map[string]interface{}指针传到dataContext，在做 if 字段判断一直出现panic，求解
const ( data_rule = \
rule "data rule" "a test" salience 10
begin
println(up["status"])
if up["status"] == 1{
return true
}else{
return false
}
end `
)
func Test_check(t *testing.T) {
upDataMap := make(map[string]interface{})
busiz1 := []byte({"reference_id":2073666894,"status":1})
decoder1 := json.NewDecoder(bytes.NewReader(busiz1))
err := decoder1.Decode(&upDataMap)
if err != nil {
fmt.Printf("Unmarshal error, err: %+v", err)
return
}
dataContext := context.NewDataContext()
dataContext.Add("up", &upDataMap)
ruleBuilder := builder.NewRuleBuilder(dataContext)
err1 := ruleBuilder.BuildRuleFromString(data_rule)
if err1 != nil {
panic(err1)
}
eng := engine.NewGengine()
err2 := eng.Execute(ruleBuilder, true)
if err2 != nil {
panic(err2)
}
fmt.Printf("Finish")
}`
if up["status"] == 1，这个地方一直出现panic，求解
up["status"] 返回的是interface，你可以试试把upDataMap := make(map[string]interface{}) 改成 upDataMap := make(map[string]int)
源码中的if判断只能用于number, bool, string 比较，判断数据类型时up["status"] 返回的是interface 不是number 类型
