DocuSign API-JavaScript

Question

下午！ 我是JavaScript和DocuSign API的新手。 我尝试按照示例进行操作，但是遇到了ReferenceError。

为了进行测试，我在PC上文件夹的根目录中有async.js，fs.js，request.js和require.js以及测试HTML文档

HTML：

<html>
<head>
        <script src="require.js"></script>
        <script src="example.js"></script>

</head>

<body>
<div id="message"></div>
</body>

</html>

我收到以下错误：ReferenceError：未定义async async.waterfall（

以下是我从DocuSign网站获得的example.js代码，根据require函数周围的另一个错误对它进行了调整：

// Request Signature on a Document (JavaScript)

// 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

require(["request"], function (request){});
require(["async"], function (async){});
require(["fs"], function (fs){});

再次，我对此很陌生，因此，非常感谢您的帮助，在此先感谢您！

更新-在意识到我无法在QuickBase代码页上使用的node.js片段之后，我尝试了以下两个编码选项，但都没有起作用……任何想法我做错了什么？

var xhr = createCORSRequest('GET', urlLoginCall);
xhr.withCredentials = true;
xhr.setRequestHeader('X-DocuSign-Authentication', jsonLoginCall);
xhr.send(); 
xhr.onload = function() {
    var responseText = xhr.responseText;
    alert(responseText);
};
xhr.onerror = function() {
    alert('There was an error!');
};

和

$.ajax({
    type: 'GET',
    url: urlLoginCall,
    headers: {
        'X-DocuSign-Authentication': jsonLoginCall
    },
    xhrFields: {
        withCredentials: true
    },
    success: function() {
        alert("success");
    },
    error: function() {
        alert("failure");
    }
});

通过Fidler，我总是将其作为请求标头：

OPTIONS /restapi/v2/login_information HTTP/1.1
Host: demo.docusign.net
Connection: keep-alive
Access-Control-Request-Method: POST
Origin: https://twmts.quickbase.com
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.146 Safari/537.36
Access-Control-Request-Headers: x-docusign-authentication
Accept: */*
Referer: https://twmts.quickbase.com/db/bhkhmzax6?a=dbpage&pageID=145
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8

这作为响应头：

HTTP/1.1 200 OK
Cache-Control: no-cache
Date: Mon, 10 Mar 2014 12:15:48 GMT
Content-Length: 0
Strict-Transport-Security: max-age=7776000; includeSubDomains

没有返回XML或JSON。 我知道这一定很简单，我只是不明白，但是我花了很多时间tryig来确定我所缺少的东西，除了不使用node.js之外，我无法弄清楚。

您引用的DocuSign示例代码使用Node.js模块，更具体地说，它使用request ， async和fs模块。 您似乎已经注释了导入所需的Node.js库的三行：

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

require语句加载不同的模块，并且当您注释掉上面的代码时，它不知道async.waterfall函数是什么，因为它没有在任何地方声明。 要解决该问题，请尝试取消注释上面的代码，结果如下：

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