jquery之ajax篇
一.jquery ajax设置header的两种方式
1.设置headers参数:
headers: {
// "Authorization":"Basic "+ auth,
'Content-Type': 'application/json'
},
2.设置在beforeSend方法中
beforeSend: function (xhr) {
xhr.setRequestHeader("tokenId", getTokenId());
},
相应也需要后台配置headers,后台以node为例,配置如下:
app.all('*', function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Content-Type,Content-Length, Authorization, Accept,X-Requested-With, tokenId");
res.header("Access-Control-Allow-Methods","PUT,POST,GET,DELETE,OPTIONS");
res.header('Access-Control-Allow-Credentials', 'true');
res.header("X-Powered-By",' 3.2.1')
next();
});
二.jquery ajax设置data参数
var srcData = {
username: localStorage.username,
password: localStorage.password,
tokenId: localStorage.tokenId
}
$.ajax({
url: '/users/logout',
type: 'delete',
data: srcData,
## 设置传入data的格式为json
dataType: 'json',
