OCR開發demo源碼-SDK下載-薪火科技

提示：下載源碼后需要改3個地方(1.接口地址；2.type；3.token)，具體參照接口文檔。

1.JAVA版demo

public static void main(String[] args) throws Exception {

String serverUrl = "http://api.xinhuokj.com:28901/ocr"; //服務端地址
String token = "9b242b-----------4c2b4b6f01b"; //注冊后生成的token (登錄、注冊的網址 http://www.qdtingmei.com/user)

byte[] imgData = FileUtil.readFileByBytes("test.jpg"); //讀取待測試的圖片
String imgStr = Base64Util.encode(imgData); //把圖片轉成base64編碼
String params = "{\"type\":\"0\", \"image\": \"" + imgStr + "\", \"token\":\"" + token + "\" } "; //把參數拼接成json字符串
String res = HttpUtil.postGeneralUrl(serverUrl, "application/json", params, "UTF-8"); //向服務端發送http請求，返回識別結果
System.out.println(res );

}

2.PHP版demo

$base64 = filetobase64('img.jpg'); //讀取圖片的base64值
$post_data = array(
'image' => $base64,
'type' => 0,
'token'=>'b4de50360-------5cddddc3klf8d9em' //您的token，可在http://www.qdtingmei.com/user獲取
);
$url = "http://api.xinhuokj.com:28901/ocr";
$post_str = json_encode($post_data);
$data = request_post($url, $post_str);
$data = strstr($data, '{');
echo $data;
}

3.C++版demo

#include <httplib.h>
#include <nlohmann/json.hpp>
#include <base64.hpp>
#include <utils.hpp>
#include <iostream>
#include <string>
using json = nlohmann::json;
using namespace xhai;

int main(int argc, char* argv[]) {

if(argc != 2) {

std::cout << "usage: demo ./img.jpg" << std::endl;
return -1;

}
httplib::Client cli("api.xinhuokj.com", 28901);

std::string image_data;
get_file_content(argv[1], &image_data);

json data;
data["token"] = "b4de50360------cddddcopkjytrks"; //您的token，可在http://www.qdtingmei.com/user獲取
data["image"] = base64_encode(image_data.c_str(), image_data.size());
data["type"] = "0";
std::string data_str = data.dump();

auto res = cli.Post("/ocr", data_str.c_str(), "application/json");
if (res && res->status == 200) {

auto ret_data = json::parse(res->body);
std::cout << ret_data.dump() << std::endl;

int num = ret_data["words_result_num"];
std::cout << "word_num: " << num << std::endl;
auto words_result = ret_data["words_result"];
for(auto it: words_result) {

std::cout << it["words"] << std::endl;

}

4.C#版demo

using System;
using System.IO;
using System.Net;
using System.Text;

namespace ocr_demo_.net
{

class Program
{

static void Main(string[] args)
{

string token = "b4de50360------cddddcopkjytrks";//注冊后生成的token (登錄、注冊的網址http://www.qdtingmei.com/user)
string host = "http://api.xinhuokj.com:28901/ocr" ;
Encoding encoding = Encoding.Default;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(host);
request.Method = "post";
request.KeepAlive = true;
// 圖片的base64編碼
string base64 = fileToBase64("demo.jpg");//待測試的圖片
String str = "{\"type\":\"0\", \"image\": \"" + base64 + "\", \"token\":\"" + token + "\" } ";
byte[] buffer = encoding.GetBytes(str);
request.ContentLength = buffer.Length;
request.GetRequestStream().Write(buffer, 0, buffer.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.Default);
string result = reader.ReadToEnd();
Console.WriteLine("OCR 通用識別:");
Console.WriteLine(result);

}

public static String fileToBase64(String fileName)
{

FileStream filestream = new FileStream(fileName, FileMode.Open);
byte[] arr = new byte[filestream.Length];
filestream.Read(arr, 0, (int)filestream.Length);
string baser64 = Convert.ToBase64String(arr);
filestream.Close();
return baser64;

}

5.Python版demo

# encoding:utf-8
import requests
import base64
request_url = "http://api.xinhuokj.com:28901/ocr"
token = "b4de50360------cddddcopkjytrks"#注冊后生成的token (登錄、注冊的網址http://www.qdtingmei.com/user)
# 二進制方式打開圖片文件
f = open('test.jpg', 'rb')
img = base64.b64encode(f.read())
params = { "image": str( img, encoding="utf-8" ), "token": token, "type": 0}
headers = { 'content-type': 'application/json' }
response = requests.post(request_url, data = json.dumps(params), headers = headers)
if response:
print (response.json())
else:
print (response)

6.nodejs版demo

const fs = require('fs')
// 先安裝request，執行 npm install request 即可
const request = require('request')

const token = '8f127********************5b7' //請到個人中心獲取token，http://www.qdtingmei.com/user
const url = 'http://api.xinhuokj.com:40072/ocr'

// 文件的base64編碼數據
var image = fs.readFileSync('./test.jpg').toString('base64')

request({

url: url,
method: 'POST',
json: true,
headers: {
'content-type': 'application/json',
},
body: {

token: token,
image: image,
type:11

}

}, function(error, response, body) {

if (!error ) {
// 請求成功的處理邏輯
console.log(body)
}

})
