当我将此请求发送到我的 Carrot2 服务器时：

http = httplib2.Http()
my_url = 'http://localhost:8080/dcs/rest?dcs.c2stream=xml'
xml_string = etree.tostring(xml)
http.request(my_url, 'POST', body=xml_string, headers={'Content-type': 'application/x-www-form-urlencoded'})

我得到以下回复：

{
    'status': '400', 
    'content-length': '1571', 
    'server': 'Jetty(7.3.1.v20110307)', 
    'cache-control': 'must-revalidate,no-cache,no-store', 
    'access-control-allow-origin': '*', 
    'content-type': 'text/html;charset=ISO-8859-1'
}, 
<html>\n
<head>\n
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>\n
    <title>Error 400 Could not parse Carrot2 XML stream: ParseError at [row,col]:[1,1]\nMessage: Content is not allowed in prolog.</title>\n
</head>\n
<body><h2>HTTP ERROR 400</h2>\n
    <p>Problem accessing /dcs/rest. Reason:\n
        <pre>    Could not parse Carrot2 XML stream: ParseError at [row,col]:[1,1]\nMessage: Content is not allowed in prolog.</pre></p><hr /><i><small>Powered by Jetty://</small></i><br/>\n
</body>\n
</html>\n

难道我做错了什么？我不确定要寻找什么来找到问题

编辑：我使用以下代码构建了 XML 字符串

xml = etree.Element('searchresult')
etree.SubElement(xml, 'query').text = 'dogs are fantastic pets'
for result in search_results:
    doc = etree.Element('document')
    etree.SubElement(doc, 'title').text = result['title'].replace('<b>', '').replace('</b>', '').replace('</b', '')
    etree.SubElement(doc, 'snippet').text = result['abstract'].replace('<b>', '').replace('</b>', '').replace('</b', '')
    etree.SubElement(doc, 'url').text = result['url'].replace('<b>', '').replace('</b>', '').replace('</b', '')
    xml.append(doc)
