Use PHP to simulate logging into WAP Fetion to send Fetion_PHP tutorial

There are currently many third-party Fetion interfaces on the Internet. The disadvantage is that they are not very stable, and many of them are now invalid and cannot be used. In addition, we are also worried about the leakage of information. In fact, we can implement such an interface ourselves. The idea I give here is very simple: by simulating login to the WAP version of Fetion, we can send Fetion and other operations. I chose WAP Fetion mainly because its interface is relatively simple, easy to analyze, and there is no verification code.

1. Install Firefox plug-in Use PHP to simulate logging into WAP Fetion to send Fetion_PHP tutorial

In this way, we can directly use Firefox to browse WAP web pages, and we can also use Firebug to analyze the interface. Download address: https://addons.mozilla.org/zh-CN/firefox/search/?q=Use PHP to simulate logging into WAP Fetion to send Fetion_PHP tutorial&cat=all&x=17&y=11

2. Analysis of login page

The WAP Fetion entrance is http://f.10086.cn/, click "Chat WAP Fetion" to enter the login page (http://f.10086.cn/im/login/login.action). It can be seen through Firebug:

There are 3 fields: pass (password), loginstatus (login status), m (mobile phone number)
Submitted action: http://f.10086.cn/im/login/inputpasssubmit1.action

In fact, there is a trick to get the fields submitted by the form: modify the action so that it points to your own program, as shown below:

I changed the action to a local php program. This program is just a simple print_r($_POST), and the result is:

These contents are the data to be submitted by the form.

3. Use CURL to simulate login operations

From the above analysis, the content submitted when logging in is relatively simple. There is no verification code and no hash value verification to prevent cross-domain submission. Then we use CURL to simulate submitting the login form. In fact, a POST HTTP request is sent, and CURL can save the returned cookie into a file. This cookie file will be used in subsequent operations such as sending Fetion.

The code is as follows:

$cookie = dirname(__FILE__).'/cookie.txt';
$post = array(
        'm' => '13700001234',
        'pass' => '123456',
        'loginstatus' => 1,
);

$curl = curl_init('http://f.10086.cn/im/login/inputpasssubmit1.action');
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_COOKIEJAR, $cookie); // 注意这里！保存Cookie
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($post));
$result = curl_exec($curl);
curl_close($curl);

Whether the login is successful, you can determine the value of $result.

4. Bring cookies and send Fetion to yourself

Sending Fetion to yourself is relatively easier than sending it to your friends. There is a dedicated page for this. You can enter from "Home page after login => Information => Send text message to yourself", the address is:
http://f.10086.cn/im/user/sendMsgToMyself.action.

Use the same method as above to analyze the form:

Only one field: msg (text message content)
Submitted action: http://f.10086.cn/im/user/sendMsgToMyselfs.action

Use CURL to send a POST request to this URL, and add the cookie saved above. The following is the code:

$post = array(
        'msg' => 'Hello Fetion',
);

$curl = curl_init('http://f.10086.cn/im/user/sendMsgToMyselfs.action');
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie);        // 注意这里！
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($post));
$result = curl_exec($curl);
curl_close($curl);

You can determine whether the sending is successful based on the returned $result.

5. Before sending Fetion to a friend, first obtain the userid corresponding to the friend’s mobile phone number

Because the form for sending Fetion to friends submits a userid instead of a mobile phone number (the analysis of this form is in the next step), we must find a way to find out the userid corresponding to the mobile phone number. What I am using here is the "Search Friends" function, which is on the homepage after logging in to Fetion, as shown below:

Searching by mobile phone number can get a unique and accurate result, and then we use regular expressions to match the userid in the result page.

First analyze this form:

Sent field: searchText (only one)
Submitted action: http://f.10086.cn/im/index/searchOtherInfoList.action

Use CURL to simulate sending a request, the code is as follows:

$post = array(
        'searchText' => '18700008888',
);

$curl = curl_init('http://f.10086.cn/im/index/searchOtherInfoList.action');
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie);        // 注意这里！
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($post));
$result = curl_exec($curl);
curl_close($curl);

Use regular expressions to get the userid in the result:

preg_match('/toinputMsg\.action\?touserid=(\d+)/si', $result, $matches);
$userid = isset($matches[1]) ? $matches[1] : '';

This block can be used to provide a prompt when the userid cannot be found.

6. Send Fetion to friends

The interface for sending Fetion messages to friends can be entered by clicking on any friend. The form HTML is as shown below:

Analyze this form:

Submitted fields: backUrl, touchTitle, touchTextLength, msg
action: http://f.10086.cn/im/chat/sendMsg.action?touserid=the userid obtained above

The code is as follows:

$post = array(
        'msg' => 'Hello Fetion',
);

$curl = curl_init('http://f.10086.cn/im/chat/sendMsg.action?touserid='.$userid);         // 注意这里！
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie);        // 注意这里！
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($post));
$result = curl_exec($curl);
curl_close($curl);

The above $post only contains one field, because during the experiment I found that other fields are not necessary. You can judge whether the sending is successful or not based on the returned $result.

7. Exit Fetion

如果不退出的话，则登录后的短时间内如果正好有人给你发飞信，就只能在WAP飞信上查看了，而不能自动发到你的手机上。退出的操作比较简单，只是发送了一个GET方式的请求。“退出”的链接可以在登录后首页的右下角看到，如图：

代码如下：

$curl = curl_init('http://f.10086.cn/im/index/logoutsubmit.action');
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie);        // 注意这里！
$result = curl_exec($curl);
curl_close($curl);

8. 总结

通过对以上代码的整理，可以做出一个飞信发送类。也可以做成一个飞信发送的服务，如简单易用的HTTP方式的接口。飞信最大的好处就在于免费，并能实时将信息发送到手机上，可以做一些类似定时短信或监测提醒的功能。

我这里封装成了一个PHP飞信类。
