Springboot图片上传 百度ocr文字识别提取

效果

前提：百度ocr需要自行免费申请，在百度云里面自己申请，获得APP-ID,key和secret的一些必要参数。

需要在pom.xml中添加：（添加使用百度ocr接口的环境）

	
		4.16.3
	

  
        
			com.baidu.aip
			java-sdk
			${baiduocr.version}
		
  

2.在application.yml里面添加OCR配置3.html页面以及js

    
    
    <#include "/header.html">



    
      
        

        <#if shiro.hasPermission("archive:ocr:uploadOcr")>
      识别文本
    
    
      
    

var vm = new Vue({
	el:'#rrapp',
	data:{
		remark:''
	},
	methods: {
		uploadOcr: function (event) {
			var ocrshow=$("#ocrshow").val();
			if(ocrshow){
				let myfile = this.$refs.myfile;
				let files = myfile.files;
				let file = files[0];
				var formData = new FormData();
				formData.append("file", file);
				let url= baseURL + 'archive/ocr/uploadOcr';
				$.ajax({
					type:"POST",
					dataType:"json",
					url:url,
					data:formData,
					async:false,
					cache:false,
					contentType:false,
					processdata:false,
					success:function(res){
						vm.remark=res;
					}
				})
			}else{
				vm.remark="此账号无识别权限!";
			}
		}
	}
});
