如何使用Java语言发票查验接口实现发票真伪查验、票据ocr

随着时代潮流的发展，企业也在寻找更加便捷、高效的办公模式，尤其是针对财务工作人员而言，繁琐的发票录入、查验工作占据了财务人员的大部分时间。对此，翔云提供了发票识别接口、发票查验接口，那么企业应当如何将这些接口集成在自己的应用上呢？

其实很简单，开发人员只需要在翔云开发者中心下载所需要的开发语言，更换产品参数便能快速集成，下面，基于Java发票查验接口的开发示例如下：


package com.test;

import okhttp3.*;
import org.json.JSONObject;
import java.io.*;
/**
 * 需要添加依赖
 * 
 * 
 *     com.squareup.okhttp3
 *     okhttp
 *     4.12.0
 * 
 */
class Sample {

	static final OkHttpClient HTTP_CLIENT = new OkHttpClient().newBuilder().build();

	public static void main(String []args) throws IOException{
		MediaType mediaType = MediaType.parse("text/plain");
		RequestBody body = new MultipartBody.Builder().setType(MultipartBody.FORM)
		  .addFormDataPart("key","M***********g")
		  .addFormDataPart("secret","3***********6")
		  .addFormDataPart("typeId","3007")
		  .addFormDataPart("invoiceCode","********")
		  .addFormDataPart("invoiceNumber","*******")
		  .addFormDataPart("billingDate","********")
		  .addFormDataPart("totalAmount","*******")
		  .addFormDataPart("salesTaxNo","*********")
		  .addFormDataPart("checkCode","*******")
		  .addFormDataPart("orderNo","**********")
		  .build();
		Request request = new Request.Builder()
		  .url("https://netocr.com/verapi/v2/verInvoice.do")
		  .method("POST", body)
		  .build();
		Response response = HTTP_CLIENT.newCall(request).execute();
		System.out.println(response.body().string());
	}
}
