assert interface{} to int64-CodePudding

i am using gin, i use c.shouldBind to bind the data to the struct, the use c.set to set the params in the context. when i use c.getInt64 to get the params, it can't return the value i set in the context(i set a 1), it return a zero. it failed to assert a float64 1 to a int64 0.

i have google it but can't get the answer i want

here are my debug code

// GetInt64 returns the value associated with the key as an integer.
func (c *Context) GetInt64(key string) (i64 int64) {
    if val, ok := c.Get(key); ok && val != nil {
        i64, _ = val.(int64)
    }
    return
}

the val is 1, but it returns 0

So can anybody tell me why and how to solve it.

CodePudding user response：

Golang can't convert types implicitly. You can use the GetFloat64 method.

CodePudding user response：

It depends the value which you really set in, and check the key is right, After that, Maybe you could use assertion after Get like: value := c.Get("From_validator_page").(Int64)
