ExtJS AJAX获取原始响应文本

I am making an AJAX call in ExtJS 4, which some users have reported fails without showing any error messages. Looking at the response object, the code is 0 and the responseText is blank. My best guess is that the server is for some reason returning something that is not properly formatted as JSON.

我正在ExtJS 4中进行AJAX调用,一些用户报告失败但没有显示任何错误消息。查看响应对象,代码为0,responseText为空。我最好的猜测是,服务器由于某种原因返回了一些格式不正确的JSON。

How can I get the raw response text if it is not formatted as JSON?

如果原始响应文本未格式化为JSON,如何获取原始响应文本?

You could override the Ext.data.Connection to grab the data when it is returned, and before it is processed in any way. I would guess that Andrei is right with his diagnosis, but if you aren't so sure...

您可以覆盖Ext.data.Connection以在返回数据时以及在以任何方式处理数据之前获取数据。我猜安德烈对他的诊断是正确的,但如果你不太确定......

You should be able to get everything you need like this:

你应该能够得到你需要的一切:

Ext.Ajax.request({
url : 'someUrl',
listeners : {
    requestexception : function( conn, response, options, eOpts ){
    console.log(response);
    }

}
});

Status 0 should give you Communication Failure in response.operation.error.statusText ... just console.log(response) and start looking for the significant property for you I wouldn't go to raw unless no other option.

状态0应该在response.operation.error.statusText中给你通信失败...只是console.log(响应)并开始为你寻找重要属性我不会去原始,除非没有其他选项。
