七牛云存储
在 DataCap 中目前已经支持七牛云,支持功能如下:
- 上传文件
- 预览&下载文件
- 删除文件
DataCap 使用配置¶
在 DataCap 中文件系统用于配置系统的缓冲以及临时文件的存储。修改 application.properties
文件如下内容:
datacap.fs.type=Qiniu
datacap.fs.access=
datacap.fs.secret=
datacap.fs.endpoint=
datacap.fs.bucket=
datacap.fs.type
: 文件系统的类型只能是 Qiniudatacap.fs.access
: 七牛云的 AccessKeydatacap.fs.secret
: 七牛云的 SecretKeydatacap.fs.endpoint
: 七牛云的 Endpointdatacap.fs.bucket
: 七牛云的存储桶名称,如datacap
依赖使用方式¶
该插件支持第三方依赖方式引入,引入依赖如下:
<dependency>
<groupId>io.edurt.datacap</groupId>
<artifactId>datacap-fs-qiniu</artifactId>
<version>${VERSION}</version>
</dependency>
使用代码如下:
package io.edurt.datacap.fs.qiniu
import com.google.inject.Guice
import com.google.inject.Injector
import com.google.inject.Key
import com.google.inject.TypeLiteral
import io.edurt.datacap.fs.Fs
import io.edurt.datacap.fs.FsManager
import io.edurt.datacap.fs.FsRequest
import org.junit.Before
import org.junit.Test
import org.slf4j.LoggerFactory
import java.io.BufferedReader
import java.io.FileInputStream
import java.io.IOException
import java.io.InputStreamReader
import java.nio.charset.StandardCharsets
import kotlin.test.assertTrue
class QiniuFsTest {
private val log = LoggerFactory.getLogger(QiniuFsTest::class.java)
private val name = "Qiniu"
private var request = FsRequest()
private var injector: Injector? = null
@Before
fun before() {
request.access = System.getProperty("access")
request.secret = System.getProperty("secret")
request.bucket = System.getProperty("bucket")
request.fileName = "IOUtilsTest.kt"
request.endpoint = System.getProperty("endpoint")
injector = Guice.createInjector(FsManager())
}
@Test
fun writer() {
val plugins: Set<Fs?>? = injector?.getInstance(Key.get(object : TypeLiteral<Set<Fs?>?>() {}))
val plugin: Fs? = plugins?.first { v -> v?.name().equals(name) }
val stream = FileInputStream("src/test/kotlin/io/edurt/datacap/fs/qiniu/IOUtilsTest.kt")
request.stream = stream
val response = plugin !!.writer(request)
assertTrue(response.isSuccessful)
}
@Test
fun reader() {
val plugins: Set<Fs?>? = injector?.getInstance(Key.get(object : TypeLiteral<Set<Fs?>?>() {}))
val plugin: Fs? = plugins?.first { v -> v?.name().equals(name) }
val response = plugin !!.reader(request)
assertTrue(response.isSuccessful)
try {
BufferedReader(InputStreamReader(response.context, StandardCharsets.UTF_8)).use { reader ->
var line: String?
while ((reader.readLine().also { line = it }) != null) {
log.info(line)
}
}
}
catch (e: IOException) {
log.error("Reader error", e)
}
}
@Test
fun testDelete() {
val plugins: Set<Fs?>? = injector?.getInstance(Key.get(object : TypeLiteral<Set<Fs?>?>() {}))
val plugin: Fs? = plugins?.first { v -> v?.name().equals(name) }
val response = plugin !!.delete(request)
assertTrue(response.isSuccessful)
}
}
