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);}@Overridepublic 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;}}
