该服务是基于.net的服务。以下是python代码
URL = 'http://vp-testprocessor-service-bdp-dev.dev.xxxxxxxxxxxxxx.com/api/testprocessor/v1/testprocessors/requests'
headers = {'Authorization': 'Bearer 00000000-0000-0000-adb2-3087bcbcdaf7',
'Accept': 'applicaiton/json',
'Content-Type': 'audio/x-wav;type=alaw;bit=16;rate=8000;channels=1',
'User-Agent': 'Mozilla/5.0 AppleWebkit/537.36 Chrome/41.0.2272.101 Safari/537.36'}
session = requests.Session()
with open(input_file, 'rb') as fd:
data = fd.read()
request = requests.Request('POST', url, data = data, headers = headers)
prepped = session.prepare_request(request)
response = session.send(prepped, allow_redirects=False)这是python3的输出。

谢谢。

我在头文件中看到了拼写错误，应该是python代码中的'Accept':'application/json‘，而不是'Accept':'applicaiton/json’
