前台调用接口出现两次请求解决办法

这里用 vue-resource说明

this.$http.post(‘http://localhost/phpcrud/app.php?action=create‘,{"username":this.customer.name,"phone":this.customer.phone,"email":this.customer.email})

- 后台用的php

if ($action == "create") {$input = file_get_contents("php://input");$json = json_decode($input);$username = $json->username;$email = $json->email;$phone = $json->phone;

$conn->query("set names utf8");$result = $conn->query("insert into `users` (`username`,`email`,`phone`) values(‘$username‘,‘$email‘,‘$phone‘)");if($result){$res["message"] = "插入成功";}else{$res["message"] = "插入失败";}}

在文件头部加上

header(‘Access-Control-Max-Age: 3600‘);
