xmlhttpRequest状态在phonegap中返回0 [英] xmlhttpRequest status returns 0 in phonegap

问题描述

我在phonegap制作一个混合应用程序。我使用xmlhttpRequest.My解析json问题是，当我尝试获取浏览器上的响应，http.status是200和响应是确定，但是当我尝试运行Android设备上的代码，然后http.readystate出来是4但http.status变为0，我得到空响应。我搜索了许多链接，并使用CORPS也，但问题仍然存在。任何一个可以告诉我，我怎么能得到http.status作为200在Android设备？下面是我的代码。

I am making a hybrid app in phonegap. I am parsing json using xmlhttpRequest.My Problem is that when i try to fetch the response on browser,http.status is 200 and response is ok but when i try to run the code on android device then http.readystate comes out to be 4 but http.status comes 0 and i get empty response .I have searched many links and used CORPS also but the problem still persist. Can any one please tell me that how can i get the http.status as 200 on android device? Below is my code.

function myFunction(){
 alert("inside function");
 var http;
 if (window.XMLHttpRequest)
 {// code for IE7+, Firefox, Chrome, Opera, Safari
    http = new XMLHttpRequest();
    alert(" inside if");
 }
 else
 {
     // code for IE6, IE5
     alert("inside else");
     http = new ActiveXObject("Microsoft.XMLHTTP");
 }
    var url = "http://localserver/abc/v1/signup";
    var params = "email=adsefgbbgtrhtrh &password=tyujkuykyuil &phone=95876894760458 ";
    http.open("POST", url, true);
    http.setRequestHeader("Content-type","application/x-www-form-urlencoded");
    http.onreadystatechange = function() {
        //Call a function when the state changes.
        if(http.readyState == 4) {
            alert("inside if"+http.responseText); //Here i get empty text
        }
        alert("inside if function"+http.status+"state"+http.readyState);  //Here http.status is 0 and readystate is 4 
    }
    http.send(params);
    response.writeHead(200, {
        'Content-Type': 'text/html',
        'Access-Control-Allow-Origin' : '*'});
    alert("ouside if"+http.status+"state"+http.readyState);}

在服务器端我已经添加到行：

On server side i have added to lines:

header('Access-Control-Allow-Origin:*');header('Content-Type: application/x-www-form-urlencoded');

我还在config.xml中设置了访问源。

I have also set the access origin in config.xml

<access origin="*"  subdomains="true"/>
<access origin="http://localserverIP*" subdomains="true"/>
<access origin="http://google.com" subdomains="true"/>

请帮助！

推荐答案

当我使用XMLHttpRequest时，我有同样的问题。所以我使用$ .ajax和一切工作。我知道$ .ajax是基于XMLHttpRequest，但它的工作和开发更容易。我希望它帮助，即使答案是有点晚了。 =）

I had the same problem when I used XMLHttpRequest. So I used $.ajax and everything was working. I know that $.ajax is based on XMLHttpRequest, but it works and the development is more easy. I hope it helps even if the answer is a bit late. =)
