#Download excel vba takes files from ftp download
In order to download a file, we make an HTTP Get request, then read the response content into a memory stream which can be copied to a physical file. Lines 23 and 24 receive the HTTP response for later use. Line 21 sends the HTTP post request when the request content is ready. The values can only be represented as strings, and the server side app will have to parse them into correct data types. Lines 17 to 19 are examples of adding key/value pairs to the MultipartFormDataContent object. The key can be different when multiple files are included in a form.
Line 16 adds the file content to the form object, and sets the key to be “file”. If the ContentType is not set, then it will default to be application/json, which is not what we want here. Note: When a file is included in a form, the enctype attribute should always be “multipart/form-data”, which specifies that the form will be sent as a multipart MIME message. Lines 14 and 15 create a ByteArra圜ontent object from the file content, and sets the ContentType header to be “multipart/form-data”. Then line 13 instantiates a MultipartFormDataContent object, which is the request content sent to the server side app. The method UploadFile(string filePath) first validates the physical file. The complete source code is in my GitHub repository. This blog post intends to provide the missing guide. However, most of tutorials and blog posts don’t talk much about sending FormData with a file object and a collection of key/value pairs using HttpClient. Based on this article in Microsoft Docs, it is straightforward to send HTTP requests and receive HTTP responses. When an application needs to talk to another system, it is quite common that the application sends data to and receives data from the other system using HttpClient in the back-end. The client side app is a Console project, which contains a Typed HttpClient to send HTTP requests for file uploading and/or downloading. The server side app is an ASP.NET Core web project, which includes a Web API controller for uploading and downloading files. We will create two applications to demonstrate the data transfer between the client side and the server side. sub downloadfile () dim myurl as string myurl ' dim winhttpreq as object set winhttpreq createobject ('microsoft.xmlhttp') winhttpreq.open 'get', myurl, false, 'username', 'password' nd myurl winhttpreq.responsebody if winhttpreq.status 200 then set ostream createobject ('adodb.
