<h1>一导通签名说明</h1>
<h2>必传参数</h2>
<ul>
<li>
<p>requestData: 入参数据内容（URl编码：UTF8）</p>
</li>
<li>
<p>eBusinessID: 用户ID</p>
</li>
<li>
<p>requestType: 请求指令类型</p>
</li>
<li>
<p>dataSign: 数据内容签名(请求内容(未编码)+ApiKey)进行MD5 加密，然后Base64
编码，最后进行URL(utf-8)编码</p>
</li>
<li>dataType: 2(返回数据类型为json)</li>
</ul>
<p>注册后会生成对应会生成对应的用户ID 和APIKey，用户ID 相当于用户名，APIKey 相当于密码。</p>
<h2>举例</h2>
<ol>
<li>假设</li>
</ol>
<p>RequestData (JSON)内容为：
<code>{'OrderCode':'','ShipperCode':'SF','LogisticCode':'118954907573'}</code>
经过URL(UTF-8)编码的内容为：
<code>%7B%27OrderCode%27%3A%27%27%2C%27ShipperCode%27%3A%27SF%27%2C%27LogisticCode%27%3A%27118954907573%27%7D</code>
EBusinessID=1237100【示例ID，不可用来实际使用】
APIKey=56da2cf8-c8a2-44b2-b6fa-476cd7d1ba17【示例Key，不可用来实际使用】</p>
<ol>
<li>DataSign签名内容</li>
</ol>
<pre><code>{'OrderCode':'','ShipperCode':'SF','LogisticCode':'118954907573'}56da2cf8-c8a2-44b2-b6
fa-476cd7d1ba17</code></pre>
<p>经过md5 和base64 后的内容就为：
<code>OWFhM2I5N2ViM2U2MGRkMjc4YzU2NmVlZWI3ZDk0MmE=</code>，
在经过URL(UTF-8)编码的内容为：
<code>OWFhM2I5N2ViM2U2MGRkMjc4YzU2NmVlZWI3ZDk0MmE%3D</code>
最终要发送的数据为：
<code>RequestType=1002&EBusinessID=1237100&RequestData =%7b%27OrderCode%27%3a%27%27%2c%27ShipperCode%27%3a%27SF%27%2c% 27LogisticCode%27%3a%27118954907573%27%7d&DataSign =OWFhM2I5N2ViM2U2MGRkMjc4YzU2NmVlZWI3ZDk0MmE%3d&DataType=2</code></p>
<ol>
<li>接收方收到数据后，获得EBusinessID 和RequestData 和DataSign 等这几个数据。</li>
<li>接收方对EBusinessID 得到APIKey，RequestData+APIKey 的数据进行md5 和base64 后的内容就为OWFhM2I5N2ViM2U2MGRkMjc4YzU2NmVlZWI3ZDk0MmE=</li>
<li>接收方判断签名后的数据跟传递过来的DataSign 是否一致，如果一致进行业务操作，如果不一致返回错误。</li>
</ol>
