我正在构建一个简单的flask应用程序,它允许用户发布数据,我们返回一个RSA公钥加密的base64编码字符串。在
Flask应用程序路径如下所示
def index(eyaml_output=""):
if request.method == 'GET':
return render_template('index.html.j2', eyaml_output=eyaml_output)
elif request.method == 'POST':
input = request.form['eyaml_input']
output = helpers.encrypt(input)
eyaml_output = output
encrypt函数如下所示
^{pr2}$这一切从命令行都能很好地工作。但是当在flask中调用时,我得到以下unicodedecoderror
UnicodeDecodeError: 'ascii' codec can't decode byte 0xda in position 0: ordinal not in range(128)
我尝试过切换到utf-8,但得到了类似的错误
编辑: 我正在用python2.7virtualenv进行测试。输出本身似乎也不重要。即使在执行中间步骤时也会失败,并出现相同的Unicode错误。问题似乎发生在加密部分,而不是base64编码。下面是完整堆栈跟踪

如果在} 的调用,它应该可以工作。
arg
参数上添加对^{encrypt
方法需要一个字节序列,但得到的却是str
