用jquery的ajax组件可以很快实现js发送请求。参考以下JS代码:
<script>
$(function(){
var url = "http://abc.com"//你的请求url
//发起get请求
$.get(url, function(res){
console.log('ajax_get========', res)
},'json')
})
//发起post请求
var postdata = {
'id':'123'
}//post提交的参数
$.post(url, postdata, function(res){
console.log('ajax_get========', res)
},'json')
})
</script>
json数据格式解析我自己分为两种;一种是普通的,一种是带有数组形式的;
普通形式的:
服务器端返回的json数据格式如下:
复制代码代码如下:
{"userbean":{"Uid":"100196","Showname":"\u75af\u72c2\u7684\u7334\u5b50","Avtar":null,"State":1}}
分析代码如下:
复制代码代码如下:
// TODO 状态处理 500 200
int res = 0
res = httpClient.execute(httpPost).getStatusLine().getStatusCode()
if (res == 200) {
/*
* 当返回码为200时,做处理
* 得到服务器端返回json数据,并做处理
* */
HttpResponse httpResponse = httpClient.execute(httpPost)
StringBuilder builder = new StringBuilder()
BufferedReader bufferedReader2 = new BufferedReader(
new InputStreamReader(httpResponse.getEntity().getContent()))
String str2 = ""
for (String s = bufferedReader2.readLine()s != nulls = bufferedReader2
.readLine()) {
builder.append(s)
}
Log.i("cat", ">>>>>>" + builder.toString())
JSONObject jsonObject = new JSONObject(builder.toString())
.getJSONObject("userbean")
String Uid
String Showname
String Avtar
String State
Uid = jsonObject.getString("Uid")
Showname = jsonObject.getString("Showname")
Avtar = jsonObject.getString("Avtar")
State = jsonObject.getString("State")
带数组形式的:
服务器端返回的数据格式为:
复制代码代码如下:
{"calendar":
{"calendarlist":
[
{"calendar_id":"1705","title":"(\u4eb2\u5b50)ddssd","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288927800","endshowtime":"1288931400","allDay":false},
{"calendar_id":"1706","title":"(\u65c5\u884c)","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288933200","endshowtime":"1288936800","allDay":false}
]
}
}
分析代码如下:
复制代码代码如下:
// TODO 状态处理 500 200
int res = 0
res = httpClient.execute(httpPost).getStatusLine().getStatusCode()
if (res == 200) {
/*
* 当返回码为200时,做处理
* 得到服务器端返回json数据,并做处理
* */
HttpResponse httpResponse = httpClient.execute(httpPost)
StringBuilder builder = new StringBuilder()
BufferedReader bufferedReader2 = new BufferedReader(
new InputStreamReader(httpResponse.getEntity().getContent()))
String str2 = ""
for (String s = bufferedReader2.readLine()s != nulls = bufferedReader2
.readLine()) {
builder.append(s)
}
Log.i("cat", ">>>>>>" + builder.toString())
/**
* 这里需要分析服务器回传的json格式数据,
*/
JSONObject jsonObject = new JSONObject(builder.toString())
.getJSONObject("calendar")
JSONArray jsonArray = jsonObject.getJSONArray("calendarlist")
for(int i=0i<jsonArray.length()i++){
JSONObject jsonObject2 = (JSONObject)jsonArray.opt(i)
CalendarInfo calendarInfo = new CalendarInfo()
calendarInfo.setCalendar_id(jsonObject2.getString("calendar_id"))
calendarInfo.setTitle(jsonObject2.getString("title"))
calendarInfo.setCategory_name(jsonObject2.getString("category_name"))
calendarInfo.setShowtime(jsonObject2.getString("showtime"))
calendarInfo.setEndtime(jsonObject2.getString("endshowtime"))
calendarInfo.setAllDay(jsonObject2.getBoolean("allDay"))
calendarInfos.add(calendarInfo)
}
总结,普通形式的只需用JSONObject ,带数组形式的需要使用JSONArray 将其变成一个list。
