In this tutorial, we will learn How to deal with file uploads and downloads.
Dec 25, 2015 This is a simple tutorial on creating an upload feature/mechanism using Python and Flask. I hope it helps. The source code is on github here: https://github.com. The ftplib module in Python allows you to write Python programs that perform a variety of automated FTP jobs. You can easily connect to a FTP server to retrieve files and process them locally. To use the ftplib module in Python, you first have to import it into your script. The syntax to open a file object in Python is: file_object = open(“filename”, “mode”) where file_object is the variable to add the file object. The second argument you see – mode – tells the interpreter and developer which way the file will be used. The ones where you click, and it lets you browse for a file.

If you are using Cloud SQL or MongoDB, set the values under the Cloud SQL or Mongo section to the same values you used during the Using Structured Data step. Set the value CLOUD_STORAGE_BUCKET to your Cloud Storage bucket name. You can use the below function. I haven't tested it yet, but it should work fine. Remember the destination is a directory path where as source is complete file path.
Uploading Files
For this section, we will use http://demo.guru99.com/test/upload/ as our test application. This site easily allows any visitor to upload files without requiring them to sign up.
Uploading files in WebDriver is done by simply using the sendKeys() method on the file-select input field to enter the path to the file to be uploaded.

Let's say we wish to upload the file 'C:newhtml.html'. Our WebDriver code should be like the one shown below.
After running this script, you should be able to upload the file successfully and you should get a message similar to this.
Remember following two things when uploading files in WebDriver
- There is no need to simulate the clicking of the 'Browse' button. WebDriver automatically enters the file path onto the file-selection text box of the <input type='file'> element
- When setting the file path in your Java IDE, use the proper escape character for the back-slash.
Downloading Files
WebDriver has no capability to access the Download dialog boxes presented by browsers when you click on a download link or button. However, we can bypass these dialog boxes using a separate program called 'wget'.
What is Wget?
Wget is a small and easy-to-use command-line program used to automate downloads. Basically, we will access Wget from our WebDriver script to perform the download process.
Setting up Wget
Step 1: In your C Drive, create a new folder and name it as 'Wget'.
Download wget.exe from here and Place it in the Wget folder you created from the step above.
Step 2: Open Run by pressing windows key + 'R' ; type in 'cmd & click ok
Type in the command 'cd /' to move to the root directory

Step 3: Type in the command to check whether the given setup is working
There seems to be an issue writing into C drive.
Step 4: You need to debug the wget errors in command line before you execute the code using Selenium Webdriver. These errors will persist in Eclipse and the error messages will not be as informative. Best to first get wget working using command line. If it works in command line it will definitely work in Eclipse.
In our example, as show in step 3, there is a problem writing into C drive. Let's change the download location to D drive and check results.
Messenger was downloaded successfully.
Before you proceed further don't forget to delete the downloaded file
Using WebDriver and Wget
In the following example, we will use WebDriver and wget to download a popular chat software called Yahoo Messenger. Our base URL shall be http://demo.guru99.com/test/yahoo.html.
Step 1
Import the 'java.io.IOException' package because we will have to catch an IOException later in Step 4.
Step 2
Use getAttribute() to obtain the 'href' value of the download link and save it as a String variable. In this case, we named the variable as 'sourceLocation'.
Step 3
Set-up the syntax for wget using the following command.
Step 4
Initiate the download process by calling wget from our WebDriver code.
To sum it all up, your WebDriver code could look like the one shown below.
After executing this code, check your D drive and verify that the Yahoo Messenger installer was successfully downloaded there.
Summary
- Uploading files in WebDriver is done by simply using the sendKeys() method on the file-select input field to enter the path to the file to be uploaded.
- WebDriver cannot automate downloading of files on its own.
- The easiest way to download files using WebDriver is to use Wget.
Can someone please illustrate how to upload a file via ftp from within calc (to a specific folder)
I'm using python but If you can do it in oo basic that's fine too.
So far, i've been able to make a python script to upload a file to the root directory
and I'm testing it from dos prompt outside of Calc.
However I'm left now with two problems that I need help with please.
1. I can't seem to change directory on the ftp site so as to deliver the file to the correct folder and not the root.
How To Upload A Csv File In Python
(keep getting this error message: TypeError: cwd() missing 1 required positional argument: 'dirname'I have tried many variations for the directory argument; 'mychosenfolder' - '/mychosenfolder/' '//mychosenfolder//'
and even assigned the string to a variable and used that in the FTP.cwd statmente (as in the code below)
But still get the same error message. And YES, the folder does exist and it is writeable to.
2. I need specific instructions as to how to run the python script from within calc.
All the links I've gone to seem to give all manner of definitions of API components etc. but no example of how to do this.
I'm running OO 4. using Python3 on a windows vista OS. Below is the code I'm using which like I said will upload successfully to the root ftp if I don't try to change the directory.
Sendspace
- Code: Select allExpand viewCollapse view
# ftpfileupload.py
# uploads a named file to a specific directory on a website
import ftplib
from ftplib import FTP
print('Conecting to FTP server . . . Please wait . . ')
session = FTP('www.somewebsite.com','username','password')
file = open('sample.txt','rb') # file to send
# print(FTP.pwd()) # Get the current path - this does work either
myfolder = '/mychosenfolder/'
FTP.cwd(myfolder) # Change Directory
print('Uploading File Now . . . Please wait . . ')
session.storbinary('STOR sample.txt', file) # send the file
print('File Uploaded')
file.close() # close file and FTP
session.quit()
