Zend Framework动作助手Json用法实例分析_php实例

本文实例讲述了Zend Framework动作助手Json用法。分享给大家供大家参考,具体如下:

Json的使用较简单,以下是文档给出的用法:

Json 用来解码和发送 JSON 响应;

当处理期望数据表响应的 AJAX 请求,JSON 响应迅速变成选择的响应。

JSON 可以立即在客户端被解析,从而快速执行。

JSON 动作助手完成以下任务:

如果布局是打开(enabled)的,则关闭(disable)它。

如果视图解析器(ViewRenderer)是打开的,则关闭它。

设置 'Content-Type' 响应头为 'application/json'。

缺省地,不需要等待动作执行完成,立即返回响应。

用法很简单:或者把它作为助手代理的方法来调用,或者调用 encodeJson() 和 sendJson() 方法的其中之一:

class FooController extends Zend_Controller_Action
{
  public function barAction()
  {
    // do some processing...
    // Send the JSON response:
    $this->_helper->json($data);
    // or...
    $this->_helper->json->sendJson($data);
    // or retrieve the json:
    $json = $this->_helper->json->encodeJson($data);
  }
}

Note: 保持布局 (Keeping Layouts)

如果你为 JSON 响应有分离的布局 - 也许把 JSON 封装到一些上下文 - 在 JSON 助手的每个方法接受第二个可选的参数:打开或关闭布局的 flag ,传递一个布尔 true 值将使布局保持打开:

class FooController extends Zend_Controller_Action
{
  public function barAction()
  {
    // Retrieve the json, keeping layouts:
    $json = $this->_helper->json->encodeJson($data, true);
  }
}

Copy after login

Combination of golang WebSocket and JSON: realizing data transmission and parsing Combination of golang WebSocket and JSON: realizing data transmission and parsing Dec 17, 2023 pm 03:06 PM

The combination of golangWebSocket and JSON: realizing data transmission and parsing In modern Web development, real-time data transmission is becoming more and more important. WebSocket is a protocol used to achieve two-way communication. Unlike the traditional HTTP request-response model, WebSocket allows the server to actively push data to the client. JSON (JavaScriptObjectNotation) is a lightweight format for data exchange that is concise and easy to read.

What is the difference between MySQL5.7 and MySQL8.0? What is the difference between MySQL5.7 and MySQL8.0? Feb 19, 2024 am 11:21 AM

MySQL5.7 and MySQL8.0 are two different MySQL database versions. There are some main differences between them: Performance improvements: MySQL8.0 has some performance improvements compared to MySQL5.7. These include better query optimizers, more efficient query execution plan generation, better indexing algorithms and parallel queries, etc. These improvements can improve query performance and overall system performance. JSON support: MySQL 8.0 introduces native support for JSON data type, including storage, query and indexing of JSON data. This makes processing and manipulating JSON data in MySQL more convenient and efficient. Transaction features: MySQL8.0 introduces some new transaction features, such as atomic

How to exclude a field from JSON using @Expose annotation in Java? How to exclude a field from JSON using @Expose annotation in Java? Sep 16, 2023 pm 09:49 PM

The Gson@Expose annotation can be used to mark whether a field is exposed (contained or not) for serialization or deserialization. The @Expose annotation can take two parameters, each parameter is a boolean value and can take the value true or false. In order for GSON to react to the @Expose annotation, we have to create a Gson instance using the GsonBuilder class and need to call the excludeFieldsWithoutExposeAnnotation() method, which configures Gson to exclude all fields without Expose annotation from serialization or deserialization. Syntax publicGsonBuilderexclud
