Question

我的响应状态为“200”，但响应为“状态响应：URL为200 OK”：对于使用Nativescript应用程序的SOAP服务调用，为null。我正在使用post方法，示例代码如下所示，

import { Injectable } from 'angular2/core';
import { Http, Request, Response, Headers, RequestMethod, RequestOptions } from 'angular2/http';
import { Observable } from 'rxjs/Observable';

@Injectable()
export class PaymentsService {

private body: string = `<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
xmlns:xsd="http://www.w3.org/2001/XMLSchema"    
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<HelloWorld xmlns="http://bernera.zapto.org/" />
</soap:Body>
</soap:Envelope>`;

private result;

constructor(private http: Http) { }

callSOAP() {

var headers = new Headers();
headers.append('Content-Type', 'text/xml');
headers.append('Access-Control-Request-Method', 'POST');
headers.append('Access-Control-Request-Headers', 'X-Custom-Header');
headers.append('Access-Control-Allow-Origin', 'http://localhost:3004');

this.http.post('http://bernera.zapto.org/astronomy/astronomy.asmx',
  this.body,
  { headers: headers })
  .subscribe(
  data => this.result = data,
  err => this.logError(err),
  () => console.log('Call complete')
  );

alert('result ' + this.result);
}

logError(err) {
console.error('There was an error: ' + err.statusText);
alert('There was an error: ' + err.statusText);
}

}

您在this.http.post(whatever_url, this.body, { headers: headers }).subscribe( data => { this.result = data; alert(this.data); // should return something }, err => this.logError(err), () => console.log('Call complete') ); alert(this.data); // <--- null, you hasn't received the server's response yet方法中放入的所有内容都是在服务器响应后异步执行的。在你的情况下，你在填充之前使用this.result。
