<div class="post-text" itemprop="text"> <p>I'm attempting to load some HTML stored as text for a knockout.js form. A customer's server will use an AJAX GET call to my server which will then return the HTML for the table. Right now, the table is being returned, however it's formatted like knockout.js hasn't been loaded but I'm not receiving any errors (dropdown not populated, foreach loop for a table is displaying a blank row, a secondary div is displayed when it should only be displayed once a submit button has been pressed). </p> <p>When I have the HTML on this page it works, so I'm pretty sure it's not incorrect code in the form. The only thing I can think of is that knockout is picky about single and double quotes, although I feel like that would rsult in errors. Right now I'm testing on my server so same origin policy shouldn't be an issue at the moment. </p> <p>Here is the page that initially loads</p> <pre><code>//main.html &lt;script src="//" &gt;&lt;/script&gt; &lt;!-- I also tried to include the knockout file includes here but made no difference --&gt; &lt;script&gt; &lt;!-- call to get HTML for knockout form --&gt; $.ajax({ type: 'GET', url: '/orders/return_form', data: "true", success: function(response) { // on success.. $('#order_div').html(response); // update the DIV } }) &lt;/script&gt; &lt;div id = "order_div"&gt; &lt;!-- returned knockout form goes here --&gt; &lt;/div&gt; &lt;script src="knockout.js"&gt;&lt;/script&gt; &lt;script src="knockout_info.js"&gt;&lt;/script&gt; &lt;!-- MVVM file --&gt; &lt;script src = "Knockout-Validation/Src/knockout.validation"&lt;/script&gt; </code></pre> <p>Here is the code to return the code for the table</p> <pre><code>//orders/return_form if($_GET['true']){ echo "table code here "; //I tried to encode this before but got all kinds of extra markup due to whitespace and other misc. characters //or $form = new stdClass; $form-&gt;table = "&lt;form method='post'&gt; &lt;input type='textbox' name='text'/&gt; &lt;input type='submit' name='textsubmit'/&gt; &lt;/form&gt;"; echo $form-&gt;table; } </code></pre> <p>If I include the table instead of calling for the code it works.

<div class="post-text" itemprop="text"> <p>I'm incorporating paypal into my site , however, once I receive the token and try to redirect to paypal's site, nothing happens. I'm using knockout.js on my front end. When I click a button to make a GET request, the values are sent over to a corresponding CakePHP action which verifies the data and then redirect to paypal's site to finish the transaction. </p> <p>Now here's the strange part. At first I assumed I messed up the jQuery to make the GET but that doesn't seem to be the case. When I make the GET request with the header('location...') code included in the corresponding action, the network tab shows the request failed as "canceled". However, when I comment out the header('location..') code the request goes through successfully.</p> <p>Here's GET request on</p> <pre><code>//order_processing.js $.getJSON("/orders/pay_for_order/" + itemNumbers + "/" + quantities + "/" + prices + "/" + productNames + "/" + self.fullName() + "/" + self.addressLine1() + " " + self.addressLine2() + "/" + + "/" + self.state() + "/" + self.ZIP() + "/" +,function(data) { }); </code></pre> <p>Here's the action that the request goes to</p> <pre><code>//OrdersController function pay_for_order($id = null){ //processing code here //get token from paypal if($finalize_order-&gt;verifyPrice($item_numbers, $prices) == TRUE){ //when I comment out this header redirect the GET request is successful, but of course then does not redirect header( 'Location:;token='.$token ) ; } } </code></pre> <p>I know my calls to paypal are working correctly to get the token, because when I copy/paste the link into the address bar it then redirects (meaning the token was successfully received). This to me seems like it's an issue with jQuery making the request. However, I'm confused as to why the GET request fails when I have the header redirect included, but when it's commented out the GET passes. </p> <p><strong>Update</strong></p> <p>I swapped out the header redirect for the following and it doesn't fail, however, it doesn't redirect either. This code showing up in the response as well, so I think this probably means CakePHP does not like header('location') redirects. </p> <pre><code>echo '&lt;META HTTP-EQUIV="Refresh" Content="0; URL=;token='.$token.'"&gt;'; </code></pre> </div>

【为什么学爬虫?】 &nbsp; &nbsp; &nbsp; &nbsp;1、爬虫入手容易,但是深入较难,如何写出高效率的爬虫,如何写出灵活性高可扩展的爬虫都是一项技术活。另外在爬虫过程中,经常容易遇到被反爬虫,比如字体反爬、IP识别、验证码等,如何层层攻克难点拿到想要的数据,这门课程,你都能学到! &nbsp; &nbsp; &nbsp; &nbsp;2、如果是作为一个其他行业的开发者,比如app开发,web开发,学习爬虫能让你加强对技术的认知,能够开发出更加安全的软件和网站 【课程设计】 一个完整的爬虫程序,无论大小,总体来说可以分成三个步骤,分别是: 网络请求:模拟浏览器的行为从网上抓取数据。 数据解析:将请求下来的数据进行过滤,提取我们想要的数据。 数据存储:将提取到的数据存储到硬盘或者内存中。比如用mysql数据库或者redis等。 那么本课程也是按照这几个步骤循序渐进的进行讲解,带领学生完整的掌握每个步骤的技术。另外,因为爬虫的多样性,在爬取的过程中可能会发生被反爬、效率低下等。因此我们又增加了两个章节用来提高爬虫程序的灵活性,分别是: 爬虫进阶:包括IP代理,多线程爬虫,图形验证码识别、JS加密解密、动态网页爬虫、字体反爬识别等。 Scrapy和分布式爬虫:Scrapy框架、Scrapy-redis组件、分布式爬虫等。 通过爬虫进阶的知识点我们能应付大量的反爬网站,而Scrapy框架作为一个专业的爬虫框架,使用他可以快速提高我们编写爬虫程序的效率和速度。另外如果一台机器不能满足你的需求,我们可以用分布式爬虫让多台机器帮助你快速爬取数据。 &nbsp; 从基础爬虫到商业化应用爬虫,本套课程满足您的所有需求! 【课程服务】 专属付费社群+每周三讨论会+1v1答疑
