4.11 可选sign签名算法

我们用ERP调用VWMS URL演示加密算法：

http:// sandbox.vwms.cn/open/service?method=openapi.stockout.create&timestamp=2015-04-26 00:00:07&format=xml&app_key=testerp_appkey&v=2.0&sign=abc&sign_method=md5&customerId=stub-cust-code

4.11.1 输入参数为

method= openapi.stockout.create

timestamp=2015-04-26 00:00:07

format=xml

app_key= testerp_appkey

v=2.0

sign_method=md5

customerId =test

4.11.2 按首字母升序排列

app_key= testerp_appkey

customerId = stub-cust-code

format=xml

method= openapi.stockout.create

sign_method=md5

timestamp=2015-04-26 00:00:07

v=2.0

4.11.3 连接字符串

连接参数名与参数值,并在首尾加上secret，此处假设secret=test，如下：

testapp_keytesterp_appkeycustomerIdstub-cust-codeformatxmlmethod openapi.stockout.createsign_methodmd5timestamp2015-04-26 00:00:07v2.0_body_test

其中：body用请求中的body数据代替

4.11.4 生成签名sign

4.11.5 拼装URL请求

将所有参数值转换为UTF-8编码，然后拼装，并作URL ENCODING 如下:

http://sandbox.vwms.cn/open/service?method= opeanapi.stockout.create&timestamp=2015-04-26%2000:00:07&format=xml&app_key=testerp_appkey&v=2.0&sign=D06D88CB34B2EC0E5C9BAB396C9542B6&sign_method=md5&customerId=stub-cust-code
