我在Angular2 TypeScript中有这个代码,我试图添加如下所示的标题.

['access-token', localStorage.getItem( 'token' )],
['client', localStorage.getItem( 'client' )],
['uid', localStorage.getItem( 'email' )],
['withCredentials', 'true'],
['Accept', 'application/json'],
['Content-Type', 'application/json' ]

在发送请求时,我无法在请求中看到标头.我正在进行跨域设置.还有其他方法吗？

private _request(url: string | Request, options?: RequestOptionsArgs) : Observable<Response> {

    let request:any;
    let reqOpts = options || {};
    let index:any;

    if(!reqOpts.headers) {
        reqOpts.headers = new Headers();
    }

    for( index in this._config.authHeaders ) {
        reqOpts.headers.set( this._config.authHeaders[index][0], this._config.authHeaders[index][1] );
    }

    request = this.http.request(url, reqOpts);

    return request;
}

这是我的回复标题

这是html内容,我想从中选择报表中的所有元素,使用jQuery显示块 $("#report:visible")对我来说不起作用.

<div id="report">
        <div id="p1" style="display: block;">
            <input id="pname1"  type="checkbox" name="report1">
            <input id="pname2"  type="checkbox" name="report2">
        </div>
        <div id="p2"  style="display: none;">
            <input id="pname1"  type="checkbox" name="report1">
            <input id="pname2"  type="checkbox" name="report2">
        </div>
        <div id="p3"  style="display: none;">
            <input id="pname1"  type="checkbox" name="report1">
            <input id="pname2"  type="checkbox" name="report2">
        </div>
            <div id="p4"  style="display: block;">
            <input id="pname3"  type="checkbox" name="report1">
            <input id="pname4"  type="checkbox" name="report2">
        </div>
</div>

我想要一个PostgreSQL中的系列，它给出该日期之前每个星期间隔的日期

例子

1)  Date Selected is 05/31/2013
    So the series must be :
    05/31/2013 
    05/24/2013
    05/17/2013
    05/03/2013
    04/26/2013

2)  Date Selected is 05/20/2013
    So the series must be :
    05/20/2013 
    05/13/2013
    05/06/2013
    04/29/2013
    04/22/2013

我做了什么：

SELECT * 
FROM generate_series('2013-05-03 00:00'::timestamp,'2013-05-31 12:00', '1 weeks')

• 从2013-05-03开始，它提供了越来越多的系列。
• 我想从2013-05-31开始减少系列
