这是代码。当我发送两个字段时,它会失败。
import unittest
class UnicodeTestCase(unittest.TestCase):
def test_unicode(self):
from cStringIO import StringIO
from flask import Flask, request
app = Flask(__name__)
app.config['TESTING'] = True
@app.route('/', methods=["POST"])
def test_view():
print request.values, request.files
return "OK"
file = (StringIO("0" * 1000), "filename.txt")
string = u"∆_∆"
client = app.test_client(use_cookies=False)
self.assertEquals(200, client.post('/', data={'file': file}).status_code)
self.assertEquals(200, client.post('/', data={'string': string}).status_code)
self.assertEquals(200, client.post('/', data={'file': file, 'string': string}).status_code)
在最后一个断言中,它失败了:
Error

当我使用Postman(Google Chrome扩展程序)发送这两个字段时,它可以正常工作。
是否可以,我应该使用带有base64或其他东西的unicode包装字段吗?或者它是werkzeug测试客户端中的错误?
答案 0 :(得分:0)
看起来像测试客户端错误,当直接请求工作正常时,我已经有了测试客户端的另一个错误,但是测试客户端有意想不到的结果。
对于我https://github.com/mitsuhiko/werkzeug/blob/master/werkzeug/test.py#L71,我string
类型为str
。对于字符串,仅此方法未被调用,仅对于文件,此方法不会使用您的字符串调用。您可以尝试使用next for python 2临时更新此方法:
def write(string):
if isinstance(string, str):
write_binary(string)
else:
write_binary(string.encode(charset))
我为您的示例创建了错误:https://github.com/mitsuhiko/flask/issues/973。
