Question

url: https://uhome.haier.net:6503/css/v1/protected/familyService/family
appKey: e8a1e19058c0928d7690cfd59c6b062d
appId: SV-ABC-0000
serviceKey: e8a1e19058c092fdfd328dd59c6b062d
serviceId: UWS-FML-0000
timestamp: 1234567890
Body:
{
"userId":"u12",
"deviceType":"101c120024000810e2010540000044"
}

待签名字符串:
/css/v1/protected/familyService/family{"userId":"u12","deviceType":"101c120024000810e2010540000044"}SV-ABC-0000e8a1e19058c0928d7690cfd59c6b062d

求教 /css/v1/protected/familyService/family{"userId":"u12","deviceType":"101c120024000810e2010540000044"} 这一段是怎么拼接成的 用什么方法？

Answer 1

当然可以，JSON字符串跟普通字符串没有任何区别， JS中用 + 即可拼接

Answer 2

json字符串也是字符串，照常处理就行
