Question

有两个WP_Post Object ( [ID] => 778 [post_author] => 1 [post_date] => 2018-12-06 09:18:26 [post_date_gmt] => 2018-12-06 09:18:26 [post_content] => This is Solomon [post_title] => Solomon Northup [post_excerpt] => [post_status] => publish [comment_status] => closed [ping_status] => closed [post_password] => [post_name] => solomon-northup [to_ping] => [pinged] => [post_modified] => 2018-12-06 09:18:26 [post_modified_gmt] => 2018-12-06 09:18:26 [post_content_filtered] => [post_parent] => 0 [guid] => http://localhost:8888/swart.shop/wp/?post_type=artists&p=778 [menu_order] => 0 [post_type] => artists [post_mime_type] => [comment_count] => 0 [filter] => raw )：Angular 6 Components和DetailsProduct。当我编辑产品时，我将被重定向到有关该产品的详细信息页面。我的问题是，当我返回到“详细信息”时，已保存的新数据没有显示，而旧数据却显示了。这是EditProduct的代码：

EditProduct

这是EditProduct() { let url = this.baseUrl + `/products/${this.id}`; this.httpClient.put(url, JSON.stringify(query), httpOptions).subscribe( response => {console.log(response); this.successMessage = true;}, err => { console.log(err); this.errorMessage = true;} ); this.goToDetails(); } goToDetails() { this.router.navigate(['details-product/'+this.id]); }的代码：

DetailsProduct

这是我在路由模块中所拥有的：

getProductDetails() {
    let url = this.baseUrl + `/products/${this.id}`
    this.httpClient.get(url)
        .subscribe(data => { this.oneProduct= data; })
}

任何想法在重定向到详细信息后如何获取新的保存数据（获取更新的数据）？在其他主题中找不到适合我的东西...

我遇到了这个topic about Resolver，但无法正确解决。任何帮助都非常感谢。

我使用了解析器，但未做任何更改。

解决方案是：

EditProduct() {

    let url = this.baseUrl + `/products/${this.id}`;
    this.httpClient.put(url, JSON.stringify(query), httpOptions).subscribe(
        response => {
              this.goToDetails();
              console.log(response); this.successMessage = true;},
        err => { console.log(err);  this.errorMessage = true;}
    );

}

它在subscribe内部调用重定向方法。很简单。

修改后获取更新的数据并重定向到另一条路线
