Ajax设置Rquest Body和Header为application/json格式

我一开始以为的Ajax请求设置RequestBody为json格式就完了，但是没有想到，当我在使用有人云API接口的时候，查看文档，让我懵逼了。tm的RquestHeader怎么设置为application/json。

后来度娘了以后大部分都是如何设置RequestBody为application/json格式。RequestHeader的说明很少。所以在此记录一下

Ajax设置Request Body为JSON格式

1.  
   var account = {
2.  
   "account": "15901085978",
3.  
   "password": "23b9f889d2826d224d16eb9399652695"
4.  
   };
5.  
   account = JSON.stringify(account);
6.  
    
7.  
   $.ajax({
8.  
   type: "post",
9.  
   url: "http://localhost/login",
10.  
    contentType: "application/json; charset=utf-8",
11.  
    data: account,
12.  
    dataType: "json",
13.  
    success: function(data) {
14.  
    console.log(data);
15.  
    },
16.  
    error: function(XMLHttpRequest, textStatus, errorThrown) {
17.  
    console.log("request.status:" XMLHttpRequest.status " request.readyState:" XMLHttpRequest.readyState " textStatus:" textStatus);
18.  
    }
19.  
    });

Ajax设置Request Header为JSON格式

1.  
   var uid2 = {
2.  
   "uid": "104294"
3.  
   };
4.  
   uid2 = JSON.stringify(uid2);
5.  
   var token2="111";
6.  
    
7.  
   $.ajax({
8.  
   type: "post",
9.  
   url: "https://openapi.mp.usr.cn/usrCloud/vn/dev/getDevsForVn",
10.  
    contentType: "application/json; charset=utf-8",
11.  
    data: uid2,
12.  
    dataType: "json",
13.  
    headers: {
14.  
    "Content-Type": "application/json",
15.  
    "token": token2
16.  
    },
17.  
    success: function(data) {
18.  
    console.log(data);
19.  
    },
20.  
    error: function(XMLHttpRequest, textStatus, errorThrown) {
