Upload files using ASP and VBScript (2)

Upload script usage
    
The following is an example of a script Upload application. The downloaded files in this article provide the files and code in the example. Release the compressed file to a path and configure a virtual path for your network server. You can test and start uploadform.html in the browser.
    
Call scripts
    
The following describes how to call the BuildUploadRequest method. First, call a full dictionary: UploadRequest. Then, call the BuilUploadRequest method and send it to the original binary data of the request in the independent variable.
    
ByteCount = Request. TotalBytes
RequestBin = Request. BinaryRead (byteCount)
Dim UploadRequest
Set UploadRequest = CreateObject ("Scripting. Dictionary ")
BuildUploadRequest RequestBin
    
Data is decomposed and stored in a dictionary object and restored using the Item () method. The item data can be stored in VBScript variables and can be used anywhere in the code. Data can be transmitted back to the client as a response, used in ASP code, written into a file, and stored in a database.
    
Retrieve data
    
The data of the UploadRequest object can be accessed using the Item ("key") function. Now let's take a look at this situation: you need to access an email-controlled value. You can do this:
    
Email = UploadRequest. Item ("email"). Item ("Value ")
    
This is a text class control, and the content is a string, which can be used like any other VBScript string.
You can use the same method to restore binary data:
    
Picture = UploadRequest. Item ("blob"). Item ("Value ")
    
You can also access other information, such as the file name and content-type. They are text class control.
