In yii2.0, it prompts csrf that the data you submitted cannot be verified.

In yii, we often encounter the situation that "the data you submitted cannot be verified". This is because yii has a csrf verification.

Just turn off csrf verification.

1. Add

public $enableCsrfValidation = false;

to the controller 2. Add a hidden field to the form

However, in the advanced version, there will be front and backends, that is The name is not necessarily _csrf, it may be _csrf-backend or _csrf-frontend, etc. The field name of

_csrf must be consistent with the current page.

3. Ajax submission

The ajax library used here is axios ajax

axios({ url: url, headers:{ '' : '  request -> csrfToken; ?>' // _csrf验证 }, data: postData, }).then(response => { // 请求成功 回调 }).catch(error => { // 请求失败 回调 })
