从 Angular 5.2 升级到 7 破坏了 Post 方法

Question

'(error: HttpErrorResponse) => void' 类型的参数不是 可分配给类型参数'（错误：任何，捕获： 可观察>) => 可观察输入'。类型 'void' 不可分配给类型 'ObservableInput'

GetFullAddress(addressModel: FullAddressLookupModel): Observable<AddressModel> {
    return this.httpClient.post<AddressModel>(this.Domain + "api/addressSearch/confirmAddressSelection",
        JSON.stringify(addressModel), this.httpOptions ).pipe(
            catchError(this.handleError)
        );
}



private handleError(error: HttpErrorResponse) {
    return throwError(
        'Something bad happened; please try again later.');
}

Answer 1

请试试这个：

public GetFullAddress(addressModel: FullAddressLookupModel): Promise<AddressModel> {
    const promise: Promise<AddressModel> = new Promise<AddressModel>((resolve, reject) => {
        this.httpClient.post<AddressModel>(`${this.Domain}api/addressSearch/confirmAddressSelection`, JSON.stringify(addressModel), this.httpOptions ).pipe(
            catchError(this.handleError)
        )).toPromise().then((response) => {
            resolve(response);
        }, (err) => {
            reject(err);
        });
    });

    return promise;
}

出现以下错误
