我正在尝试使用javascript创建facebook连接,这会产生以下错误:
应用程序配置不允许使用URL:应用程序的设置不允许使用一个或多个给定的URL.它必须与网站URL或Canvas URL匹配,或者域必须是App域之一的子域.
是否是由于我使用Localhost服务器进行测试？我是否需要购买域名来测试这个或什么？或者我需要在以下代码中进行更改:
我的代码:
<?php
//
// uses the PHP SDK. Download from https://github.com/facebook/php-sdk
include("facebook-php-sdk/src/facebook.php");
//
// from the facebook app page
define('YOUR_APP_ID', '321849981247524');
define('YOUR_APP_SECRET', '49fd00ce6237aff0af08fd8ca25dbc92');
//
// new facebook object to interact with facebook
$facebook = new Facebook(array(
'appId' => YOUR_APP_ID,
'secret' => YOUR_APP_SECRET,
));
//
// if user is logged in on facebook and already gave permissions
// to your app, get his data:
$userId = $facebook->getUser();
?>
<html>
<head>
<style>body { text-align:center; font-size: 40px }</style>
</head> …我声明了一个char*数组 char *excluded_string[50] = { 0 };
之后,excluded_string数组的每个元素都会有一个单词.现在我想将它转换为字符串,以便我可以将所有单词分隔为空格.
std::string ss(excluded_string); 给出错误:
`server.cpp:171:32:错误:没有匹配函数来调用'std :: basic_string :: basic_string(char*[50])'和大的棘手的解释!
ispunct()以这种方式分离单词时效果很好"one, two; three".然后它将删除",;" 并用给定的字符替换.
但是如果以这种方式给出字符串,"ts='TOK_STORE_ID';"那么它将"ts='TOK_STORE_ID';"作为一个单一的标记,或者
"one,one, two;four$three two" 作为三个令牌 1. "one,one" 2. "two;four$three" 3. "two"
是否有任何一个"one,one, two;four$three two"可以被视为"one one two four three two"每个单独的令牌？
编写手动代码如:
for(i=0;i<str.length();i++)
{
//validating each character
}
当字符串非常长时,此操作将变得非常昂贵.
那么还有其他功能ispunct()吗？或其他什么？
在c中我们这样做来比较每个字符:
for(i=0;i<str.length();i++)
{
if(str[i]==',' || str[i]==",") // Is there any way here to compare with all puctuations in one shot?
str[i]=" "; //replace with space
}
在c ++中,这是正确的方法吗？
以下代码从char数组中正确删除了标点符号:
#include <cctype>
#include <iostream>
int main()
{
char line[] = "ts='TOK_STORE_ID'; one,one, two;four$three two";
for (char* c = line; *c; c++)
{
if (std::ispunct(*c))
{
*c = ' ';
}
}
std::cout << line << std::endl;
}
如果line类型是这样的代码将如何看std::string？
My main page is index.php. Here I perform user login and then redirected to url.php using ajax request. Now user may move to various pages.
I need current user facebook id on those pages. How can I get it?
login.php

window.fbAsyncInit = function() {
FB.init({
appId: '<?php
echo $appId;

我正在尝试使用 scikit 训练一些文本数据。在其他 PC 上使用相同的代码没有任何错误，但在我的系统上它给出了错误：

hidden_layer_sizes : tuple, length = n_layers - 2, default (100,)
我毫不怀疑.
在我的代码中,我配置的是
MLPClassifier(algorithm='l-bfgs', alpha=1e-5, hidden_layer_sizes=(5, 2), random_state=1)
什么做5和2表明？
我的理解是,5是隐藏层的数量,但那么2是什么？

我有php文件index.php
在这个文件中使用我正在做的html代码:
的index.php
echo '
<div>
<a class="fragment" href="">
<div>';
在href我想把一些PHP变量的值,即$url 如何做？
这是正确的方法吗？
<a class="fragment" href="<?php echo $url; ?>">
这是我从页面收集数据的功能.数据存储在数组中,最后我用var_dump()回显它.
数据被捆绑成长度为40的数组.我试图分别获得每个数组值.
当我使用转储时,数组结果如下所示var_dump($root):
object(stdClass)[1]
public 'items' =>
array (size=40)
0 =>
object(stdClass)[12983]
public 'comment' => string 'Locanda is great ! Maybe a bit overrated... But I definitely enjoyed my first dinner here! <br><br>Trippa alla romana is so good!

当我在Google上搜索时，我找到了此解决方案-https://github.com/fchollet/keras/tree/b587aeee1c1be1363363a56b945af3e7c2c303369ca
我尝试使用https://github.com/fchollet/keras/tree/b587aeee1c1be3633a56b945af3e7c2c303369ca上的代码Zip包
使用安装了keras，sudo python setup.py install但是当我运行提供的代码https://github.com/karimkhanp/Seq2Seq时，仍然遇到相同的错误。
如果有人找到任何解决方案，请提供帮助。
