在yii2中访问发布json数据时出错 [英] Error in accessing post json data in yii2
问题描述
我使用ajax请求将数据传递到yii2,但我不断收到500错误
Am passing data to yii2 using ajax request but i keep on getting a 500 error
这是ajax请求代码:
This is the ajax request code:
<?php
$script = <<< JS
$('form#forward_pr').on('beforeSubmit', function(e){
var keys = $('#grid').yiiGridView('getSelectedRows');
$.post({
url: "forwardpr", // your controller action
dataType: 'json',
data: {keylist: keys},
success: function(data) {
alert('I did it! Processed checked rows.')
},
error: function(err){
console.log("server error");
}
});
return false;
} ) ;
JS;
$this->registerJS($script);
?>
当我执行console.log(keys)时,返回
When i do console.log(keys) this returns
[0, 1]
这是我的控制器代码:
if (Yii::$app->request->post()) {
echo $post = json_encode($_POST['keys']);
if (isset($_POST['keylist'])) {
$keys = \yii\helpers\Json::decode($_POST['keylist']);
print_r($keys);
}else{
echo "1";
}
上面的代码总是执行发布请求的错误部分,这可能是什么错误;
The above always executes the error part of post request, What could be wrong;
推荐答案
您正在将JSON发送为编码(发布)数据主体,而不是键值对.因此,您的方法无法以这种方式工作.
You are sending your JSON as encoded (post) data body, not key value pairs. So your approach is not working this way.
有两种方法可以解决此问题:
There are two options to fix this:
- 将您的控制器重构为 RESTful服务
- 在控制器中使用JSON正文而不是POST参数
从长远来看,第一个选项是首选,但第二个选项作为快速修复很简单.
While the first option is preferred in the long run, the second option is pretty simple as a quick fix.
首先,请确保配置您的应用程序以解析JSON正文内容.在 config.php
中将其添加到 components
数组中:
First, make sure you configure your app to parse JSON body conten.
IN config.php
add this to the components
array:
'request' => [
'parsers' => [
'application/json' => 'yii\web\JsonParser',
]
]
然后在您的控制器中使用它来获取JSON参数:
Then in your controller use this to get the JSON parameters:
$model->load(Yii::$app->getRequest()->getBodyParams());
