从Android发布DateTime到WCF RESTful JSON服务 [英] POSTing a DateTime from Android to a WCF RESTful JSON Service

问题描述

我正在尝试将一个 DateTime 作为参数发送到通过使用JSON编码的WCF RESTful服务公开的方法。请求如下所示：

I'm trying to send a DateTime as a parameter to a method exposed over a WCF RESTful service with JSON encoding. The request looks like this:

POST http://IP:PORT/LogService/json/GetLogEntriesByModule HTTP/1.1
Content-Length: 100
Content-Type: application/json
Host: IP:PORT
Connection: Keep-Alive
User-Agent: Apache-HttpClient/UNAVAILABLE (java 1.4)
Expect: 100-Continue

{"maxentries":10,"upperdate":"1280703601462","lowerdate":"1277938801462","module":"Windows Service"}

< ：

I tried several formats for the DateTime:

• 2010-07-01T10：54：00 （由...发送通过NET.TCP的 WCFTestClient 应用程序，并获得结果


• \ / Date（12345678 + 0100） \ /


• 01.07.2010 10:54:00

• 2010-07-01T10:54:00 (which is send by the WCFTestClient application over NET.TCP and it gets results
• \/Date(12345678+0100)\/
• 01.07.2010 10:54:00

方法定义：

LogEntry[] GetLogEntriesByModule(
    string module,
    DateTime lowerDate,
    DateTime upperDate,
    int maxEntries,
    out bool maxEntriesReached
)

我总是得到以下回复： p>

I always get the following response:

HTTP/1.1 200 OK
Content-Length: 60
Content-Type: application/json; charset=utf-8
Server: Microsoft-HTTPAPI/2.0
Date: Fri, 02 Jul 2010 09:07:04 GMT

{"GetLogEntriesByModuleResult":[],"maxEntriesReached":false}

似乎 DateTime 没有正确解析，因为当时的Llog中有几个条目。

It seems the DateTime isn't correctly parsed, because there are several entries in the Llog for that time.

有谁知道如何做到这一点？

Does anyone know on how to do this?

更新：问题出在服务器端，已解决。

Update: The problem was on the server side and has been resolved.

推荐答案

发布日期到WCF服务的正确格式是：
/ Date（53244000000）/
其中括号中的数字是自1970年UTC午夜以来的毫秒数。

The correct format for posting dates to WCF service is using: /Date(53244000000)/ where the number in brackets is the number of milliseconds since 1970 UTC Midnight.

Date dt = new Date();
long date = Date.UTC(dt.getYear(), dt.getMonth(), dt.getDay(), dt.getHours(),dt.getMinutes(), dt.getSeconds());
String senddate = "/date("+date+")/";

然后使用它如下

inputparam.put("DateTime", datetime);
