本實(shí)例代碼為Java實(shí)現(xiàn)本地驗(yàn)證碼的識(shí)別

依賴庫為 httpclient-4.2 使用最新的庫 需要修改部分代碼

Author: niostars@gmail.com

//構(gòu)造一個(gè)httpclient

HttpClient client = new DefaultHttpClient();

HttpPost post = new HttpPost(URL);

//設(shè)置請求頭?? 經(jīng)過測試 如果需要傳入?yún)?shù) 同時(shí)要上傳文件 http頭只能設(shè)置為如下代碼 或者不予設(shè)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(shí)例化一個(gè)MultipartEntity

MultipartEntity entity = new MultipartEntity();

try {

File file = new File("C:\\getcodeimage.jpg");

entity.addPart("url", new StringBody("","text/plain",Charset.forName("UTF-8")));

entity.addPart("service", new StringBody("OcrKingForCaptcha","text/plain",Charset.forName("UTF-8")));

entity.addPart("language", new StringBody("eng","text/plain",Charset.forName("UTF-8")));

entity.addPart("charset", new StringBody("7","text/plain",Charset.forName("UTF-8")));

entity.addPart("apiKey", new StringBody(apiKey,"text/plain",Charset.forName("UTF-8")));

entity.addPart("type", new StringBody(type,"text/plain",Charset.forName("UTF-8")));

/*addPart 建議使用上面的代碼進(jìn)行設(shè)置*/

//?? ??? ??? ?entity.addPart("url", new StringBody(""));

//?? ??? ??? ?entity.addPart("service", new StringBody("OcrKingForCaptcha"));

//?? ??? ??? ?entity.addPart("language", new StringBody("eng"));

//?? ??? ??? ?entity.addPart("charset", new StringBody("7"));

//?? ??? ??? ?entity.addPart("apiKey", new StringBody(apiKey));

//?? ??? ??? ?entity.addPart("type", new StringBody(type));

/*加入文件*/

entity.addPart("filename",new FileBody(file));

} catch (Exception e1) {

// TODO Auto-generated catch block

e1.printStackTrace();

}

try {

post.setEntity(entity);

System.out.println("executing request="+post.getRequestLine());

HttpResponse response = client.execute(post);

System.out.println("code="+response.getStatusLine().getStatusCode());

System.out.println(EntityUtils.toString(response.getEntity()));

}
