@PostMapping(value = "/inventorySelect") public void checkInAndOutOfTheLibrary(@RequestBody BlcInOutStoreResponse BlcInOutStoreResponse) { checkInAndOutOfTheLibraryService.checkInAndOutSelect(BlcInOutStoreResponse); }完善以上代码使后端成功接收XML数据，并解决org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/xml;charset=UTF-8' not supported问题

可以使用`consumes`属性来指定接收的请求类型为XML，同时使用`produces`属性来指定返回的响应类型为JSON，代码如下所示：

@PostMapping(value = "/inventorySelect", consumes = MediaType.APPLICATION_XML_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
public void checkInAndOutOfTheLibrary(@RequestBody BlcInOutStoreResponse BlcInOutStoreResponse) {
    checkInAndOutOfTheLibraryService.checkInAndOutSelect(BlcInOutStoreResponse);
}

这样就可以让后端成功接收XML数据，并且解决`HttpMediaTypeNotSupportedException`异常问题。注意需要导入`MediaType`类。

将下面的java代码转python @Controller public class IndexControlle { SimpleDateFormat df = new SimpleDateFormat( pattern: "yyy-MM-dd HH:mm:ss"); private final static Logger logger = LoggerFacstory.getLogger(IndexControlle.class) @RequestMapping("/index") @ResponseBody public String index() { logger.info("hello world» » » "); return "hello world》》》"; //关键数据订阅返回响应 @PostMapping(value = "/jsoni", produces = "application/json; charset=UTF-8") @ResponseBody public void json1(@RequestBody String content) throwsUnsupportedEncodingException { logger.info("json1关键数据订阅返回响应》》》"+content); @PostMapping(value = "/json2", produces = "applicatioon/json; charset=utf-8") @ResponseBody public void hello3(@RequestBody String content) { logger.info("json2响应数据》》"+content); } @PostMapping("/map10") @ResponseBody public void hello6(@RequestBody Map<String, Oboject> params){logger.info("map10响应数据》》》"+params); } //最早版本用map接收的 @PostMapping("/map1") @ResponseBody public void hello(@RequestParam Map<String, Object> params) {logger.info("map1响应数据》》"+params); @PostMapping("/map2") @ResponseBody public void hello2(@RequestParam Map<String, Object> pparams){logger.info("map2响应数据》》"+params); }

下面是将Java代码转换成Python的结果：

from datetime import datetime
import logging

from flask import Flask, request, jsonify

app = Flask(__name__)

df = "%Y-%m-%d %H:%M:%S"
logger = logging.getLogger(__name__)

@app.route('/index')
def index():
    logger.info("hello world")
    return "hello world"

@app.route('/json1', methods=['POST'])
def json1():
    content = request.get_json()
    logger.info("json1关键数据订阅返回响应》》》" + str(content))
    return jsonify(success=True)

@app.route('/json2', methods=['POST'])
def json2():
    content = request.get_json()
    logger.info("json2响应数据》》》" + str(content))
    return jsonify(success=True)

@app.route('/map10', methods=['POST'])
def map10():
    params = request.get_json()
    logger.info("map10响应数据》》》" + str(params))
    return jsonify(success=True)

@app.route('/map1', methods=['POST'])
def map1():
    params = request.form.to_dict()
    logger.info("map1响应数据》》》" + str(params))
    return jsonify(success=True)

@app.route('/map2', methods=['POST'])
def map2():
    params = request.form.to_dict()
    logger.info("map2响应数据》》》" + str(params))
    return jsonify(success=True)

if __name__ == '__main__':
    app.run()

需要注意的是，Python中的时间格式化和Java有所不同，需要根据具体需求进行转换。此外，Python中的日志模块也有所不同，需要根据具体需求进行调整。此外，Python中使用`request.get_json()`来获取POST请求中的JSON数据，使用`request.form.to_dict()`来获取POST请求中的表单数据。

@PostMapping("/appUpdate") @ApiOperation(value = "获取版本更新") public Response<AppUpdateResponseVO> appUpdate(@RequestBody @Valid Request<AppUpdateRequestVO> request) { log.info("appUpdate request {}", JacksonUtils.toJson(request)); AppUpdateRequestDTO appUpdateRequestDto = WalletVoMapper.INSTANCE.toDto(request.getParam()); AppUpdateResponseDTO appUpdateByVersion = appUpdateService.getAppUpdateByVersion(appUpdateRequestDto, request.getAppVersion(), request.getAppType(), request.getPlatform(),request.getClientIp()); AppUpdateResponseVO appUpdateResponseVo = WalletVoMapper.INSTANCE.toVo(appUpdateByVersion); PlatformEnum platform = request.getPlatform() == PlatformEnum.WEB_H5 ? request.getParam().getPlatform() : request.getPlatform(); boolean downloadUrlStatus = SpringUtil.getProperty("s3.download.status", boolean.class, true); if (downloadUrlStatus) { String downloadUrlS3 = SpringUtil.getProperty(MessageFormat.format("{0}.s3.download.url", platform.name().toLowerCase())); log.info("appUpdate downloadUrlS3 {}", downloadUrlS3); appUpdateResponseVo.setDownloadUrl(downloadUrlS3); } log.info("appUpdate response {}", JacksonUtils.toJson(appUpdateResponseVo)); return Response.succeed(appUpdateResponseVo); }增加一个下载次数限制 用代码展示

可以在 `AppUpdateService` 中添加一个方法，记录每个版本的下载次数，例如：

public void recordDownload(String version) {
    // TODO: 将版本号为 version 的下载次数加一，可以使用 Redis 或数据库实现计数器
}

然后在 `appUpdate` 方法中，在设置下载链接之前调用该方法来记录下载次数，例如：

if (downloadUrlStatus) {
    String downloadUrlS3 = SpringUtil.getProperty(MessageFormat.format("{0}.s3.download.url", platform.name().toLowerCase()));
    log.info("appUpdate downloadUrlS3 {}", downloadUrlS3);
    appUpdateResponseVo.setDownloadUrl(downloadUrlS3);
    appUpdateService.recordDownload(appUpdateResponseVo.getVersion());
}

这样就可以在下载链接被返回时记录下载次数了。同时，可以在 `recordDownload` 方法中添加一些逻辑来限制下载次数，例如：

public void recordDownload(String version) {
    // TODO: 将版本号为 version 的下载次数加一，可以使用 Redis 或数据库实现计数器
    int downloadCount = getDownloadCount(version);
    if (downloadCount >= MAX_DOWNLOAD_COUNT) {
        throw new RuntimeException("该版本下载次数已达上限");
    }
}

这样就实现了一个简单的下载次数限制功能。
