Question

我正在尝试从stackoverflow API获取数据并将其显示在我模板中的html表中。

到目前为止，我已设法获取数据，但无法在模板中显示它们。我最终得到了最后一个。我知道我的循环是错误的，尝试了一堆东西，但似乎无法搞清楚。

到目前为止我的代码：

def get_questions(request):
    context = {}
    r = requests.get('https://api.stackexchange.com/2.2/questions?fromdate=1525737600&order=desc&sort=activity&tagged=python&site=stackoverflow').json()
    for item in r['items']:
        context['owner'] = item['owner']['display_name']
        context['title'] = item['title']
        #some other attrs here

    template = 'questions/questions_list.html'
    context['greeting'] = 'Hello'

    return render(request,template,context)

我的模板代码：我还没做过什么花哨的事情。很简单。

<!DOCTYPE html>
<html lang="en">

您需要将结果附加到列表和模板中列出的渲染。

<强>演示： views.py

def get_questions(request):
    context = {}
    r = requests.get('https://api.stackexchange.com/2.2/questions?fromdate=1525737600&order=desc&sort=activity&tagged=python&site=stackoverflow').json()
    dataList = []
    for item in r['items']:
        dataList.append({'owner': item['owner']['display_name'], 'title': item['title']})
        #some other attrs here

    template = 'questions/questions_list.html'
    context['greeting'] = 'Hello'
    context['data'] = dataList

    return render(request,template,context)

<强>模板 迭代您的结果并获取所有数据

<!DOCTYPE html>
