angular 2 中的 TSLint 错误

Question

我的代码有几个错误。我正在使用 Angular 2 + TSLint:

constructor(http: Http) {
    this.http = http;
--> let currentUser = JSON.parse(localStorage.getItem("currentUser"));
    this.token = currentUser && currentUser.token;
}

在当前用户中我有这个错误：message: 'expected variable-declaration: 'currentUser' to have a typedef；

public loginC (username: string, password: string): Observable<boolean> {
    return this.http.post( authURL + loginURL,
                     --> JSON.stringify({ password: password, username: username }))
    .map((response: Response) => {
        let token: string = response.json() && response.json().token;
        if (token) {
          this.token = token;
      --> localStorage.setItem("currentUser", JSON.stringify({token: token, username: username}));
            return true;
        } else {
            return false;
        }
    });
}

在 password: password, username: username 中：message: 'Expected property shorthand in object literal. 我真的明白这一点。最后我可以写一个简单的 model: any {};

export class LoginComponent {
--> public model: any = {};
public loading: boolean = false;
public error: string = "";
constructor (private router: Router, private authenticationService: ServerDataComponent) {
    // 
}

public login(): void {
    this.loading = true;
    this.authenticationService.loginC(this.model.username, this.model.password)
        .subscribe(result => {
           --> if (result === true) {
                this.router.navigate(["/table_per"]);
            } else {
                this.error = "Введен неверный логин и/или пароль";
                this.loading = false;
            }
        });
}

对于任何 - Type declaration of 'any' is forbidden;

Ror 结果 - expected arrow-parameter: 'result' to have a typedef

Answer 1

对于 expected variable-declaration: 'currentUser' to have a typedef，您可以为自定义类型定义 interface。

export interface User {
  token: string;
}

并用它来设置类型。

let currentUser: User = JSON.parse(localStorage.getItem("currentUser"));

对于 Expected property shorthand in object literal，当键名与变量名匹配时，您可以使用 shorthand 语法。

JSON.stringify({token, username})

对于Type declaration of 'any' is forbidden，您可以尝试将类型更改为Object。如果不是，您需要为您的模型声明另一个 interface。

public model: Object = {};

对于expected arrow-parameter: 'result' to have a typedef你需要设置参数的类型。

.subscribe((result: boolean) => {
