我有一个使用webapi加载/保存数据的网络应用程序
所有以前工作好/
今天我发现有一个更新到ASP.NET MVC / webapi,我安装了更新
但是之后,使用 jquery发送数据不再有效.
我在客户端代码或webapi控制器中没有做任何改变.

我的典型POSt语句如下所示：
showProgress(true,self.PanelID(),'Saving...')
j$.ajax({
type: "POST",url: uri,data: dataObj,error: function (jqXHR,status,error) {
showProgress(false);
GLOBAL.setMessage(self,'Error saving ' + opType + '<br>' + error,true);
},success: function (data,jqXHR) {
showProgress(false);
if (status === 'success') {
GLOBAL.setMessage(self,opType + " saved ok");
//....
"An error has occurred."
ExceptionMessage
"This method or property is not supported after HttpRequest.Form,Files,InputStream,or BinaryRead has been invoked."
ExceptionType
"System.Web.HttpException"

这些是我的解决方案中的nuget包
package id="Microsoft.AspNet.Mvc" version="5.1.0" targetFramework="net45" package id="Microsoft.AspNet.Razor" version="3.1.0" targetFramework="net45" package id="Microsoft.AspNet.SignalR.Client" version="2.0.1" targetFramework="net45" package id="Microsoft.AspNet.Web.Optimization" version="1.1.2" targetFramework="net45" package id="Microsoft.AspNet.WebApi" version="5.1.0" targetFramework="net45" package id="Microsoft.AspNet.WebApi.Client" version="5.1.0" targetFramework="net45" package id="Microsoft.AspNet.WebApi.Core" version="5.1.0" targetFramework="net45" package id="Microsoft.AspNet.WebApi.HelpPage.VB" version="5.1.0" targetFramework="net45" package id="Microsoft.AspNet.WebApi.OData" version="5.1.0" targetFramework="net45" package id="Microsoft.AspNet.WebApi.WebHost" version="5.1.0" targetFramework="net45" package id="Microsoft.AspNet.WebPages" version="3.1.0" targetFramework="net45" package id="Microsoft.Bcl" version="1.1.6" targetFramework="net45" package id="Microsoft.Bcl.Build" version="1.0.13" targetFramework="net45" package id="Microsoft.Data.Edm" version="5.6.0" targetFramework="net45" package id="Microsoft.Data.OData" version="5.6.0" targetFramework="net45" package id="Microsoft.Net.Http" version="2.2.18" targetFramework="net45" package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net45"
有人知道有什么问题吗？任何想法如何解决？
编辑
样品控制器代码：
Public Class ImportController
Inherits ApiController
Public Function SaveImportSession(sessid As string,entity As SIImportSessionDTO) As HttpResponseMessage
Try
InspectionData.SaveImportSession(sessid,entity)
Dim response = Request.CreateResponse(HttpStatusCode.Accepted)
Return response
Catch ex As HttpResponseException
Throw
Catch ex As Exception
Throw New HttpResponseException(Request.CreateResponse(Of String)(HttpStatusCode.InternalServerError,ex.Message))
End Try
End Function
我只使用基于属性的路由,这是我的webapi路由配置
Public Shared Sub Register(ByVal config As HttpConfiguration)
config.MapHttpAttributeRoutes()
config.Routes.MapHttpRoute( _
name:="DefaultApi",_
routeTemplate:="api/{controller}/{id}",_
defaults:=New With {.id = RouteParameter.Optional} _
问题,我的服务器端代码甚至没有达到,管道上的其他东西都抛出异常
谢谢
解决方法
我发现问题.
我的邮政编码使用$.ajax(…),如初始消息中所示.
但是jquery的.ajax post数据应用程序/ x-www-form-urlencoded.
这在以前的WebAPI版本中起作用,但是在最新的更新中,它似乎默认不接受application / x-www-form-urlencoded.
我将内容类型更改为application / json,我不得不将数据转换为json,这样可以解决问题.
所以,而不是
j$.ajax({
type: "POST",success: function(...)
我不得不改变
j$.ajax({
type: "POST",data: JSON.stringify(dataObj),contentType: "application/json; charset=utf-8",success: function(...)
