如何将信任库文件.jks添加到SOAP nodeJs，firebase云功能中的根证书

如何解决如何将信任库文件.jks添加到SOAP nodeJs，firebase云功能中的根证书

我是网站开发的新手。我正在使用已安装SOAP npm的Firebase Cloud Functions，将SOAP请求发送到邮件服务提供商。

这是我在Firebase Cloud Functions中的原始代码：

exports.testing = functions.https.onRequest(async (request,response) =>{
  try {

    const fs = require('fs');
    const soap = require('soap');

    response.set('Access-Control-Allow-Origin','*');
    response.set('Access-Control-Allow-Credentials','true');

    const securityOptions = {
      hasNonce: true,passwordType:'PasswordDigest',hasTokenCreated:true,hasTimeStamp:false,mustUnderstand:1
    };
    const wsSecurity = new soap.WSSecurity('username','password',securityOptions);
    const bearerSecurity = new soap.BearerSecurity('token');

    const httpOptions = {
        envelopeKey: 'soap'
    };// end of httpOptions

    const url = 'https://www.serviceproviderwebsite.com/API/services/Calculator?wsdl'; // Production

    const args = {
      api01Req:{
        'userName':userName,'countryCode': areaCode,'shipCode': shipCode,'mailType': mailType,'weight': totalWeight,}
    };// end of args

    soap.createClient(url,httpOptions,function(err,client) {
      console.log("in createClient 1,err = "+err);
      client.setSecurity(bearerSecurity);
      client.setSecurity(wsSecurity);

      console.log("in createClient 2,err = "+err);
      client.getTotalPostage(args,result) {
        console.log("in getTotalPostage,err = "+err);
        console.log("in getTotalPostage,result = "+JSON.stringify(result));
          let valueUSD = parseFloat(result.getTotalPostageReturn.totalPostage)/usdValue;
          let ualueUSDRounded = math.round(valueUSD,2);
          result.getTotalPostageReturn['totalPostageUSD'] = ualueUSDRounded;
          response.status(200).send(result);
      }); // end of client.getTotalPostage
    }); // end of soap.createClient
    
  } // end of try
  catch (error) {
    console.log(error)
    response.status(500).send(error)
  } // end of catch
}); // end of exports.testing

最近我在console.log（“在createClient 1中收到错误，如下所示：err =” + err）：

错误=错误：证书链中的自签名证书

然后，我意识到我被要求向信任库中添加.jks文件，我已经在SOAP npm菜单[https://www.npmjs.com/package/soap#security][1]中呆了几天，失败。

我已将.jks文件成功上传到Firebase Cloud Functions中的文件夹。下面是结构：

-/public/
-/functions/
    - index.js
    - package.json
    - package-lock.json
    -/node_modules/
    -/certs/
        - cert.jks

有人能帮助我解决这个问题吗？非常感谢你。 [1]：https://www.npmjs.com/package/soap#security
