../')
os.chdir(dirpath)
import bottle
import index
application = bottle.default_app()

index.py

from urllib.request import urlopen
from bs4 import BeautifulSoup
from bottle import route, view

@route('/')
@view("index_template")
def index():
    html = urlopen("https://en.wikipedia.org/wiki/Kevin_Bacon")
    internalLinks=[]
    bsObj = BeautifulSoup(html, "html.parser")
        for link in bsObj.findAll("a"):
            if 'href' in links.attr:
                internalLinks.append(links.attr['href'])
    return dict(internalLinks=internalLinks)

Answer 1

日志报告 IndentationError，因此您的代码中的缩进有问题：具体来说，for 循环过度缩进，for 语句应位于与 bsObj 作业相同级别。

您还需要使您的变量名称保持一致 (link|links) 并使用 attrs 属性，而不是 attr。固定代码如下（未经测试）。

@route('/')
@view("index_template")
def index():
    html = urlopen("https://en.wikipedia.org/wiki/Kevin_Bacon")
    internalLinks=[]
    bsObj = BeautifulSoup(html, "html.parser")
    for link in bsObj.findAll("a"):
        if 'href' in link.attrs:
            internalLinks.append(link.attrs['href'])
    return dict(internalLinks=internalLinks)
