HttpClient接口调用
pom.xml文件配置

额外知识点
想直奔主题的童鞋,可跳过该步骤
将接口常量配置到配置文件中（笔者使用的Spring Boot）
修改.yml文件
wbFrame:
# 行情对接配置信息
quote:
quoteUrl: http://192.168.100.24:8080/api/service/depthMarketData
tokenUrl: http://192.168.100.24:8080/api/getAccessToken
loginUrl: http://192.168.102.150:8080/api/service/futuresAccountLogin
获取配置文件中的信息
package net.qmgf.proj.wbmining.common.config;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
/**
* 获取配置文件中信息config
*/
@ConfigurationProperties(prefix = "wbFrame")
@Component
@Data
@NoArgsConstructor
public class WBFrameProperties {
/**
* 行情对接配置
*/
private Quote quote;
/**
* 行情对接配置信息
*
* @author He
*/
@Data
@NoArgsConstructor
public static class Quote {
/**
* 获取内外盘行情url
*/
private String quoteUrl;
/**
* 获取token的url
*/
private String tokenUrl;
/**
* 获取账号登录的url
*/
private String loginUrl;
}
}
DTO & JSON 互相转换
import com.alibaba.fastjson.JSON;
// dto 转 json
String json = JSON.toJSONString(dto)
// json 转 dto
DTO dto = JSON.parseObject(str, DTO.class)
接口对接
LoginDataCtpDto
这里的接口传入和接收DTO都用这一个了,请允许笔者偷懒(手动滑稽)。
