在应用程序中模拟网站

Question

我尝试通过以下操作在9GAG上模拟报告按钮：

string url = "http://9gag.com/gag/aKBQ00O";
string parameters = "radio-report=1";
using( WebClient wc = new WebClient( ) ) {
    wc.Headers[ HttpRequestHeader.ContentType ] = "application/x-www-form-urlencoded";
    string HtmlResult = wc.UploadString( url, parameters );
    Console.WriteLine( HtmlResult );
}

并且发生WebException并显示一条消息，提示服务器发送了404 NOT FOUND错误。 对于那些不想去9GAG看到我正在模拟的表格的人，这里：

<section id="modal-report" class="badge-overlay-report modal report">
    <header>
        <h3>Report Post</h3>
        <p>What do you report this post for?</p>
        <a class="btn-close badge-overlay-close" href="#">✖</a>
    </header>
    <form id="form-modal-report" class="popup-report" action="" onsubmit="return true;">
        <div class="field checkbox">
            <label><input name="radio-report" type="radio" value="1"> Contains a trademark or copyright violation</label>
        </div>
        <div class="field checkbox">
            <label><input name="radio-report" type="radio" value="2"> Spam, blatant advertising, or solicitation</label>
        </div>
        <div class="field checkbox">
            <label><input name="radio-report" type="radio" value="3"> Contains offensive materials/nudity</label>
        </div>
        <div class="field checkbox">
            <label><input name="radio-report" type="radio" value="4"> Repost of another post on 9GAG</label>

            <input id="jsid-repost-link" type="text" class="text" placeholder="http://9gag.com/gag/post_ID">
        </div>

        <div class="btn-container">
            <input type="submit" value="Submit" data-text-loading="Please wait ...">
        </div>
    </form>
</section>

它当然取自http://9gag.com/gag/aKBQ00O 。

我想念什么吗？ 还是我处于完全不同的方向？

Answer 1

通过开发者工具检查网络标签

我可以看到它实际上发布到

http://9gag.com/report-post

数据如下：（第四个单选按钮的类型= 4）

entryId=aKBQ00O&type=4&link=

因此，您应该像这样更改代码：（但是应该动态定义类型和链接参数）

string url = "http://9gag.com/report-post";
string parameters = "entryId=aKBQ00O&type=4&link=";
using (WebClient wc = new WebClient())
{
    wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
    string HtmlResult = wc.UploadString(url,  parameters);
    Console.WriteLine(HtmlResult);
}
