Root Cause

The SOAP client failed to receive HTTP response headers from the remote server, often due to network timeout, proxy misconfiguration, or the server closing the connection prematurely.

generic

中文

SOAP 客户端未能从远程服务器接收到 HTTP 响应头，通常是由于网络超时、代理配置错误或服务器提前关闭连接。

Workarounds

  1. 80% success Increase the SOAP client timeout by setting 'connection_timeout' and 'default_socket_timeout' in the stream context: `$context = stream_context_create(['http' => ['timeout' => 30]]); $client = new SoapClient($wsdl, ['stream_context' => $context]);` 
    Increase the SOAP client timeout by setting 'connection_timeout' and 'default_socket_timeout' in the stream context: `$context = stream_context_create(['http' => ['timeout' => 30]]); $client = new SoapClient($wsdl, ['stream_context' => $context]);`
  2. 85% success Configure a proxy in the SOAP client options if behind a corporate firewall: `$client = new SoapClient($wsdl, ['proxy_host' => 'proxy.example.com', 'proxy_port' => 8080]);` 
    Configure a proxy in the SOAP client options if behind a corporate firewall: `$client = new SoapClient($wsdl, ['proxy_host' => 'proxy.example.com', 'proxy_port' => 8080]);`
  3. 70% success Use `file_get_contents()` with a stream context to test basic connectivity to the SOAP endpoint before initializing the client; log the response headers for debugging.

中文步骤

  1. 通过在流上下文中设置 'connection_timeout' 和 'default_socket_timeout' 来增加 SOAP 客户端超时：`$context = stream_context_create(['http' => ['timeout' => 30]]); $client = new SoapClient($wsdl, ['stream_context' => $context]);`
  2. 如果在公司防火墙后，在 SOAP 客户端选项中配置代理：`$client = new SoapClient($wsdl, ['proxy_host' => 'proxy.example.com', 'proxy_port' => 8080]);`
  3. 在初始化客户端之前，使用带流上下文的 `file_get_contents()` 测试与 SOAP 端点的基本连接；记录响应头以进行调试。

Dead Ends

Common approaches that don't work:

  1. 85% fail

    The SOAP client uses its own timeout settings (default_socket_timeout) which are independent of max_execution_time.

  2. 75% fail

    The error occurs during the actual SOAP call, not during WSDL loading.

  3. 90% fail

    The extension is functional; the issue is external network connectivity.
