+
+在生成的 `harmony-configs` 目录找到文件 `harmony-configs/build-profile.json5` 修改里面的 `app.signingConfigs`，具体格式如下：
+
+```js
+{
+	"app": {
+		"signingConfigs": [
+			{
+				"name": "default",
+				"type": "HarmonyOS",
+				"material": {
+					"storePassword": "xxxxxx",
+					"certpath": "D:/鸿蒙调试证书/xxx.cer",
+					"keyAlias": "别名",
+					"keyPassword": "xxxxxx",
+					"profile": "D:/鸿蒙调试证书/xxx.p7b",
+					"signAlg": "SHA256withECDSA",
+					"storeFile": "D:/鸿蒙调试证书/.p12"
+				}
+			},
+			{
+				"name": "release",
+				"type": "HarmonyOS",
+				"material": {
+					"storePassword": "xxxxxx",
+					"certpath": "D:/鸿蒙发布证书/xxx.cer",
+					"keyAlias": "别名",
+					"keyPassword": "xxxxxx",
+					"profile": "D:/鸿蒙发布证书/xxx.p7b",
+					"signAlg": "SHA256withECDSA",
+					"storeFile": "D:/鸿蒙发布证书/.p12"
+				}
+			}
+		],
+		"products": [
+			{
+				"name": "default",
+				"signingConfig": "default",
+				"compatibleSdkVersion": "5.0.0(12)",
+				"runtimeOS": "HarmonyOS",
+			},
+			{
+				"name": "release",
+				"signingConfig": "release",
+				"compatibleSdkVersion": "5.0.0(12)",
+				"runtimeOS": "HarmonyOS",
+			}
+		],
+		"buildModeSet": [
+			{
+				"name": "debug",
+			},
+			{
+				"name": "release"
+			}
+		]
+	},
+	"modules": [
+		{
+			"name": "entry",
+			"srcPath": "./entry",
+			"targets": [
+				{
+					"name": "default",
+					"applyToProducts": [
+						"default",
+						"release"
+					]
+				}
+			]
+		}
+	]
+}
+```
+
+配置完签名后，再次点击【发行】- 【App-Harmony-本地打包】即可得到已签名的 `.app` 安装包文件
+
+最后参考鸿蒙官方文档发布鸿蒙应用，详见[文档](https://developer.huawei.com/consumer/cn/doc/app/agc-help-releaseharmony-0000001933963166)
