報錯 POST http://192.168.79.165:8015/marketing/manager 400 (BAD REQUEST) 解決辦法

我用jQuery ajax post方法 用flask url_for 傳值到後端 

$.ajax({
	url:"{{url_for('marketing.manager')}}",
	type:'post',
	dataType:'json',
	// data:params,
	data:{'params':'aResult'},
	success:function(data){
		// console.log(data)
		console.log('success')
	},error:function(xhr){
		// console.log(xhr)
		console.log('fail')
	}
})
           

結果出問題了 報出錯誤 POST http://192.168.79.165:8015/marketing/manager 400 (BAD REQUEST)

網上找的網址 https://segmentfault.com/q/1010000004019749/a-1020000004020013

發現問題确實是 後端用了CRSF 前端應該在ajax中加上一個關于crsf的東西

var csrf_token = "{{ csrf_token() }}";
$.ajax({
	url:"{{url_for('marketing.manager')}}",
	beforeSend: function(xhr, settings) {
		if (!/^(GET|HEAD|OPTIONS|TRACE)$/i.test(settings.type) && !this.crossDomain) {
			xhr.setRequestHeader("X-CSRFToken", csrf_token);
		}
	},
	type:'post',
	dataType:'json',
	// data:params,
	data:{'params':'aResult'},
	success:function(data){
		// console.log(data)
		console.log('success')
	},error:function(xhr){
		// console.log(xhr)
		console.log('fail')
	}
})
           

附上解決代碼連結：csrf protection

PS：不過後端一直踩坑 POST，GET不要随意大小寫哦~都是淚
