我的HTML表打印\ u0027而不是撇號

我正在用Python和燒瓶製作網站，並在我的HTML表格中打印： Rory O\u0027Shea Was Here而不是Rory O'Shea Was Here。我的HTML表打印 u0027而不是撇號

當我在終端上運行Python程序時，它會打印出來很好，但是當我將它放到我的HTML模板中時，它會打印出\u0027。

我怎樣才能打印預期的Rory O'Shea Was Here？

這裏是main.py（運行燒瓶應用）：

from flask import Flask, render_template, request 
from hboA import HbobyRating 

app = Flask(__name__) 

@app.route("/hbo") 
def hbo(): 
    name = "HBO" 
    logo = "/static/pics/hbo-logo.jpg" 
    hbomovies = HbobyRating 
    db = hbomovies 
    return render_template('channel_template.html', hbomovies=hbomovies, name=name, db=db, logo=logo)

這裏是imdbHbo.py（這產生使用IMDB API電影數據庫）：

import json 
import urllib2 


with open('/home/chim/Documents/moveit/hbomovies.json') as data_file: #opens the movie database from Guidebox api 
    moviedata = json.load(data_file) 

Id = [x['imdb'] for x in moviedata['results']]    #extracts the imdbid from guidebox api 

pyList = [] 
def getMovieRating():       #creates a new json file containing the imdb data from the channels of guidebox api 
    for i in Id: 
     imdbid = i  
     imdbapi = "http://www.omdbapi.com/?i=%s&plot=short&r=json" % imdbid 
     response = urllib2.urlopen(imdbapi) 
     result = json.load(response) 
     pyList.append(result) 
     with open('/home/chim/Documents/moveit/static/hboImdb.json', 'w') as outfile: 
       json.dump(pyList, outfile) 

getMovieRating()

這裏是hboA.py python（這種將電影按其IMDB評級排列成列表）：

import json 


with open('/home/chim/Documents/moveit/final/hboImdb.json') as data_file: #opens the imdb database we created 
    response = json.load(data_file) 


def getKeyRat(item): 
    return item[1] 

def getKeyAlpha(item): 
    return item[0] 



TitleRating = [[x["Title"].encode('utf-8'), x['imdbRating'], x['Year'], x['Rated'], x['Genre'], x['Runtime']] for x in response] 


for each in TitleRating: 
    each.append("HBO") 


HbobyRating = sorted(TitleRating, key=getKeyRat, reverse=True) 
HbobyAlpha = sorted(TitleRating, key=getKeyAlpha)

這裏是HTML：

<!DOCTYPE html> 


<img src={{logo}} alt="logo" style="width:512px;height:320px;" align="right"> 
<head> 
    <title>Welcome to MoveIt</title>

<p> Or see a list by channel</p>

    <tr>

    </tr> 
{% endfor %} 
</table>

你如何將這個字符串傳遞給你的模板？它來自哪裏？數據庫？用戶輸入？ – IanAuld

它來自一個json文件，它被解析成一個列表到我的python文件中。 –

你在哪裏編寫你的html？顯示代碼。 – Daniel

你在不同的地方有你的代碼的問題。

首先，爲什麼用utf-8編碼Title？內部字符串必須使用Unicode，只寫入一個流時，編碼是必要的：

import json 
from operator import attrgetter 

DATABASE = '/home/chim/Documents/moveit/final/hboImdb.json' 

def read_database(database): 
    with open(database) as data_file: #opens the imdb database we created 
     response = json.load(data_file) 

    hbo_by_rating = sorted(response, key=attrgetter('imdbRating'), reverse=True) 
    hbo_by_alpha = sorted(response, key=attrgetter('Title')) 
    return hbo_by_rating, hbo_by_alpha 

hbo_by_rating, hbo_by_alpha = read_database(DATABASE)

接下來，在你的模板，你說明確「的toJSON」的逃逸每個非ASCII字符爲Unicode \uxxxx。只需刪除它：

<h2>These are the movies on {{name}} <i>right now</i>, listed by their IMDB rating:</h2> 
<table border="1"> 
<tr> 
    <th>Title</th> 
    <th>Imdb Rating</th>   
    <th>Year</th> 
    <th>Rated</th> 
    <th>Genre</th>  
    <th>Runtime</th> 
    </tr> 
{% for row in db %} 
    <tr> 
     <td>{{ row.Title }}</td> 
     <td>{{ row.imdbRating }}</td> 
     <td>{{ row.Year }}</td> 
     <td>{{ row.Rated }}</td> 
     <td>{{ row.Genre }}</td> 
     <td>{{ row.Runtime }}</td> 
    </tr> 
{% endfor %} 
</table>

這樣做了！這是'tojson'的東西，它搞砸了，我只是刪除它。多謝你們！ –

您需要在上傳之前對其進行編碼。使用foo.encode('utf-8')其中foo是包含字符串的變量。

當我這樣做時，它將終端中的python輸出更改爲：「Rory O'Shea在這裏」而不是「u'Rory O'Shea在這裏」，但html看起來一樣... –
