# API数据源使用示例
|
|
|
|
|
|
|
|
## 调用示例代码
|
|
|
|
|
|
|
|
### 开启API数据源
|
|
|
|
|
|
|
|
```java
|
|
|
|
Authentication authentication = new Authentication("#key", "#secret");
|
|
|
|
DatasourceOperation operation = new DatasourceOperation(authentication);
|
|
|
|
operation.open();
|
|
|
|
```
|
|
|
|
|
|
|
|
在开启后,可以在企业数据的"数据导入"菜单看到如下图所示的API数据源入口
|
|
|
|
![api_datasource](/screenshots/api_datasource.png)
|
|
|
|
|
|
|
|
### 创建表
|
|
|
|
|
|
|
|
```java
|
|
|
|
Authentication authentication = new Authentication("#key", "#secret");
|
|
|
|
DatasourceOperation operation = new DatasourceOperation(authentication);
|
|
|
|
// // 创建表并返回表id
|
|
|
|
String tableId = operation.createTable("HelloTable");
|
|
|
|
```
|
|
|
|
|
|
|
|
### 更新表数据
|
|
|
|
|
|
|
|
```java
|
|
|
|
Authentication authentication = new Authentication("#key", "#secret");
|
|
|
|
DatasourceOperation operation = new DatasourceOperation(authentication);
|
|
|
|
// 创建表并返回表id
|
|
|
|
String tableId = "上一步获取到表id";
|
|
|
|
// 获取给该表提供数据的文件的上传地址
|
|
|
|
String fileUploadUrl = operation.requestUploadUrl(tableId);
|
|
|
|
// 将数据文件上传
|
|
|
|
HttpKits.upload(fileUploadUrl, new File(System.getProperty("user.dir") + "/data/地区数据分析.csv"));
|
|
|
|
// 标记该表的数据已经上传完成
|
|
|
|
operation.markAsFinish(tableId);
|
|
|
|
```
|
|
|
|
|
|
|
|
在调用了上述代码后,就可以在API数据源页面看到新增的表和其数据了,这时就可以和其他数据源表一样,添加到项目中使用了:

|
|
|
|
|
|
|
|
|
|
|
|
### 删除表(暂未实现)
|
|
|
|
```java
|
|
|
|
Authentication authentication = new Authentication("#key", "#secret");
|
|
|
|
DatasourceOperation operation = new DatasourceOperation(authentication);
|
|
|
|
String tableId = "#待删除的表id";
|
|
|
|
operation.deleteTable(tableId);
|
|
|
|
```
|
|
|
|
|
|
|
|
### 删除所有表(暂未实现)
|
|
|
|
```java
|
|
|
|
Authentication authentication = new Authentication("#key", "#secret");
|
|
|
|
DatasourceOperation operation = new DatasourceOperation(authentication);
|
|
|
|
operation.reset();
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
