Titanium：主机连接时出现 TiHttpClient 错误

Question

描述：我想通过 POST 请求连接到服务器。我的方法，发布请求：

function loginClick(e) {
    var url = "http://...";
    var xhr = Ti.Network.createHTTPClient({
        onload: function (e) { // this function is called when data is returned from the server and available for use
            // this.responseText holds the raw text return of the message (used for text/JSON)
            // this.responseXML holds any returned XML (including SOAP)
            // this.responseData holds any returned binary data
            Ti.API.debug(this.responseText);
            alert(xhr.responseText);
        },
        onerror: function (e) { // this function is called when an error occurs, including a timeout
            Ti.API.debug(e.error);
            alert(e.toString);
        },
        timeout: 5000 /* in milliseconds */
    });
    xhr.autoEncodeUrl = false;
    var params = {
        email: $.email.value,
        password: $.password.value
    };
    xhr.open('POST', url);
    xhr.send(params); // request is actually sent with this statement 
    Ti.API.info(xhr.responseText);
};

但我不能这样做，因为收到奇怪的消息。我把它放在日志中。此外，我做了另一个请求，他们成功地工作了。 日志：

[ERROR] : TiHttpClient: (TiHttpClient-1) [3529,3529] HTTP Error (org.apache.http.client.HttpResponseException): Not Found

我在发送请求时使用 JSON.stringify(params) 解决了这个问题：

function loginClick(e)
{
var url = 'http://...';
var xhr = Ti.Network.createHTTPClient({
    onload: function(e) {
        // this function is called when data is returned from the server and available for use
        // this.responseText holds the raw text return of the message (used for text/JSON)
        // this.responseXML holds any returned XML (including SOAP)
        // this.responseData holds any returned binary data
        Ti.API.debug(this.responseText);
        alert(xhr.responseText);
    },
    onerror: function(e) {
        // this function is called when an error occurs, including a timeout
        Ti.API.debug(e.error);
        alert(this.status);
        alert("error" + e.toString);
    },
    timeout:5000  /* in milliseconds */
});
xhr.autoEncodeUrl = false;
var params = {  
    'email': $.email.value,  
    'password' :$.password.value
};

xhr.open('POST', url);
xhr.setRequestHeader("Content-Type", "application/json; charset=utf-8");
xhr.send(JSON.stringify(params)); // request is actually sent with this statement

};

“未找到”异常是有道理的。我尝试使用 CURL 进行 POST 以证明这不是由 Titanium 引起的。您的网址错误。
