Question

如何在文件上传服务中添加身份验证令牌？当我登录我的应用程序时，我能够从后端检索令牌，但我很难将如何将其添加到文件服务。当我尝试上传文件时，会收到错误提示＆＃34; token_not_provided＆＃34;。由于它在我的服务中，我已在我的标题中添加了身份验证令牌，因此每当我发出请求时，服务器都会知道手头的用户。但是通过文件提交，我不知道如何将身份验证令牌附加到文件服务

 @Component({
        providers:[AuthenticationService]
    })
    @Injectable()
    export class FileUploadService {
       public progress$;
      public progressObserver;
        public progress : number;
        public token: string;
        public headers:string;


        constructor (private auth:AuthenticationService) {
            this.progress$ = Observable.create(observer => {
                this.progressObserver = observer
            }).share();
        }

         makeFileRequest (url: string, params: string[], files: File[]) {
            return Observable.create(observer => {
                let formData: FormData = new FormData(),
                    xhr: XMLHttpRequest = new XMLHttpRequest();

                for (let i = 0; i < files.length; i++) {
                    formData.append("uploads[]", files[i], files[i].name);
                }

                xhr.onreadystatechange = () => {
                    if (xhr.readyState === 4) {
                        if (xhr.status === 200) {
                            observer.next(JSON.parse(xhr.response));
                            observer.complete();
                        } else {
                            observer.error(xhr.response);
                        }
                    }
                };

                xhr.upload.onprogress = (event) => {

                    this.progress = Math.round(event.loaded / event.total * 100);

                    this.progressObserver.next(this.progress);
                };

                xhr.open('POST', url, true);
                xhr.setRequestHeader(this.headers, this.auth.token);//modified

              xhr.send(formData);


            });
        }
    }

//service
updateFood(food:any) {
        const body = JSON.stringify(food);
        const headers = new Headers({ 'Authorization': 'Bearer ' + this.authenticationService.token });
        return this.http.put('http://localhost:9000/, body, {headers: headers})
            .map((data:Response) => data.json());
    }

在def __init__(self): self.pre_client=paramiko.SSHClient() self.pre_client.set_missing_host_key_policy(paramiko.AutoAddPolicy()) sellf.pre_client.connect("server",username="user",password="password") self.client=self.pre_client.invoke_shell() def connect(self,ip): o=self.client.recv(1024) print o self.client.exec_command("telnet %s\n"%(ip)) while True: o=self.client.recv(1024) print o #EXECUTE COMMAND ON ROUTER self.client.exec_command("exit\n") if 'exit' in o: break和xhr.open之间的某处，你可以附加标题

xhr.close
