XML-RPC客戶端蟒提高xml.parsers.expat.ExpatError例外

Question

我想使用的xmlrpclib蟒蛇的lib做XMP-RPC，但我越來越

xml.parsers.expat.ExpatError: XML or text declaration not at start of entity: line 1, column 1 

下面是參數的字典：

{'cliente_chave': 'hUi238sh328sjk37Hms8Kisjeg9', 
    'cliente_codigo': 164, 
    'imovel_bairro': u'Renascen\xe7a', 
    'imovel_banheiros': u'5', 
    'imovel_cidade': u'S\xe3o Lu\xeds - MA', 
    'imovel_codigo_imobiliaria': u'757', 
    'imovel_descricao': u'\n\t\t\t\n\t\t\tCasa em otima localiza\xe7\xe3o ideal tanto para empresas quanto para moradia tendo:\r\nTerra\xe7o\r\nSala Ampla para 03 ambientes\r\nLavabo\r\nHall\r\n03 su\xedtes\r\nEscritorio\r\nCozinha\r\nQuintaL\r\n\xc1rea de Servi\xe7o\r\nDCE\r\nGaragem coberta para 02 carros\r\nPort\xe3o eletronico\r\nCisterna\r\nNascente',

    'url': 'http://www.estiloma.com.br/imoveis/para-venda/em-sao-luis/no-bairro-renascenca/casa-padrao/id-774.html'} 

這裏是回溯到異常：

     self._parser.Parse(data, 0) 
    xml.parsers.expat.ExpatError: XML or text declaration not at start of entity: line 1, column 1 

我只使用UTF-8字符串

，我已經TR如果沒有運氣，可以編碼或解碼爲UTF-8。 我也嘗試谷歌它，但沒有sucsess。有人看到了嗎？

哇，這裏的客戶端代碼：

server = ServerProxy(uri=settings.RPC_SERVER, verbose=True) 
server.salvar_imovel(item) 

感謝提前的幫助。

正如我評論，ExpatError是在響應對象。由於

Answer 1

你似乎在傳遞一個dict對象的東西期待XML - 這條線

server.salvar_imovel(dict(item)) 

如果你真的必須傳中dict，你可以嘗試序列化dict第一。有一些示例代碼here。

Answer 2

[已解決]響應是在開頭用空格發送的。 我不得不從xmlrpc擴展Transport類，並簡單地刪除響應。

class CustomTransport(Transport): 
    def parse_response(self, response): 
     # read response data from httpresponse, and parse it 

     # Check for new http response object, else it is a file object 
     if hasattr(response,'getheader'): 
      if response.getheader("Content-Encoding", "") == "gzip": 
       stream = GzipDecodedResponse(response) 
      else: 
       stream = response 
     else: 
      stream = response 

     p, u = self.getparser() 

     while 1: 
      data = stream.read(1024) 
      data = data.strip() 
      if not data: 
       break 
      if self.verbose: 
       print "body:", repr(data) 
      p.feed(data) 

     if stream is not response: 
      stream.close() 
     p.close() 

     return u.close()
