通过angular中的ngx-soap调用soap服务时找不到方法错误

如何解决通过angular中的ngx-soap调用soap服务时找不到方法错误

我正在使用ngx-soap消耗我的soap Web服务。这段代码对于.net托管的soap服务非常有效，但是对于由Java开发并由weblogic应用程序服务器托管的其他Web服务，找不到throws方法例外。这是用于测试的简单wsdl文件内容，其中包含操作“ sayHello”，但在运行时抛出“方法sayHello未找到”异常：

如下面的浏览器控制台屏幕截图所示，客户端已成功初始化，未检测到任何操作，因此在调用方法“ sayHello”时遇到未找到的方法：

这是我使用该服务的代码块：

const promise =
      this.soap.createClient('http://ip:port/AngularserviceTest/AngularserviceTest?WSDL')
        .then(client => {
          this.client = client;
          console.log(client);
        },err => console.log(err));


    from(promise).subscribe(client => {
      return this.client.call('sayHello','')
        .subscribe(res => {
          this.xmlResponse = res.responseBody;
          this.message = res.result.AddResult;
          console.log(res.result);
      })
     });
