服务端 SDK

更新时间：2019-08-13

SDK 获取

开发语言 资源下载 环境要求
JAVA 版资源 Maven项目依赖 适用于 Java 语言、JDK 版本 1.5 及以上的开发环境
.NET 版资源 SDK 适用于 Visual Studio 2010 及以上版本、Framework 3.5 SP1 及以上版本的开发环境
PHP 版资源 SDK 适用于 PHP 5.5 以上的开发环境
PYTHON 版资源 PyPI项目依赖 适用于 Python 2.7 及以上版本的开发环境
NodeJS 版资源 NPM项目依赖 适用于 Node.js v8.0.0 及以上版本的开发环境

SDK 集成

  1. 注意：由于实例化SDK客户端时需要指定应用的私钥信息，请务必注意不要将私钥信息配置在源码中（比如配置为常量或储存在配置文件的某个字段中等），因为私钥的保密等级往往比源码高得多，将会增加私钥泄露的风险。推荐将私钥信息储存在专用的私钥文件中，将私钥文件通过安全的流程分发到服务器的安全储存区域上，仅供自己的应用运行时读取。
  2. SDK已经对加签验签逻辑做了封装，使用SDK可直接调用API。
  3. 确定接口对应的类
    例如接口名：alipay.offline.material.image.upload
    在SDK中对应的类为：每个单词首字母大写，并去掉分隔符（“.”），末尾加上Request（或Response）
    如上接口名对应的类为：
    AlipayOfflineMaterialImageUploadRequest（请求类）
    AlipayOfflineMaterialImageUploadResponse（响应类）
    具体调用方式见下方各语言。

Java SDK 集成示例

SDK 包说明

  • alipay-sdk-java*.jar—————————支付宝SDK编译文件jar

  • alipay-sdk-java*-source.jar——————支付宝SDK源码文件jar

  • commons-logging-1.1.1.jar——————SDK依赖的日志jar

  • commons-logging-1.1.1-sources.jar———SDK依赖的日志源码jar

注意

  • 集成支付宝接口需要引入的文件是：
    alipay-sdk-java*.jar
    commons-logging-1.1.1.jar

  • 若进一步了解代码实现请引入文件：
    alipay-sdk-java*-source.jar
    commons-logging-1.1.1-sources.jar

普通调用示例

//实例化客户端
AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do", APP_ID, APP_PRIVATE_KEY, "json", CHARSET, ALIPAY_PUBLIC_KEY, "RSA2");
//实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.open.public.template.message.industry.modify 
AlipayOpenPublicTemplateMessageIndustryModifyRequest request = new AlipayOpenPublicTemplateMessageIndustryModifyRequest();
//SDK已经封装掉了公共参数，这里只需要传入业务参数
//此次只是参数展示，未进行字符串转义，实际情况下请转义

AlipayOpenPublicTemplateMessageIndustryModifyResponse response = alipayClient.execute(request); 
//调用成功，则处理业务逻辑

方法说明

加签方法（如果不用 SDK 调用，推荐用该方法加签）

/**
@param content 待签名字符串
@param privateKey 加签私钥
@param charset 加签字符集
@param sign_type 签名方式
**/
String AlipaySignature.rsaSign(String content, String privateKey, String charset, String sign_type)

验签方法（例如异步通知的时候，用户需要用到验签方法）

验签方法，根据接口不同，验签时会去掉sign_type(rsaCheckV1)或者保留sign_type(rsaCheckV2)。

/**    此方法会去掉sign_type做验签，暂时除生活号（原服务窗）激活开发者模式外都使用V1。
@param params 参数列表(包括待验签参数和签名值sign) key-参数名称 value-参数值
@param publicKey 验签公钥
@param charset 验签字符集
@param sign_type 验签方式（RSA或RSA2）
**/
boolean AlipaySignature.rsaCheckV1(Map<String, String> params, String publicKey, String charset, String sign_type)

/**    此方法不会去掉sign_type验签，用于生活号（原服务窗）激活开发者模式
@param params 参数列表(包括待验签参数和签名值sign) key-参数名称 value-参数值
@param publicKey 验签公钥
@param charset 验签字符集
@param sign_type 验签方式（RSA或RSA2）
**/
boolean AlipaySignature.rsaCheckV2(Map<String, String> params, String publicKey, String charset, String sign_type)

注意事项

  • AlipayClient 的实现类都是线程安全的，所以没有必要每次 API 请求都新建一个 AlipayClient 实现类；

  • 创建 AlipayClient 实现类的实例时，指定 format=json，相比 xml 格式，可以减少数据传输量，提升 API 请求效率。
