Large file upload when using ssl and client certificates (uploadReadAheadSize) but dont want all data to be readahead

由 一世执手 提交于 2019-12-09 17:37:03
问题 I tried to search the internet/stack overflow and couldn't find any relevant answer that worked for me. I have an asp.net web api2 application (uses ssl only). I'm trying to allow large file upload (up to ~36mb) but unless i change uploadReadAheadSize to readahead this size I get an error from IIS that the request is too long. I don't want to set that attribute because then my data stream only arrives after IIS read it all already. My question is: How can I do large file upload with asp.net

由 不问归期 提交于 2019-12-09 14:42:41
问题 I am disgusted not have found a solution to this problem. I started creating a new api using Web API 2 and just cannot get the POST and PUT to work. The Get all and Get single item works perfectly fine. There are no related articles anywhere, and those that i've found relates only to Gets and Web API, but not Web API 2. Any assistance would do please. // POST: api/checkOuts [HttpPost] [ResponseType(typeof(checkOut))] [ApiExplorerSettings(IgnoreApi = true)] public async Task<IHttpActionResult>

Convert File to byte array Angular 2

由 旧时模样 提交于 2019-12-09 13:57:59
问题 How can I convert input file(image,for example) to byte array by using Angular2 ? Maybe someone can say what is better: convert image to byte array and send it to Web API or send the File "object" to API and there convert it? 回答1: You wouldn't really use Angular for solving this task. JavaScript has APIs for handling File data, e.g. https://developer.mozilla.org/en-US/docs/Web/API/FileReader/readAsArrayBuffer See this question PS: "Angular 2" is just called "Angular" now, because they're on

由 Deadly 提交于 2019-12-09 10:51:05
问题 Problem: I need to handle web api 2 exceptions and return a rich object with the correct status code (401 for Unauthorized, 404 for ContentNotFound, etc) and some extra information as the content.

Return an object along with a 409 Conflict error in a Web API 2 POST call backed by Entity Framework?

问题 I have a C# Entity Framework Web API 2 controller . Currently when an attempt is made via the POST method to create an object with the same text for the main text field, I return a 409 Conflict error as an StatusCode result to indicate the addition is considered a duplicate. What I'd like to do is return the server side object that triggered the duplicate error too. So I need something akin to the Ok() method but a variant that returns a 409 Conflict error as the HTTP status code instead of

由 谁都会走 提交于 2019-12-09 05:59:45

Exception in HttpControllerDispatcher

由 谁说胖子不能爱 提交于 2019-12-08 23:04:37
