Question

这里是index.html模板中的html + js：http://pastie.org/8712901

问题是它在本地通过flask内置服务器运行时完全按照需要运行，但在使用apache wsgi部署时单击搜索按钮会出现500错误。

它在线（但没有功能） http://thekindlyone.scribblehead.info/calvinball/

帮助？

这里是追溯记录。

更新：我将whoosh索引目录路径设置为绝对路径，并将cnh.cbz路径设置为绝对路径。但即使在那之后我也得到了error。嗖的索引的东西虽然有效。是因为cnh.cbz文件在flask应用程序目录之外吗？我该如何解决？这是新的python

from flask import Flask, jsonify, render_template, request
from whoosh.index import open_dir
from whoosh.fields import *
from whoosh.qparser import QueryParser
from whoosh import highlight
import datetime
import zipfile
import logging
app = Flask(__name__)
app.logger.addHandler(logging.FileHandler('/home/webdev/thekindlyone/flasklogs/calvinball.log'))
#yymmdd

class database(object):
    def __init__(self,index_dir):
        self.ix=open_dir(index_dir)
    def search(self,text):
        fetched=[]
        brf = highlight.UppercaseFormatter()
        with self.ix.searcher() as searcher:
            query = QueryParser("content", self.ix.schema).parse(text)
            results = searcher.search(query)
            results.fragmenter=highlight.WholeFragmenter()
            results.formatter = brf
            for result in results:
                fetched.append((result['title'],result.highlights("content")))
        return fetched

def makehtml(tuples):
    hypertext=''
    if tuples:
        for title,content in tuples:
            ftitle=datetime.datetime.strptime(title[2:], '%y%m%d').strftime('%d/%m/%y')
            hypertext+='''<div class="clicker" id="{0}">{1}</div><br>'''.format(title,ftitle+'   '+content)           
    else:
        hypertext='Nothing found'

    return hypertext

@app.route('/search')
def find():   
    string = request.args.get('searchstring')    
    dbase=database('/home/webdev/thekindlyone/calvinball/index')
    hypertext=makehtml(dbase.search(string))
    return hypertext


@app.route('/')
def index():
    return render_template('index.html')

@app.route('/show')
def display():    
    strip = request.args.get('strip')
    z=zipfile.ZipFile('/home/webdev/thekindlyone/cnh.cbz')
    img=z.open(strip+'.jpg')
    z.close()
    data_uri = img.read().encode('base64').replace('\n', '')
    img_tag = '<img src="data:image/png;base64,{0}">'.format(data_uri)    
    return img_tag




if __name__ == '__main__':
    app.run(host='0.0.0.0',debug=True)

更新2：我为cnh.cbz创建了一个到应用程序目录的硬链接，它可以运行。但必须有更好的方法。

Answer 1

基于错误，您似乎需要对whoosh db使用绝对路径名，或者至少在打开它之前适当地设置当前目录。看来Apache没有将当前目录设置为应用程序的文件夹。

错误500与jquery ajax get和flask
