在我的视图函数中,我将表单发送到端点,然后我收到 JSON 响应。提交表单后,响应会显示在模板上。
问题是响应中的一个键是一张以 base64url 编码的照片。例如:
{"photo": "a very long base64url"}
我想要实现的是解码 base64url 并在网页上呈现图像。
这是我的视图功能:
def post_nin(request):
if request.method == 'POST':
form = NINPostForm(request.POST)
if form.is_valid():
nin = form.cleaned_data['nin']
url = request.build_absolute_uri(reverse_lazy('nin_verification',
kwargs={'nin': nin},
))
r = requests.get(url=url)
resp = r.text
resp_json = json.loads(resp)
resp_list = resp_json['data'] # [{'tracking_id':12345, 'photo':'base64url'}]
return render(request, 'ninsuccess.html', {'response': resp_list})
else:
form = NINPostForm()
context = {'form': form, }
return render(request, 'ninform.html', context)
这是我的模板:
<table class="">
<thead>
<tr>
<th>Tracking ID</th>
<th>Picture</th>
</tr>
</thead>
<tbody>
{% for val in response %}
<tr>
<td>{{ val.tracking_id }}</td>
<td>{{ val.photo }}</td> # a long base64url is displayed which is not what I want
</tr>
{% endfor %}
