Question

我尝试使用POST功能使用 httr 库访问R中的以下网址。我需要提取已开发脚本的一些货币汇率。我在验证工具内部有不同的时间段时遇到问题。

https://www.oanda.com/fx-for-business/historical-rates/auth/login/

我使用以下代码

  library(httr)

        Cookie = paste('opc_id=599C877C-7B4C-11E7-A634-FD6593E2D6B9;', 'csrftoken=EJqIgiufV77Nlv4E54mKoFcxhKGJgnO4cdQzUy2ehaayjD5FX21F8MznpHm0o4W5;','sessionid "6bc5s0qnswsue0pxe3st83ezf6m9cdl5;')

    headers = list (
    Host= "www.oanda.com",
        "User-Agent" = "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:54.0) Gecko/20100101 Firefox/54.0",
         Accept =  "*/*",
        "Accept-Language" = "en-US,en;q=0.5",
        "Accept-Encoding" =  "gzip, deflate, br",
        "Content-Type"= "application/x-www-form-urlencoded; charset=UTF-8",
        Referer =  "https://www.oand

a.com/fx-for-business/historical-rates",
    "Content-Length" = 64,
    "X-Requested-With" =  "XMLHttpRequest",
    Cookie = Cookie,    Connection= "keep-alive")

    .headers = character(headers)

    par = list (
    email = "user",
    password = "pass",
    redirect=""
    )

    POST("https://www.oanda.com/fx-for-business/historical-rates/auth/login/",body = pars, add_headers(.headers))

最后一行的结果如下。该脚本需要CSFR令牌，我该如何生成它？

        <h1>Forbidden 
            <span>(403)</span>
        </h1>
        <p>CSRF verification failed. Request aborted.</p>
        <p>You are seeing this message because this site requires a CSRF cookie when submitting forms. This cookie is required for security reasons, to ensure that your browser is not being hijacked by third parties.</p>
        <p>If you have configured your browser to disable cookies, please re-enable them, at least for this site, or for &#39;same-origin&#39; requests.</p>

GET＆amp;的结构。 POST是以下

GET https://www.oanda.com/static/sfb/hcc/templates/html/en/popup.login.html?_=1502097958941
    POST https://www.oanda.com/fx-for-business/historical-rates/auth/login/
    GET https://www.oanda.com/fx-for-business/historical-rates/getUser/?_=1502097958942
    GET https://www.oanda.com/fx-for-business/historical-rates/message/messages/?_=1502097958943
    GET https://www.oanda.com/static/sfb/hcc/templates/html/en/banner.expiry.html?_=1502097958944
    GET https://www.oanda.com/static/sfb/hcc/templates/html/en/popup.login.success.html?_=1502097958945

Answer 1

解决方案在于模拟R内部的Web浏览器。实现此目的的代码如下

$('.selLang').hover(function() {
    $("#myDialog").dialog('option', 'draggable', false);
},function(){
    $("#myDialog").dialog('option', 'draggable', true);
})

使用POST＆amp;登录RTR与CS中的CSFR令牌
