Node.js soap库创建客户端遇AxiosError: socket hang up求助

问题代码 #

const soap = require('soap');

const url = `http://xxx.xxx.1.101:8888/bmss/wd/SystemService?wsdl`

soap.createClient(url,(err:any, client:any) => {
    if (err) {
        console.error('Error creating SOAP client:', err);
        return;
    }
});

问题现象 #

调用createClient时抛出AxiosError: socket hang up错误，错误代码为ECONNRESET。

• 直接通过GET请求访问以下两个接口在Postman中均正常：
  • http://xxx.xxx.1.101:8888/bmss/wd/SystemService?wsdl
  • http://xxx.xxx.1.101:8888/bmss/wd/SystemService?wsd=1
• 使用easy-request-soap库可以正常调用服务，但希望使用soap库的client.myFunction方式开发，设置超时也无法解决问题。

排查与解决建议 #

• 检查路径拼写一致性
  从错误栈可见，soap库实际请求的路径是/bmss/ws/SystemService?xsd=1，但你提供的可用接口路径是/bmss/wd/SystemService?wsdl，注意ws和wd的差异。可能是SOAP库解析WSDL时自动生成的XSD请求路径错误，可尝试手动指定WSDL内容而非URL：

  const axios = require('axios');
  const soap = require('soap');
  
  async function createClient() {
      const wsdlContent = await axios.get('http://xxx.xxx.1.101:8888/bmss/wd/SystemService?wsdl');
      const client = await soap.createClientAsync(wsdlContent.data);
      // 后续调用client.myFunction
  }
  

• 修改HTTP客户端配置
  soap库底层使用axios，可自定义axios配置解决连接问题：

  const soap = require('soap');
  
  const url = 'http://xxx.xxx.1.101:8888/bmss/wd/SystemService?wsdl';
  const axiosConfig = {
      timeout: 30000,
      headers: {
          'Connection': 'keep-alive',
          'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36'
      },
      httpAgent: new require('http').Agent({ keepAlive: true })
  };
  
  soap.createClient(url, { axios: axiosConfig }, (err, client) => {
      if (err) {
          console.error('Error creating SOAP client:', err);
          return;
      }
      // 使用client调用服务
  });
  

• 降级或升级soap库版本
  部分版本的soap库存在axios兼容性问题，可尝试切换版本，比如降级到0.45.0或升级到最新稳定版：

  npm uninstall soap
  npm install soap@0.45.0
  

• 禁用XSD自动获取
  如果服务端不需要额外获取XSD文件，可通过配置禁用soap库的XSD解析：

  soap.createClient(url, { disableCache: true, ignoreBaseNameSpace: true }, (err, client) => {
      // ...
  });
