thinkphp 3.1 参数处理问题

Jun 23, 2016 pm 01:27 PM

修改一个已经做好的系统,参数获取方式看不懂,请大神指教
页面提交到Action处理后
结尾部分参数代码是这样写的

echo '{"code":"0","giftPath":"' . $smallIcon . '","giftStyle":"' . $giftinfo['giftStyle'] . '","giftGroup":"' . $giftinfo['sid'] . '","giftType":"' . $giftinfo['giftType'] . '","toUserNo":"' . $emceeinfo['curroomnum'] . '","isGift":"0","giftLocation":"[]","giftIcon":"' . $giftinfo['giftIcon'] . '","giftSwf":"' . $giftinfo['giftSwf'] . '","toUserId":"' . $_REQUEST['toid'] . '","toUserName":"' . $emceeinfo['nickname'] . '","userNo":"' . $_SESSION['roomnum'] . '","giftCount":"' . $_REQUEST['count'] . '","userId":"' . $_SESSION['uid'] . '","giftName":"' . $giftinfo['giftname'] . '","userName":"' . $_SESSION['nickname'] . '","giftId":"' . $giftinfo['id'] . '"}';exit;
Copy after login

然后处理参数是在JS里完成的
var obj_box=data["ct"]; //这里不明白这个data["ct"]代表什么,查找整个项目也找不到相关代码obj_box=obj_box.replace(/\+/g,"%20");obj_box=evalJSON(decodeURIComponent(obj_box));var giftIcon=obj_box.giftIcon,giftNum=obj_box.giftCount,giftName=obj_box.giftName,giftimg='',isGift=obj_box.isGift || 0,ugood=obj_box["userNo"],uid=obj_box["userId"],uname=decodeURIComponent(obj_box["userName"]),cugood=this.chatgnum(obj_box["userNo"]),tougood=obj_box["toUserNo"],touid=obj_box["toUserId"],touname=decodeURIComponent(obj_box['toUserName']),tocugood=this.chatgnum(obj_box["toUserNo"]),gifttop=parseInt($('#gift_history li').size()) || 0;
Copy after login

上面这里也不明白,obj_box.giftIcon 和obj_box["userName"] 是一样的么?
最后,最大的问题来了,我在ACTION末端参数中加了一个参数,在ACTION里测试是有数值的,但是就是传不到JS里,不知道哪里出的问题

zjcoin这个就是自己加的参数

echo '{"code":"0","zjcoin":"' . $zjcoin . '","giftPath":"' . $smallIcon . '","giftStyle":"' . $giftinfo['giftStyle'] . '","giftGroup":"' . $giftinfo['sid'] . '","giftType":"' . $giftinfo['giftType'] . '","toUserNo":"' . $emceeinfo['curroomnum'] . '","isGift":"0","giftLocation":"[]","giftIcon":"' . $giftinfo['giftIcon'] . '","giftSwf":"' . $giftinfo['giftSwf'] . '","toUserId":"' . $_REQUEST['toid'] . '","toUserName":"' . $emceeinfo['nickname'] . '","userNo":"' . $_SESSION['roomnum'] . '","giftCount":"' . $_REQUEST['count'] . '","userId":"' . $_SESSION['uid'] . '","giftName":"' . $giftinfo['giftname'] . '","userName":"' . $_SESSION['nickname'] . '","giftId":"' . $giftinfo['id'] . '"}';
Copy after login

var zjcoin = obj_box["zjcoin"];//或者var zjcoin = obj_box.zjcoin;都无法获得值,提示未定义
Copy after login

这个php代码是ajax里后台向页面返回值的,在前台取json的值,看看js 的ajax是怎么取json的值就OK

能给一段正常json取值的代码么?我好对比一下。
在这段代码中,唯一看到跟取值有关的就是一句 var obj_box=data["ct"]; 这个data从哪来的 "ct"又代表什么,完全没有头绪

查了一些json的资料,例如:

function showJSON() { var user = { "username":"andy", "age":20, "info": { "tel": "123456", "cellphone": "98765"}, "address": [ {"city":"beijing","postcode":"222333"}, {"city":"newyork","postcode":"555666"} ] } alert(user.username); alert(user.age); alert(user.info.cellphone); alert(user.address[0].city); alert(user.address[0].postcode); user.username = "Tom"; alert(user.username); } 
Copy after login
Copy after login

上例代码中,至少还有一个var user={ ... } 来存储json的代码,但是直接{...}这样编写的话,又该如何取值?

遍历获取
user[0].username

5楼的朋友没明白我的问题,
我这样说吧
在 thinkphp3.1的框架下
tpl中的 show.html 页面中进行了一些动作的提交,
提交到了lib中的showAction.class.php的其中一个方法sendMsg()代码如下
public funciton sendMsg()
{
//处理代码....忽略...

echo '{"code":"0","msg":"message1"}'; //这一段就是返回给Html信息的代码了,直接echo{参数...}
exit;
}
取值的时候,是在Javascript中的
var obj_box=data["ct"];
按照原来的代码,
obj_box.code 或者 obj_box["code"]都能取到值,可是我自己手动新增一个参数的话,就无法取值了,查过在action中是有值的,那么就是传输中出的问题,不知道大家有没有用过这种编写方式?

你自己增加的参数是怎么写的?

你自己增加的参数是怎么写的?


原先的action中的代码是
public funciton sendMsg()
{
//处理代码....忽略...

echo '{"code":"0","giftPath":"' . $smallIcon . '"......}';
exit;
}
增加参数后代码是
public funciton sendMsg()
{
//处理代码....忽略...

echo '{"code":"0", “zjcoin”:"'.$zjcoin.'","giftPath":"' . $smallIcon . '"......}';//红色的部分是增加的参数
exit;
}
在JS中,其他的参数可以用obj_box[""]来获取,可我自己添加的这个参数就是取不到,数值是有的,添加到数据库都看到值了。

又有了新的发现,另外一个js文件中

var GiftCtrl={    sendGift:function(){    var url="/index.php/Show/show_sendGift/eid/"+_show.emceeId+"/toid/"+GiftCtrl.gift_to_id+"/count/"+giftNum+"/gid/"+GiftCtrl.gift_id+"/t/"+Math.random();    var tmpgid=GiftCtrl.gift_id;    GiftCtrl.clearGiftCfg();    $.getJSON(url,function(json){		if(json){			if(json.code==0){				 GiftCtrl.gift_to_id=_show.emceeId;				 $('#giftto').html(_show.emceeNick);				Chat.getUserBalance();//用户秀币更新				Dom.$swfId("flashCallChat")._chatToSocket(0, 2, '{"_method_":"sendGift","giftPath":"' + json.giftPath + '","giftStyle":"' + json.giftStyle + '","giftGroup":"' + json.giftGroup + '","giftType":"' + json.giftType + '","toUserNo":"' + json.toUserNo + '","isGift":"' + json.isGift + '","giftLocation":"' + json.giftLocation + '","giftIcon":"' + json.giftIcon + '","giftSwf":"' + json.giftSwf + '","toUserId":"' + json.toUserId + '","toUserName":"' + json.toUserName + '","userNo":"' + json.userNo + '","giftCount":"' + json.giftCount + '","userId":"' + json.userId + '","giftName":"' + json.giftName + '","userName":"' + json.userName + '","giftId":"' + json.giftId + '","zjcoin":"' + json.zjcoin + '"}');//这一段参数的顺序跟action中的顺序一样,末尾也加了zjcoin,结果还是无法获取	}}
Copy after login

最后那一段参数的顺序跟action中的顺序一样,我在末尾也加了zjcoin,结果还是无法获取

此楼,30分即可.

此楼,30分即可.


请指教?

终于知道原因了,原来参数传递还要通过一个swf文件, 网上下了几个能编辑swf代码的工具,能打开修改,但是一保存就弹出错误,不知道哪位大神有这样的工具,能编辑swf里面代码的工具

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
