https://api.weixin.qq/cgi-bin/message/subscribe/send?access_token=xxxxx

其中access_token就是第四步獲取到的access_token，參數(shù)要寫到url中

之后就是要發(fā)送的數(shù)據(jù)

touser：要發(fā)送給用戶的openId，獲取方法看第三步

template_id：模板id，第一步選擇模板時可以看到模板的id

data：要發(fā)送的數(shù)據(jù)，根據(jù)模板要求的數(shù)據(jù)來裝配

比如模板要求的數(shù)據(jù)是這樣的

那么最后拼湊的數(shù)據(jù)是這樣的

data：{
    thing1：{value:"123"},
    thing2：{value:"123"},
    thing3：{value:"123"},
}

整體數(shù)據(jù)格式

{
    "touser":"XXXX",
    "template_id":"xxxxx",
    "data":{
        "thing1":{"value":"123"},
        "thing2":{"value":"234"},
        "thing3":{"value":"456"}
    }
}

用postMan看的話是這樣的

請求成功后即可。

要注意的是，如果用的是一次性模板，用戶訂閱一次，服務(wù)端才能發(fā)送一次，若需要發(fā)送兩次就需要用戶訂閱兩次（也就是說要訂閱兩次）?。。。。。浚?？？

長期模板的話，用戶點擊訂閱后就不需要重復(fù)訂閱，服務(wù)端也能一直發(fā)送消息。

6.請求的代碼Springboot（自己寫有發(fā)送請求方法的可以不用看）

代碼垃圾，輕點噴?勿噴

SendParam

package ??????;

import org.springframework.http.HttpMethod;

import java.util.Map;


public class SendParam<T> {
    private String url;
    private Object postParam;
    private Map<String,String> getParam;
    private HttpMethod sendType;
    private Class<T> classTr;

    public SendParam() {
        this.sendType = HttpMethod.GET;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public Object getPostParam() {
        return postParam;
    }

    public void setPostParam(Object postParam) {
        this.postParam = postParam;
    }

    public Map<String, String> getGetParam() {
        return getParam;
    }

    public void setGetParam(Map<String, String> getParam) {
        this.getParam = getParam;
    }

    public HttpMethod getSendType() {
        return sendType;
    }

    public void setSendType(HttpMethod sendType) {
        this.sendType = sendType;
    }

    public Class<T> getClassTr() {
        return classTr;
    }

    public void setClassTr(Class<T> classTr) {
        this.classTr = classTr;
    }
}

SendReturn

package ???????;

import org.springframework.http.HttpStatus;

public class SendReturn<T> {
    private boolean isSuccess;
    private String returnString;
    private T obj;
    private HttpStatus statusCode;
    private int statusCodeValue;


    public SendReturn() {
        this.isSuccess=true;
    }

    public boolean isSuccess() {
        return isSuccess;
    }

    public void setSuccess(boolean success) {
        isSuccess = success;
    }

    public String getReturnString() {
        return returnString;
    }

    public void setReturnString(String returnString) {
        this.returnString = returnString;
    }

    public T getObj() {
        return obj;
    }

    public void setObj(T obj) {
        this.obj = obj;
    }

    public HttpStatus getStatusCode() {
        return statusCode;
    }

    public void setStatusCode(HttpStatus statusCode) {
        this.statusCode = statusCode;
    }

    public int getStatusCodeValue() {
        return statusCodeValue;
    }

    public void setStatusCodeValue(int statusCodeValue) {
        this.statusCodeValue = statusCodeValue;
    }
}

SendUtils

package ??????;

import com.google.gson.Gson;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.http.*;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestTemplate;

import javax.annotation.PostConstruct;
import java.util.Map;

@Component
public class SendUtils {

    private static RestTemplate restTemplate;

    @Autowired
    ApplicationContext applicationContext;

    @PostConstruct
    public void init() {
        SendUtils.restTemplate = applicationContext.getBean(RestTemplate.class);
    }

    private static Gson gson = new Gson();


    /**
     * 發(fā)送get請求
     * @param send
     * @return
     */
    public static SendReturn sendGet(SendParam send){
        String url = send.getUrl()+"?";
        if(send.getGetParam()!=null){
            Map<String,String> map = send.getGetParam();
            for(Map.Entry<String,String> entity : map.entrySet()){
                url += entity.getKey()+"="+entity.getValue()+"&";
            }
            url = url.substring(0,url.length()-1);
        }

        SendReturn sendReturn = new SendReturn();
        try{
            ResponseEntity<String> responseEntity = restTemplate.getForEntity(url, String.class);
            if(send.getClassTr()!=null){
                Object o = gson.fromJson(responseEntity.getBody(),send.getClassTr());
                sendReturn.setObj(o);
            }
            sendReturn.setStatusCode(responseEntity.getStatusCode());
            sendReturn.setStatusCodeValue(responseEntity.getStatusCodeValue());
            sendReturn.setReturnString(responseEntity.getBody());
        }catch (Exception e){
            System.out.println(e);
            sendReturn.setSuccess(false);
        }
        return sendReturn;
    }


    /**
     * 發(fā)送post請求
     * @param send
     * @return
     */
    public static SendReturn SendPost(SendParam send){
        SendReturn sendReturn = new SendReturn();
        try{
            ResponseEntity<String> responseEntity = restTemplate.postForEntity(send.getUrl(),send.getPostParam(),String.class);
            if(send.getClassTr()!=null){
                Object o = gson.fromJson(responseEntity.getBody(),send.getClassTr());
                sendReturn.setObj(o);
            }
            sendReturn.setStatusCode(responseEntity.getStatusCode());
            sendReturn.setStatusCodeValue(responseEntity.getStatusCodeValue());
            sendReturn.setReturnString(responseEntity.getBody());
        }catch (Exception e){
            System.out.println(e);
            sendReturn.setSuccess(false);
        }
        return sendReturn;
    }




}

修改請求配置（這里用的是okhttp哈）

RestTemplateConfig

package ？？？？;


import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.OkHttp3ClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;

/**
 * 數(shù)據(jù)請求配置
 */
@Configuration
public class RestTemplateConfig {

    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate(new OkHttp3ClientHttpRequestFactory());
    }


}

maven上要加上okhttp3和gson的依賴哈
