当我做团队 - >拉我的项目

我有结果失败,然后在合并输入下面我有两个修改,但没有一个影响同一个文件,所以没有冲突.

为什么这表现为失败？这是一个错误吗？

我想使用blobstore存储图像的过程以保存数据存储区中的blob键结束.所以在下面的代码中,应该在我的后端,为什么我需要一个重定向URL,因为我已经有了blob密钥？为什么我不只是将blob密钥保存在我的数据存储区中然后返回它？

public class Upload extends HttpServlet {
    private BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService();

    public void doPost(HttpServletRequest req, HttpServletResponse res)
        throws ServletException, IOException {

        Map<String, BlobKey> blobs = blobstoreService.getUploadedBlobs(req);
        BlobKey blobKey = blobs.get("myFile");

        if (blobKey == null) {
            res.sendRedirect("/");
        } else {
            res.sendRedirect("/serve?blob-key=" + blobKey.getKeyString());
        }
    }
}

此代码来自教程:https://developers.google.com/appengine/docs/java/blobstore/overview#Complete_Sample_App

我正在使用PayPal沙箱进行订阅按钮,然后当我收到订阅或订阅取消的IPN响应时,永远不会设置$ _POST ['txn_id'].

所以我不知道如何识别只接受唯一的交易

谢谢!

编辑:例如我在POST中为subscr_cancel提供的所有信息是:amount1,amount3,address_status,subscr_date,payer_id,address_street,mc_amount1,mc_amount3,charset,address_zip,first_name,reattempt,address_country_code,address_name,otify_version subscr_id custom payer_status business address_country address_city verify_sign payer_email btn_id last_name address_state receiver_email recurring txn_type item_name mc_currency residence_country test_ipn period1 period3 correlation_id

我想在 Java 中将秒数转换为 ISO_8601/Duration。

http://en.wikipedia.org/wiki/ISO_8601#Durations

是否有任何现有的内置方法可以做到这一点？

如果我做这样的事情:

<div style="margin-left: 50px;">TEST1</div>
<div style="margin-left: {{50}}px;">TEST2</div>

http://jsfiddle.net/XeVHL/1/

值test2的左边距将不会被应用,这仅在IE中,是否有任何建议可以解决这个问题？

我查看了他们的文档，他们确实提供了此功能：

但是是否可以通过 API 来做到这一点（我没有找到对此或属性的任何引用）。

我正在使用jQuery UI中的选项卡:http://jqueryui.com/demos/tabs/

我实际上在这些选项卡中有很多数据,因此当页面加载时,数据在完全处理/呈现选项卡之前完全混乱.

所以我正在寻找一种方法来检测标签何时完成渲染可能与回调函数将是我的猜测.像这样,我将能够在标签完全呈现之前显示等待消息.

谢谢 !

JSON Javascript转义

我在jsonlint上测试了我的JSON并且它是有效的,但是当我尝试解析它时出现错误,

这是我的JSON和要解析的函数:

参考 - 这个符号在 PHP 中意味着什么？

PHP 中调用 @header() 和 header() 函数有什么区别？

我想使用这个函数,但保留大写或小写,例如有类似的东西

var value = 'Replace a string';

var search = 'replace';

value.replace(search, "<span style='font-weight: bold'>"+search+'<span>');

价值的输出是:

替换一个字符串
