angular - Angular NGX-SOAP 请求获取 ERR_RESPONSE_HEADERS_TRUNCATED

Question

我目前在本地主机中，并试图向外部公共 SOAP 服务发出肥皂请求。我能够使用 Soap 客户端在 PHP localhost 上发出请求。但是现在我在提出请求时遇到了 Angular 问题。让我介绍一下我的代码。

首先是 WSDL 的在线版本 => HERE

模块的构造函数没有错误：

  constructor(private soap: NgxSoapService, private httpClient: HttpClient, private snackBar: MatSnackBar, public dialog: MatDialog, private auth: AuthenticationService, private restApi: RestApi) {
    let headers = new HttpHeaders({
      'Content-Type': 'text/xml',
      'Access-Control-Allow-Headers': 'origin, content-type, accept, authorization',
      'Access-Control-Allow-Origin': '*',
      'Access-Control-Allow-Credentials': 'true',
      'Access-Control-Allow-Methods': 'GET, POST',
    });
    this.soap.createClient('./assets/wsdl/CityService.wsdl', {headers: headers}).then(client => {
      this.client = client;
    })
      .catch(function(error) {
        console.log(error);
      });
  }

这是一个基本的 SOAP 请求函数。

  makeAnExampleRequest() {
    this.client.call('GetCities', {}).subscribe((res: ISoapMethodResponse) => console.log(res), (error) => console.error(error));
  }

调用上述函数时，出现以下错误：

从控制台.错误（错误）：

来自 zone-evergreen.js：

POST https://api.n11.com/ws/cityService/ net::ERR_RESPONSE_HEADERS_TRUNCATED

我用另一个需要身份验证对象的请求尝试了另一个 WSDL，我得到的只是同样的错误
