Getting data from web service using ajax - ajax

Question

I'm trying to get data from a webservice using ajax and POST method.
Ext.Ajax.request({
url: 'http://localhost......',
method:'POST',
success: function(response) { console.log(response.responseText); },
failure: function() { Ext.Msg.alert('Fail'); },
jsonData:{
/*Here I specify my request json*/
}
}
});
The above thing works fine but when i try to mimic the same in EXTJS store it responds with a error
he server responded with a status of 415 (Unsupported Media Type)
EXTJS STORE CODE
Ext.define('IWM.store.JsonTest', {
extend: 'Ext.data.Store',
autoLoad: true,
fields:['Name'],
proxy: {
type: 'ajax',
method : 'POST',
actionMethods: {
create : 'POST',
read : 'POST',
update : 'POST',
destroy: 'POST'
},
jsonData:{
/*JSON */
}
},
url: 'http://localhost......',
success: function(response) { console.log(response.responseText); },
failure:function(){console.log("failed");},
reader: {
type: 'json',
root: 'result',
successProperty: 'success'
}
}
});

Answer 1

First things first, try to change store config as below.
var IWMStore = new Ext.data.JsonStore({
// it seems to me you had forgotten model
model: 'YourDataModel',
autoLoad: true,
proxy: {
type: 'ajax',
url: 'http://your-url-address',
reader: {
type: 'json',
root: 'json-root-value',
idProperty: 'unique-property-in-json-file'
}
}
});
Example JSON value :
// here, ctgMains is the root value, CUST_ASSORT_SECTION_ID is the idProperty
{"ctgMains":[{"CUST_ASSORT_SECTION_ID":"1","CTG_SECTION":"HORECA"},{"CUST_ASSORT_SECTION_ID":"7","CTG_SECTION":"SCO"},{"CUST_ASSORT_SECTION_ID":"3","CTG_SECTION":"TRADER"}]}
Second Attempt :
Try to add headers property in your proxy definition, like below:
proxy: {
type: 'ajax',
url: 'http://your-url-address',
reader: {
type: 'json',
root: 'json-root-value',
idProperty: 'unique-property-in-json-file'
},
headers: {
'Content-type': 'application/json',
'Accept': 'application/json'
}
}

Answer 2

Following on from Oğuz Çelikdemir's answer, you may need to define a json writer for your proxy.
proxy: {
type: 'ajax',
url: 'http://your-url-address',
reader: {
type: 'json',
root: 'json-root-value',
idProperty: 'unique-property-in-json-file'
},
writer: {
type: 'json'
}
}
That should set the json mediatype header (assuming that's what your request is expecting).
