5.5 支付渠道参数查询

5.5.1 交易服务-渠道参数查询接口

5.5.1.1 接口定义1

1、接口描述

1）根据应用和服务类型获取原始支付参数param，结果可能是多个(支付宝param 微信param)

2、接口定义如下：

在PayChannelService接口中定义queryPayChannelParamByAppAndPlatform方法：

/**
     * 根据应用和服务类型查询支付渠道参数列表 结果可能是多个(支付宝param 微信param)
     * @param appId 应用id
     * @param platformChannel 服务类型code
     * @return
     */ 
List<PayChannelParamDTO> queryPayChannelParamByAppAndPlatform(String appId, String platformChannel) throws BusinessException;

5.5.1.2 接口定义2

1、接口描述

1）根据应用、服务类型及支付渠道获取原始支付参数param，结果只能是一个

2、接口定义如下：

在PayChannelService接口中定义queryParamByAppPlatformAndPayChannel方法：

/**
 \* 获取指定应用指定服务类型下所包含的某个原始支付参数
 \* @param appId
 \* @param platformChannel
 \* @param payChannel
 \* @return
 \* @throws BusinessException
 */
PayChannelParamDTO queryParamByAppPlatformAndPayChannel(String appId, String platformChannel,String payChannel) throws BusinessException;

5.5.1.2 接口实现

在PayChannelServiceImpl中实现queryPayChannelParamByAppAndPlatform：

/**
   \* 查询支付渠道参数
   \* @param appId      应用id
   \* @param platformChannel 服务类型代码
   \* @return
   */
@Override
public List<PayChannelParamDTO> queryPayChannelParamByAppAndPlatform(String appId, String platformChannel) {
    //查出应用id和服务类型代码在app_platform_channel主键
    Long appPlatformChannelId = selectIdByAppPlatformChannel(appId,platformChannel);
    //根据appPlatformChannelId从pay_channel_param查询所有支付参数
    List<PayChannelParam> payChannelParams = payChannelParamMapper.selectList(
        new LambdaQueryWrapper<PayChannelParam>()
        .eq(PayChannelParam::getAppPlatformChannelId, appPlatformChannelId));
    return PayChannelParamConvert.INSTANCE.listentity2listdto(payChannelParams);
}

在PayChannelServiceImpl中实现queryParamByAppPlatformAndPayChannel：

@Override 
public PayChannelParamDTO queryParamByAppPlatformAndPayChannel(String appId, String platformChannel, String payChannel) throws BusinessException { 
    List<PayChannelParamDTO> payChannelParamDTOS = queryPayChannelParamByAppAndPlatform(appId, platformChannel); 
    for(PayChannelParamDTO payChannelParam:payChannelParamDTOS){ 
        if(payChannelParam.getPayChannel().equals(payChannel)){ 
            return payChannelParam; 
        } 
    } 
    return null; 
}

5.5.2 商户平台应用-渠道参数查询接口

5.5.2.1 接口定义1

1、接口描述：根据应用和服务类型获取原始支付参数列表

2、接口定义如下：

在PlatformParamController中定义queryPayChannelParam

@ApiOperation("获取指定应用指定服务类型下所包含的原始支付渠道参数列表")
 @ApiImplicitParams({
     @ApiImplicitParam(name = "appId", value = "应用id", required = true, dataType = "String", paramType = "path"),
     @ApiImplicitParam(name = "platformChannel", value = "服务类型", required = true, dataType = "String", paramType = "path")})
 @GetMapping(value = "/my/pay-channel-params/apps/{appId}/platform-channels/{platformChannel}")
 public List<PayChannelParamDTO> queryPayChannelParam(@PathVariable String appId, @PathVariable String platformChannel) {
     return payChannelService.queryPayChannelParamByAppAndPlatform(appId, platformChannel);
 }

5.5.2.1 接口定义2

1、接口描述：根据应用、服务类型及支付渠道获取原始支付参数

2、接口定义如下：

在PlatformParamController中定义queryPayChannelParam

@ApiOperation("获取指定应用指定服务类型下所包含的某个原始支付参数")
@ApiImplicitParams({
    @ApiImplicitParam(name = "appId", value = "应用id", required = true, dataType = "String", paramType = "path"),

    @ApiImplicitParam(name = "payChannel", value = "实际支付渠道编码", required = true, dataType = "String", paramType = "path")})
@GetMapping(value = "/my/pay-channel-params/apps/{appId}/platform-channels/{platformChannel}/pay-channels/{payChannel}")
public PayChannelParamDTO queryPayChannelParam(@PathVariable String appId,
                                               @PathVariable String platformChannel, 
                                               @PathVariable String payChannel) {
    return payChannelService.queryParamByAppPlatformAndPayChannel(appId, platformChannel, payChannel);
}
