文章标签 java企业微信审批开发微信 apache json 文章分类 Java 后端开发

结合几位大佬的代码后实现此功能：感谢大佬让我完成此功能的实现，如有侵权，立刻删除。
借鉴文章地址：
java调用企业微信接口发送消息。介绍的十分详细，相当感动，图片加代码。（这个是发送普通文本消息的）一下子代码就通过了。
corpID之类的页面参数告诉在哪里获取，支持下作者。
微信小程序客服消息新增临时素材接口java实现
代码

一、实体类：
注意：json字符串和实体类是对应的：一定要对应，我就是没有对应导致浪费一天半时间在修改40007错误。最后发现我输出出来的json和官方文档的不一样。这个是我踩的最大的坑media_id明明获取到了，确报40007media_id不合法，让我一直以为是我id获取错了，换了接口等，怎么都不好使。最后发现官方文档请求数据是这样的

我的是：
“media_id”：“获取到的media_id”没有前面的file。
相差这么大我竟然没发现，最后还是我公司哥给我发现的。希望自己以后认真一点吧。

/**
* 微信消息发送实体类

public class WeChatData {
//发送微信消息的URLString sendMsgUrl="https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=";
/**
* 成员账号
*/
private String touser;
/**
* 消息类型
*/
private String msgtype;
/**
* 企业应用的agentID
*/
private int agentid;
/**
* 实际接收Map类型数据
*/

private Object file;

public String getMsgtype() {
return msgtype;
}
public void setMsgtype(String msgtype) {
this.msgtype = msgtype;
}
public int getAgentid() {
return agentid;
}
public void setAgentid(int agentid) {
this.agentid = agentid;
}

this.touser = touser;
}

public Object getFile() {

}

public void setFile(Object file) {

}

二、微信授权请求

public class WeChatUrlData {
/**
* 企业Id
*/
private String corpid;
/**
* secret管理组的凭证密钥
*/
private String corpsecret;
/**
* 获取ToKen的请求
*/
private String Get_Token_Url;
/**
* 发送消息的请求
*/
private String SendMessage_Url;
public String getCorpid() {
return corpid;
}
public void setCorpid(String corpid) {
this.corpid = corpid;
}
public String getCorpsecret() {
return corpsecret;
}
public void setCorpsecret(String corpsecret) {
this.corpsecret = corpsecret;
}
public void setGet_Token_Url(String corpid,String corpsecret) {
this.Get_Token_Url ="https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid="+corpid+"&corpsecret="+corpsecret;
}
public String getGet_Token_Url() {
return Get_Token_Url;
}
public String getSendMessage_Url(){
SendMessage_Url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=";
return SendMessage_Url;
}
}

三、微信发送消息

import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;
import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import org.slf4j.LoggerFactory;

import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.HashMap;
import java.util.Map;

public class WeChatMsgSend {
private CloseableHttpClient httpClient;
/**
* 用于提交登陆数据
*/
private HttpPost httpPost;
/**
* 用于获得登录后的页面
*/
private HttpGet httpGet;


public static final String CONTENT_TYPE = "Content-Type";


SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");


private static Gson gson = new Gson();


/**
* 微信授权请求，GET类型，获取授权响应，用于其他方法截取token
* @param Get_Token_Url
* @return String 授权响应内容
* @throws IOException
*/
protected String toAuth(String Get_Token_Url) throws IOException {


httpClient = HttpClients.createDefault();
httpGet = new HttpGet(Get_Token_Url);
CloseableHttpResponse response = httpClient.execute(httpGet);
String resp;
try {
HttpEntity entity = response.getEntity();
resp = EntityUtils.toString(entity, "utf-8");
EntityUtils.consume(entity);
} finally {
response.close();
}
LoggerFactory.getLogger(getClass()).info(" resp:{}", resp);
return resp;
}


/**corpid应用组织编号 corpsecret应用秘钥
* 获取toAuth(String Get_Token_Url)返回结果中键值对中access_token键的值
* @param
*/
public String getToken(String corpid,String corpsecret) throws IOException {
WeChatMsgSend sw = new WeChatMsgSend();
WeChatUrlData uData = new WeChatUrlData();
uData.setGet_Token_Url(corpid,corpsecret);
String resp = sw.toAuth(uData.getGet_Token_Url());
System.out.println("resp=====:"+resp);
try{
Map<String, Object> map = gson.fromJson(resp,new TypeToken<Map<String, Object>>() {}.getType());
return map.get("access_token").toString();
}catch (Exception e) {
return resp;
}
}

/**
* @Title:创建微信发送请求post数据
* touser发送消息接收者 ，msgtype消息类型（文本/图片等），
* application_id应用编号。
* media_id文件id，可以调用上传临时素材接口获取
* 本方法适用于text型微信消息，contentKey和contentValue只能组一对
* @return String
*/
public String createpostdata(String touser, String msgtype,
int application_id,String file,Object media_id) {
WeChatData wcd = new WeChatData();
wcd.setTouser(touser);
wcd.setAgentid(application_id);
wcd.setMsgtype(msgtype);
Map<Object, Object> content = new HashMap<Object, Object>();
content.put(file,media_id);
wcd.setFile(content);

return gson.toJson(wcd);
}


/**
* @Title 创建微信发送请求post实体
* charset消息编码 ，contentType消息体内容类型，
* url微信消息发送请求地址，data为post数据，token鉴权token
* @return String
*/
public String post(String charset, String contentType, String url,
String data,String token) throws IOException {
CloseableHttpClient httpclient = HttpClients.createDefault();
httpPost = new HttpPost(url+token);
httpPost.setHeader(CONTENT_TYPE, contentType);
httpPost.setEntity(new StringEntity(data, charset));
CloseableHttpResponse response = httpclient.execute(httpPost);
String resp;
try {
HttpEntity entity = response.getEntity();
resp = EntityUtils.toString(entity, charset);
EntityUtils.consume(entity);
} finally {
response.close();
}
LoggerFactory.getLogger(getClass()).info("call [{}], param:{}, resp:{}", url, data, resp);
return resp;
}
}

四、上传临时文件获取media_id

public class UploadMeida {
/**
* 新增临时素材
*
* @param fileType
* @param filePath
* @return
* @throws Exception
*/
public JSONObject UploadMeida(String fileType, String filePath) throws Exception {
// 返回结果
String result = null;
File file = new File(filePath);
if (!file.exists() || !file.isFile()) {

throw new IOException("文件不存在");
}
WeChatMsgSend swx = new WeChatMsgSend();
String token = swx.getToken("ww6f36fa1463b963b0",
"1PF1i9ypGkMakBd-8nKw9kUeZkc95opSkm8MJGChSMw");
if (token == null) {
throw new IOException("未获取到token");
}
String uploadTempMaterial_url="https://qyapi.weixin.qq.com/cgi-bin/media/upload?access_token=ACCESS_TOKEN&type=TYPE";
uploadTempMaterial_url = uploadTempMaterial_url.replace("ACCESS_TOKEN", token).replace("TYPE", fileType);
URL url = new URL(uploadTempMaterial_url);
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setRequestMethod("POST");// 以POST方式提交表单
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);// POST方式不能使用缓存
// 设置请求头信息
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("Charset", "UTF-8");
// 设置边界
String BOUNDARY = "----------" + System.currentTimeMillis();
conn.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + BOUNDARY);
// 请求正文信息
// 第一部分
StringBuilder sb = new StringBuilder();
sb.append("--");// 必须多两条道
sb.append(BOUNDARY);
sb.append("\r\n");
sb.append("Content-Disposition: form-data;name=\"media\"; filename=\"" + file.getName() + "\"\r\n");
sb.append("Content-Type:application/octet-stream\r\n\r\n");


// 获得输出流
OutputStream out = new DataOutputStream(conn.getOutputStream());
// 输出表头
out.write(sb.toString().getBytes("UTF-8"));
// 文件正文部分
// 把文件以流的方式 推送道URL中
DataInputStream din = new DataInputStream(new FileInputStream(file));
int bytes = 0;
byte[] buffer = new byte[1024];
while ((bytes = din.read(buffer)) != -1) {
out.write(buffer, 0, bytes);
}
din.close();
// 结尾部分
byte[] foot = ("\r\n--" + BOUNDARY + "--\r\n").getBytes("UTF-8");// 定义数据最后分割线
out.write(foot);
out.flush();
out.close();
if (HttpsURLConnection.HTTP_OK == conn.getResponseCode()) {

StringBuffer strbuffer = null;
BufferedReader reader = null;
try {
strbuffer = new StringBuffer();
reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String lineString = null;
while ((lineString = reader.readLine()) != null) {
strbuffer.append(lineString);

}
if (result == null) {
result = strbuffer.toString();

}
} catch (IOException e) {

e.printStackTrace();
} finally {
if (reader != null) {
reader.close();
}
}

}
JSONObject jsonObject = JSONObject.parseObject(result);
return jsonObject;

}
}

五、测试类

import com.alibaba.fastjson.JSONObject;

import java.io.IOException;

public class Test {
public static void main(String[] args) {
UploadMeida uploadMeida = new UploadMeida();
String fileType = "file";
String filePath = "src/main/resources/excel/工资条.xls";
WeChatMsgSend swx = new WeChatMsgSend();
try {
String token = swx.getToken("你的corpID",
"你的Secret");
JSONObject jsonObject = uploadMeida.UploadMeida(fileType, filePath);
Object media_id = jsonObject.get("media_id");


String postdata = swx.createpostdata(
"你要发送的账户名", "file", 1000002, "media_id", media_id);
String resp = swx.post("utf-8", WeChatMsgSend.CONTENT_TYPE, (new WeChatUrlData()).getSendMessage_Url(), postdata, token);
System.out.println("获取到的toke n======>" + token);
System.out.println("请求数据======>" + postdata);
System.out.println("发送微信的响应数据======>" + resp);
System.err.println(media_id);

} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
}
