發送角度發布請求后，清空$ _POST

Question

我正在以角度發送帖子請求

public saveLead(name: string, phone: string, text: string){
        const params: Lead = new Lead(name,phone,text);

        const headers = {
            'Content-Type':'application/x-www-form-urlencoded'
        };

        return this.http.post('http://127.0.0.1/saveLead', params, {headers});
    }

但是當我在php端檢查$ _POST時，它總是空的

Answer 1

您需要使用HttpParams設置值

const body = new HttpParams()
  .set('name', 'foo')
  .set('phone', 'bar')
  .set('text', 'baz')

並以正文形式發送時， HttpClient將處理標頭

return this.http.post('http://127.0.0.1/saveLead', body)

Answer 2

在您的ts文件中：

public saveLead(name: string, phone: string, text: string){
    const params: Lead = new Lead(name,phone,text);
    return this.http.post('http://127.0.0.1/saveLead', params);
}

在您的php中：

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
$data = json_decode(file_get_contents("php://input"));
var_dump($data)
