烧瓶请求中的http请求

Question

我从http请求访问响应数据时遇到问题。如果我将响应传递给html，然后从中获取想要的特定数据，但如果我尝试在python文件中获取响应的同一部分并将其传递给html，我就能得到它。它说“字典中没有book属性”。

我的html

{% extends "layout.html" %}

{% block heading %}
Search Page
{% endblock %}


{% block body %}

the result of the http request:
<p>  {{res}} </p>


I want to add this info from the request
<p>{{res.books[0].average_rating}}
{{res.books[0].work_ratings_count}}</p>


to this dictionary

{{apiDict}}

but the when I use the same syntax to access the average rating and ratings count 
from 
'res' in my python file it says the respose has no book object, why does this 
happen?

{% endblock %}

这是我的python /烧瓶代码：

@app.route("/api/<isbn>", methods=["GET"])
def apiacc(isbn):
res = requests.get("https://www.goodreads.com/book/review_counts.json", params=. 
{"key": "lzhHXUd9kUpum244vufV2Q", "isbns": isbn}).json()
# avg = res.books[0].average_rating
# rc = res.books[0].work_ratings_count
book = db.execute("SELECT * FROM books WHERE isbn = :i", {"i": isbn}).fetchone()
db.commit()


apiDict = {
    "title": book.title,
    "author": book.author,
    "year": book.year,
    "isbn": isbn
}
# apiDict["average_score"] = res.books[0].average_rating
# apiDict["review_count"] = res.books[0].work_ratings_count

return render_template("api.html", res = res, apiDict=apiDict)

我想拥有这样的python代码：

 apiDict = {
    "title": book.title,
    "author": book.author,
    "year": book.year,
    "isbn": isbn,
    "average_score": avg,
    "review_count": rc
 }

并且仅将apiDict传递给api.hmtl作为唯一值，但是我得到了前面提到的错误。enter image description here

请求返回的res将是字典。在模板中，Jinja支持使用点运算符获取dict值，例如：

{{ res.books }}

但是在Python中，必须使用方括号运算符来获取字典中的值（用于获取属性的点运算符：]

data = res['books']
