Question

我想使用javascript对外部网址执行POST请求。目前我使用php服务器端发送请求

$data = array(
        'TokenExID' => $tokenex_id,
        'APIKey' => $api_key,
        'EcryptedData' => $encrypted_data,
        'TokenScheme' => 4
    );
    $ch = curl_init("https://api.testone.com/TokenServices.svc/REST/TokenizeFromEncryptedValue");

        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
                                        'Content-Type: application/json', //                  
                                        'Accept: application/json')       //
                                        );
           curl_setopt($ch, CURLOPT_POST, 1);
           curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
           curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
           curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

我想在javascript中使用相同的代码。

var url =＆＃34; https://api.testone.com/TokenServices.svc/REST/TokenizeFromEncryptedValue＆＃34 ;;

var params = "abcd";
http.open("POST", url, true);

//Send the proper header information along with the request
http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.setRequestHeader("Content-length", params.length);
http.setRequestHeader("Connection", "close");

http.onreadystatechange = function() {//Call a function when the state changes.
    if(http.readyState == 4 && http.status == 200) {
        alert(http.responseText);
    }
}

http.send(params);

我得到了这个javascript示例代码，但我不知道怎么做。我是javascript的新手，但无法找到办法做到这一点。可以帮我一个人吗？

如果您是javascript的新手，我强烈建议您使用jQuery，这将大大减轻您的工作量。在线搜索如何将其包含在您的页面中，然后这是代码。

var data = {
    param1: "value1",
    param2: "value2"
    // add here more params id needed followinf the same model

};

$.ajax({
    type: "POST",
    url: 'http://www.myrestserver.com/api',
    data: data,
    success: success
});

function success(result) {
    // do something here if the call is successful
    alert(result);
}
