我正在使用Sencha Touch 2.1.0.我正在进行HTTP GET调用.这是一个CORS请求.因此它正在按预期发送Pre-flight HTTP OPTIONS命令.
我在我的服务器上安装了CORS过滤器并进行了配置.来自我的代码的电话一直很顺利,直到昨天.突然间它今天停止加载数据.当我在Chrome中查看网络电话时,我发现OPTIONS方法显示为“已取消加载”
方法：选项
状态文本：“加载已取消”
输入：待定
发起人：Connection.js：319
我第一次配置CORS过滤器时遇到了类似的问题.当我清除浏览器缓存时,它开始工作.这一次,我不确定它为什么突然停止工作.即使我在浏览器中清除缓存和历史记录,也无法修复.
如果我在Firefox中使用HTTPRequestor进行同样的调用,那么它的效果非常好.这是电话.由于保密原因,我屏蔽了网址.
OPTIONS http://myurl/rest/items?_dc=1358304888220&page=1&start=0&limit=25 HTTP/1.1
Access-Control-Request-Method: GET
Origin: http://localhost:8080
Access-Control-Request-Headers: accept, origin, x-requested-with
同样的确切请求给了我一个非常好的HTTPRequestor响应.结果如下：
OPTIONS http://myurl/rest/items?_dc=1358304888220&page=1&start=0&limit=25
Access-Control-Request-Headers: accept, origin, x-requested-with
Access-Control-Request-Method: GET
Origin: http://localhost:8080

在商店中使用Sencha代码进行此调用：
proxy: {
type: ‘ajax’,
method: ‘GET’,
url: ‘http://myurl/rest/items’,
withCredentials: true,
useDefaultXhrHeader: false,
disableCaching: false,
headers: {
“Accept”: “application/json”
},
failure: function(response) {
if (response.timedout) {
Ext.Msg.alert(‘Timeout’, “The server timed out :(“);
} else if (response.aborted) {
Ext.Msg.alert(‘Aborted’, “Looks like you aborted the request”);
} else {
Ext.Msg.alert(‘Bad’, “Something went wrong with your request”);
}
},
success: function(response){
Ext.Msg.alert(response.responseText);
}
},
autoLoad: true,
请帮助我了解如何解决此问题.
