如何使用Boundary和PHP CURL执行POST请求

我正在尝试登录使用以下POST表单的网页：`

<div class="form"> </div>

    <fieldset class="inlined">
        <input type="hidden" name="label" value="">
        <input type="hidden" name="textName" value="j_username">
        <div class="field required ">
            <label for="_content_b2b_eu_login_jcr_content_par_start_j_username">Username</label>
            <input type="text" class=" large" id="_content_b2b_eu_login_jcr_content_par_start_j_username" name="j_username" value="" placeholder="" onkeydown="">

        </div>

        <input type="hidden" name="password" value="j_password">
        <div class="field required ">

            <label for="_content_b2b_eu_login_jcr_content_par_start_j_password">Password</label>
            <input class="large" id="_content_b2b_eu_login_jcr_content_par_start_j_password" type="password" autocomplete="off" name="j_password" value="" size="35">

        </div>

        <button type="button" class="pill cv-toggle">CV</button>
        <div class="button-bar">
            <button type="submit" class="button th-navigation ">LOG IN</button>
        </div>
        <div class="dynaLink parbase noLogin">

            <div class="field nolabel">
                <a href="/it/request-credentials">Hai dimenticato la password ?</a>
            </div>
        </div>
    </fieldset>
    <div class="end">

        <div class="form_row">
            <div class="form_leftcol"></div>
            <div class="form_rightcol"></div>
        </div>

    <div class="form_row_description"></div>
</div>

这样做，我写的代码是：

<div class="form"> </div>

    <fieldset class="inlined">
        <input type="hidden" name="label" value="">
        <input type="hidden" name="textName" value="j_username">
        <div class="field required ">
            <label for="_content_b2b_eu_login_jcr_content_par_start_j_username">Username</label>
            <input type="text" class=" large" id="_content_b2b_eu_login_jcr_content_par_start_j_username" name="j_username" value="" placeholder="" onkeydown="">

        </div>

        <input type="hidden" name="password" value="j_password">
        <div class="field required ">

            <label for="_content_b2b_eu_login_jcr_content_par_start_j_password">Password</label>
            <input class="large" id="_content_b2b_eu_login_jcr_content_par_start_j_password" type="password" autocomplete="off" name="j_password" value="" size="35">

        </div>

        <button type="button" class="pill cv-toggle">CV</button>
        <div class="button-bar">
            <button type="submit" class="button th-navigation ">LOG IN</button>
        </div>
        <div class="dynaLink parbase noLogin">

            <div class="field nolabel">
                <a href="/it/request-credentials">Hai dimenticato la password ?</a>
            </div>
        </div>
    </fieldset>
    <div class="end">

        <div class="form_row">
            <div class="form_leftcol"></div>
            <div class="form_rightcol"></div>
        </div>

    <div class="form_row_description"></div>
</div>

    $fields_array = array(

    'formid' => urlencode('_content_b2b_eu_login_jcr_content_par_start'),
    'formstart' => urlencode('/content/b2b/it/login/jcr:content/start'),
    '_charset_' => urlencode('UTF-8'),
    'redirect' => urlencode('/content/b2b/it/login/dashboard.html'),
    'label' => urlencode(''),
    'textName' => urlencode('j_username'),
    'j_username' => urlencode('MYUSERNAME'),
    'password' => urlencode('j_password'),
    'j_password' => urlencode('MYPASSWORD')

);

$fields_string = '';
foreach($fields_array as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');

$url = 'https://my.shimano-eu.com/it/login.html';
$boundary = '7aBMjcE3CIYntqQ3';

$header = array('Content-Type: multipart/form-data;----WebKitFormBoundary'.$boundary);

curl_setopt($ch,CURLOPT_HTTPHEADER,$header);
curl_setopt($ch, CURLOPT_COOKIEFILE, $ckfile); //Uses cookies from the temp file 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string); 
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
$output = curl_exec($ch);

之后，我看到它会自动发出POST请求“”，发布以下字段\u字符串：

<div class="form"> </div>

    <fieldset class="inlined">
        <input type="hidden" name="label" value="">
        <input type="hidden" name="textName" value="j_username">
        <div class="field required ">
            <label for="_content_b2b_eu_login_jcr_content_par_start_j_username">Username</label>
            <input type="text" class=" large" id="_content_b2b_eu_login_jcr_content_par_start_j_username" name="j_username" value="" placeholder="" onkeydown="">

        </div>

        <input type="hidden" name="password" value="j_password">
        <div class="field required ">

            <label for="_content_b2b_eu_login_jcr_content_par_start_j_password">Password</label>
            <input class="large" id="_content_b2b_eu_login_jcr_content_par_start_j_password" type="password" autocomplete="off" name="j_password" value="" size="35">

        </div>

        <button type="button" class="pill cv-toggle">CV</button>
        <div class="button-bar">
            <button type="submit" class="button th-navigation ">LOG IN</button>
        </div>
        <div class="dynaLink parbase noLogin">

            <div class="field nolabel">
                <a href="/it/request-credentials">Hai dimenticato la password ?</a>
            </div>
        </div>
    </fieldset>
    <div class="end">

        <div class="form_row">
            <div class="form_leftcol"></div>
            <div class="form_rightcol"></div>
        </div>

    <div class="form_row_description"></div>
</div>

j_username:MYUSERNAME
j_password:MYPASSWORD
j_validate:true
_charset_:UTF-8

我用下面的代码回答：

<div class="form"> </div>

    <fieldset class="inlined">
        <input type="hidden" name="label" value="">
        <input type="hidden" name="textName" value="j_username">
        <div class="field required ">
            <label for="_content_b2b_eu_login_jcr_content_par_start_j_username">Username</label>
            <input type="text" class=" large" id="_content_b2b_eu_login_jcr_content_par_start_j_username" name="j_username" value="" placeholder="" onkeydown="">

        </div>

        <input type="hidden" name="password" value="j_password">
        <div class="field required ">

            <label for="_content_b2b_eu_login_jcr_content_par_start_j_password">Password</label>
            <input class="large" id="_content_b2b_eu_login_jcr_content_par_start_j_password" type="password" autocomplete="off" name="j_password" value="" size="35">

        </div>

        <button type="button" class="pill cv-toggle">CV</button>
        <div class="button-bar">
            <button type="submit" class="button th-navigation ">LOG IN</button>
        </div>
        <div class="dynaLink parbase noLogin">

            <div class="field nolabel">
                <a href="/it/request-credentials">Hai dimenticato la password ?</a>
            </div>
        </div>
    </fieldset>
    <div class="end">

        <div class="form_row">
            <div class="form_leftcol"></div>
            <div class="form_rightcol"></div>
        </div>

    <div class="form_row_description"></div>
</div>

$url = 'https://my.shimano-eu.com/it/j_security_check';
$fields_string = 'j_username=MYUSERNAME&j_password=MYPASSWORD&j_validate=true&_charset_=UTF-8';

curl_setopt($ch, CURLOPT_COOKIEFILE, $ckfile); //Uses cookies from the temp file 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string); 
$output = curl_exec($ch);

显然，首先，代码向登录页面发出GET请求，将cookie存储在$ckfile中

<div class="form"> </div>

    <fieldset class="inlined">
        <input type="hidden" name="label" value="">
        <input type="hidden" name="textName" value="j_username">
        <div class="field required ">
            <label for="_content_b2b_eu_login_jcr_content_par_start_j_username">Username</label>
            <input type="text" class=" large" id="_content_b2b_eu_login_jcr_content_par_start_j_username" name="j_username" value="" placeholder="" onkeydown="">

        </div>

        <input type="hidden" name="password" value="j_password">
        <div class="field required ">

            <label for="_content_b2b_eu_login_jcr_content_par_start_j_password">Password</label>
            <input class="large" id="_content_b2b_eu_login_jcr_content_par_start_j_password" type="password" autocomplete="off" name="j_password" value="" size="35">

        </div>

        <button type="button" class="pill cv-toggle">CV</button>
        <div class="button-bar">
            <button type="submit" class="button th-navigation ">LOG IN</button>
        </div>
        <div class="dynaLink parbase noLogin">

            <div class="field nolabel">
                <a href="/it/request-credentials">Hai dimenticato la password ?</a>
            </div>
        </div>
    </fieldset>
    <div class="end">

        <div class="form_row">
            <div class="form_leftcol"></div>
            <div class="form_rightcol"></div>
        </div>

    <div class="form_row_description"></div>
</div>

在所有这些之后，两个请求中的响应总是“禁止”的

<div class="form"> </div>

    <fieldset class="inlined">
        <input type="hidden" name="label" value="">
        <input type="hidden" name="textName" value="j_username">
        <div class="field required ">
            <label for="_content_b2b_eu_login_jcr_content_par_start_j_username">Username</label>
            <input type="text" class=" large" id="_content_b2b_eu_login_jcr_content_par_start_j_username" name="j_username" value="" placeholder="" onkeydown="">

        </div>

        <input type="hidden" name="password" value="j_password">
        <div class="field required ">

            <label for="_content_b2b_eu_login_jcr_content_par_start_j_password">Password</label>
            <input class="large" id="_content_b2b_eu_login_jcr_content_par_start_j_password" type="password" autocomplete="off" name="j_password" value="" size="35">

        </div>

        <button type="button" class="pill cv-toggle">CV</button>
        <div class="button-bar">
            <button type="submit" class="button th-navigation ">LOG IN</button>
        </div>
        <div class="dynaLink parbase noLogin">

            <div class="field nolabel">
                <a href="/it/request-credentials">Hai dimenticato la password ?</a>
            </div>
        </div>
    </fieldset>
    <div class="end">

        <div class="form_row">
            <div class="form_leftcol"></div>
            <div class="form_rightcol"></div>
        </div>

    <div class="form_row_description"></div>
</div>

我在这里三天了，我错在哪里了

<div class="form"> </div>

    <fieldset class="inlined">
        <input type="hidden" name="label" value="">
        <input type="hidden" name="textName" value="j_username">

            <label for="_content_b2b_eu_login_jcr_content_par_start_j_username">Username</label>
            <input type="text" class=" large" id="_content_b2b_eu_login_jcr_content_par_start_j_username" name="j_username" value="" placeholder="" onkeydown="">

        </div>

        <div class="button-bar">
            <button type="submit" class="button th-navigation ">LOG IN</button>
        </div>
        <div class="dynaLink parbase noLogin">

            <div class="field nolabel">
                <a href="/it/request-credentials">Hai dimenticato la password ?</a>
            </div>
        </div>
    </fieldset>
    <div class="end">

        <div class="form_row">
            <div class="form_leftcol"></div>
            <div class="form_rightcol"></div>
        </div>

    <div class="form_row_description"></div>
</div>

这是我尝试登录的页面：。

侧注：您不必将查询字符串传递给

CURLOPT_POSTFIELDS

，也可以传递包含字段的数组。正如@CharlotteDunois所指出的，您可以将参数数组传递给curl请求-这有效地更改了

enctype

（内容类型）从

application/x-www-form-urlencoded

到“multipart/formdata”-这就是边界发挥作用的地方感谢你们的回答，我在中更改了Curl请求：Curl_setopt（$ch，CURLOPT_HTTPHEADER，$header）；curl_setopt（$ch，CURLOPT_COOKIEFILE，$ckfile）；curl_setopt（$ch，CURLOPT_RETURNTRANSFER，1）；curl_setopt（$ch，CURLOPT_URL，$URL）；curl_setopt（$ch，CURLOPT_POST，count（$fields_array））；curl_setopt（$ch，CURLOPT_POSTFIELDS，$fields_数组）；curl_setopt（$ch，CURLINFO_HEADER_OUT，true）$输出=curl_exec（$ch）；但不幸的是，响应il也是“禁止的”。旁注：您不必将查询字符串传递给
