我知道在Stackoverflow上有与此类似的帖子，但是我仍然无法弄清楚我的尝试出了什么问题.

I know there are very similar posts to this on Stackoverflow but I still can't seem to figure out what is wrong with my attempt.

# login to the site mech.get(base_URL) do |page| l = page.form_with(:action => "/site/login/") do |f| username_field = f.field_with(:name => "LoginForm[username]") username_field.value = userName password_field = f.field_with(:name => "LoginForm[password]") password_field.value = password f.submit end end

这是我的错误:

rb:18:in `block (2 levels) in <main>': undefined method `field_with' for nil:NilClass (NoMethodError)

这是HTML

<div class="bucketbody"> <div class="form padding10"> <form id="login-form" action="/site/login" method="post"> <div class="row"> <p class="note float_right">Fields with <span class="required">*</span> are required.</p> <label for="LoginForm_username" class="required">Email address <span class="required">*</span></label> <input class="width_66per" autofocus="" name="LoginForm[username]" id="LoginForm_username" type="text"> </div> <div class="row"> <label for="LoginForm_password" class="required">Password <span class="required">*</span></label> <input class="width_66per" name="LoginForm[password]" id="LoginForm_password" type="password"> </div> <div class="row rememberMe nolabel"> <span class="field"><input id="ytLoginForm_rememberMe" value="0" name="LoginForm[rememberMe]" type="hidden"><input name="LoginForm[rememberMe]" id="LoginForm_rememberMe" value="1" type="checkbox"> <label for="LoginForm_rememberMe">Remember me on this computer</label> </span> </div> <p class="note"><a href="test.XXXXXXXX/user/reset">Forgot your password?</a></p> <div class="row buttons" style="padding-left: 0px;"> <input class="pushButton" name="yt0" value="Login" type="submit"> </div> </form> </div><!-- form --> </div>

推荐答案

您正在使它变得比所需的更为复杂:

You're making it more complicated than it needs to be:

page = mech.get base_URL form = page.form # page.forms[1], etc. form['LoginForm[username]'] = userName form['LoginForm[password]'] = password l = form.submit form.button
