因此，我大体上同意，更好的解决方案是确保服务器只返回JSON，不过这是通过客户端Javascript实现的一种快速方法，如@Barmer所建议的那样，将html解析到DOM，获取body中的文本childNode并在其上运行JSONParse。在var responseStr = '' +

'

' +

'

503 Service Unavailable' +

'' +

'

' +

'

503 Service Unavailable

' +

'{' +

' "status": "object-specific error",' +

' "payload": {' +

' "Message": "Unable to list resources",' +

' "HTTP Method": "GET",' +

' "URI": "api/myManager/1.0/Node",' +

' "Operation": "LIST",' +

' "Object": {' +

' "Name": "myManager.Node",' +

' "Interface": "Node"' +

' },' +

' "Version": {' +

' "Major": 1,' +

' "Minor": 0' +

' }' +

' }' +

'}
' +

'' +

'';

var parser = new DOMParser();

var doc = parser.parseFromString(responseStr, "text/html");

var items = doc.body.getElementsByTagName("*");

var json_obj;

for (var i = 0, len = doc.body.childNodes.length; i < len; i++) {

if (doc.body.childNodes[i].nodeName == "#text") {

json_obj = JSON.parse(doc.body.childNodes[i].data);

break;

}

}

// You can access json directly now e.g.

console.log(json_obj.status);

console.log(json_obj.payload['HTTP Method']);
