Question

我试图让Docusign使用基于少量参数生成的PDF文档。工作流程为。，用户将生成PDF，然后单击按钮时，将带有带有此PDF的docusign iFrame。用户标志和docusign将把文件发送给我们。在docusign中有很多优秀的API。希望有人能够获得满足这个缩小范围的经验。

-Thanks

从DocuSign Developer Center转到快速入门 - ＆gt; API工具，您将看到一些很棒的工具，例如API Explorer和API演练。 API Walkthroughs有9个最常见的DocuSign API用例，涵盖了6种不同语言的示例代码，适用于所有9种场景，包括Javascript（Node.js）。

您需要的“缩小”用例并不简单，它是我们拥有示例代码的9个常见用例之一。请参阅名为文档上的请求签名的文章。按照复制该代码，填写顶部变量，并在同一文件夹中提供文档的说明进行操作。然后从那里你可以做任何你需要的修改。

以下是该演练的实际javascript：

// Request Signature on a Document (Node.js)

// To run this sample
//  1. Copy the file to your local machine and give .js extension (i.e. example.js)
//  2. Change "***" to appropriate values
//  3. Install async and request packages
//     npm install async
//     npm install request
//     npm install fs
//  4. execute
//     node example.js 
//

var     async = require("async"),       // async module
        request = require("request"),       // request module
        fs = require("fs");         // fs module

var     email = "***",              // your account email
        password = "***",           // your account password
        integratorKey = "***",          // your Integrator Key (found on the Preferences -> API page)
        recipientName = "***",          // recipient (signer) name
        documentName = "***",           // copy document with this name into same directory!
        baseUrl = "";               // we will retrieve this through the Login call

async.waterfall(
  [
    /////////////////////////////////////////////////////////////////////////////////////
    // Step 1: Login (used to retrieve your accountId and baseUrl)
    /////////////////////////////////////////////////////////////////////////////////////
    function(next) {
        var url = "https://demo.docusign.net/restapi/v2/login_information";
        var body = "";  // no request body for login api call

        // set request url, method, body, and headers
        var options = initializeRequest(url, "GET", body, email, password);

        // send the request...
        request(options, function(err, res, body) {
            if(!parseResponseBody(err, res, body)) {
                return;
            }
            baseUrl = JSON.parse(body).loginAccounts[0].baseUrl;
            next(null); // call next function
        });
    },

        // following request body will place 1 signature tab 100 pixels to the right and
        // 100 pixels down from the top left of the document that you send in the request
        var body = {
