4条解答一.困惑啊!!用zxing读取图片当中的条形码
参考zxing二维码扫描的流程简析(Android版)JavaCodeExamplesforcom。google 。zxing。DecodeHintTypeReadingQRCodewithZxinginJava设置一下TryHarder和PossibleFormats看一下publicstaticListScanForBarcodes(stringpath){returnScanForBarcodes(newBitmap(path));}publicstaticListScanForBarcodes(Bitmapbitmap){//initializeanewBarcodereader。BarcodeReaderreader=newBarcodeReader{TryHarder=true,//TryHarderisslowerbutrecognizesmoreBarcodesPossibleFormats=newList//intheZXingThereisanEnumwhereallsupportedbarcodeFormatswerecontained{BarcodeFormat 。CODE_128,BarcodeFormat。QR_CODE,//BarcodeFormat。 。。。;}};returnreader 。DecodeMultiple(bitmap)。Select(result=>result。Text) 。ToList();//returnonlythebarcodestring 。//IfyouwantthefullResultuse:returnreader。DecodeMultiple(bitmap);}。
二.怎么判断文本框的验证码和 picturebox背景图片的验证码相
if((["CheckCode"].Value,,true)!=0){="验证码错误,请输入正确的验证码 。";=true;return;}我的是这样判断的!
三.java如何读取网络照片呢
importjava。io。BufferedInputStream;importjava 。io。BufferedOutputStream;importjava。io 。FileOutputStream;importjava。net。HttpURLConnection;importjava 。net。URL;importjava。net 。URLConnection;/ 。读取网络照片,保存到本地**/publicclassGetUrlImg{publicstaticvoidgetUrlImg(StringURLName,Stringtarget)throwsException{//URLName照片地址//target本地地址intHttpResult=0;//服务器返回的状态URLurl=newURL(URLName);//创建URLURLConnectionurlconn=url。openConnection();//试图连接并取得返回状态码urlconn。connect();HttpURLConnectionhttpconn=(HttpURLConnection)urlconn;HttpResult=httpconn 。getResponseCode();System。out。println(HttpResult);if(HttpResult!=HttpURLConnection 。HTTP_OK)//不等于HTTP_OK说明连接不成功System。out。print("fail");else{intfilesize=urlconn 。getContentLength();//取数据长度System。out。println(filesize); 。
