2019独角兽企业重金招聘Python工程师标准>>> 
IPFS支持Python接口访问，这里是其API参考手册。
- 相关连接：
- IPFS 服务的Python访问
- 通过Helm在Kubernetes集群上安装IPFS
- IPFS在Kubernetes部署的服务开放
- Run IPFS in a Docker container
- IPFS—快速运行容器服务
- IPFS 命令大全
所有的Python方法接受下列的参数：
- opts (dict) – 自定义参数的 dictonary 结构，被发送到HTTP request中。
连接
ipfsapi.connect(host='localhost', port=5001, base='api/v0', chunk_size=4096, **defaults)[source]
Create a new Client instance and connect to the daemon to validate that its version is supported.
| Raises: |
|
|---|
All parameters are identical to those passed to the constructor of the Client class.
| Returns: | ~ipfsapi.Client |
|---|
版本检查
ipfsapi.assert_version(version, minimum='0.4.3', maximum='0.5.0')[source]
Make sure that the given daemon version is supported by this client version.
| Raises: |
|
|---|---|
| Parameters: |
|
Client类
- class
ipfsapi.Client(host='localhost', port=5001, base='api/v0', chunk_size=4096, **defaults)[source]
Bases: object
A TCP client for interacting with an IPFS daemon.
A Client instance will not actually establish a connection to the daemon until at least one of it's methods is called.
| Parameters: |
|
|---|
添加文件
add(files, recursive=False, pattern='**', *args, **kwargs)[source]
Add a file, or directory of files to IPFS.
>>> with io.open('nurseryrhyme.txt', 'w', encoding='utf-8') as f:
... numbytes = f.write('Mary had a little lamb')
>>> c.add('nurseryrhyme.txt')
{'Hash': 'QmZfF6C9j4VtoCsTp4KSrhYH47QMd3DNXVZBKaxJdhaPab',
'Name': 'nurseryrhyme.txt'}
| Parameters: |
|
|---|---|
| Returns: | dict (File name and hash of the added file node) |
下载文件
get(multihash, **kwargs)[source]
Downloads a file, or directory of files from IPFS.
Files are placed in the current working directory.
| Parameters: | multihash (str) -- The path to the IPFS object(s) to be outputted |
|---|
查看内容
cat(multihash, **kwargs)[source]
Retrieves the contents of a file identified by hash.
>>> c.cat('QmTkzDwWqPbnAh5YiV5VwcTLnGdwSNsNTn2aDxdXBFca7D')
Traceback (most recent call last):
...

<h2>域名解析</h2>
<ul>
<li><code>dns</code>(<em>domain_name</em>, <em>recursive=False</em>, <em>**kwargs</em>)[source]</li>
</ul>
<p>Resolves DNS links to the referenced object.</p>
<p>Multihashes are hard to remember, but domain names are usually easy to remember. To create memorable aliases for multihashes, DNS TXT records can point to other DNS links, IPFS objects, IPNS keys, etc. This command resolves those links to the referenced object.</p>
<p>For example, with this DNS TXT record:</p>
<pre>>>> import dns.resolver
>>> a = dns.resolver.query("ipfs.io", "TXT")
>>> a.response.answer[0].items[0].to_text()
'"dnslink=/ipfs/QmTzQ1JRkWErjk39mryYw2WVaphAZNAREyMchXzYQ7c15n"'</pre>
<p>The resolver will give:</p>
<pre>>>> c.dns("ipfs.io")
{'Path': '/ipfs/QmTzQ1JRkWErjk39mryYw2WVaphAZNAREyMchXzYQ7c15n'}</pre>

<h2>查找DHT获得给定key的最佳值</h2>
<ul>
<li><code>dht_get</code>(<em>key</em>, <em>*keys</em>, <em>**kwargs</em>)[source]</li>
</ul>
<p>Queries the DHT for its best value related to given key.</p>
<p>There may be several different values for a given key stored in the DHT; in this context <em>best</em> means the record that is most desirable. There is no one metric for <em>best</em>: it depends entirely on the key type. For IPNS, <em>best</em> is the record that is both valid and has the highest sequence number (freshest). Different key types may specify other rules for they consider to be the <em>best</em>.</p>

<h2>向DHT中写入键值对</h2>
<ul>

<p>Writes a key/value pair to the DHT.</p>
<p>Given a key of the form <code>/foo/bar</code> and a value of any form, this will write that value to the DHT with that key.</p>
<p>Keys have two parts: a keytype (foo) and the key name (bar). IPNS uses the <code>/ipns/</code> keytype, and expects the key name to be a Peer ID. IPNS entries are formatted with a special strucutre.</p>
<p>You may only use keytypes that are supported in your <code>ipfs</code> binary: <code>go-ipfs</code> currently only supports the <code>/ipns/</code> keytype. Unless you have a relatively deep understanding of the key's internal structure, you likely want to be using the <code>name_publish()</code> instead.</p>
<p>Value is arbitrary text.</p>

<div>计数排序：是一种基于哈希的排序算法。他的基本思想是通过统计每个元素的出现次数，然后根据统计结果将元素依次放入排序后的序列中。这种排序算法适用于范围较小的情况，例如整数范围在0到k之间计数排序步骤：1初始化一个长度为最大元素值加1的计数数组，所有元素初始化为02遍历原始数组，将每个元素值作为索引，在计数数组中对应位置加13将数组清空4遍历计数器数组，按照数组中的元素个数放回到元数组中计数排序的优点和</div>

<div>要解决这个问题的时候，到网上查了很多方案，最后计算出来的都与百度计算出来的有出入。下面这个公式计算出来的距离和百度计算出来的距离是一致的。

<div>1、Java8已经到来。什么！？ Java8 支持lambda。哇哦，RIP Scala！ 随着Java8 的发布，出现很多关于新发布的Java8是否有潜力干掉Scala的争论，最终的结论是远远没有那么简单。Java8可能已经在Scala的lambda的包围中突围，但Java并非是函数式编程王位的真正觊觎者。
2、Java 9 即将到来
Oracle早在8月份就发布</div>

<div> 题目链接：zoj 3826 Hierarchical Notation
题目大意：给定一些结构体，结构体有value值和key值，Q次询问，输出每个key值对应的value值。
解题思路：思路很简单，写个类词法的递归函数，每次将key值映射成一个hash值，用map映射每个key的value起始终止位置，预处理完了查询就很简单了。 这题是最后10分钟出的，因为没有考虑value为{}的情</div>
