## 使用方式
|
|||
|
|
### 上传文件：
|
|||
|
|
WEB页面的形式
|
|||
|
|
编辑一个html页面，代码如下：
|
|||
|
|
```html
|
|||
|
|
<!DOCTYPE html>
|
|||
|
|
<html lang="zh_CN">
|
|||
|
|
<head>
|
|||
|
|
<meta charset="UTF-8">
|
|||
|
|
<title>测试文件上传功能</title>
|
|||
|
|
</head>
|
|||
|
|
<body>
|
|||
|
|
<form action="http://192.168.0.40:9631/upload" method="post" enctype="multipart/form-data">
|
|||
|
|
<input type="file" name="file"/>
|
|||
|
|
<input type="submit" value="上传文件"/>
|
|||
|
|
</form>
|
|||
|
|
</body>
|
|||
|
|
</html>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
使用浏览器打开该页面，通过页面表单的形式上传文件，上传成功后会返回文件的唯一ID，返回的报文如下：
|
|||
|
|
```json
|
|||
|
|
{
|
|||
|
|
"success":true,
|
|||
|
|
"code":"000000",
|
|||
|
|
"message":"接口调用成功",
|
|||
|
|
"timestamp":1585132341906,
|
|||
|
|
"data":"5c2e20f0cfd04ba5a5cc86ed128c9564"
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
JAVA编码的形式
|
|||
|
|
引用Maven依赖：
|
|||
|
|
```xml
|
|||
|
|
<dependency>
|
|||
|
|
<groupId>net.northking.commons</groupId>
|
|||
|
|
<artifactId>nk-files-client</artifactId>
|
|||
|
|
<version>2.0.0-SNAPSHOT</version>
|
|||
|
|
</dependency>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
JAVA示例代码如下:
|
|||
|
|
```java
|
|||
|
|
String ipAddress = "192.168.0.40";
|
|||
|
|
int port = 9631;
|
|||
|
|
// File file = new File("F:\\工作笔记\\项目资料\\图片\\京北方云测试平台\\监控中心.png");
|
|||
|
|
File file = new File("F:\\软件\\GamingCenter_1.2.3.4_Mechrevo.zip");
|
|||
|
|
// 返回文件的唯一ID，此ID用于文件下载、查询等功能
|
|||
|
|
String fileId = NKFilesClient.uploadFile(ipAddress, port, file);
|
|||
|
|
if (fileId != null)
|
|||
|
|
{
|
|||
|
|
System.out.println("文件上传成功，文件ID：" + fileId);
|
|||
|
|
}
|
|||
|
|
|
