Qiniu-Objects-Manager

概览

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。

安装

不启用异步接口，推荐使用 ureq

[dependencies]
qiniu-objects-manager = { version = "0.2.1", features = ["ureq"] }

启用 Isahc 异步接口

[dependencies]
qiniu-objects-manager = { version = "0.2.1", features = ["async", "isahc"] }

启用 Reqwest 异步接口

[dependencies]
qiniu-objects-manager = { version = "0.2.1", features = ["async", "reqwest"] }

其他功能

c_ares

启用 c-ares 库作为 DNS 解析器

trust_dns

启用 trust-dns 库作为 DNS 解析器

dns-over-https

启用 trust-dns 库作为 DNS 解析器，并使用 DOH 协议

dns-over-tls

启用 trust-dns 库作为 DNS 解析器，并使用 DOT 协议

代码示例

阻塞代码示例

对象元信息获取

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

let credential = Credential::new("abcdefghklmnopq", "1234567890");
let object_manager = ObjectsManager::new(credential);
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());

对象批量元信息获取

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

let credential = Credential::new("abcdefghklmnopq", "1234567890");
let object_manager = ObjectsManager::new(credential);
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());
}
