创建一个文字识别的新应用（AppID/APIKey/Secret Key）

后台调用api时需要用到这几个参数。

后台调用照片识别api的方法：

public class picToWord {
    //设置APPID/AK/SK
    public static final String APP_ID = "123456789";
    public static final String API_KEY = "gdsjgiodfjgiofioffjgidfj";
    public static final String SECRET_KEY = "fasdfdsfsdfdsfsdfdfdff";
    public static String getBussinessLicenseMsg(String image) {
        // 初始化一个AipOcr
        AipOcr client = new AipOcr(APP_ID, API_KEY, SECRET_KEY);
        // 传入可选参数调用接口
        HashMap<String, String> options = new HashMap<String, String>();
        // 可选：设置网络连接参数
        client.setConnectionTimeoutInMillis(2000);
        client.setSocketTimeoutInMillis(60000);

        // 参数为本地路径.businessLicense,使用营业执照的接口
        JSONObject res = client.businessLicense(image, options);

        return res.toString(2);

    }
}

前端HTML：

直接调用拍照接口或从相册取出照片需要调用微信的拍照接口(jssdk),这里不做描述

<input type="button" name="Image" title="请选择图片" id="Image">上传

后台代码：

//识别营业执照返回执照信息
@RequestMapping(value = "getBLiscenseMsg")
@ResponseBody
public String getBLiscenseMsg(HttpServletRequest request) {
    //获取前端传来的图片信息
    String pic = request.getParameter("pic");   
    if (!StringUtils.isBlank(pic)) {
        pic = DloadImgUtil.downloadMedias(TokenSchUtil.accessToken_x, pic, "", "");
        pic = pic.split("/")[1];          //解析成.jpg格式
    }
    //调用api得到照片解析后的信息，返回前端ajax
    String picMsg = picToWord.getBussinessLicenseMsg(pic);
    System.out.println("提取营业执照结果:"+picMsg);
    return picMsg;
}

js获取后台返回的信息：

function getPicMsg(){
    var pic = $("#imageUrl").val();      //图片信息
    alert(pic);
    $.ajax({
        url: "getBLiscenseMsg",
        type: "POST",
        data: "pic="+pic,
        dataType: "json",
        success: function (result) {
            //根据返回值的结构提取对应所需的值
            var list = result.words_result;
            var enterpriseName = list["单位名称"].words;
            var chargePerson = list["法人"].words;
            var addr = list["地址"].words;

            //传到前端input文本框
            $('#enterpriseName').val(enterpriseName);  //单位名称
            $('#chargePerson').val(chargePerson);      //法人代表
            $('#managerPerson').val(chargePerson);     
            $('#addr').val(addr);                      //地址
        }
    });
}
