Question

尝试从dict渲染外来字符时出现以下错误。你知道我应该怎么做吗？

File "/base/data/home/apps/s~montaoproject/cap.354503891062679364/main.py", line 333, in render_jinja
    self.response.out.write(template.render(data))
  File "/base/data/home/apps/s~montaoproject/cap.354503891062679364/jinja2/environment.py", line 894, in render
    return self.environment.handle_exception(exc_info, True)
  File "/base/data/home/apps/s~montaoproject/cap.354503891062679364/templates/list_jinja.html", line 199, in top-level template code
    {% for key,value in location_map_br_11_cap.items() %}<option value="3" >{{ value.name }}</option>{% endfor %}
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 9: ordinal not in range(128)

这是我的变量：

location_map_br_11_cap = {1: {
    'name': str('Toda Região 11 (ddd)'),
    'lat': -23.55,
    'long': -46.64,
    'radius': 294200,
    }, 2: {
    'name': str('Todo Estado de São Paulo'),
    'lat': -22.90,
    'long': -43.21,
    'radius': 294200,
    }, 1: {
    'name': str('Toda região Sudeste do Brasil'),
    'lat': -23.55,
    'long': -46.64,
    'radius': 294200,
    }}

我会尝试这一点，希望它会成功：

location_map_br_11_cap = {1: {
    'name': str('Toda Região 11 (ddd)').decode('utf-8'),
    'lat': -23.55,
    'long': -46.64,
    'radius': 294200,
    }, 2: {
    'name': str('Todo Estado de São Paulo').decode('utf-8'),
    'lat': -22.90,
    'long': -43.21,
    'radius': 294200,
    }, 1: {
    'name': str('Toda região Sudeste do Brasil').decode('utf-8'),
    'lat': -23.55,
    'long': -46.64,
    'radius': 294200,
    }}

Answer 1

您的location_map_br_11_cap变量包含的名称是原始字符串而不是unicode字符串。将您的字符串转换为Unicode，因此Jinja知道如何在生成模板时对它们进行编码。

带有Jinja2 + GAE的UnicodeDecodeError
