∟Test 3 - Save File - Successful

This section provides a tutorial example of testing file upload with the HTTP POST method and multipart/form-data encryption type. The test worked. Uploaded files are saved on the Web server correctly.

I repeated my previous upload test with UploadSave.jspx by using the UploadInit.html page:

File Upload Test Settings:

File upload handler: [UploadSave.jspx]
Submit method: [post]
Encryption type: [multipart/form-data              ]
Submit

On UploadForm page, I selected the same files:

File Upload Form:

Your email: [herong_yang@yahoo.com    ] 
Your comments: [I am uploading two files:     ]
               [   hello.txt                  ]
               [   dot.gif                    ]
File 1: [C:\hello.txt                  ] Browse...
File 2: [C:\dot.gif          ] Browse...
Submit

After clicking the submit button, I got the following result on the returning page:

-----------------------------7d59ec3031a
disposition: null: Content-Disposition: form-data; name="email"
blank: null: 
data: null: herong_yang@yahoo.com
boundary: null: -----------------------------7d59ec3031a
disposition: null: Content-Disposition: form-data; name="comment"
blank: null: 
data: null:  I am uploading two files:

data: null:    dot.gif
boundary: null: -----------------------------7d59ec3031a

type: hello.txt: Content-Type: text/plain
blank: hello.txt: 
boundary: null: -----------------------------7d59ec3031a
disposition: dot.gif: Content-Disposition: form-data; name="file2"...
type: dot.gif: Content-Type: image/gif
blank: dot.gif: 
boundary: null: -----------------------------7d59ec3031a
disposition: null: Content-Disposition: form-data; name="submit"
blank: null: 
data: null: Submit
boundary: null: -----------------------------7d59ec3031a--

To make sure that the uploaded files are saved correctly, I used the following commands in a command window:

C:\>comp \hello.txt 
   \local\apache-tomcat-7.0.32\webapps\ROOT\upload\hello.txt

Comparing \hello.txt and \local\apache-tomcat-7.0.32\webapps\ROOT\u...
Files compare OK

C:\>comp \dot.gif 
   \local\apache-tomcat-7.0.32\webapps\ROOT\upload\dot.gif

Comparing \dot.gif and \local\apache-tomcat-7.0.32\webapps\ROOT\upl...
Files compare OK

Beautiful, my UploadSave.jspx page worked perfectly.
