示例：user.go:
func (u *UserProvider) GetUser(ctx context.Context, userStruct *CallUserStruct) (*User, error) {
fmt.Printf("=======================\nreq:%#v\n", userStruct)
rsp := User{"A002", "Alex Stocks", 18, userStruct.SubInfo}
fmt.Printf("=======================\nrsp:%#v\n", rsp)
return &rsp, nil
}
服务端开启一个服务，名为GetUser，传入一个CallUserStruct的参数，返回一个User参数
CallUserStruct参数定义：
type CallUserStruct struct {
ID string
Male bool
SubInfo SubInfo // 嵌套子结构
}
func (cs CallUserStruct) JavaClassName() string {
return "com.ikurento.user.CallUserStruct"
}
type SubInfo struct {
SubID string
SubMale bool
SubAge int
}
func (s SubInfo) JavaClassName() string {
return "com.ikurento.user.SubInfo"
}
User结构定义：
type User struct {
Id string
Name string
Age int32
SubInfo SubInfo // 嵌套上述子结构SubInfo
}
func (u *User) JavaClassName() string {
return "com.ikurento.user.User"
}
开启服务：
cd serversource builddev.shgo run .
请求体定义为json文件，约定键值均为string
键对应go语言struct字段名例如"ID"、“Name” ，值对应"type@val"
其中type支持string int bool time，val使用string 来初始化，如果只填写type则初始化为零值。
约定每个struct必须有JavaClassName字段，务必与server端严格对应
见userCall.json:
{
"ID": "string@A000",
"Male": "bool@true",
"SubInfo": {
"SubID": "string@A001",
"SubMale": "bool@false",
"SubAge": "int@18",
"JavaClassName":"string@com.ikurento.user.SubInfo"
},
"JavaClassName": "string@com.ikurento.user.CallUserStruct"
}
userCall.json将参数CallUserStruct的结构及子结构SubInfo都定义了出来，并且给请求参数赋值。
user.json 同理，作为返回值不需要赋初始值，但JavaClassName字段一定与server端严格对应
{
"ID": "string",
"Name": "string",
"Age": "int",
"JavaClassName": "string@com.ikurento.user.User",
"SubInfo": {
"SubID": "string",
"SubMale": "bool",
"SubAge": "int",
"JavaClassName":"string@com.ikurento.user.SubInfo"
}
}
