通过 Java/Python 将 dto 传递给 Google Apps 脚本方法

Question

我在应用程序脚本中编写了一个原型函数

function replaceWithObjects(documentId, objectsArray) {
  Logger.log("replaceWithObjects call: documentId:" + documentId + " objectsArray:" + objectsArray);
  var body = DocumentApp.openById(documentId).getBody();
  var length = objectsArray.length;
  for (i = 0; i < length; i++) {
    var toReplace = '#{' + objectsArray[i].toReplace + '}';
    var targetText = objectsArray[i].targetText;
    Logger.log("To replace: " + toReplace + " with: " + targetText);
    body.replaceText(toReplace, targetText);
  } 
}

使用 python 我能够传递这些 objectsArray 的列表，如下所示：

a_replace = {"toReplace": "A", "targetText": "object_a"};
b_replace = {"toReplace": "B", "targetText": "object_b"};
c_replace = {"toReplace": "C", "targetText": "object_c"};
request = {"function": "replaceWithObjects", "parameters": [poc_doc_id, [a_replace,b_replace,c_replace]]}

但是，对于 Java 及其 ExecutionRequest 对象，在使用其 setParameters 方法设置对象列表时，我无法做到这一点

private static ExecutionRequest getExecutionRequest(String function, List<Object> parameters) {
        ExecutionRequest executionRequest = new ExecutionRequest().setFunction(function);
        if (parameters != null && !parameters.isEmpty()) {
            executionRequest.setParameters(parameters);
        }
        return executionRequest;
    }

我尝试将列表中的对象作为 json 字符串传递，或者实现 Serializable 类：

public static class Replace extends Object implements Serializable {
            public String toReplace;
            public String targetText;
            public Replace(String toReplace, String targetText) {
                this.toReplace = toReplace;
                this.targetText = targetText;
            }

            public String getToReplace() {
                return toReplace;
            }

            public String getTargetText() {
                return targetText;
            }
        }

但无济于事。 python 使用能够让 .toReplace 和 .targetText 提供正确的值，但 java 方面仍然是一个挑战。文档建议：“只能传递和返回字符串、数组、对象、数字和布尔值等基本类型。”并且无法找到传递对象的java示例。如果支持对象传递，就像 python 概念证明可以做的那样，我在 Java 方面缺少什么？

长话短说，将对象直接转换为哈希图节省了时间：

public Object asHashMap() {
            HashMap<String, String> hashMap = new HashMap<>();
            hashMap.put("toReplace", toReplace);
            hashMap.put("targetText", targetText);
            return hashMap;
        }
