Sending Http POST Request through Rest API in Javascript
提问by Amir
I am trying to send an Http post request to parse.com server through Rest API keys. Not sure if I am doing it right as below. The following is my whole script and makes a button which should trigger the post request in a simple HTML page.
我正在尝试通过 Rest API 密钥向 parse.com 服务器发送 Http post 请求。不知道我是否按照下面的方式做对了。以下是我的整个脚本，并制作了一个按钮，该按钮应该在一个简单的 HTML 页面中触发发布请求。
<input id="clickMe" type="button" value="clickme" onclick="doFunction();" />
<script>
xmlhttp = new XMLHttpRequest();
var url = "https://api.parse.com/1/classes/english";
xmlhttp.open("POST", url, true);
xmlhttp.setRequestHeader("Content-type", "application/json");
xmlhttp.setRequestHeader("X-Parse-Application-Id", "VnxVYV8ndyp6hE7FlPxBdXdhxTCmxX1111111");
xmlhttp.setRequestHeader("X-Parse-REST-API-Key","6QzJ0FRSPIhXbEziFFPs7JvH1l11111111");
xmlhttp.onreadystatechange = function () { //Call a function when the state changes.
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
alert(xmlhttp.responseText);
}
}
var parameters = {
"ephrase": "english",
"pphrase": "farsi",
"nvote": 0,
"yvote": 0
};
// Neither was accepted when I set with parameters="username=myname"+"&password=mypass" as the server may not accept that
function doFunction() {
xmlhttp.send(parameters);
}
</script>

xmlhttp.send(parameters);
^^^^^^^^^^
That needs to be a string, but it is an object, so will be converted to the string: "[object Object]".
那需要是一个字符串，但它是一个对象，所以将被转换为字符串："[object Object]"。
You need to convert the data to the proper encoding first.
您需要先将数据转换为正确的编码。
You've said:
你说过：
xmlhttp.setRequestHeader("Content-type", "application/json");
so you can use JSON.stringify(parameters)for that.
所以你可以使用JSON.stringify(parameters)它。
