七牛对象管理

基于 qiniu-apis 提供针对七牛对象的管理功能（同时提供阻塞客户端和异步客户端，异步客户端则需要启用 async 功能），主要负责七牛对象的列举和操作。

代码示例

对象元信息获取

阻塞代码示例

use qiniu_objects_manager::{apis::credential::Credential, ObjectsManager};

let credential = Credential::new("abcdefghklmnopq", "1234567890");
let object_manager = ObjectsManager::builder(credential).build();
let bucket = object_manager.bucket("test-bucket");

let response = bucket.stat_object("test-key").call()?;
let object = response.into_body();
println!("fsize: {}", object.get_size_as_u64());
println!("hash: {}", object.get_hash_as_str());
println!("mime_type: {}", object.get_mime_type_as_str());

异步代码示例

use qiniu_objects_manager::{apis::credential::Credential, ObjectsManager};

let credential = Credential::new("abcdefghklmnopq", "1234567890");
let object_manager = ObjectsManager::builder(credential).build();
let bucket = object_manager.bucket("test-bucket");

let response = bucket.stat_object("test-key").async_call().await?;
let object = response.into_body();
println!("fsize: {}", object.get_size_as_u64());
println!("hash: {}", object.get_hash_as_str());
println!("mime_type: {}", object.get_mime_type_as_str());

对象批量元信息获取

阻塞代码示例

use qiniu_objects_manager::{apis::credential::Credential, ObjectsManager, OperationProvider};

let credential = Credential::new("abcdefghklmnopq", "1234567890");
let object_manager = ObjectsManager::builder(credential).build();
let bucket = object_manager.bucket("test-bucket");
let mut ops = bucket.batch_ops();
ops.add_operation(bucket.stat_object("test-file-1"));
ops.add_operation(bucket.stat_object("test-file-2"));
ops.add_operation(bucket.stat_object("test-file-3"));
ops.add_operation(bucket.stat_object("test-file-4"));
ops.add_operation(bucket.stat_object("test-file-5"));
let mut iter = ops.call();
while let Some(object) = iter.next() {
    let object = object?;
    println!("fsize: {:?}", object.get_size_as_u64());
    println!("hash: {:?}", object.get_hash_as_str());
    println!("mime_type: {:?}", object.get_mime_type_as_str());
}

异步代码示例

use qiniu_objects_manager::{apis::credential::Credential, ObjectsManager, OperationProvider};
use futures::stream::TryStreamExt;

let credential = Credential::new("abcdefghklmnopq", "1234567890");
let object_manager = ObjectsManager::builder(credential).build();
let bucket = object_manager.bucket("test-bucket");
let mut ops = bucket.batch_ops();
ops.add_operation(bucket.stat_object("test-file-1"));
ops.add_operation(bucket.stat_object("test-file-2"));
ops.add_operation(bucket.stat_object("test-file-3"));
ops.add_operation(bucket.stat_object("test-file-4"));
ops.add_operation(bucket.stat_object("test-file-5"));
let mut stream = ops.async_call();
while let Some(object) = stream.try_next().await? {
    println!("fsize: {:?}", object.get_size_as_u64());
    println!("hash: {:?}", object.get_hash_as_str());
    println!("mime_type: {:?}", object.get_mime_type_as_str());
}

对象列举

阻塞代码示例

use qiniu_objects_manager::{apis::credential::Credential, ObjectsManager};

let credential = Credential::new("abcdefghklmnopq", "1234567890");
let object_manager = ObjectsManager::builder(credential).build();
let bucket = object_manager.bucket("test-bucket");
let mut iter = bucket.list().iter();
while let Some(object) = iter.next() {
    let object = object?;
    println!("fsize: {:?}", object.get_size_as_u64());
    println!("hash: {:?}", object.get_hash_as_str());
    println!("mime_type: {:?}", object.get_mime_type_as_str());
}

异步代码示例

use qiniu_objects_manager::{apis::credential::Credential, ObjectsManager};
use futures::stream::TryStreamExt;

let credential = Credential::new("abcdefghklmnopq", "1234567890");
let object_manager = ObjectsManager::builder(credential).build();
let bucket = object_manager.bucket("test-bucket");
let mut stream = bucket.list().stream();
while let Some(object) = stream.try_next().await? {
    println!("fsize: {:?}", object.get_size_as_u64());
    println!("hash: {:?}", object.get_hash_as_str());
