Hello,
My team and I are currently working on issue #4125 as part of our CodeDay internship. Our goal is to create a compressed image function in Java.
The compressed image returned in base64 format is generally good, but we've encountered some cases where escape characters appear (as shown in the attached screenshot 1 & 2), which renders the result invalid.
I attempted to remove these characters using the "replaceAll("\", "")" method, but encountered an error (also shown below screenshot 3).
Could you please advise on the correct way to resolve this issue? Thank you.
public RuntimeResponse main(RuntimeRequest req, RuntimeResponse res) throws Exception {
...
// compressed image in Base64 string
String compressedImage = "";
Map<String, Object> responseData = new HashMap<>();
if (Provider.TINY_PNG.getName().equals(provider)) {
// Decode image from Base64 string
byte[] imageByte = convertToByte(image);
// Compress image
byte[] compressedImageByte = tinifyCompress(imageByte, apiKey);
// Encode image to Base64 string
compressedImage = convertToBase64(compressedImageByte).replaceAll("\\", "");
}
responseData.put("success", true);
responseData.put("image", compressedImage);
return res.json(responseData);
}
Summary
The user is working on a Java code where they are implementing a compressed image function. They are encountering escape characters in the base64 format of the compressed image, which is causing the result to be invalid. They tried to remove the escape characters using "replaceAll("\\", "")", but it resulted in an error. They are seeking advice on how to correctly resolve this issue.
Solution: Instead of using "replaceAll("\\", "")", the user should use "replace("\\", "")" to remove the escape characters from the base64 string.
