+title: 记一次Dubbo invoke命令的问题

+# 记一次Dubbo invoke命令的问题
+
+# 背景
+
+因为线上发生了一次死锁问题，导致数据没有正常写入，需要手动调用dubbo invoke重试。
+
+接口入参为 String, String, Object
+
+命令为：
+
+```java
+invoke xxService.xxMethod("123","321",{...})
+```
+
+愉快进入容器，开始执行，不出意外，意外就发生了
+
+```java
+Invalid json argument, cause: unclosed string : 
+```
+
+
+# 排查
+
+最开始以为是JSON格式有问题，开始排查格式，用了各种校验工具都没有发现问题
+
+举例格式如下：
+
+```json
+{
+    "class": "xxx",
+    "xx": "xxx",
+    "xxx": "xxx",
+    "xxxx": "xxx",
+    "xxx": "xxxx",
+    "xxxRequest": {
+        "xxxNo": "xxx",
+        "xxxName": "xx(XXX)x"
+    },
+    "xxxItemDataList": [
+        {
+            "xxx": "xxx",
+            "xxx": "xxx",
+            "class": "xxx.xxx.xxx.xxx"
+        }
+    ]
+}
+```
+
+因为接口的入参是一个父类，所以用class执行具体子类类型，
+
+list中同样也制定了类型
+
+用了各种工具校验，JSON都没有问题，最后跟代码发现，**是因为Json中的value有英文的括号，导致命令解析出现了问题，到括号就结束了解析**，实际到Dubbo中的JSON是
+
+```json
+{
+    "class": "xxx",
+    "xx": "xxx",
+    "xxx": "xxx",
+    "xxxx": "xxx",
+    "xxx": "xxxx",
+    "xxxRequest": {
+        "xxxNo": "xxx",
+        "xxxName": "xx(XXX
+```
+
+这可不就是JSON格式有误吗？
+
+# 代码解析
+
+dubbo分支切换到2.7.x
+
+全局搜`Invalid json argument`，找到代码
+
+ ![clipboard.png](https://static.lianglianglee.com/2024/03/Y018tCK.png)
+
+按照第一个英文括号解析的，导致整个命令被强制截断。
+
+再看一下最新代码 3.2的版本
+
+ ![clipboard.png](https://static.lianglianglee.com/2024/03/3k3JtCK.png)
+
+最新版已经修复了这个问题。
+
+
+# 总结
+
+当dubbo版本是2.7.x，使用invoke时，参数中不能有英文右括号
