【PowerShell专栏】命令中的Confirm参数

Confirm 参数是用来确认命令执行操作的再确认，默认情况下命令执行过程是否需要再确认取决于 PowerShell 中的ConfirmPreference的值。如果希望在PowerShell执行过程中改变再确认选项，可以通过Confirm参数替换ConfirmPreference首选项的值。在实际的命令中，如果希望了解目前PowerShell命令是否支持Confirm参数，我们可以通过Get-help -Parameter获取Confirm 的参数设定，图为New-Item的Confirm参数。

Model Context Protocol (MCP) 是一个开放协议，旨在标准化应用程序如何为大型语言模型（LLMs）提供上下文。MCP 类似于 AI 应用的 USB-C 接口，提供了一种标准化的方式，将 AI 模型连接到不同的数据源和工具。MCP 的核心架构采用客户端-服务器模式，主机应用程序可以连接到多个服务器，访问本地和远程数据源。MCP 提供了预构建的集成、灵活的 LLM 供应商切换以及数据安全的最佳实践。开发者可以根据需求选择快速入门指南，构建自己的服务器或客户端，或使用预构建的服务器。MCP

通过单词含义，就可以理解WarningAction参数和执行命令过程中的警告有关系，该参数就是在PowerShell命令执行过程中出现警告之后进行的操作，默认环境中存在WarningPreference参数定义命令执行过程中出现警告的操作，当然也可以出现警告的时候执行特殊的操作，这个时候可以使用WarningAction参数进行设置，从而覆盖默认的警告参数。它的使用方式和ErrorVariable参数比较类似。说明：警告信息对于命令的排错调试还是非常有意义的，如果不是自动化的脚本建议保留。

前言 似乎好像大概有句话是这么说得，好程序与坏程序之间的区别就在于它的鲁棒性,也就是在异常情况下该程序是否还是在可hold住状态，能否不死，不崩溃，或者不做出一些超出预期的事情。那要做好这些，自然而然就要学会如何去处理异常。平时写php或者java程序等等的时候，很多人都会去注重对于异常的处理，比如try..catch等等，但往往在写一些脚本的时候，忽视了对于异常的判断。本文主要就是写如何在

Authentication Endpoint security type API requests are likely to be tampered during transmission through the internet. To ensure that the request remains unchanged, all private interfaces other than public interfaces (basic information, market data) must be verified by signature authentication via API-KEY to make sure the parameters or configurations are unchanged during transmission. Each created API-KEY need to be assigned with appropriate permissions in order to access the corresponding interface. Before using the interface, users is required to check the permission type for each interface and confirm there is appropriate permissions. Authentication Type Description NONE Endpoints are freely accessible TRADE Endpoints requires sending a valid API-KEY and signature USER_DATA Endpoints requires sending a valid API-KEY and signature USER_STREAM The endpoints requires sending a valid API-KEY MARKET_DATA The endpoints requires sending a valid API-KEY Signature Authentication Signature (TRADE & USER_DATA) The SIGNED (signature required) endpoint needs to send a parameter, signature, in the query string or request body. The endpoint is signed with HMAC SHA256. The HMAC SHA256 signature is the result of HMAC SHA256 encryption of the key. Use your secretKey as the key and totalParams as the value to complete this encryption process. Signature is not case sensitive. totalParams refers to concatenation of the query string and the request body. All HTTP requests to API endpoints require authentication and authorization. The following headers should be added to all HTTP requests: Key Value Type Description X-HK-APIKEY API-KEY string The API Access Key you applied for Time-base security requirement For a SIGNED endpoint, an additional parameter "timestamp" needs to be included in the request. This timestamp is in milliseconds and reflect the time when the request was initiated. An optional parameter (not mandatory) recvWindow can be used to specify the validity period of the request in milliseconds. If recvWindow is not sent as part of the request, the default value is 5000 📘 If your timestamp is ahead of serverTime it needs to be within 1 second + serverTime The logic of this parameter is as follows: Java if (timestamp < (serverTime + 1000) && (serverTime - timestamp) <= recvWindow) { // process request } else { // reject request } Trading and timeliness are closely interconnected. Network can sometimes be unstable or unreliable, which can lead to inconsistent times when requests are sent to the server. With recvWindow, you can specify how many milliseconds the request is valid, otherwise it will be rejected by the server. 📘 A relatively small recvWindow (5000 or less) is recommended! Example 1: In queryString queryString: symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000 HMAC SHA256 signature: echo -n "symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000" | openssl dgst -sha256 -hmac "lH3ELTNiFxCQTmi9pPcWWikhsjO04Yoqw3euoHUuOLC3GYBW64ZqzQsiOEHXQS76" Shell standard output: 5f2750ad7589d1d40757a55342e621a44037dad23b5128cc70e18ec1d1c3f4c6 curl command: Shell curl -H "X-HK-APIKEY: tAQfOrPIZAhym0qHISRt8EFvxPemdBm5j5WMlkm3Ke9aFp0EGWC2CGM8GHV4kCYW" -X POST 'https://$HOST/api/v1/spot/order?symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000&signature=5f2750ad7589d1d40757a55342e621a44037dad23b5128cc70e18ec1d1c3f4c6' Example 2: In the request body requestBody: symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000 HMAC SHA256 signature: Shell echo -n "symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000" | openssl dgst -sha256 -hmac "lH3ELTNiFxCQTmi9pPcWWikhsjO04Yoqw3euoHUuOLC3GYBW64ZqzQsiOEHXQS76" Shell standard output: 5f2750ad7589d1d40757a55342e621a44037dad23b5128cc70e18ec1d1c3f4c6 curl command: Shell curl -H "X-HK-APIKEY: tAQfOrPIZAhym0qHISRt8EFvxPemdBm5j5WMlkm3Ke9aFp0EGWC2CGM8GHV4kCYW" -X POST 'https://$HOST/api/v1/spot/order' -d 'symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000&signature=5f2750ad7589d1d40757a55342e621a44037dad23b5128cc70e18ec1d1c3f4c6' Example 3: mixing queryString and request body queryString: symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC requestBody: quantity=1&price=0.1&recvWindow=5000×tamp=1538323200000 HMAC SHA256 signature: Shell echo -n "symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTCquantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000" | openssl dgst -sha256 -hmac "lH3ELTNiFxCQTmi9pPcWWikhsjO04Yoqw3euoHUuOLC3GYBW64ZqzQsiOEHXQS76" Shell standard output: 885c9e3dd89ccd13408b25e6d54c2330703759d7494bea6dd5a3d1fd16ba3afa curl command: Shell curl -H "X-HK-APIKEY: tAQfOrPIZAhym0qHISRt8EFvxPemdBm5j5WMlkm3Ke9aFp0EGWC2CGM8GHV4kCYW" -X POST 'https://$HOST/openapi/v1/order?symbol=ETHBTC&side=BUY&type=LIMIT&timeInForce=GTC' -d 'quantity=1&price=0.1&recvWindow=5000&timestamp=1538323200000&signature=885c9e3dd89ccd13408b25e6d54c2330703759d7494bea6dd5a3d1fd16ba3afa' Note the difference in Example 3, where there is no & between "GTC" and "quantity = 1". 根据以上描述生成Python的authentication
