怎样使用php获取复杂json数据并输出

Jun 23, 2016 pm 01:38 PM

这是调用多客服查看当前在线客服时的微信api

返回数据示例(正确时的JSON返回结果):

{    "kf_online_list": [        {            "kf_account": "test1@test",            "status": 1,            "kf_id": "1001",            "auto_accept": 0,            "accepted_case": 1        },        {            "kf_account": "test2@test",            "status": 1,            "kf_id": "1002",            "auto_accept": 0,            "accepted_case": 2        }    ]}
Copy after login


以下是我的代码:

$url_online ="https://api.weixin.qq.com/cgi-bin/customservice/getonlinekflist?access_token={$access_token}";$output_online=file_get_contents($url_online);$jsonStr = json_decode($output_online,true);//读取信息:$content = "客服1:".$jsonStr["kf_online_list"]["kf_account"]."\n在线状态:".$jsonStr["kf_online_list"]["status"]."\n正在接待人数:".$jsonStr["kf_online_list"]["accepted_case"]."\n\n客服2:".$jsonStr["kf_online_list"]["kf_account"]."\n在线状态:".$jsonStr["kf_online_list"]["status"]."\n正在接待人数:".$jsonStr["kf_online_list"]["accepted_case"];?>
Copy after login


我本是希望获得所有的kf_account数据,并返回到微信回话界面,可是这结构有点复杂,还有相同的字段。。。
目前还查询不到结果,我估计是最后获取json的数组写的不对,希望大家帮忙!

file_get_contents对https使用貌似有个警告,你需要打开display errors才能看到
这种问题一步步var_dump上一个变量就可以确定位置了

额知道为啥了,在$

jsonStr["kf_online_list"]["kf_account"]
Copy after login
那两个【】【】中间加上[0]=>
jsonStr["kf_online_list"][0]["kf_account"]
Copy after login
就行了,搜了一晚上啊。。

print_r($data);

看看decode後的????,就不容易?了。

二维数组当做一维访问,当然就不行啦

$status=array('0'=>'不在线','1'=>'电脑在线','2'=>'手机在线','3'=>'电脑手机在线');//$onlinestatus=$jsonStr["kf_online_list"][0]["status"];foreach ($jsonStr['kf_online_list'] as $list){	foreach ($list[kf_account] as $account)	{		foreach ($list[status] as $onlinestatus)		{			$statusStr0=$status[$onlinestatus];			foreach ($list[accepted_case] as $jiedai)			{				$content.="客服:".$account."\n在线状态:"."$statusStr0"."\n正在接待人数:"."$jiedai"."\n\n";			}		}	}}
Copy after login

这是我又写的代码,在foreach ($list[kf_account] as $account)这一行出错了
错误:Invalid argument supplied for foreach() ,这又怎么改呢亲们?

干脆用for循环得了。。

$s =<<< JSON{    "kf_online_list": [        {            "kf_account": "test1@test",            "status": 1,            "kf_id": "1001",            "auto_accept": 0,            "accepted_case": 1        },        {            "kf_account": "test2@test",            "status": 1,            "kf_id": "1002",            "auto_accept": 0,            "accepted_case": 2        }    ]}JSON;$jsonStr = json_decode($s, true);$content = '';foreach($jsonStr['kf_online_list'] as $i=>$item) {  $n = $i + 1;  $content .= "客服{$n}:$item[kf_account]在线状态:$item[status]正在接待人数:$item[accepted_case]";}echo $content;
Copy after login

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.
