HttpClient接口調用

HttpClient接口調用

pom.xml文件配置

		<dependency>
		    <groupId>commons-httpclient</groupId>
		    <artifactId>commons-httpclient</artifactId>
		    <version>3.1</version>
		</dependency>

額外知識點

想直奔主題的童鞋,可跳過該步驟

將接口常量配置到配置文件中（筆者使用的Spring Boot）

修改.yml文件

wbFrame:
  # 行情對接配置信息
  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

獲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;

/**
 * 獲取配置文件中信息config
 */
@ConfigurationProperties(prefix = "wbFrame")
@Component
@Data
@NoArgsConstructor
public class WBFrameProperties {

	/**
	 * 行情對接配置
	 */
	private Quote quote;

	/**
	 * 行情對接配置信息
	 *
	 * @author He
	 */
	@Data
	@NoArgsConstructor
	public static class Quote {
		/**
		 * 獲取內外盤行情url
		 */
		private String quoteUrl;
		/**
		 * 獲取token的url
		 */
		private String tokenUrl;
		 /**
         * 獲取賬號登錄的url
         */
        private String loginUrl;
	}

}

DTO & JSON 互相轉換

import com.alibaba.fastjson.JSON;

// dto 轉 json
String json = JSON.toJSONString(dto)

// json 轉 dto
DTO dto = JSON.parseObject(str, DTO.class)

接口對接

LoginDataCtpDto

這裏的接口傳入和接收DTO都用這一個了,請允許筆者偷懶(手動滑稽)。

package

net.qmgf.proj.wbmining.fut.dto;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.experimental.Accessors;
import net.qmgf.frame.common.base.model.BaseEntityDto;

/**
 * 
 * @author He
 * @date 2020年6月9日
 * @version 1.0
 *
 */
@Data
@EqualsAndHashCode(callSuper = true)
@Accessors(chain = true)
@ApiModel(value = "ctp賬號登錄信息")
public class LoginDataCtpDto extends BaseEntityDto {

	private static final long serialVersionUID = 1L;

	/**
	 * 經紀商ID
	 */
	@ApiModelProperty(value = "經紀商ID")
	private String brokerId;
	/**
	 * 用戶ID
	 */
	@ApiModelProperty(value = "用戶ID")
	private String userId;
	/**
	 * 登錄狀態
	 */
	@ApiModelProperty(value = "登錄狀態")
	private Boolean loginStatus;

}

LoginCtpDto

package

net.qmgf.proj.wbmining.fut.dto;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;

import java.util.List;

import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.experimental.Accessors;
import net.qmgf.frame.common.base.model.BaseEntityDto;

/**
 * 
 * @author He
 * @date 2020年6月9日
 * @version 1.0
 *
 */
@Data
@EqualsAndHashCode(callSuper = true)
@Accessors(chain = true)
@ApiModel(value = "ctp賬號登錄返回信息")
public class LoginCtpDto extends BaseEntityDto {

	private static final long serialVersionUID = 1L;

	/**
	 * 狀態
	 */
	@ApiModelProperty(value = "狀態")
	private Boolean status;

	/**
	 * data
	 */
	@ApiModelProperty(value = "data")
	private List<LoginDataCtpDto> data;

}
