Question

我正在向Docusign API提出一些请求，并且我收到了错误消息{＆＃34; errorCode＆＃34;：＆＃34; UNSPECIFIED_ERROR＆＃34;，＆＃34; message＆＃ 34;：＆＃34; Base-64字符数组或字符串的长度无效。＆＃34;当我试图通过电子邮件方式发送电子签名请求时发送文件。

我在请求正文中发送的以下JSON：

                "signHereTabs": [
                    {

                    }
                ]
            }
        }
    ]
},
"status": "sent"

}

一些其他信息。我通过asp经典调用来做这个请求。它已经正常工作以获取登录信息和令牌数据。这就是我发送请求的方式。

我已经计算过，编码的值是有效的base64内容。

有人可以帮我解决这个问题吗？

Answer 1

我在我的机器上使用一个简单的PDF测试文件进行了测试...这是编码文件内容的JS函数：

var handleFileSelect = function(evt) {
var files = evt.target.files;
var file = files[0];

if (files && file) {
    var reader = new FileReader();

    reader.onload = function(readerEvt) {
        var binaryString = readerEvt.target.result;
        document.getElementById("hidden_doc").value = btoa(binaryString);
    };

    reader.readAsBinaryString(file);
}
var fullPath = document.getElementById('document').value;
if (fullPath) {
    var startIndex = (fullPath.indexOf('\\') >= 0 ? fullPath.lastIndexOf('\\') : fullPath.lastIndexOf('/'));
    fileName = fullPath.substring(startIndex);
    if (fileName.indexOf('\\') === 0 || fileName.indexOf('/') === 0) {
        fileName = fileName.substring(1);
    }
}

};

另外，如您所见，我有一个文件输入类型来选择文件：

<input type="file" id="document" accept=".pdf"/>

Answer 2

我已经解决了这个问题。我的base64功能错了。

现在我正在使用以下功能，它运行正常：

function previewFile() {
var preview = document.getElementById("hidden_doc");
var file    = document.querySelector('input[type=file]').files[0];
var reader  = new FileReader();

reader.addEventListener("load", function () {
    preview.value = reader.result.split(',')[1];
}, false);

if (file) {
    reader.readAsDataURL(file);
}

var fullPath = document.getElementById('document').value;
if (fullPath) {
    var startIndex = (fullPath.indexOf('\\') >= 0 ? fullPath.lastIndexOf('\\') : fullPath.lastIndexOf('/'));
    fileName = fullPath.substring(startIndex);
    if (fileName.indexOf('\\') === 0 || fileName.indexOf('/') === 0) {
        fileName = fileName.substring(1);
    }
}   

}

感谢大家的帮助。
