http format - LME OPEN API

protocol：https/http

context-type: json

HTTP Methods：POST

request headers:

key name	key type	is required	default value	remark
requestid	string	true		unique
appkey	string	true		created by LME system
version	string	true	1.0
timestamp	string	true
sign	string	true

request body:

parameter name	parameter type	is required	default value	remark
data	string	true

encrypt parameters:

lmePublicKey: created by LME

thirdPublicKey, thirdPrivateKey: from partner, RSA keys

encrypt step：

1、encrypt business parameters with utf-8

data = encryptByPublicKey(Json.toString(parameters), String lmePublicKey);

2、generate sign

pattern: appKey=%s+"&"+data=%s+"&"+timeStamp=%s

sign = sign(String thirdPrivateKey,String pattern)

request demo:

response format:

parameter name	parameter type	is required	default value	remark
logId	String	false
code	Long	true	0
message	String	false	SUCCESS	the message of business result
data	string	true

response demo:

decrypt step:
1、validate sign

pattern: appKey=%s&data=%s(encryptData)&timeStamp=%s
validateSign = signByPublicKey(String pattern, String lmePublicKey)
if the header sign equals validateSign, validate result success

2、decrypt data
decryptData = decryptByPrivateKey(encryptData, thirdPrivateKey)
