ExtJS Ajax POST vs Proxy POST
提问by Dragos
I am trying to create a grid panel using ExtJS 4.1. It gets its data from the server using an AJAX proxy:
我正在尝试使用 ExtJS 4.1 创建一个网格面板。它使用 AJAX 代理从服务器获取数据：
var store = Ext.create('Ext.data.Store', {
model: 'myModel',
pageSize: pageSize,
proxy: {
type: 'ajax',
url: "../search",
actionMethods: {
create: "POST",
read: "POST",
update: "POST",
destroy: "POST"
},
headers: {
'Content-Type': 'application/json'
},
limitParam: false,
startParam: false,
pageParam: false,
extraParams: JSON.stringify({
rows: pageSize,
role: "Admin",
index: myIndex,
question: searchPhrase
}),
reader: {
type: 'json',
root: 'results.results',
totalProperty: 'numFound',
model: 'myModel'
}
}
});
store.loadPage(1);
but it doesn't seem to work.
但它似乎不起作用。
I get an error message saying that the JSON could not be read. What is more, in Firebug, the sent parameters are not human readable.
我收到一条错误消息，指出无法读取 JSON。更重要的是，在 Firebug 中，发送的参数不是人类可读的。
When I try to make an Ajax call with the same parameters, everything seems to be OK:
当我尝试使用相同的参数进行 Ajax 调用时，似乎一切正常：
Ext.Ajax.request({
url:"../search",
method: "POST",
params: JSON.stringify({
rows: pageSize,
role: "Admin",
index: myIndex,
question: searchPhrase
}),
success: function(){
console.log("ok");
},
failure: function(response, opts){
console.log("failed");
},
headers: {
'Content-Type': 'application/json'
}
});
Even in Firebug, every parameter in the request looks just fine.
即使在 Firebug 中，请求中的每个参数看起来都很好。
What does the framework do different when using a Proxy?
使用代理时，框架有何不同？

I use the following proxy config for the store (ExtJS v6.5.2):
我为商店使用以下代理配置（ExtJS v6.5.2）：
proxy: {
url: 'api/search',
paramsAsJson: true,
actionMethods: {
read: 'POST'
},
type: 'ajax',
reader: {type: 'json'}
},
which sends the parameters as JSON:
它将参数作为 JSON 发送：
{"page":1,"start":0,"limit":25}
