我发表了几篇关于将Docusign的Python SDK与我公司的web应用程序集成的文章。从本质上讲，我要做的是让用户填写一份表格，在用户单击提交按钮后，weasyprint会从我创建的html模板中生成一个pdf，并将客户的信息放在正确的位置。然后，我希望DocuSign用新生成的PDF向用户发送一封电子邮件，让他们在表格上签名，并将其发送到我公司的电子邮件帐户。以下是我尝试将Python的SDK集成到Django web应用程序中的方法：
def Signview(request):
loa = LOA.objects.filter().order_by('-id')[0] # This is pulling the information about the user from a model in my database
username = "myusername@docusign.com"
integrator_key = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
base_url = "https://demo.docusign.net/restapi"
oauth_base_url = "account-d.docusign.com"
redirect_uri = "http://localhost:8000/path/to/redirecturi"
private_key_filename = "path/to/pKey.txt"
user_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
client_user_id = 'Your System ID' # This is the actual string I am using for this variable
# Add a recipient to sign the document
signer = docusign.Signer()
signer.email = loa.email
signer.name = loa.ainame
signer.recipient_id = '1'
signer.client_user_id = client_user_id
sign_here = docusign.SignHere()
sign_here.document_id = '1'
sign_here.recipient_id = '1'
sign_here.anchor_case_sensitive = 'true'
sign_here.anchor_horizontal_alignment = 'left'
sign_here.anchor_ignore_if_not_present = 'false'
sign_here.anchor_match_whole_word = 'true'
sign_here.anchor_string = 'Sign Here'
sign_here.anchor_units = 'cms'
sign_here.anchor_x_offset = '0'
sign_here.anchor_y_offset = '0'
sign_here.tab_label = 'sign_here'
tabs = docusign.Tabs()
tabs.sign_here_tabs = [sign_here]
# Create a signers list, attach tabs to signer, append signer to signers.
# Attach signers to recipients objects
signers = []
tabs = tabs
signer.tabs = tabs
signers.append(signer)
recipients = docusign.Recipients()
recipients.signers = signers
# Create an envelope to be signed
envelope_definition = docusign.EnvelopeDefinition()
envelope_definition.email_subject = 'My email subject'
envelope_definition.email_blurb = 'My email blurb'
# Add a document to the envelope_definition
pdfpath = "path/to/mypdf.pdf"
with open(pdfpath, 'rb') as signfile:
file_data = signfile.read()
doc = docusign.Document()
base64_doc = base64.b64encode(file_data).decode('utf-8')
doc.document_base64 = base64_doc
doc.name = "MyDoc_Signed.pdf"
doc.document_id = '1'
envelope_definition.documents = [doc]
signfile.close()
envelope_definition.recipients = recipients
envelope_definition.status = 'sent'
api_client = docusign.ApiClient(base_url)
oauth_login_url = api_client.get_jwt_uri(integrator_key, redirect_uri, oauth_base_url)
print("oauth_login_url:", oauth_login_url)
print("oauth_base_url:", oauth_base_url)
api_client.configure_jwt_authorization_flow(private_key_filename, oauth_base_url, integrator_key, user_id, 3600)
docusign.configuration.api_client = api_client
auth_api = AuthenticationApi()
envelopes_api = EnvelopesApi()
try: #login here via code
login_info = auth_api.login()
login_accounts = login_info.login_accoutns
base_url, _ = login_accounts[0].base_url.split('/v2')
api_client.host = base_url
docusign.configuration.api_client = api_client
envelope_summary = envelopes_api.create_envelope(login_accounts[0].account_id, envelope_definition = envelope_definition)
print(envelope_summary)
except ApiException as e:
raise Exception("Exception when calling DocuSign API: %s" % e)
except Exception as e:
print(e)
return HttpResponse({'sent'})
然而，这是我运行以下代码时收到的错误：

我已经在我的DocuSign管理页面上输入了带有集成密钥的重定向URI，我已经转到链接并点击"接受"，这样就可以同意开始签名，然而，这是我遇到的问题，我不确定出了什么问题。这里的一位同事向我提供了这个解决方案，他告诉我，代码应该可以工作，而且很可能是DocuSign管理方面我没有做的事情。这里的代码有什么明显的错误吗？
提前感谢！
很难定义管理面板中的错误。您可以尝试完成以下步骤来定义错误：
- 检查admin和代码中的重定向uri是否相同
- 在管理面板中检查user_id是否与您的API用户名相同(这是我的问题(
- 确保路径/to/pKey.txt中的私钥与管理面板中的私钥相同
我希望它会有帮助。
