房源服务
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
借助属性服务,您可以将简单数据以键值对的形式存储在以下范围内:一个脚本、一个脚本用户或使用插件的一个文档。它通常用于存储开发者配置或用户偏好设置。属性绝不会在脚本之间共享。

PropertiesService
全局对象提供三种方法,每种方法都会返回类似的 Properties
对象,但具有不同的访问权限,如下表所示:
Properties 服务以键值对的形式将所有数据存储为字符串。系统会自动将非字符串的数据类型(包括保存的对象中包含的方法)转换为字符串。
保存数据
如需保存单个值,请调用相应存储区的 Properties.setProperty(key,
value)
方法,如以下示例所示:
如需批量保存数据,请将键值对的映射传递给 Properties.setProperties(properties)
。参数中对象的每个键值对都存储为单独的属性:
读取数据
如需检索之前保存的单个值,请调用 Properties.getProperty(key)
:
如需检索当前属性存储区中的所有值,请调用 Properties.getProperties()
:
修改数据
方法 getProperty()
和 getProperties()
返回的是存储数据的副本,而不是实时视图,因此更改返回的对象不会更新属性存储区中的值。如需更新商店中的数据,只需再次保存即可:
删除数据
如需删除单个值,请调用 Properties.deleteProperty(key)
:
如需删除当前商店中的所有属性,请调用 Properties.deleteAllProperties()
:
手动管理脚本属性
您可以在项目设置页面中手动添加最多 50 个自定义属性,以键值对形式的字符串表示。如需添加超过 50 个属性,您需要使用保存数据中介绍的方法以编程方式添加这些属性。从项目设置页面设置脚本属性时,您无法引用脚本变量。

It is\ntypically used to store developer configuration or user preferences. Properties\nare never shared between scripts.\n\nTo view the daily quotas and storage limits for the Properties service, see\n[Quotas for Google Services](/apps-script/guides/services/quotas).\n\nComparison of property stores\n-----------------------------\n\nThe\n[`PropertiesService`](/apps-script/reference/properties/properties-service)\nglobal object offers three methods, each of which returns a similar\n[`Properties`](/apps-script/reference/properties/properties)\nobject but with different access rights, as shown in the following table:\n\n| | Script Properties | User Properties | Document Properties |\n|--------------------|-----------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------|\n| Method to access | [getScriptProperties()](/apps-script/reference/properties/properties-service#getScriptProperties()) | [getUserProperties()](/apps-script/reference/properties/properties-service#getUserProperties()) | [getDocumentProperties()](/apps-script/reference/properties/properties-service#getDocumentProperties()) |\n| Data shared among | All users of a script, add-on, or web app | The current user of a script, add-on, or web app | All users of an add-on in the open document |\n| Typically used for | App-wide configuration data, like the username and password for the developer's external database | User-specific settings, like metric or imperial units | Document-specific data, like the source URL for an embedded chart |\n\nData format\n-----------\n\nThe Properties service stores all data as strings in key-value pairs. Data types\nthat are not already strings are automatically converted to strings, including\nmethods contained within saved objects.\n\nSaving data\n-----------\n\nTo save a single value, call the method [`Properties.setProperty(key,\nvalue)`](/apps-script/reference/properties/properties#setProperty(String,String))\nof the appropriate store, as shown in the following example: \nservice/propertyService.gs \n[View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/service/propertyService.gs) \n\n```javascript\ntry {\n // Set a property in each of the three property stores.\n const scriptProperties = PropertiesService.getScriptProperties();\n const userProperties = PropertiesService.getUserProperties();\n const documentProperties = PropertiesService.getDocumentProperties();\n\n scriptProperties.setProperty('SERVER_URL', 'http://www.example.com/');\n userProperties.setProperty('DISPLAY_UNITS', 'metric');\n documentProperties.setProperty('SOURCE_DATA_ID',\n '1j3GgabZvXUF177W0Zs_2v--H6SPCQb4pmZ6HsTZYT5k');\n} catch (err) {\n // TODO (developer) - Handle exception\n console.log('Failed with error %s', err.message);\n}\n```\n\nTo save data in bulk, pass a map of key-value pairs to\n[`Properties.setProperties(properties)`](/apps-script/reference/properties/properties#setProperties(Object)).\nEach key-value pair of the object in the parameter is stored as a separate\nproperty: \nservice/propertyService.gs \n[View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/service/propertyService.gs) \n\n```javascript\ntry {\n // Set multiple script properties in one call.\n const scriptProperties = PropertiesService.getScriptProperties();\n scriptProperties.setProperties({\n 'cow': 'moo',\n 'sheep': 'baa',\n 'chicken': 'cluck'\n });\n} catch (err) {\n // TODO (developer) - Handle exception\n console.log('Failed with error %s', err.message);\n}\n```\n\nReading data\n------------\n\nTo retrieve a single value that you have previously saved, call\n[`Properties.getProperty(key)`](/apps-script/reference/properties/properties#getProperty(String)): \nservice/propertyService.gs \n[View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/service/propertyService.gs) \n\n```javascript\ntry {\n // Get the value for the user property 'DISPLAY_UNITS'.\n const userProperties = PropertiesService.getUserProperties();\n const units = userProperties.getProperty('DISPLAY_UNITS');\n console.log('values of units %s', units);\n} catch (err) {\n // TODO (developer) - Handle exception\n console.log('Failed with error %s', err.message);\n}\n```\n\nTo retrieve all values in the current property store, call\n[`Properties.getProperties()`](/apps-script/reference/properties/properties#getProperties()): \nservice/propertyService.gs \n[View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/service/propertyService.gs) \n\n```javascript\ntry {\n // Get multiple script properties in one call, then log them all.\n const scriptProperties = PropertiesService.getScriptProperties();\n const data = scriptProperties.getProperties();\n for (const key in data) {\n console.log('Key: %s, Value: %s', key, data[key]);\n }\n} catch (err) {\n // TODO (developer) - Handle exception\n console.log('Failed with error %s', err.message);\n}\n```\n\nModifying data\n--------------\n\nThe methods `getProperty()` and `getProperties()` return a copy of the stored\ndata, not a live view, so changing the returned object will not update the value\nin the property store. To update the data in the store, simply save it again: \nservice/propertyService.gs \n[View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/service/propertyService.gs) \n\n```javascript\ntry {\n // Change the unit type in the user property 'DISPLAY_UNITS'.\n const userProperties = PropertiesService.getUserProperties();\n let units = userProperties.getProperty('DISPLAY_UNITS');\n units = 'imperial'; // Only changes local value, not stored value.\n userProperties.setProperty('DISPLAY_UNITS', units); // Updates stored value.\n} catch (err) {\n // TODO (developer) - Handle exception\n console.log('Failed with error %s', err.message);\n}\n```\n\nDeleting data\n-------------\n\nTo delete a single value, call\n[`Properties.deleteProperty(key)`](/apps-script/reference/properties/properties#deleteProperty(String)): \nservice/propertyService.gs \n[View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/service/propertyService.gs) \n\n```javascript\ntry {\n // Delete the user property 'DISPLAY_UNITS'.\n const userProperties = PropertiesService.getUserProperties();\n userProperties.deleteProperty('DISPLAY_UNITS');\n} catch (err) {\n // TODO (developer) - Handle exception\n console.log('Failed with error %s', err.message);\n}\n```\n\nTo delete all properties in the current store, call\n[`Properties.deleteAllProperties()`](/apps-script/reference/properties/properties#deleteAllProperties()): \nservice/propertyService.gs \n[View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/service/propertyService.gs) \n\n```javascript\ntry {\n // Get user properties in the current script.\n const userProperties = PropertiesService.getUserProperties();\n // Delete all user properties in the current script.\n userProperties.deleteAllProperties();\n} catch (err) {\n // TODO (developer) - Handle exception\n console.log('Failed with error %s', err.message);\n}\n```\n\nManage script properties manually\n---------------------------------\n\nYou can manually add up to fifty custom properties, as strings in key-value\npairs, from the project settings page. To add more than fifty properties, you\nneed to add them programmatically using the methods described above in\n[Saving data](#saving-data).\nWhen you set script properties from the project settings page, you can't\nreference script variables.\n\n### Add script properties\n\n1. Open your Apps Script project.\n2. At the left, click **Project Settings** .\n3. To add the first property, under **Script Properties** click **Add script property**.\n4. To add second and subsequent properties, under **Script Properties** click **Edit script properties** \\\u003e **Add script property**.\n5. For **Property**, enter the key name.\n6. For **Value**, enter the value for the key.\n7. (Optional) To add more properties, click **Add script property**.\n8. Click **Save script properties**.\n\n### Edit script properties\n\n1. Open your Apps Script project.\n2. At the left, click **Project Settings** .\n3. Under **Script Properties** , click **Edit script properties**.\n4.
