我现在用的是HttpPut与Android的服务器进行通信,响应code我正为500.After先生与服务器的家伙,他说:prepare字符串中包含并发送。
I am using the HttpPut to communicate with server in Android, the response code I am getting is 500.After talking with the server guy he said prepare the string like below and send.
{关键:值,重点:值}
{"key":"value","key":"value"}
现在我完全糊涂了我应该在哪里添加此字符串中的我的要求。
now I am completely confused that where should i add this string in my request.
请帮我了。

我最近不得不想出一个办法让我的Android应用程序与WCF服务进行通信,并更新特定的记录。起初,这真的让我很难计算出来,主要是因为我不知道有足够的了解 HTTP
的协议,但我能够创建一个 PUT
使用以下内容:
I recently had to figure out a way to get my android app to communicate with a WCF service and update a particular record. At first this was really giving me a hard time figuring it out, mainly due to me not knowing enough about HTTP
protocols, but I was able to create a PUT
by using the following:
URL url = new URL("http://(...your service...).svc/(...your table name...)(...ID of record trying to update...)");
//--This code works for updating a record from the feed--
HttpPut httpPut = new HttpPut(url.toString());
JSONStringer json = new JSONStringer()
.object()
.key("your tables column name...").value("...updated value...")
.endObject();
StringEntity entity = new StringEntity(json.toString());
entity.setContentType("application/json;charset=UTF-8");//text/plain;charset=UTF-8
entity.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json;charset=UTF-8"));
httpPut.setEntity(entity);
// Send request to WCF service
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpResponse response = httpClient.execute(httpPut);
HttpEntity entity1 = response.getEntity();
if(entity1 != null&&(response.getStatusLine().getStatusCode()==201||response.getStatusLine().getStatusCode()==200))
{
//--just so that you can view the response, this is optional--
int sc = response.getStatusLine().getStatusCode();
String sl = response.getStatusLine().getReasonPhrase();
}
else
{
int sc = response.getStatusLine().getStatusCode();
String sl = response.getStatusLine().getReasonPhrase();
}
通过这就是说有通过使用一个库,将生成的更新方法为你让你更新的记录,而无需手动编写code像我上面更容易的选择。 2.库,似乎是常见的有 odata4j
和的Restlet
。虽然我一直没能找到一个明确的容易教程 odata4j
有一对的Restlet
这是非常好的:http://weblogs.asp.net/uruit/archive/2011/09/13/accessing-odata-from-android-using-restlet.aspx?CommentPosted=true#commentmessage
With this being said there is an easier option by using a library that will generate the update methods for you to allow for you to update a record without having to manually write the code like I did above. The 2 libraries that seem to be common are odata4j
and restlet
. Although I haven't been able to find a clear easy tutorial for odata4j
there is one for restlet
that is really nice: http://weblogs.asp.net/uruit/archive/2011/09/13/accessing-odata-from-android-using-restlet.aspx?CommentPosted=true#commentmessage
