最近一個項目需要用到驗證碼的識別，網上找到了Ocrking的識別平臺，就拿來使用一下。平臺為Java一下是實現方式：

本實例代碼為Java實現本地驗證碼的識別
依賴庫為 httpclient-4.2 使用最新的庫 需要修改部分代碼

?? ???? //構造一個httpclient
?? ??? ?HttpClient client = new DefaultHttpClient();
?? ??? ?HttpPost post = new HttpPost(URL);
?? ??? ?
?? ??? ?//設置請求頭?? 經過測試 如果需要傳入參數 同時要上傳文件 http頭只能設置為如下代碼 或者不予設置
//?? ??? ?post.addHeader("Accept", "*/*");
//?? ??? ?post.addHeader("Referer", "http://lab.ocrking.com");
//?? ??? ?post.addHeader("Accept-Encoding", "gzip");
//?? ??? ?post.addHeader("Accept-Language", "zh-cn,zh,en");
//?? ??? ?post.addHeader("Host", "lab.ocrking.com");
//?? ??? ?post.addHeader("Connection", "Keep-Alive");

?? ??? ?//實例化一個MultipartEntity
?? ??? ?MultipartEntity entity = new MultipartEntity();
?? ??? ?
?? ??? ?try {
?? ??? ??? ?
?? ??? ?File file = new File("C:\\getcodeimage.jpg"); ?
?? ??? ?entity.addPart("url", new StringBody("","text/plain",Charset.forName("UTF-8")));
