Question

我已经导入了标题，我已经包含了对象，网址和标题。但它显示错误

键入＆＃39;标题＆＃39;没有与＆＃39; RequestOptionsArgs＆＃39;
类型相同的属性

我的代码：

class myClass
{
    public $inputNumber = 27;
    public $inputArray = array(1, 2, 4);
    public $outputArray = array($inputArray[0]*$inputNumber, $inputArray[1]*$inputNumber, $inputArray[2]*$inputNumber);

    public function printOutput()
    {
        return "1st value is " . $this->outputArray[0] . "<br>";
        return "2nd value is " . $this->outputArray[1] . "<br>";
        return "3rd value is " . $this->outputArray[2] . "<br>";
    }
}

$obj = new myClass;

echo $obj->printOutput();

Answer 1

您需要在Headers中传递RequestOptions，然后再将其传递给post(...)

return this.http.post('http://ip/ex/api/api/JsonServices.php',JSON.stringify(obj),
    new RequestOptions(headers: headers))

Answer 2

标头只是http请求的其中一个选项。尝试使用RequestOptions

import { RequestOptions } from '@angular/router';

getContactData(aplhaNumericId:any){
    let obj = {aplhaNumericId:aplhaNumericId};
    let headers=new Headers();
    headers.append('Content-Type','application/json; charset=utf=8');
    // add this 
    let options = new RequestOptions({headers: headers});
enter code here
    return this.http.post('http://ip/ex/api/api/JsonServices.php', JSON.stringify(obj), options))
        .map((res:Response) => res.json());
}

请注意，这是针对旧的HttpModule

输入＆＃39;标题＆＃39;没有与类型＆＃39; RequestOptionsArgs＆＃39;
