Question

使用Angular2和dotcms，我在调用subscribe后尝试获取响应头。

HTTP/1.1 200 OK
X-Powered-By: Express
access-control-allow-origin: *
server: Apache-Coyote/1.1

好的，响应正文是空的，但在Chrome上看到我可以看到所有响应标题

ERROR TypeError: Cannot read property 'headers' of null

我有200，执行很好，我无法获得响应标题

const string serviceAccountEmail = "someemailaddresss";

var cert = new X509Certificate2(@"key.p12", "abigsecret", X509KeyStorageFlags.Exportable);

        var credential = new ServiceAccountCredential(
            new ServiceAccountCredential.Initializer(serviceAccountEmail) {
                Scopes = new[] { "https://spreadsheets.google.com/feeds" }
            }.FromCertificate(cert));

如果您想要完整响应，可以在选项对象内设置observe属性以及标题。

this.http.put(apiURL, JSON.stringify(json), 
 {observe:'response'}).subscribe((res:Response) => 
  console.log(res));

在这种情况下，您将获得整个回复以及标题。

响应为空时如何获取响应标头？
