Creating a SOAP client with angular 2
提问by Couim
I'm looking for a way to send SOAP request to a web service, with a WSDL. Is it possible to do that with Typescript 2 and Angular 2 ?
我正在寻找一种使用 WSDL 将 SOAP 请求发送到 Web 服务的方法。是否可以使用 Typescript 2 和 Angular 2 做到这一点？
I've seen tutorials for Angular 1 but they used old angular methodes, like factoryor controller.
我看过 Angular 1 的教程，但他们使用了旧的角度方法，例如factory或controller。
I would like if it's possible, a new way to do that with TypeScript.
如果可能的话，我想要一种使用 TypeScript 做到这一点的新方法。
Any ideas ?
有任何想法吗 ？

What you need is a service that wraps around Httpand provides deserialization:
您需要的是一个环绕Http并提供反序列化的服务：
@Injectable()
export class SOAPService{
constructor(private http:Http){}
public get(url:string, options?:RequestOptionsArgs):Observable<any>{
return this.http.get(url, options).map(res => {
let xmlresult = res.text();
let result = //Here you deserialize your xml object
return result;
}
}
}
Then you can use it this way:
然后你可以这样使用它：
@Component({...})
export class ExampleComponent{
constructor(private soap:SOAPService){}
foo():{
this.soap.get('foo/bar').subscribe(...);
}
}
Since I'm not an xml parsing expert, I can't tell you how to deserialize your XML, but you can check MDNfor that, you simply have to wrap the serialization/deserialization process in another service and inject it in your SOAPService.
由于我不是 xml 解析专家，我不能告诉您如何反序列化您的 XML，但是您可以检查MDN，您只需要将序列化/反序列化过程包装在另一个服务中并将其注入您的SOAPService.

You could use a regular http-request with Angular2's [Http class] (https://angular.io/docs/ts/latest/api/http/index/Http-class.html)
This is an example from their page:
您可以将常规 http 请求与 Angular2 的 [ Http class] ( https://angular.io/docs/ts/latest/api/http/index/Http-class.html) 一起使用，这是他们页面上的一个示例：
import {Http, HTTP_PROVIDERS} from '@angular/http';
import 'rxjs/add/operator/map'
@Component({
selector: 'http-app',
viewProviders: [HTTP_PROVIDERS],
templateUrl: 'people.html'
})
class PeopleComponent {
constructor(http: Http) {
http.get('people.json')
// Call map on the response observable to get the parsed people object
.map(res => res.json())
// Subscribe to the observable to get the parsed people object and attach it to the
// component
.subscribe(people => this.people = people);
}
}
instead of asking for a json file, you could use a URL instead.
您可以使用 URL 代替请求 json 文件。
