将值从 ionic 传递到 php curl

Question

我正在尝试学习curl。我需要将变量从 Ionic 传递到 PHP 文件。这是到目前为止的代码，我想编写传递的变量而不是硬编码值"Saurabh\"Ionic / Angular .ts 代码  create_person_name(){  console.log(this.val1);  console.log('inside function');  let empname= this.val1; //let msg = "Thank you for trusting KRANTI PRODUCTS. Your Complaint Number is: " + this.ticketnumber;  let params = '&empname='+this.val1;  var headers = new Headers();  headers.append('Content-Type', 'application/x-www-form-urlencoded');  return this._http.post("https://example.com/" + "create-person-name.php", params, {headers: headers})  .map((response: Response) => response.json());  }PHP我该如何提及&empname来代替"Saurabh\"？<?php$curl = curl_init();curl_setopt_array($curl, array(  CURLOPT_URL => "https://centralindia.api.cognitive.microsoft.com/face/v1.0/persongroups/2/persons",  CURLOPT_RETURNTRANSFER => true,  CURLOPT_ENCODING => "",  CURLOPT_MAXREDIRS => 10,  CURLOPT_TIMEOUT => 30,  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,  CURLOPT_CUSTOMREQUEST => "POST",  CURLOPT_POSTFIELDS => "{  \r\n    \"name\" : \"Saurabh\",  \r\n    \"userData\" : \"TCO\" ,\r\n    \"recognitionModel\": \"recognition_02\"\r\n}",

Answer 1

像这样更新帖子字段...

"{  \r\n    \"name\" : \"{$_POST['empname']}\",  \r\n    \"userData\" : \"TCO\" ,\r\n    \"recognitionModel\": \"recognition_02\"\r\n}",

您可以使用数组构建它，然后对其进行 json_encode...

$fields = array(

    'name' => $_POST['empname'],

    'userData' => 'TCO',

    'recognitionModel' => 'recognition_02',

);

然后更新curl数组

CURLOPT_POSTFIELDS => json_encode($fields)
