这两天在网上看了其他的方法,也调试了一些,然后自己整理了一下,方便自己学习,也方便大家使用。
调用接口
1、java调用上传图片接口
public final static String IMAGE = "https://api.weixin.qq.com/cgi-bin/media/uploadimg?access_token=ACCESS_TOKEN"; public static String uploadimg(MultipartFile file ) { CloseableHttpClient client = HttpClients.createDefault(); // 创建httppost String requestUrl = IMAGE.replace("ACCESS_TOKEN", access_token);//替换调access_token HttpPost post = new HttpPost(requestUrl); RequestConfig config = RequestConfig.custom().setSocketTimeout(30000).setConnectTimeout(20000).build(); post.setConfig(config); File f = null; try { f = new File(file.getOriginalFilename()); inputStreamToFile(file.getInputStream(),f); FileUtils.copyInputStreamToFile(file.getInputStream(), f); } catch (IOException e) { e.printStackTrace(); } String name = f.getName(); FileBody fileBody = new FileBody(f, ContentType.DEFAULT_BINARY,name); String filename = fileBody.getFilename(); long contentLength = fileBody.getContentLength(); ContentType contentType = fileBody.getContentType(); MultipartEntityBuilder builder = MultipartEntityBuilder.create(); builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE); builder.addPart("media", fileBody); // 相当于 <input type="file" class="file" name="file">,匹配@RequestParam("file") // .addPart()可以设置模拟浏览器<input/>的表单提交 HttpEntity entity = builder.build(); post.setEntity(entity); String result = ""; try { CloseableHttpResponse e = client.execute(post); HttpEntity resEntity = e.getEntity(); if(entity != null) { result = EntityUtils.toString(resEntity); System.out.println("response content:" + result); } } catch (IOException var10) { System.out.println("请求解析验证码io异常 "+var10); //logger.error("请求解析验证码io异常",var10); var10.printStackTrace(); } return result; } public static void inputStreamToFile(InputStream ins, File file) { try { OutputStream os = new FileOutputStream(file); int bytesRead = 0; byte[] buffer = new byte[8192]; while ((bytesRead = ins.read(buffer, 0, 8192)) != -1) { os.write(buffer, 0, bytesRead); } os.close(); ins.close(); } catch (Exception e) { e.printStackTrace(); } }
2、新增永久图片素材
只需要修改 requestUrl
public final static String ADD_MATERIAL_IMAGE = "https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=ACCESS_TOKEN&type=TYPE";
3、新增永久视频素材
public final static String ADD_MATERIAL_IMAGE = "https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=ACCESS_TOKEN&type=TYPE"; /** * 上传永久素材(除 图文) * @param file * @param type * @param title type为video时需要,其他类型设null * @param introduction type为video时需要,其他类型设null * @return {"media_id":MEDIA_ID,"url":URL} */ public static String uploadPermanentMaterial(File file, String type, String title, String introduction) { String url = ADD_MATERIAL_IMAGE.replace("ACCESS_TOKEN", access_token).replace("TYPE", type);// 替换调access_token String result = null; try { URL uploadURL = new URL(url); HttpURLConnection conn = (HttpURLConnection) uploadURL.openConnection(); conn.setConnectTimeout(5000); conn.setReadTimeout(30000); conn.setDoOutput(true); conn.setDoInput(true); conn.setUseCaches(false); conn.setRequestMethod("POST"); conn.setRequestProperty("Connection", "Keep-Alive"); conn.setRequestProperty("Cache-Control", "no-cache"); String boundary = "-----------------------------" + System.currentTimeMillis(); conn.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary); OutputStream output = conn.getOutputStream(); output.write(("--" + boundary + " ").getBytes()); output.write(String.format("Content-Disposition: form-data; name="media"; filename="%s" ", file.getName()).getBytes()); output.write("Content-Type: video/mp4 ".getBytes()); byte[] data = new byte[1024]; int len = 0; FileInputStream input = new FileInputStream(file); while ((len = input.read(data)) > -1) { output.write(data, 0, len); } /*对类型为video的素材进行特殊处理*/ if ("video".equals(type)) { output.write(("--" + boundary + " ").getBytes()); output.write("Content-Disposition: form-data; name="description"; ".getBytes()); output.write(String.format("{"title":"%s", "introduction":"%s"}", title, introduction).getBytes()); } output.write((" --" + boundary + "-- ").getBytes()); output.flush(); output.close(); input.close(); InputStream resp = conn.getInputStream(); StringBuffer sb = new StringBuffer(); while ((len = resp.read(data)) > -1) sb.append(new String(data, 0, len, "utf-8")); resp.close(); result = sb.toString(); } catch (IOException e) { //.... } return result; }
上传视频的这个方法也可以上传其他素材。
4、上传永久图文素材
首先考虑传值,官方的示例
{ "articles": [{ "title": TITLE, "thumb_media_id": THUMB_MEDIA_ID, "author": AUTHOR, "digest": DIGEST, "show_cover_pic": SHOW_COVER_PIC(0 / 1), "content": CONTENT, "content_source_url": CONTENT_SOURCE_URL, "need_open_comment":1, "only_fans_can_comment":1 }, //若新增的是多图文素材,则此处应还有几段articles结构 ] }
1、直接put json,下面是一个简单的例子。这样很容易完成示例
//{ "tag":{ "id":134,//标签id "name":"广东" } } JSONObject json1 = new JSONObject(); json1.put("name", "广东"); JSONObject json = new JSONObject(); json.put("tag", json1);
2、使用实体类,可以参数与json转换
/*获取素材列表参数实体类**/ public class AddNewsParam { private Articles [] articles; public class Articles { private String title;// 图文消息的标题 private String thumb_media_id;// 图文消息的封面图片素材id(必须是永久mediaID) private String author;// 作者 private String digest;// 图文消息的摘要,仅有单图文消息才有摘要,多图文此处为空 private Integer show_cover_pic;// 是否显示封面,0为false,即不显示,1为true,即显示 private String content;// 图文消息的具体内容,支持HTML标签,必须少于2万字符,小于1M,且此处会去除JS private String content_source_url;// 图文消息的原文地址,即点击“阅读原文”后的URL private Integer need_open_comment;// 图文页的URL,或者,当获取的列表是图片素材列表时,该字段是图片的URL private Integer only_fans_can_comment;// Uint32 是否粉丝才可评论,0所有人可评论,1粉丝才可评论 public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public String getThumb_media_id() { return thumb_media_id; } public void setThumb_media_id(String thumb_media_id) { this.thumb_media_id = thumb_media_id; } public String getAuthor() { return author; } public void setAuthor(String author) { this.author = author; } public String getDigest() { return digest; } public void setDigest(String digest) { this.digest = digest; } public Integer getShow_cover_pic() { return show_cover_pic; } public void setShow_cover_pic(Integer show_cover_pic) { this.show_cover_pic = show_cover_pic; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } public String getContent_source_url() { return content_source_url; } public void setContent_source_url(String content_source_url) { this.content_source_url = content_source_url; } public Integer getNeed_open_comment() { return need_open_comment; } public void setNeed_open_comment(Integer need_open_comment) { this.need_open_comment = need_open_comment; } public Integer getOnly_fans_can_comment() { return only_fans_can_comment; } public void setOnly_fans_can_comment(Integer only_fans_can_comment) { this.only_fans_can_comment = only_fans_can_comment; } } public Articles[] getArticles() { return articles; } public void setArticles(Articles[] articles) { this.articles = articles; } }
调用方法
/**上传图文素材 * @param accessToken * @return */ public static String addNews(String accessToken,AddNewsParam entity) { String result = null; String requestUrl = ADD_NEWS.replace("ACCESS_TOKEN", accessToken);//替换调access_token String outputStr ; JSONObject jsonObject = new JSONObject(); jsonObject = JSONObject.fromObject(entity); outputStr = jsonObject.toString();//将参数对象转换成json字符串 System.out.println(outputStr); jsonObject = httpsRequest(requestUrl, "POST", outputStr); //发送https请求(请求的路径,方式,所携带的参数) // 如果请求成功 if (null != jsonObject) { try { result = jsonObject.toString(); System.out.println(jsonObject); } catch (JSONException e) { accessToken = null; // 获取Material失败 result = (jsonObject.getInt("errcode")+","+jsonObject.getString("errmsg")); System.out.println("jsonObject.getInt(errcode)"+jsonObject.getInt("errcode")); System.out.println("jsonObject.getString(errmsg)"+jsonObject.getString("errmsg")); log.error("获取Material失败 errcode:{} errmsg:{}", jsonObject.getInt("errcode"), jsonObject.getString("errmsg")); } } return result; }
如果用第一种方式,直接传json,修改一下代码就可以使用。
