python-requests和EchoSign

Question

我正在尝试将文件发布到EchoSign API中，除了python请求之外，它对我来说无处不在。

我这里有完美的CURL命令

curl -H "Access-Token: API_KEY" \
 -F File=@/home/user/Desktop/test123.pdf \
 https://secure.echosign.com/api/rest/v2/transientDocuments

这是我的请求功能。它将上传PDF文件，但有垃圾，而CURL工作完美。

api_url = 'https://secure.echosign.com/api/rest/v2'

def send_document(file_path, access_token=access_token):
    """Uploads document to EchoSign and returns its ID

   :param access_token: EchoSign Access Token
   :param file_path: Absolute or relative path to File
   :return string: Document ID

   """
    headers = {'Access-Token': access_token}

    url = api_url + '/transientDocuments'

    with open(file_path, 'rb') as f:
        files = {
            'File': f,
        }
        return requests.post(url, headers=headers, files=files).json().get('transientDocumentId')

我做错了什么？我已经尝试将文件作为数据而不是文件发布，但仍然没有不同的结果

由于

修改

我添加

时有效

data = {
    'Mime-Type': 'application/pdf',
    'File-Name': 'abc.pdf'
}

所以，我的新功能是：

def send_document(file_path, access_token=access_token):
    """Uploads document to EchoSign and returns its ID

    :param access_token: EchoSign Access Token
    :param file_path: Absolute or relative path to File
    :return string: Document ID

    """
    headers = {
        'Access-Token': access_token,
    }
    data = {
        'Mime-Type': 'application/pdf',
        'File-Name': 'abc.pdf'
    }
    url = api_url + '/transientDocuments'
    files = {'File': open(file_path, 'rb')}
    return requests.post(url, headers=headers, data=data,
                         files=files).json().get('transientDocumentId')

Answer 1

这就是它的工作原理

def send_document(file_path, access_token=access_token):
    """Uploads document to EchoSign and returns its ID

    :param access_token: EchoSign Access Token
    :param file_path: Absolute or relative path to File
    :return string: Document ID

    """
    headers = {
        'Access-Token': access_token,
    }
    data = {
        'Mime-Type': 'application/pdf',
        'File-Name': 'abc.pdf'
    }
    url = api_url + '/transientDocuments'
    files = {'File': open(file_path, 'rb')}
    return requests.post(url, headers=headers, data=data,
                         files=files).json().get('transientDocumentId')

Answer 2

尝试传递文件名和mime-type，如下所示：

files = {
    'File': (
        os.path.basename(file_path),
        f,
        'application/pdf',
    )
}
