ajax请求不适用于mvc4中的最大查询字符串 [英] ajax request not working for max query string in mvc4

问题描述

嗨团队，



我的json ajax请求无法处理mvc 4代码中的最大查询字符串。

我的网址没有打到控制器jsonresult动作。

当我发送小号没有。查询字符串然后它的工作。

你能不能帮我解释它为什么不起作用。



以下是我的代码。

Hi team,

My json ajax request not working on max query string in mvc 4 code.
my url not hit the controller jsonresult action.
when i send small no . of query string then its working.
Can you any body help me why its not working.

Below is my code.

strSelecteds = strSelecteds.substring(0, strSelecteds.length - 1);
$.ajax({
    url: "/Usermanagement/AddProxyGroupMapping?jsonValue=" + strSelecteds + '&IsInsert=' + IsInsert + '&PackageId=' + packegeId + '&Allocate=' + Allocate,
    type: 'POST',
    contentType: 'application/json;charset=utf-8'
});

strSelecteds字符串的最大记录长度超过1000。

我在webconfig文件中使用下面的代码，但它不起作用。

The strSelecteds string have the max record with more the 1000 length.
I am using below code in webconfig file but its not working .

<system.web.extensions>
  <scripting>
    <webServices>
      <!-- Try increasing this value to a larger value (Int.MaxValue used below) -->
      <jsonSerialization maxJsonLength="2147483644"></jsonSerialization>
    </webServices>
  </scripting>
</system.web.extensions>

我想知道，如何通过mvc4中的ajax请求处理最大记录

类型：' POST'，
contentType：' application / json; charset = utf-8'

.ajax({ url: "/Usermanagement/AddProxyGroupMapping?jsonValue=" + strSelecteds + '&IsInsert=' + IsInsert + '&PackageId=' + packegeId + '&Allocate=' + Allocate, type: 'POST', contentType: 'application/json;charset=utf-8' });

由于您要发布，请不要像使用GET一样发送数据。设置固定路径

/ Usermanagement / AdProxyGroupMapping然后使用

data：发送你需要的东西



像这样：

Since you're posting, do not send the data as if you're using GET. Set the fixed path
/Usermanagement/AdProxyGroupMapping and then use
"data: " to send what you need

like this:

strSelecteds = strSelecteds.substring(0, strSelecteds.length - 1);

.ajax（{
url： / Usermanagement / AddProxyGroupMapping，
type：' POST'，
data：{' jsonValue'：strSelecteds，< span class =code-string>' IsInsert'：IsInsert，' PackageId'：packageId，' 分配'：分配}
contentType：' application / json; charset = utf-8'
}）;

.ajax({ url: "/Usermanagement/AddProxyGroupMapping", type: 'POST', data: {'jsonValue': strSelecteds, 'IsInsert': IsInsert, 'PackageId': packageId, 'Allocate': Allocate } contentType: 'application/json;charset=utf-8' });

您可能需要调整一下，数据需要是JSON，也许我拼错了一些东西，但是发送长查询字符串（IE中限制为大约2000个字符，总共4000个字符）不是很好想法。



由于您使用的是POST方法，请将数据发送至帖子。





如果这有帮助，请花时间接受解决方案。谢谢。

You might need to tweak this, data needs to be JSON, maybe I misspelled something, but sending long query string (which is limited to around 2000 characters in IE and 4000 total) is not a good idea.

Since you are using POST method, send the data as for post.


If this helps please take time to accept the solution. Thank you.
