Let's Try Base64 Encode and Decode with Pyscript
輸入要加密文字:
def on_click(evt):
click_event()
加密文字為:
原始文字為:
input = Element("input_text")
out = Element("enc")
def click_event(*ags, **kwgs):
data = str(input.value)
out.write(data)
#data = 'signatute'
#print(data)
import micropip
micropip.install('base64')
import base64
data = data.encode('utf-8')
result = base64.encodebytes(data).decode('utf-8')
pyscript.write('enc', result)
new_result = base64.decodebytes(result.encode('utf-8')).decode('utf-8')
pyscript.write('dec', new_result)
輸入要解密的字串
def on_click(evt):
click_event2()
解密後的文字為:
input2 = Element("input_text2")
out2 = Element("dec2")
def click_event2(*ags, **kwgs):
data2 = str(input2.value)
out2.write(data2)
try:
dec_result = base64.decodebytes(data2.encode('utf-8')).decode('utf-8')
pyscript.write('dec2', dec_result)
except(ValueError, ArithmeticError):
pyscript.write('dec2', "輸入錯誤")
接下來嘗試將base64編碼的圖片轉回來
輸入Base64編碼的圖片
def on_click(evt):
click_event3()
解密後的圖片為:
input3 = Element("input_text3")
out3 = Element("dec3")
def click_event3(*ags, **kwgs):
data3 = str(input3.value)
#out3.write(data3)
try:
imgdata = base64.b64decode(data3)
pyscript.write('dec3', imgdata)
with open('file.bin', 'wb') as f:
imgdata2 = base64.b64decode(data3)
f.write(imgdata2)
#newimg = document.createElement("img")
#newimg.setAttribute("src", imgdata)
#element = document.getElementById("tem")
#element.appendChild(newimg)
except(ValueError, ArithmeticError):
pyscript.write('dec3', "輸入錯誤")
有點問題，解碼後的圖片無法輸出，只能先用連覽器內建的解碼器顯示圖片
