小编Eld*_*dar的帖子

第一个块按预期工作

getQuotes(): Observable<Quote[]> {
    return this.http.get(this.url)
        .map((res: Response) => res.json())
        .catch((error: any) => Observable.throw(error.json().error || 'Server error'));
}

现在我要向this.url添加查询参数,并且url没有改变

getQuotes2(): Observable<Quote[]> {
    let myParams  = new URLSearchParams();
    myParams.append('author', 'authorName');
    myParams.append('catid', '123');
    let options = new RequestOptions({ params: myParams });

    return this.http.get(this.url, options )
        .map((res: Response) => res.json())
        .catch((error: any) => Observable.throw(error.json().error || 'Server error'));
}

我检查过devtools.缓存已关闭.我尝试{search:myParams},使用RequestOptions并返回this.http.get(this.url,{params:myParams})我不看的地方我看到字符串连接.这些参数是optinal,我将它们附加在条件上.

再会，

我使用 paged.js 在每个页面上添加了顶部标题，但这种方法不适用于页脚。我考虑过缺少分号。

@page {
  @top-center {
    content: element(repeatable);
  }
  
  @bottom-center {
    content: element(footerblock);
  }
  
  border: 1px solid black;
}

.repeatable {
  display: block;
  position: running(repeatable);
}

.footerblock {
  display: block;
  position: running(footerblock);
}

.page1,
.page2,
.page3 {
  break-before: page;
}

  <div class="page1">page 1 content</div>
