执行POST从Android的一个日期时间到WCF REST风格的JSON服务 [英] POSTing a DateTime from Android to a WCF RESTful JSON Service

问题描述

研究小时后，我还没有找到任何答案。 我试图发送一个DateTime作为参数传递给暴露了一个WCF RESTful服务使用JSON编码的一个方法。 请求是这样的：

after hours of research I still haven't found any answer. 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"}

我尝试了几种格式的日期时间：

I tried several formats for the DateTime:

• 2010-07-01T10：54：00
  • 在其发送的WCFTestClient应用过的net.tcp连带结果......
  • 2010-07-01T10:54:00
    • which is send by the WCFTestClient Application over net.tcp and it gets results...

    在Methoddefinition：

    The Methoddefinition:

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

    我总是以下响应：

    I always the 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}
    

    看来日期时间不正确地分析，因为有几个条目在​​日志中时间...

    It seems the DateTime isn't correctly parsed, because there are several Entries in the Log for that Time...

    有谁知道如何做到这一点？

    Does anyone know on how to do this?

    编辑：存在的问题是在服务器侧和已经解决

    The Problem was on the server side and has been resolved.

    推荐答案

    有关使用发布日期WCF服务的正确的格式： /日期（532.44亿）/ 凡在barckets的数量是毫秒自1970年以来UTC午夜数。

    The correct format for posting dates to WCF service is using : "/Date(53244000000)/" where the number in barckets 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+")/";
    

    ，然后用它作为以下

    And then use it as below

    inputparam.put("DateTime", datetime);
    

    这将工作的肯定......请，如果您有任何问题，分享。

    This will work for sure... Please share if you have any issues.
