MaxCompute:Mengakses layanan HTTPS melalui alamat IP

1. Dapatkan alamat IP layanan remote.

ping service.cn-shanghai-vpc.maxcompute.aliyun-inc.com

2. Konfigurasikan client HTTP.

Contoh kode berikut menunjukkan cara membuat adapter HTTP kustom untuk versi Python yang berbeda. Adapter ini mengirim alamat IP dalam URL permintaan tetapi menggunakan nama domain asli dalam Header Host untuk validasi SSL. Sebelum menerbitkan tugas Anda, uji akses remote dari lingkungan jaringan yang sesuai.

  class HostHeaderSSLAdapter(requests.adapters.HTTPAdapter):

          self.resolved_ip = resolved_ip
      def send(self, request, **kwargs):
          connection_pool_kwargs = self.poolmanager.connection_pool_kw
          result = urlparse(request.url)
          if result.scheme == 'https' and self.resolved_ip:
              request.url = request.url.replace(
                  'https://' + result.hostname,
