发送角度发布请求后，清空$ _POST

Question

我正在以角度发送帖子请求

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});
    }

但是当我在php端检查$ _POST时，它总是空的

Answer 1

您需要使用HttpParams设置值

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

并以正文形式发送时， HttpClient将处理标头

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)
