The difference between get and post requests in Vue

1. Get request

In a GET request, the parameters follow the URL, that is, the parameters are placed in the header. The parameters that can be transmitted are relatively small. Use params.

this.$http.get(' URL ').then(result=>{
if(result.status===0){
// Success this.list=result.message;
// Here it is assumed that the name of the list in the requested data table is message
}else{
// Failed, pop-up window alert alert("Data request failed");
}
})

2. Post request

In a POST request, the parameters are placed in the body and not following the URL. When using data, the parameter passed is larger.

this.$http.post('URL',{id:this.id},{emulateJSON:true})..then(result=>{
if(result.body.status===0){
// Success }else{
// Failed alert("Failed to obtain data!");
]
})

Vue uses post/get to download and export file operations

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title>Front-end project download export file</title>
	</head>
	<body>
		<script>
			
		/**
		 * post method * Return: file stream * Advantage: you can modify the file name yourself for easy debugging */
	  let params = {      
			ListData : this.ListData     
		}
   	_this.$http.post(url,params,{responseType:"arraybuffer"} //Must add items).then(function(res) {
      console.log(res)
      var blob = new Blob([res.data], {type: 'application/msword; charset=utf-8'});
      var filename = "download.doc";
      var a = document.createElement('a');
      var url = window.URL.createObjectURL(blob);
      a.href = url;
      a.download = filename;
      var body = document.getElementsByTagName('body')[0];
      body.appendChild(a);
      a.click();
      body.removeChild(a);
      window.URL.revokeObjectURL(url);
		}
		
		/**
		 * get method * Return: file stream * Advantages: nothing needs to be processed in the foreground, all processing is done in the background * Disadvantages: unchanged debugging (need to ensure the stability of the background interface)
		 */
		let exportURL = `api/sysLog/export?content=${content}&ip=${ip}`;
   	window.open(exportURL, "_blank")
		
		</script>
	</body>
</html>
