# 1.编写Java代码实现识别图片中Latex公式 #

直接上代码：

public static String serverUrl = "接口地址";
        public static String accessToken = "***";
        public static String appKey = "您的appKey";
        public static String appSecret ="您的appSecret";
        public static Map<String,String> getLatex(String img){
            Map<String,String> addMap = new HashMap<String,String>();
            try {
                Img2LatexRequest request=new Img2LatexRequest();
                request.setImg(img);
                ZrscClient client = new DefaultZrscClient(serverUrl, accessToken, appKey,
                        appSecret);
                Img2LatexResponse response= client.execute(request);
                addMap.put("img",img);
                addMap.put("latex",response.getData());
                return addMap;
            } catch (Exception e) {
                e.printStackTrace();
            }
            return addMap;
    
        }

Img2LatexRequest

public class Img2LatexRequest extends AbstractRequest implements ZrscRequest<Img2LatexResponse> {
        private String img;
    
        public String getImg() {
            return img;
        }
    
        public void setImg(String img) {
            this.img = img;
        }
    
        public Img2LatexRequest() {
    
        }
        public String getApiMethod() {
            return "img2latex.get";
        }
    
        public String getAppJsonParams() throws IOException {
            Map<String, Object> pmap = new TreeMap();
            pmap.put("img",this.img);
            return JsonUtil.toJson(pmap);
        }
    
        @Override
        public Class<Img2LatexResponse> getResponseClass() {
            return Img2LatexResponse.class;
        }
    
    }

Img2LatexResponse

public class Img2LatexResponse extends AbstractResponse {
        private static final long serialVersionUID = -1029647126543204295L;
        public Img2LatexResponse(){}
        private String data;
        @JsonProperty("data")
        public String getData() {
            return data;
        }
        @JsonProperty("data")
        public void setData(String data) {
            this.data = data;
        }
    }
