Php 通过REST向PrestaShop添加产品时发生XML解析器错误

我试图在Python3中创建简单的GUI，以便将产品添加到商店中。 这是代码的一部分：

 def send(self):

    out = self.request('api/products?schema=blank', self.api_key.text(), 0)

    empty_xml = ET.fromstring(out)

    xml = self.InsertIntoXML(empty_xml, "test", 0)
    #xml = dump(xml)

    xml = ET.tostring(xml, encoding='utf8', method='xml')
    print(xml)
    out = self.request('products', self.api_key.text(), xml)
    print (out)
def request(self, url, key, POST):
    username = 'kluczyk'
    password = ''
    api_root = 'http://192.168.1.43/api/'

    passman = urllib.request.HTTPPasswordMgrWithDefaultRealm()
    passman.add_password(None, api_root, username, password)
    authhandler = urllib.request.HTTPBasicAuthHandler(passman)
    opener = urllib.request.build_opener(authhandler)
    urllib.request.install_opener(opener)

    if POST == 0:
        url = api_root + url
        response = urllib.request.urlopen(url).read()
    else:
        url = api_root + url
        params = urllib.parse.urlencode({'XML': POST})
        params = params.encode('utf-8')
        try:
            response = urllib.request.urlopen(url, params).read()
        except HTTPError as e:
            response = e.read()


    return response

不幸的是，我总是得到这样的答案：

它可以解析XML。为什么Prestashop不能？

如果您仍在搜索解决方案： 我认为问题在于prestashop不再以URL编码的方式获取数据。因此，只需发布xml就可以了

$xml = simplexml_load_string($_REQUEST['XML']);
var_dump($xml);[/code]
