填写的内容微信没有查询的接口，备案成功了才有一个查询备案详情的接口。 所以稳妥的做法是：需要一个表把备案提交的信息存起来。 例如： 提交备案这个表单的数据，用一个表的字段存起来。 [图片] 下次，要重复提交备案后，表单数据可以加载出来，用于回显数据。而不是一个一个字段地重填，效率太低了。

请大家留意这个文章的回复，我将源码也附上了，接口没有什么问题，大家没有完全理解https://developers.weixin.qq.com/community/develop/doc/0008ac553d49d02208504ad8664400

请留意这个文章，我已将自己的分享及源码附上， 接口完全没有问题 https://developers.weixin.qq.com/community/develop/doc/0008ac553d49d02208504ad8664400

最近我在开发小程序备案这块功能涉及到上传备案材料，我可以将自己的实现分享出来 。使用的是响应式编程。 先看接口层： @RequestMapping(value = {"/security_superadmin/mini/icp/media/upload"}, method = RequestMethod.POST) public Mono image_upload(@RequestPart("file") Mono filePartMono, @RequestParam(value="component_appid",required = true) String component_appid, @RequestParam(value="authorizer_appid",required = true) String authorizer_appid, @RequestHeader(value="admintoken", required = true) String token, @RequestHeader("Content-Length") long contentLength, @RequestParam(value="type",required = true) String type, @RequestParam(value="certificate_type",required = true) String certificate_type, @RequestParam(value="icp_order_field",required = true) String icp_order_field ) throws Throwable { return wechatPlatformService.uploadMediaFile( filePartMono, component_appid, authorizer_appid, type, certificate_type, icp_order_field).map(res -> res); } 再看服务层： public Mono uploadMediaFile(Mono filePartMono , String component_appid, String authorizer_appid, String type, String certificate_type, String icp_order_field) throws Throwable { return filePartMono.doOnNext(fp -> log.info("Receiving File:{}" ,fp.filename())).flatMap(filePart -> { PlatformGrant grant = null; try { grant = super.getApiToken(component_appid, authorizer_appid); } catch (Exception e) { return Mono.just(Response.error(e)); } String url = "https://api.weixin.qq.com/wxa/icp/upload_icp_media?access_token=" + grant.getAuthorizer_access_token(); log.info("---> url {}", url); log.info("---->go here <----"); File temFile = new File("/tmp"); if (!temFile.exists()) { temFile.mkdirs(); } File upFile = new File(temFile + "/" + UUID.randomUUID() + ".jpg"); if (!upFile.exists()) { try { upFile.createNewFile(); } catch (Exception e) { return Mono.just(Response.error("上传文件异常:" + e.getMessage())); } } filePart.transferTo(upFile); byte[] bytes = null; try { bytes = Files.readAllBytes(upFile.toPath()); } catch (Exception e) { return Mono.just(Response.error("上传文件异常:" + e.getMessage())); } HttpHeaders headers = new HttpHeaders(); headers.setContentType(MediaType.MULTIPART_FORM_DATA); HttpHeaders pictureHeader = new HttpHeaders(); pictureHeader.setContentDispositionFormData("file",upFile.getName()); pictureHeader.setContentType(MediaType.IMAGE_PNG); ByteArrayResource bar = new ByteArrayResource(bytes); HttpEntity picturePart = new HttpEntity<>(bar, pictureHeader); MultiValueMap multipartRequest = new LinkedMultiValueMap<>(); multipartRequest.add("media", picturePart); multipartRequest.add("type", type); multipartRequest.add("certificate_type", certificate_type); multipartRequest.add("icp_order_field", icp_order_field); HttpEntity entity = new HttpEntity(multipartRequest, headers); JSONObject json = restTemplate.postForObject(url, entity, JSONObject.class); log.info("--->上传备案媒体素材结果{}", json.toJSONString()); if (upFile.exists()){ upFile.delete(); log.info("---->删除文件<----"); } Integer errocode = json.getInteger("errcode"); if (0 == errocode.intValue()) { MiniMediaRecord record = new MiniMediaRecord(); record.setMedia_id(json.getString("media_id")); record.setType(type); record.setAuthorizer_appid(authorizer_appid); record.setComponent_appid(component_appid); record.setAuthorizer_appname(grant.getMuch_mini_name() != null ? grant.getMuch_mini_name() : ""); record.setCert_type(certificate_type); record.setSubmit_time(new Date()); record.setIcp_order_field(icp_order_field); miniMediaRecordRepository.save(record); } return Mono.just(Response.success("success")); }).then(Mono.just(Response.success("success"))); } 需要注意的是： 微信官方的这个接口不能以JSON格式提交参数，使用 restTemplate 需要 构造出一个 HttpEntity<ByteArrayResource> 对象。 HttpEntity picturePart = new HttpEntity<>(bar, pictureHeader); UI 界面： [图片] 响应结果： [图片] 希望有帮助。 欢迎加我微信：comeon_betty 来交流学习。

已经解决。 代商家获取小程序详情接口，在这分享一下： @RequestMapping(value = {"/qurey/minin/info"}, method = RequestMethod.POST) public JSONObject queryMiniNameStatus(@RequestBody JSONObject body) { try { return wechatPlatformService.queryMiniInfo(body); } catch (Exception e) { log.error(StackTool.error(e, 100)); return new JSONObject().fluentPut("resCode", Constants.KEY_OP_FAIL).fluentPut("resMsg", e.getMessage()); } } /** * 查询小程序名称设置状态 * * @param body * @return * @throws Exception * */ public JSONObject queryMiniInfo(JSONObject body) throws Exception { String component_appid = body.getString("component_appid");

charset=utf-8"); headers.setContentType(type); headers.add("Accept", MediaType.APPLICATION_XML.toString()); restTemplate.getMessageConverters().set(1, new StringHttpMessageConverter(StandardCharsets.UTF_8)); String url = "https://api.weixin.qq.com/cgi-bin/account/getaccountbasicinfo?access_token=" + grant.getAuthorizer_access_token(); body.remove("component_appid"); body.remove("authorizer_appid"); HttpEntity<JSONObject> formEntity = new HttpEntity<JSONObject>(body, headers);

return component_access_token; } 最后， 通过第三方平台来管理商家微信小程序，也可以由商家来自助管理。如：设置小程序图像、小程序介绍等信息。贴一张图片大家看看效果。微信的接口调用正确了还是非常稳定的。 之所以调用出错是没有使用商家的授权 authorizer_access_token [图片]
