python各种post上传文件

1、带证书上传文件

filename = '/tmp/test.cert'

hash_v = 'assumethisisahash'

#这是一种流式上传的方式

with open(filename, 'rb') as f:

....requests.post(link, data={'hash': hash_v}, files={'filename':f}, verify='/tmp/test.cert')

2、最简单的流式上传

with open('massive-body') as f:
    requests.post('http://some.url/streamed', data=f)

3、块编码请求

def gen():
    yield 'hi'
    yield 'there'

requests.post('http://some.url/chunked', data=gen())

4、复杂的流式上传，为了兼容中文文件，还对文件名称中途做了一个replace替换

def get_content_code(url, res_path, encoded_name, file_name):
    with open(res_path, 'rb') as f_:
        m = MultipartEncoder(
            fields={'file': (encoded_name, f_,
                             'application/octet-stream')}
        )
        utils.logger.info('body:{},encoded_name:{},file_name:{}'.format(m,encoded_name,file_name))

        decoded_m = m.to_string()
        decoded_m=decoded_m.replace(encoded_name, file_name)
        utils.logger.info('decoded_m:{}'.format(decoded_m))
        utils.logger.info('url:{}'.format(url))
        response = requests.post(url,
                                 data=decoded_m,
                                 headers={'Content-Type': m.content_type,
                                          'charset': 'UTF-8'})
        utils.logger.info('content: {}'.format(response.content))

        try:
            content = json.loads(response.content)
        except ValueError:
            content = response.content
        return content, response.status_code
