Rest Client for Vscode

Rest Client for Vsocde record all the request in plain text

• It can easily be managed by version control system via git
• Define the variables in the context to resue both
• Code hinting for the key prarameters

Installation

1. Open Visual Studio Code, press F1, type ext install then search for rest-client.
2. Create a new file called rest-test.http and cover the sample as below, replace the value with your own.

Disqus 对于静态站点着实好用，设计理念也能把言论处理的复杂度隔离开来 …
但是需要实现Disqus API的反向代理，于是乎开始了复习和整理 Nginx 反向代理的旅程

URL && URI

在做Location过滤前首先得了解什么是 URL 和 URI

A Uniform Resource Locator (URL), colloquially termed a web address,[1] is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier (URI),[2][3] although many people use the two terms interchangeably.[4][a] URLs occur most commonly to reference web pages (http), but are also used for file transfer (ftp), email (mailto), database access (JDBC), and many other applications.

Most web browsers display the URL of a web page above the page in an address bar. A typical URL could have the form http://www.example.com/index.html, which indicates a protocol (http), a hostname (www.example.com), and a file name (index.html).

A Uniform Resource Locator (URL) is a URI that specifies the means of acting upon or obtaining the representation of a resource, i.e. specifying both its primary access mechanism and network location. For example, the URL http://example.org/wiki/Main_Page refers to a resource identified as /wiki/Main_Page, whose representation, in the form of HTML and related code, is obtainable via the Hypertext Transfer Protocol (http:) from a network host whose domain name is example.org.

You can refer to the origin
https://en.wikipedia.org/wiki/URL
https://en.wikipedia.org/wiki/Uniform_Resource_Identifier

Nginx Location

Nginx 用 Location 的这个语法来匹配 URI
Locaiton 的匹配是自上而下以匹配项最多的那条规则为准，只有后面的正则表达式没有匹配到时，这一条才会采用当前rule

localtion / {
    # 所有请求都匹配以下规则
    # 因为所有的地址都以 / 开头，所以这条规则将匹配到所有请求
}

location = / {
    # 精确匹配 / ，后面带任何字符串的地址都不符合
}

localtion /api {
    # 匹配任何 /api 开头的URL，包括 /api 后面任意的, 比如 /api/getList
    # 匹配符合以后，还要继续往下搜索
    # 只有后面的正则表达式没有匹配到时，这一条才会采用这一条
}

localtion ~ /api/abc {
    # 匹配任何 /api/abc 开头的URL，包括 /api/abc 后面任意的, 比如 /api/abc/getList
    # 匹配符合以后，还要继续往下搜索
    # 只有后面的正则表达式没有匹配到时，这一条才会采用这一条
}

Nginx Cross-Origin Resource Sharing(代理跨域转发)

Scenario

本地启动了一个前后端分离的WEB应用，端口为：3000，可以通过 http://127.0.0.1:3000 访问前端页面，页面中有些Ajax请求的地址为 http://127.0.0.1:3000/api/getList ，一般情况下肯定是404或者请求失败

这种后端服务的接口存放在于其他的服务器中，比如在公司内网可以通过 http://172.30.1.123:8081/api/getList 访问到测试环境中的服务接口。这种情况的请求就涉及到端口不一样的跨域了，那么我们可以利用Nginx代理请求。

Nginx Configuration

Config it in {NGINX_ROOT}/nginx.conf

    location / {

    }

    location ~ /api/ {
        proxy_pass  http://172.30.1.123:8081;
    }
}

Nginx is lisening in port 80，将 http://127.0.0.1 的所有请求服务转发到 127.0.0.1 端口为 3000；
将 http://127.0.0.1/api/ 或者 http://127.0.0.1/api/getList 请求转发到 http://172.30.1.123:8081

Scenario for Disqus

Assign your domain name(https://disqus.leonvision.online) to your host
and dset the header to destination service.

The ADP National Employment Report provides a monthly snapshot of U.S. nonfarm private sector Employment based on actual transactional payroll data.

ADP National Enployment Reports 是在非农数据公布的前两天公布的，对非农数据有指引作用，人称“小非农” ，交易上倾向于根据小非农的数据来押注非农数据方向

Agency: 美国商务部

核心零售销售额是根据美国各种类型和规模的零售商店（不含汽车销售商店）抽样调查中所获得的零售商所售出的所有消费品销售额变动而作出的月度衡量。 它是消费开支的重要指标，并与消费者信心指数有关，被认为是美国经济的速度指标。
如果该指标比预期更高，则应认为美元强势/看涨，而如果该指标比预期更低，则应认为美元弱势/看跌。

ISM Non-Manufacturing PMI

ISM Non-Manufacturing PMI ：ISM非制造业PMI
Rating : 3 stars
Agency: Institute for supply management
Publish Date : 每个月第一周

供应管理研究所（ISM）非制造业指数（也称为ISM服务业）所跟踪的是上月发生的非制造业活动的数量。
任何超过50的指数表示扩大，小于50的表示缩小。
它对于GDP的影响比ISM制造业指数的要小得多。
如果该指标比预期更高，则应认为美元强势/看涨，而如果该指标比预期更低，则应认为美元弱势/看跌。

在美国，非制造业在经济中的比重高达75%以上，因此相关企业的就业趋势、新增订单及价格的变化对于观测美国经济整体变化也是不可或缺的。为了满足这一需求，ISM这一代表全国的公司采购经纪人的组织从1998年6月开始发布自己所编制的指数。尽管一开始，这项数据并没有引起太多人的足够重视，但随着时间的推移，经济学家以及政客们开始越来越关注这份公布及时且有助于预测重要经济指标（例如：通胀数据、就业数据）变化的经济指标。该指数有10个分指数，其中商业活动指数最为重要，其它9个分指数是新订单，供应商交货时间，就业，存货，物价，未完成订单，新出口订单，进口以及预期存货。

ISM每月将调查问卷发给17个行业的370多个采购经纪人，包括法律服务、娱乐、不动产、交通、保险、运输、银行以及宾馆。每个行业被调查公司所占的比例取决于该部门对GDP的贡献率。被调查者要求回答他们对以下所列出的对象的真实感受（高涨、冷清还是没变）

Annually Report

Federal Reserve System Monetary Policy Report

Federal Reserve System Monetary Policy Report : 美联储货币政策报告
Rating: 2 stars

Publish Date : 每半年一次

美联储(FED)货币政策报告是由美联储每六个月向国会提交的一份书面报告：包括负责银行业，住房和城市管理的参议院委员会，以及负责金融服务的众议院委员会。

该报告由三部分组成。第一部分包含对影响本国货币汇率的当前经济和金融发展的评估。它还提供了劳动力市场状况、GDP动态和GDP变化特征的描述，以及经济稳定性的评估和银行业发展的数据。

该报告的第二部分包括对国家货币政策的描述：采取的措施、对这些措施的解释以及实施措施的效率。在该报告中，监管机构描述了短期利率的变化和量化宽松的措施，以及国家外汇储备状况和金融体系的平衡。美国货币政策是由FOMC（联邦公开市场委员会）制定，旨在保持物价稳定、经济增长、充分就业和国际贸易的稳定性。

在第三部分中，美联储根据对当前事态发展的分析，对通货膨胀、失业率和经济增长情况提供了简要展望。

美联储报告是公开的。根据报告内容，经济学家试图预测美联储近期的利率变化并评估美国通货膨胀和经济前景。这份报告的发表对美元报价的影响轻微，因为其中包含的数据是事先知道的，美联储提供的解读也是可以预测的。

Front-matter is a block of YAML or JSON at the beginning of the file that is used to configure settings for your writings. Front-matter is terminated by three dashes when written in YAML or three semicolons when written in JSON.

Hexo Next already supported the mermaid nested.

Next use its own tag system to convert the diagram. so we need to fixed it aligning the common markdown practice.

This filter will convert the indicator '''mermaid to <pre class="mermaid">, and then mermaid.js will filter the elememet and redender them.
