使用命令行 下载微信支付APIv3证书失败是什么原因？
使用CertificateDownloader工具命令行执行，报错如下 download failed,resp code=404,body={"code":"RESOURCE_NOT_EXISTS","message":"证书不存在"} java.io.IOException: request failed at com.elias.CertificateDownloader.downloadCertificate(CertificateDownloader.java:104) at com.elias.CertificateDownloader.run(CertificateDownloader.java:65) at picocli.CommandLine.executeUserObject(CommandLine.java:1939) at picocli.CommandLine.access$1300(CommandLine.java:145) at picocli.CommandLine$RunLast.executeUserObjectOfLastSubcommandWithSameParent(CommandLine.java:2358) at picocli.CommandLine$RunLast.handle(CommandLine.java:2352) at picocli.CommandLine$RunLast.handle(CommandLine.java:2314) at picocli.CommandLine$AbstractParseResultHandler.handleParseResult(CommandLine.java:2172) at picocli.CommandLine.parseWithHandlers(CommandLine.java:2559) at picocli.CommandLine.run(CommandLine.java:3017) at picocli.CommandLine.run(CommandLine.java:2954) at com.elias.CertificateDownloader.main(CertificateDownloader.java:153) 紧急求助！折腾2天了。命令行参数都是商户号后台获取的，参数应该不会错
