utils

Some helper functions for go

Functions

SliceIndex

return the index of the first element in the array that satisfies the provided testing function. Otherwise -1 is returned

GetJson

GetJson make a get request use http.Get

// define a response data type
type Resp struct {
    Status int    `decoder:"status"`
    Msg    string `decoder:"msg"`
}
var res Resp
// this api is always return json data {"status":200, "msg": "hello world}
err := utils.GetJSON("http://zcong-hello.getsandbox.com/hello", &res)
// check error
if err != nil {
    panic(err)
}
// res is response json data
fmt.Printf("%v", res)
//Output: {200 hello world}

GetJsonWithHeaders

GetJsonWithHeaders make a http get request with custom headers

// define your response data type
type Resp struct {}
// define some custom headers
customHeaders := map[string]string{"Foo": "bar"}
var res Resp
// this api return all the request headers
err := utils.GetJSONWithHeaders("http://zcong-hello.getsandbox.com/header", &res, customHeaders)
// res is response data

Compile

Compile is a html template compiler with custom tpl and data

tpl := "hello {{.data}}"
data := map[string]string{"data": "world"}
var d bytes.Buffer
err := utils.Compile(&d, tpl, &data)
// check error
if err != nil {
    panic(err)
}
fmt.Printf("%s", d.String())
// hello world

CompileText

CompileText is same as Compile but use text/template

tpl := "hello {{.data}}"
data := map[string]string{"data": "world"}
var d bytes.Buffer
err := utils.CompileText(&d, tpl, &data)
// check error
if err != nil {
    panic(err)
}
fmt.Printf("%s", d.String())
// hello world

### StringAddress
Get address of const string
```go
str := "zcong1993"
add := StringAddress(str)
// now add is &str without error
