HTTP错误404:找不到Post请求不工作

Question

我想用邮政编码.io通过使用网站上显示的“批量查找邮政编码”从一堆邮政编码中获取经度和纬度。在

我试图将一个json对象传递给api点，正如文档中所示的那样，但是仍然得到标题中显示的错误。在

这是我的密码

allpostcodes = [i['postcode'] for i in _sortedstores()] # Getting postcodes from json file

data = {}
data['postcodes'] = allpostcodes # creating a dictionary and keeping `postcodes` and key and the postcode's as the value as shown in the example

_postcodearray = 'https://api.postcodes.io/%s' % json.dumps(data) # creating a json object and passing in the data
#_postcodearray = 'https://api.postcodes.io/%s' % data['postcodes'] #Not working



try:
    with urllib.request.urlopen(_postcodearray) as _postcodearray:
        a = _postcodearray.read()
        a = json.loads(a.decode('utf-8'))
        print(a)
except Exception as e:
    print(e)

我的数据变量在使用前的外观json.dump文件在上面{'postcodes': ['GU34 2QS', 'TN23 7DH', 'HP20 1DH']}

我也尝试过定期传递一个数组，结果却导致了同样的错误。如果您能为我的错误之处提供帮助/建议，我们将不胜感激。在
