[英]Unable to get Java Response in Ajax with dataType: “jsonp” but dataType: “text” Works
[英]Get response text from a JSONP request in Ext / Java Application
我正在尝试将Java REST服务连接到ExtJs JSONP请求,但是即使执行了Java方法,我也无法获得响应测试。 这是我正在尝试的:
Java代码:
@Path("/hello")
public class Hello {
@GET
@Produces("text/javascript") // have also tried application/json
public String sayJsonHello(@QueryParam("_dc") String dcIdentifier, @QueryParam("callback") String callback) {
System.out.println(callback);
callback += "({\"success\":true, \"msj\":" + "\"" + "Exitoooo!" + "\" });";
System.out.println(callback);
return callback;
}
}
ExtJs代码:
Ext.data.JsonP.request({
url: "http://10.1.50.66:7001/Simulador/webresources/hello",
params: {
},
callback: function (response) {
console.log(response); //true
console.log(response.result); //undefined
console.log(response.responseText); //undefined
console.log(response.success); // undefined
if (response.success === true) {
Ext.Msg.alert('Link Shortened', response.msj, Ext.emptyFn);
} else { // entering here :( why ?
Ext.Msg.alert('Error', response.msj, Ext.emptyFn);
}
}
});
响应打印为真,其他所有未定义:(
回调看起来像这样Ext.data.JsonP.callback1({"success":true, "msj":"exito"})
任何想法可能有什么问题吗?
好的,这对我有用:
Ext.data.JsonP.request({
url: "http://10.1.50.66:7001/Simulador/webresources/hello",
callbackKey: 'callback1',
params: {
},
success : function(response) {
console.log("Spiffing, everything worked");
// success property
console.log(response.success);
// result property
console.log(response.result);
console.log(response.msj);
},
failure: function(response) {
console.log(response);
Ext.Msg.alert('Error', 'Please try again.', Ext.emptyFn);
}
});
