Understanding the 'C:fakepath' Discrepancy in File Selection Paths
When selecting a file using HTML's file input control, you may encounter a seemingly fictitious path like "C:fakepath" instead of the actual local file location. This apparent path is not a true filesystem location but rather a placeholder browser security measure.
Why Does This Happen?
Some browsers implement this security feature to prevent malicious websites from accessing the user's local filesystem. By reporting a fake path instead of the true one, it limits the potential for data breaches and privacy issues.
Getting the True Local File Path
While browsers restrict access to the true local file path, there are legitimate scenarios where it is necessary, such as for local processing or storage. In these cases, you must resort to alternative approaches that respect browser security measures.
One option is to use the FileReader API to read the selected file's contents and save them to a local file. The FileReader API provides methods like readAsText() and readAsArrayBuffer() to obtain the file's content. Alternatively, you can use the Blob API to create a file from the selected file and then save it to the user's system.
Conclusion
While browser security measures prevent direct access to the true local file path, alternative methods like the FileReader and Blob APIs can be employed to achieve the desired functionality while respecting browser security concerns.
