Javascript iron ajax未将输入数据发布到php

聚合物元素脚本的一部分：

<content>
            <iron-ajax id="plWhois" method="POST" body='{"helper":"plugin", "func":"_pluginsInitAjax", "params":{"domain": "domain", "request_type": "taken"}}' handle-as="json" on-response="handleResponse" debounce-duration="300"></iron-ajax>
            <paper-card heading="Begin the search for your perfect domain name..." image="themes/custom_components/apps/pl-whois/img/who-is.jpg" center>
                <div class="card-content">
                    <paper-input id="plWhoisSearchBtn" type="search" placeholder="e.g. mydomain.com">
                        <iron-icon prefix icon="search"></<iron-icon>
                    </paper-input>
                </div>
                <div class="card-actions s-t">
                    <paper-button on-click="domainAvailability">Search</paper-button>
                    <paper-button>Transfer</paper-button>
                </div>

                </div>
            </paper-card>
  </content>

        // element registration

                    value: ''
                }
        },
            domainAvailability: function () {
                var domain = this.$.plWhoisSearchBtn.value;

                this.$.plWhois.url = "ajax.php";
                /*this.$.plWhois.body = {"helper":"plugin", "func":"_pluginsInitAjax", "params":{"domain": domain, "request_type": "taken"}};
                */
                this.$.plWhois.generateRequest();
            },
            handleResponse: function(e) {
                console.log(e.detail.response);
            }
        });

看起来您的
调用缺少
url
属性。
我仍然遇到同样的问题，看起来像是一个bug什么的，（动态导入的脚本在iron ajax请求期间不会发送post数据）

因此，作为一种解决方法，从元素的属性中获取url和主体值，然后将它们绑定到iron ajax似乎是可行的：

Iron ajax:

{{url}”body=”{{params}”在response=“handleResponse”debounce duration=“300”上处理为=“json”

此脚本将属性添加到my元素中，并触发iron请求：

现在这就是我导入的元素的外观（部分）：

//导入
用添加URL的脚本标记编辑了我的问题有问题的网站是（），在输入和点击搜索中输入一个单词，它不会发送输入数据这里是元素的完整脚本（），看起来Ajax请求完成了，因为HandlerResponse方法打印出一个对象：{err:“helper类必须是string类型，（NULL）given！”}。我建议您使用类似Postman的工具调试ajax端点，以查明问题所在。
var domain = this.$.plWhoisSearchBtn.value;

this.url = 'ajax.php';
this.params = '{"helper":"plugin", "params":{"0":"whoapi_dot_com", "1":"_test", "2":{"0": "'+domain+'", "1": "taken"}}}';     
this.$.plWhois.generateRequest();
