用java代码调用名片识别接口示例代码接口地址：/docs/api/id/139接口名称：名片识别调用语言：java文档参数：请求参数：名称类型必填说明imagestring是名片图像的base64串langstring否语言种类，简体:chns,繁体:chnt,英文:en，默认chnscolorstirng否图像类型，gray:进行了灰度处理 ，original：原图，建议进行灰度处理keystring是应用APPKEY(应用详细页查询)dtypestring否返回数据的格式,xml或json，默认json根据名片识别接口的文档要求可以看出key是调用聚合平台的所有接口的一个令牌,所以必须先注册登录然后申请该数据,这里不做赘述,主要示例调用的代码。另一个必须参数是image，根据说明可以看出，这个参数是读取图片的char数组转为string类型后再经过加密的字符串，所以必须用到base64这个加密工具类。建议使用mons.codec.binary.Base64这个类,下载地址:/proper/commons-codec/download_codec.cgi下面是网络访问工具类:;importjava.io.BufferedReader;importjava.io.BufferedWriter;importjava.io.InputStream;importjava.io.InputStreamReader;importjava.io.OutputStream;importjava.io.OutputStreamWriter;.HttpURLConnection;.URL;importjava.util.Map;importjava.util.zip.GZIPInputStream;/*网络访问工具类*authorsilk*/publicclassPureNetUtil/*get方法直接调用post方法*paramurl网络地址*return返回网络数据*/publicstaticStringget(Stringurl)returnpost(url,null);publicstaticStringget(Stringurl,Stringcharset)returnpost(url,null,charset);/*设定post方法获取网络资源,如果参数为null,实际上设定为get方法*paramurl网络地址*paramparam请求参数键值对*return返回读取数据*/publicstaticStringpost(Stringurl,Mapparam)returnpost(url,param,null);publicstaticStringpost(Stringurl,Mapparam,StringoutCharset)if(outCharset=null)outCharset=UTF-8;HttpURLConnectionconn=null;tryURLu=newURL(url);conn=(HttpURLConnection)u.openConnection();conn.setRequestProperty(User-agent,Mozilla/5.0(WindowsNT6.1)AppleWebKit/537.36(KHTML,likeGecko)Chrome/29.0.1547.66Safari/537.36);StringBuffersb=null;if(param!=null)/如果请求参数不为空sb=newStringBuffer();/*AURLconnectioncanbeusedforinputand/oroutput.SettheDoOutput*flagtotrueifyouintendtousetheURLconnectionforoutput,*falseifnot.Thedefaultisfalse.*/默认为false,post方法需要写入参数,设定trueconn.setRequestMethod(POST);conn.setDoOutput(true);/设定post方法,默认get/获得输出流OutputStreamout=conn.getOutputStream();/对输出流封装成高级输出流BufferedWriterwriter=newBufferedWriter(newOutputStreamWriter(out);/将参数封装成键值对的形式for(Map.Entrys:param.entrySet()sb.append(s.getKey().append(=).append(s.getValue().append(&);writer.write(sb.deleteCharAt(sb.toString().length()-1).toString();writer.close();/如果忘记关闭输出流将造成参数未完全写入的情况sb=null;conn.connect();/建立连接sb=newStringBuffer();/获取连接状态码intrecode=conn.getResponseCode();BufferedReaderreader=null;if(recode=404)System.out.println(404=+url);if(recode=200)/Returnsaninputstreamthatreadsfromthisopenconnection/从连接中获取输入流InputStreamin=conn.getInputStream();Stringencoding=conn.getContentEncoding();if(encoding!=null&encoding.equalsIgnoreCase(gzip)GZIPInputStreamgis=newGZIPInputStream(in);reader=newBufferedReader(newInputStreamReader(gis,outCharset);for(Stringstr=reader.readLine();str!=null;str=reader.readLine()sb.append(str).append(System.getProperty(line.separator);/原网页的换行加上elsereader=newBufferedReader(newInputStreamReader(in,outCharset);for(Stringstr=reader.readLine();str!=null;str=reader.readLine()sb.append(str).append(System.getProperty(line.separator);/原网页的换行加上/关闭输入流reader.close();if(sb.toString().length()=0)returnnull;returnsb.toString().substring(0,sb.toString().length()-System.getProperty(line.separator).length(); catch(Exceptione)e.printStackTrace();returnnull;finallyif(conn!=null)/关闭连接conn.disconnect();returnnull;下面是调用代码:packageorg.silk.mingpianshibie;importjava.io.File;importjava.io.FileInputStream;importjava.io.InputStream;importjava.util.HashMap;importjava.util.Map;mons.codec.binary.Base64;.PureNetUtil;publicclassCardAPIDemoprivatestaticfinalStringKEY=您申请的appKey;privatestaticfinalStringURL=/hanvon/bcard/query;privatestaticfinalStringPATH=D:1.jpg;publicstaticvoidmain(Stringargs)System.out.println(invoke();publicstaticStringinvoke()Mapparams=newHashMap();Filefile=newFile(PATH);InputStreamin;tryin=newFileInputStream(file);inti=in.available();/得到文件大小bytedata=newbytei;in.read(data);/读数据in.close();params.put(key,KEY);Base64base64=newBase64(true);params.put(image,base64.encodeToString(data);returnPureNetUtil.post(URL,params);catch(Exceptione)e.printStackTrace();returnnull;打印结果:reason:successed,result:rotatedAngle:null,name
