python-requests和EchoSign

Question

我想將一個文件發佈到EchoSign API中，除了python-requests外，它對我來說無處不在。

我這裏curl命令完美的作品

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

，這是我的請求的功能。它將上傳PDF文件，但帶有垃圾，而CURL完美工作。

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') 

我在做什麼錯？我曾嘗試張貼的文件數據，而不是文件太大，仍然沒有不同的結果

感謝

編輯

當我加入

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

所以它的工作，我的新功能將是：

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

這它是如何工作的

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

嘗試通過在文件名和MIME類型，像這樣：

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