Solving Multiple Requests Issue in the Google Drive API Using Python

If you're a developer who has recently dabbled with the Google Drive API in Python, you might have encountered an annoying issue: being unable to make multiple requests in rapid succession without running into errors like ssl.SSLError: [SSL: WRONG_VERSION_NUMBER]. Don't worry; you're not alone. In this guide, we'll break down this problem, explain its potential causes, and most importantly, guide you through a solution.

The Problem

In a recent query, a user mentioned a specific piece of code that works perfectly when used for a single request but fails when making multiple successive requests. Here’s a brief look at the code structure:

When executing the above lines consecutively, the user encounters an SSL error, thus breaking the flow of their application.

Potential Causes

Http Library Limitations: The Google Drive API is built on the Httplib2 library, which is known to not be thread-safe. Thus, when you execute multiple requests too quickly, it can lead to conflicts.

OAuth2 Client Version: The use of oauth2client, which is deprecated, might contribute to unexpected behaviors, such as connection handling issues.

Network Restrictions: Your requests might be affected by network configurations (like firewalls or proxy configurations) that restrict simultaneous connections.

The Solution

After examining the code and user feedback, the following refactored approach ensures that multiple requests are made more reliably by implementing a more structured connection process.

Step 1: Refactor Credential Management

Instead of handling everything within the main function, we separate the credential fetching process to ensure we only fetch it once:

Step 2: Build the Service with Credentials

Next, you can define a helper function to build the service which utilizes the credentials obtained:

Step 3: Execute Requests with Proper HTTP Handling

To make your requests successfully without encountering the SSL error, configure the HTTP settings explicitly when making calls. Here’s how to do that:

Additional Tip: Implement Delays If Needed

Conclusion

By restructuring how credentials are fetched and managing HTTP sessions properly, you can significantly improve your experience when working with the Google Drive API. This approach ensures that your application runs smoothly, allowing for multiple requests without running into SSL errors.
