How to download file in Angular 6 using www.tumblr.com Core web API – DOTNET DETAIL
To see how to add a bearer token to all http requests in Angular see one of my previous articles: Angular 5 HttpInterceptor – Add Bearer Token to HttpClient Requests. In this article I will use a zip file as an example. Download file as Blob. First of all we need to download the file as a blob object. Therefore we introduce a new service method. Let us learn the process of importing the Excel file in an Angular 7 Web Application using Web API with a back-end of the SQL Server database. And after uploading the Excel file, it will display in the UI. A Web API is used to provide data connectivity between the database and the front-end application. How do I create an Excel .XLS www.tumblr.com) file in C# without installing Microsoft Office? Download a file with Android, and showing the progress in a ProgressDialog.

Sign in to your account. I know you want a plunkr that demonstrates the problem, but I'm not sure how to do that since we need a web api, as well as the angular2 code. I have verified that the file is not corrupt but, for some reason, it works just with Angular1, not Angular2.
My service code:. Interestingly enough, in Angular2, if I simply change my webservice to a GET I wanted POST angular 6 download excel file from api, but just to try it out then got rid of the service code and simply made this call, the file is fine:. So, really, what is the difference here? Why does the same or very similar code work for Angular1 but not Angular2??
I'm sorry to not produce a plunkr here. Hopefully, you can help determine if this is a bug or not. I seriously think it is. Just did, plus many other variations. Still have the same problem. The file, when downloaded via the link in Angular2 is 50KB, but when downloaded via the blob code, it is 87 with that change or 94 KB. Almost double in size! The reason I don't to use the link is that I eventually need to make it very secure via a cookie and headers, etc.
No I don't have any examples. Basically angular http is just a wrapper around native xhr. Try to send the same request using hxr and compare results. Hello again I was able to make it work with native xhr. I'm happy with this solution, however I still believe that there is a bug in angular2. You can close this out if you feel you should, however I'm sure someone else will bump up against this one. I've attempted the xhr solution you proposed above but I'm still getting the same issue file is corrupt.
The file downloads with a bizarre filename "e58bc22f-b0cdce20ebb9e6d. I've pasted some code below. Now, whenever I make a GET request, the file downloads on the client-side, but corrupt. The code you pasted above is not any different that what I'm providing below. Any help is much appreciated. I'll continue to investigate and if I figure anything out i'll update the post.
The service looks fine but the component is wrong. You already have a blob your data is a blob and you are creating another blob from the current blob. Thanks for the help! No problem hisham02! It was very frustrating for me to figure this one out so I'm glad I could help! I still call it an angular2 bug since I had to use xhr instead of anguar2 to actually get it to work.
However if I use your code I get error. Any idea? Your answer should be up-voted more! I didn't notice the difference at first. In short, the OP mistake was using responseType as a header. Instead one should use it in get options second argument, type: RequestOptionsArgs.
Thank you all for your contribution. ContentDispositionHeaderValue "attachment" ; response. OK; return response. I have to include FileSaver and it shows the icon to download or save the file.
My backend is in spring. Hi All, I have been trying to download excel in IE 11 using angular and simple java script xhr request but am getting the file as corrupted only in IE 11 or Microsoft Edge.
Chrome and Mozilla works fine. Any help would be appreciable. Researched on IE settings and also tried downloading excel from third party site in Angular 6 download excel file from api which works fine. Below is the code snippet i have been using. Hi All I am able to figure out the issue and resolve it. In my Java service I have added content-length as response header which resolved the issue.
Thanks for the nice article. AulonaBinaj In yours service remove this headers headers. It should resolve your issue and Filesaver should save your file. And Response you attached is correct only. Add content-length header from ur business returning the response. Regards Soma. I tried this, also, I add FileSaver. AulonaBinaj I think your question is a different context. My original file is. Yes this is a problem, I change it to test.

I was also considering looking for some public API like federal gov statistics or similar that returns a spreadsheet, but all I could find so far returns JSON. Here are both methods. Thank you for the xhr suggestion! Open, FileAccess. GetBuffer ; httpResponseMessage. Add "x-filename", fileName ; httpResponseMessage. Length; httpResponseMessage. I have simply this:. Sounds like this was a support request that got resolved so closing.
