Dart-Base64字符串不等于python [英] Dart - Base64 string is not equal to python
问题描述
当我使用Python生成 base64 字符串时，将在 raw键{'raw'：value} GMAIL API ，发送电子邮件非常方便。
但是当我使用Dart生成相同的 base64 字符串，该字符串与python不同，因此我无法发送电子邮件，因为GMAIL API告诉我 message：无效的值ByteString
将转换为base64的字符串为：
var message ='''< html><元http-equiv = content-type content = text / html; charset = utf-8 />< head>< ; / head>< body> Test< / body>< / html>'''
Python代码：
import base64
e = base64.urlsafe_b64encode（'''< html>< ; meta http-equiv = content-type content = text / html; charset = utf-8 />< head>< / head>< body> Test< / body>< / html> '''）
pri nt（e）
结果：
PGh0bWw-PG1ldGEgaHR0cC1lcXVpdj0iY29udGVudC10eXBlIiBjb250ZW50PSJ0ZXh0L2h0bWw7IGNoYXJzZXQ9dXRmLTgiLz48aGVhZD48L2hlYWQ-PGJvZHk-VGVzdDwvYm9keT48L2h0bWw -
达特代码：
import'dart：convert';
var _bytes = utf8.encode（'''< html><元http-equiv = content-type content = text / html; charset = utf-8 />< head> < / head< body> Test< / body>< / html>'''）;
var _base64 = base64Encode（_bytes）;
print（_base64）;
结果：
PGh0bWw + PG1ldGEgaHR0cC1lcXVpdj0iY29udGVudC10eXBlIiBjb250ZW50PSJ0ZXh0L2h0bWw7IGNoYXJzZXQ9dXRmLTgiLz48aGVhZD48L2hlYWQ + PGJvZHk + VGVzdDwvYm9keT48L2h0bWw +
注意，唯一的区别是 + 登录Dart的base64字符串，并-登录Python的base64字符串
如何我可以生成相同的base64 python代码，因此可以在GMAIL API中发送电子邮件
Dart具有网址安全版本
更改
var _base64 = base64Encode（ _bytes）;
到
var _base64 = base64UrlEncode（_bytes）;
When I use Python to generate a base64 string that will be used in the raw key { 'raw': value } GMAIL API, sending the email occurs perfectly.
But when I use Dart to generate the same base64 string, the string is not the same as python and because of that I can not send the email because the GMAIL API tells me message: Invalid value for ByteString
The string that will be converted to base64 is:
var message = '''<html><meta http-equiv="content-type" content="text/html; charset=utf-8"/><head></head><body>Test</body></html>'''
Python code:
import base64
e = base64.urlsafe_b64encode('''<html><meta http-equiv="content-type" content="text/html; charset=utf-8"/><head></head><body>Test</body></html>''')
print(e)
result:
PGh0bWw-PG1ldGEgaHR0cC1lcXVpdj0iY29udGVudC10eXBlIiBjb250ZW50PSJ0ZXh0L2h0bWw7IGNoYXJzZXQ9dXRmLTgiLz48aGVhZD48L2hlYWQ-PGJvZHk-VGVzdDwvYm9keT48L2h0bWw-
Dart code:
import 'dart:convert';
var _bytes = utf8.encode('''<html><meta http-equiv="content-type" content="text/html; charset=utf-8"/><head></head><body>Test</body></html>''');
var _base64 = base64Encode(_bytes);
print(_base64);
result:
PGh0bWw+PG1ldGEgaHR0cC1lcXVpdj0iY29udGVudC10eXBlIiBjb250ZW50PSJ0ZXh0L2h0bWw7IGNoYXJzZXQ9dXRmLTgiLz48aGVhZD48L2hlYWQ+PGJvZHk+VGVzdDwvYm9keT48L2h0bWw+
Note that the only difference is the + sign in the base64 string of the Dart, and the - sign in the base64 string of Python
How can I generate the same base64 python code, so I can send the email in the GMAIL API
Dart has a URL safe version of Base 64 encode, like Python.
Change
var _base64 = base64Encode(_bytes);
to
var _base64 = base64UrlEncode(_bytes);
