<script type="text/javascript">
一、获取url所有参数值
function US() {
var name, value
var str = location.href
var num = str.indexOf("?")
str = str.substr(num + 1)
var arr = str.split("&")
for (var i = 0 i < arr.length i++) {
num = arr[i].indexOf("=")
if (num > 0) {
name = arr[i].substring(0, num)
value = arr[i].substr(num + 1)
this[name] = value
}
}
}
二、使用JS 发送JSON格式的POST请求
var us = new US()
var xhr = new XMLHttpRequest()
xhr.open("POST", "/searchguard/api/v1/auth/login", true)
xhr.setRequestHeader("Content-type", "application/json")
xhr.setRequestHeader("kbn-version", "5.3.0")
xhr.onreadystatechange = function() {
if (xhr.readyState == 4) {
if (xhr.status == 200) {
window.location.href = us.nextUrl
}
}
}
xhr.send(JSON.stringify({
"username" : us.u,
"password" : us.p
}))
</script>
$.ajax({url:"（你要请求的url地址）",
data:{
"key1" : "value1",
"key2" : "value2"
},
type:"post", //此处传递方式可以是get也可以是post
dataType:"json", //后台要返回的数据形式
success:function(data){//请求成功的要执行的回调函数
console.log('请求成功')
console.log(data)
},
error:function(msg){//请求失败的要执行的回调函数
console.log('请求失败')
console.log(msg)
}
})
