解析JSON Github API Django

Question

我在我的views.py中有这个：

def profile(request):
    parsedData = []
    if request.method == 'POST':
        username = request.POST.get('user')
        req = requests.get('https://api.github.com/users/' + username + '/repos') 
        jsonList = []
        jsonList.append(req.json())
        userData = {}
        data = ['owner']
        for data in jsonList:
            userData['html_url'] = data['owner'][0]['html_url']
            userData['created_at'] = data['created_at']
            userData['updated_at'] = data['updated_at']
            userData['forks_count'] = data['forks_count']
        parsedData.append(userData)
    return render(request, 'app/profile.html', {'data': parsedData})

这让我想到：

这是Github上/repos返回的JSON示例：

我试过很多方法，但是错误仍然存在，有什么想法吗？在

编辑

错误出现在这一行userData['html_url'] = data['owner'][0]['html_url']，但在其他行，这只是我尝试的两种方法的一个例子。错误仍然存在。在

Answer 1

data = ['owner']表示data是一个包含一个字符串的列表owner，但并不意味着它是一个包含一个键的字典owner（正确的应该是data={"owner": None}）。在

所以当你像data["owner"]那样访问它时，你试图像字典一样使用它，但它是一个列表。在

这就是为什么会出现错误：list indices must be integers, not str。在

Answer 2

github的响应已经是一个列表，因此jsonList中的第一个元素是一个列表，这就是发生异常的原因。在

更改为：

jsonList=req.json()

它应该会起作用的

Answer 3

问题是，您将响应附加到一个列表中。 那么响应只包含一个JSON对象。在

因此，你甚至不必循环它。直接赋值就行了。在

data = req.json()
userData = {}
# Copy values right away
userData['html_url']    = data['owner'][0]['html_url']
userData['created_at']  = data['created_at']
userData['updated_at']  = data['updated_at']
userData['forks_count'] = data['forks_count']

然后在您的响应中，如果客户机不需要列表，则无需将userData附加到列表类型。直接传递为：
