Here Mudassar Ahmed Khan has explained how to upload and insert XML file data using Stored Procedure in ASP.Net using C# and VB.Net. SQL Server 2005 onwards we can.
That is the reason why its failing. Consider granting access rights to the resource to the ASP. NET request identity. Right click on downloading folder Properties > Security Tab > Edit > Add > locations > choose your local machine > click OK > Type ASPNET below . If it will not work for you do the same with Network Service.
Now this should show your local . Or just use dedicated location for storing files in ASP. NET which is App. To create it right click on your ASP. NET Project (in Visual Studio) Add > Add ASP.
NET Folder > App. Then you'll be able to save data to this location: var path = Server.
No-registration upload of files up to 250MB. Not available in some countries. Updated : Upload Files in ASP.NET Core 1.0 (Form POST and jQuery Ajax) Uploading files is a common requirement in web applications. In ASP.NET Core 1.0 uploading. Here's an issue with IIS 7.5 and ASP.NET that I've been researching and getting nowhere with. Any help would be greatly appreciated. My question is: using ASP.NET in.

Token Based Authentication Using ASP. Net Web API, OWIN and Identity With Entity Framework. Introduction. The Open Web Interface for .
NET (OWIN) defines a standard interface between . NET web servers and web applications.
Katana is open- source components for building and hosting OWIN- based web applications. It provides the implementation of the OWIN specification. The OAuth authorization framework enables a third- party application to obtain limited access to a HTTP service. Currently the preferred approach to authenticate the users is to use a signed token and this token is sent to the server with each request.
The following are the benefits for using this approach. Scalability of Serversthe token itself contains all the information of the user that is needed for authentication, so Web Farm extension is an easy task. There is no dependence on shared session stores. Loosely Coupling. Our front- end application is not coupled with a specific authentication mechanism. The token is generated from the server and our web API has a built- in way to understand this token and perform authentication. Mobile Friendly. This type of authentication does not require cookies, so this authentication type can be used with mobile applications.
Example. In the following demo application, the OAuth authorization server and the Web API endpoints will be hosted inside the same host. The following is the procedure to do Token Based Authentication using ASP. NET Web API, OWIN and Identity. Step 1. Create and configure a Web API project. Create an empty solution for the project template .
It also downloads some other dependency packages. One of those dependency packages is . This is a core package required to support any standard OAuth 2. The “Microsoft. Owin.
Host. System. Web” namespace contains the types related to handling OWIN requests. It helps us to run OWIN- based applications on IIS using the ASP. NET request pipeline. Use the following commands to instal the OWIN server. PM> Install- Package Microsoft.
Asp. Net. Identity. Owin. PM> Install- Package Microsoft. Owin. Host. System. Web. ASP. NET Identity also supports the Entity Framework. Here we will use ASP.
Net identity with Entity Framework, so we need to install this via Nuget packages. PM> Install- Package Microsoft.
Asp. Net. Identity. Entity. Framework. This will also install the Entity Framework as a dependency. Step 3. Create a Db. Context class. The Identity. Db. Context Class uses the default entity types for ASP.
NET Identity Users, Roles, Claims and Logins. We can overload this to add our own entity types. Owin. Auth. Db. Context : Identity. Db. Context . Migration commands can be executed from the Package Manager Console. Step 4. Define an OWIN Startup Class. Every OWIN application has a startup class in which we specify components for the application pipeline.
Here we are using the Owin. Startup Attribute to connect to the startup class with the hosting runtime.
Microsoft. Owin; using Owin; . Later on we can retrieve it using the context. Get method. This method creates one instance of the given type per request. Here we are using ASP. Net Identity with Entity Framework, so we must create the instance of our Db. Context class and to do this we use this extension method. The Microsoft. Asp.
Net. Identity namespace has the class User. Manager that exposes the use related to the API that automatically saves the changes to the User. Store. Here we will interact with our database using the User. Manager class. The following code is required to use the User. Manager class inside our OWIN component efficiently. Configure. OAuth(IApp. Builder app) . Following are the setup options.
Token. Endpoint. Pathrequests the path on which the client application directly communicates to obtain the access token. It must begin with a leading slash, for example . It must begin with a leading slash (the same as Token.
Endpoint. Path). Allow. Insecure. Http. Set to true to allow authorize and token requests to arrive on HTTP URI addresses.
Providerthe object provided by the application to process events raised by the Authorization Server. It may the instance of OAuth. Authorization. Server. Provider and assign delegates necessary for the OAuth flow. Authorization. Code.
Providerproduces a single- use authorization code to return to the client application. It is required where the token is produced by the On. Create/On. Create.
Async event. Refresh. Token. Providerproduces a refresh token that may produce a new access token when required.
If this option is not provided then the authorization server will not return refresh tokens from the Token endpoint. Application. Can. Display. Errors. Set to true when the web application is able to render error messages on the Authorize endpoint. This is required only in cases where the browser is not redirected back to the client application.
Access. Token. Expire. Time. Span. The time period the access token remains valid after it was generated. The default value is 2. Access. Token. Format. The data format used to protect the information contained by the access token.
If it is not provided then the application will use the default data protection provider depending on the host server. Access. Token. Provider.
It produces a bearer token. Authorization. Code.
Expire. Time. Span. The time period the authorization code remains valid after it was generated. The default value is 5 minutes. Authorization. Code. Format. The data format used to protect and unprotect the information contained in the authorization code.
Refresh. Token. Format. The data format used to protect and unprotect the information contained in the refresh token. System. Clock. Used to know what the current clock time is when calculating or validating token expiration. The default value is Date. Time. Offset. Utc.
Now. OAuth. Authorization. Server. Provider provides some default behavior like as used as a virtual base class and offers delegate properties that may be used to handle individual calls without creating the instance. Here I just override the methods that I need here: Validate. Client. Authentication and Grant. Resource. Owner. Credentials.
Validate. Client. Authentication. It is called to validate that the requester (origin of the request) is a registered client. If the web application accepts a client id and secret as form- encoded POST parameters, . Finally, if . This occurs when the user provides a user id and password directly to the client application using the client application user interface.
If the web application supports the resource owner credentials grant type, it must validate the username and password property of context. To issue the access token, the request must end with the “OAuth. Grant. Resource. Owner. Download Game Jacked Full Crack Pc on this page. Credentials. Context. Validated. The default behavior is to reject this grant type.
Authorization. Server. Provider : OAuth. Authorization. Server. Provider . In this place we can retrieve the client credentials and validate it. If the client credential is invalid, we need to return an unauthorized request using the context. Rejected method. If we grant the request in the Validate.
Client. Authentication method, the request will arrive at the Grant. Resource. Owner. Credentials method. Inside this method, we need to validate that the user is using resource- owner credentials.
Step 6. Test the Project. To test the preceding approach I created a console project in my solution. Create the following Token class within the console application. Newtonsoft. Json; namespace OWINTest . Here I have encrypted my password using Abstraction for the password hashing methods of the Microsoft.
Asp. Net. Identity namespace available with the User. Manger class. INSERT .
The Result Token class contains either the access token or an error. If we pass the wrong credentials, the system will generate the error: In the next request we use this token for the authentication and the token will be sent in the request header. The Token is valid up to its expiry time. To test it, I added a controller to my Web API project and created a test method as in the following.
System. Web. Http; namespace Owin. Authentication. Controllers . The following is needed to append in a client application (console application in our case). First of all we need to get the token using the code described in the preceding section and then use this token to process the request. Http. Client http.
Client. 1 = new Http.
