Question

我正在尝试对我的同事开发的演示网络服务进行身份验证。如果我尝试从Chrome中的Advanced rest客户端插件调用，则允许跨源资源共享并且工作正常。但是当我尝试使用代码访问时，我得到500服务器错误

.ajax({ 
        type : "POST",  
        dataType: 'json',
        url: 'CANTPOSTTHISURL/rest/session',
        contentType: "application/json; charset=utf-8",      
        data: JSON.stringify({"username": "admin", "password": "admin" }),
        success: function(response)
        {
            console.log(response); 
        },
        error: function (data, status) {
            console.log( 'Sample of error data:', status );
            console.log("readyState: "+data.readyState+"\nstatus: "+data.status+"\nresponseText: "+data.responseText);
        },
        complete: function(xhr, status ) {
            console.log( 'COMPLETE');
        }   
  });

我得到的错误是：

我认为这是我发送的数据，但我也尝试过＆＃39; {＆＃34;用户名＆＃34;：＆＃34;管理员＆＃34;，＆＃34;密码＆＃34 ;：＆＃34; admin＆＃34; }＆＃39;或{＆＃34;用户名＆＃34;：＆＃34;管理员＆＃34;，＆＃34;密码＆＃34;：＆＃34;管理员＆＃34;但没有任何改变。一个重要的评论：我只能执行POST或OPTION请求，所以没有jsonp 谢谢

我认为你不需要使用stringify方法。

我正在使用以下格式，它适用于我：

url : "http://localhost:9200/" + eleName + "/_suggest",
type : "POST",
dataType : "json",
ContentType: "application/json; charset=utf-8",
data:"{\"result\":{\"text\":\"" + request.term + "\",\"completion\":{\"size\" :10,\"field\":\"name_suggest\"}}}",

尝试使用JSON格式的String。
