base64上傳圖檔遇到的問題

def maintainFileSaveAction(String base64img, String fileName) {

base64img = base64img.substring(base64img.indexOf(",") + 1).replaceAll(" ", "+");

}

要删掉檔案的無效部分

// 1）截取擷取到的base64編碼,去掉字首"data:image/png;base64," || "data:image/jpeg;base64,",隻取base64編碼

// 2）需要将 base64編碼 中的空格轉換成 + 号

userPhoto = userPhoto.substring(userPhoto.indexOf(",") + 1).replaceAll(" ", "+");
