将 GWT 输入发布到 PHP 页面

发布于 2024-12-11 06:05:59 字数 179 浏览 0 评论 0原文

我有一个带有输入的 GWT 应用程序（例如姓名、地址、电子邮件）。用户输入所有必填字段并按提交按钮后，PHP 页面将显示来自 GWT 应用程序的输入。如何将我的 GWT 应用程序连接到 php？我现在正在使用请求生成器。我是否仍然需要使用 XML 将 GWT 输入传递给 PHP？请帮忙。我刚刚开始在这里学习GWT。

提前致谢。

实际上，您不需要 RequestBuilder 来完成类似的事情。
如果您重定向到 PHP url 并将输入附加为 GET 参数就足够了。
例如，在点击处理程序中，您可以执行类似的操作：

submitButton.addClickHandler(new ClickHandler() {
    public void onClick(ClickEvent event) {
        String linkURL = "somePage.php?name="+name+"&address="+address+"&email="+email;
         Window.Location.assign(linkURL);
    }
});

然后在 PHP 页面中，您可以通过以下方式检索参数：

$name = $_GET['name'];
$address = $_GET['address'];
$email = $_GET['email'];

更新

如果您想使用 RequetBuilder，则必须执行类似的操作：

submitButton.addClickHandler(new ClickHandler() {
    public void onClick(ClickEvent event) {
        RequestBuilder request = new RequestBuilder(POST,PHP_URL);
        JSONObject jsonValue = new JSONObject();
        jsonValue.put("name", new JSONString(name));
        jsonValue.put("address", new JSONString(address));
        jsonValue.put("email", new JSONString(email));
        request.setHeader("Content-Type", "application/json");
        request.sendRequest(jsonValue.toString(),new RequestCallback() {
            @Override
            public void onResponseReceived(Request request, Response response) {
                if (200 == response.getStatusCode()) {
                     //retrieve a uniqueid or so and redirect to the PHP page which displays the infos
                } else {
                   // displayError("Couldn't retrieve 

                }
            }

            @Override
            public void onError(Request request, Throwable exception) {
                 //displayError("Couldn't retrieve JSON");
            }
         });

    }
});

在服务器上，您只需访问全局 $_POST 变量即可获取值：

$name = @_POST['name']

You actually don't need RequestBuilder for something like that.
It would be sufficient if you redirect to the PHP url and append your inputs as GET parameters.
So for example in the click handler you can do something like that:

submitButton.addClickHandler(new ClickHandler() {
    public void onClick(ClickEvent event) {
        String linkURL = "somePage.php?name="+name+"&address="+address+"&email="+email;
         Window.Location.assign(linkURL);
    }
});

and then in the PHP page you can retrieve the parameters in this way:

$name = $_GET['name'];
$address = $_GET['address'];
$email = $_GET['email'];

Update

If you want to use RequetBuilder you have to do something like that:

submitButton.addClickHandler(new ClickHandler() {
    public void onClick(ClickEvent event) {
        RequestBuilder request = new RequestBuilder(POST,PHP_URL);
        JSONObject jsonValue = new JSONObject();
        jsonValue.put("name", new JSONString(name));
        jsonValue.put("address", new JSONString(address));
        jsonValue.put("email", new JSONString(email));
        request.setHeader("Content-Type", "application/json");
        request.sendRequest(jsonValue.toString(),new RequestCallback() {
            @Override
            public void onResponseReceived(Request request, Response response) {
                if (200 == response.getStatusCode()) {
                     //retrieve a uniqueid or so and redirect to the PHP page which displays the infos
                } else {
                   // displayError("Couldn't retrieve 

                }
            }

            @Override
            public void onError(Request request, Throwable exception) {
                 //displayError("Couldn't retrieve JSON");
            }
         });

    }
});

On the server you just access the global $_POST variable to get the values:
