  • 在PowerShell中使用curl(Invoke-WebRequest)

    前言

    习惯了windows的界面模式就很难转去命令行,甚至以命令行发家的git也涌现出各种界面tool。然而命令行真的会比界面快的多,如果你是一个码农。

    situation:接到需求分析bug,需要访问http。那台机器属于product,不允许装postman。我只能手动命令行来发请求。发现了内置的PowerShell中有curl命令。欢喜试了半天,总是命令不对,google发现这个curl是冒名顶替的,只是一个Invoke-WebRequest的alias。参考

    PS> Get-Alias -Definition Invoke-WebRequest | Format-Table -AutoSize CommandType Name Version Source ----------- ---- ------- ------ Alias curl -> Invoke-WebRequest Alias iwr -> Invoke-WebRequest Alias wget -> Invoke-WebRequest




    Invoke-WebRequest简单用法

    1.用途

    Gets content from a web page on the Internet.

    获取http web请求访问内容

    2.语法Syntax

    Parameter Set: Default Invoke-WebRequest [-Uri] <Uri> [-Body <Object> ] [-Certificate <X509Certificate> ] [-CertificateThumbprint <String> ] [-ContentType <String> ] [-Credential <PSCredential> ] [-DisableKeepAlive] [-Headers <IDictionary> ] [-InFile <String> ] [-MaximumRedirection <Int32> ] [-Method <WebRequestMethod> {Default | Get | Head | Post | Put | Delete | Trace | Options | Merge | Patch} ] [-OutFile <String> ] [-PassThru] [-Proxy <Uri> ] [-ProxyCredential <PSCredential> ] [-ProxyUseDefaultCredentials] [-SessionVariable <String> ] [-TimeoutSec <Int32> ] [-TransferEncoding <String> {chunked | compress | deflate | gzip | identity} ] [-UseBasicParsing] [-UseDefaultCredentials] [-UserAgent <String> ] [-WebSession <WebRequestSession> ] [ <CommonParameters>]

    3.简单的几个用法

    3.1 Get请求

    PS C:Users miao> curl -URi https://www.google.com StatusCode : 200 StatusDescription : OK Content : <!doctype html><html itemscope="" itemtype="http://schema.org/WebPage" lang="en"><head><meta content="Search the world's information, including webpages, images, videos and more. Google has many speci..." RawContent : HTTP/1.1 200 OK X-XSS-Protection: 1; mode=block X-Frame-Options: SAMEORIGIN Alt-Svc: quic=":443"; ma=2592000; v="36,35,34,33,32" Vary: Accept-Encoding Transfer-Encoding: chunked

    会发现content内容被截断了。想要获取完整的content:

    ps> curl https://www.google.com | Select -ExpandProperty Content

    3.2添加header

    -Headers @{"accept"="application/json"}

    3.3指定Method

    -Method Get

    3.4将获取到的content输出到文件

    -OutFile 'c:Users miao empcontent.txt'

    3.5表单提交

    For example:

    $R = Invoke-WebRequest http://website.com/login.aspx $R.Forms[0].Name = "MyName" $R.Forms[0].Password = "MyPassword" Invoke-RestMethod http://website.com/service.aspx -Body $R

    or

    Invoke-RestMethod http://website.com/service.aspx -Body $R.Forms[0]

    3.6内容筛选

    PS C:Users miao> $R = Invoke-WebRequest -URI http://www.bing.com?q=how+many+feet+in+a+mile PS C:Users miao> $R.AllElements | where {$_.innerhtml -like "*=*"} | Sort { $_.InnerHtml.Length } | Select InnerText - First 5 innerText --------- = 1 Next =

    3.7一个登陆示例

    #发送一个登陆请求,声明一个sessionVariable 参数为fb, 将结果保存在$R #这个变量FB就是header.cookie等集合 PS C:Users miao> $R=curl http://www.facebook.com/login.php -SessionVariable fb PS C:Users miao> $FB Headers : {} Cookies : System.Net.CookieContainer UseDefaultCredentials : False Credentials : Certificates : UserAgent : Mozilla/5.0 (Windows NT; Windows NT 6.3; en-US) WindowsPowerShell/4.0 Proxy : MaximumRedirection : -1 #将response响应结果中的第一个form属性赋值给变量Form PS C:Users miao> $Form=$R.Forms[0] PS C:Users miao> $Form.fields Key Value --- ----- lsd AVqQqrLW display enable_profile_selector isprivate legacy_return 0 profile_selector_ids return_session skip_api_login signed_next trynum 1 u_0_0 u_0_1 lgnrnd 214945_qGeg lgnjs n email pass persistent default_persistent 1 # 查看form PS C:Users miao> $Form | Format-List Id : login_form Method : post Action : /login.php?login_attempt=1&lwv=100 Fields : {[lsd, AVqQqrLW], [display, ], [enable_profile_selector, ], [isprivate, ]...} #查看属性 $Form.fields #设置账号密码 $Form.Fields["email"] = "User01@Fabrikam.com" $Form.Fields["pass"] = "P@ssw0rd" #发送请求并保存结果为$R $R=Invoke-WebRequest -Uri ("https://www.facebook.com" + $Form.Action) -WebSession $FB -Method POST -Body $Form.Fields #查看结果 PS C:Users miao> $R.StatusDescription OK

    虽然没有curl那么主流,但一样可以成为http访问的一个选择。
