Question

var clients = [];

var tmp = [];

tmp["username"] = rows[0].username;
tmp["rank"] = rows[0].rank;
tmp["lastaction"] = "0";
tmp["connection"] = connection;
clients.push(tmp);

JSON.stringify(clients)

我初始化了一个数组（客户端）并将一个关联数组（tmp）推送到了clients数组。但如果我＆＃34; stringify＆＃34;客户，它将返回＆＃34; [[]]＆＃34;。

我错了什么？

提前谢谢。

Answer 1

像这样更新您的代码


    container = container.WithWeApi(config, assemblies, 
        throwIfUnresolved: type => type.Name.EndsWith("Controller"));

Asssociative数组不能直接支持你可以作为对象的javascript

Answer 2

您应该将tmp转换为对象文字而不是数组文字。

＆＃13;

var clients = [];

var tmp = {};

tmp["username"] = "foo";
tmp["rank"] = 1;
tmp["lastaction"] = "0";
tmp["connection"] = "bar";
clients.push(tmp);

console.log(JSON.stringify(clients))

＆＃13;

Answer 3

您需要将tmp初始化为对象：

＆＃13;

var clients = [];

var tmp = {};

tmp["username"] = 'username';
tmp["rank"] = 1
tmp["lastaction"] = 2
tmp["connection"] = 3
clients.push(tmp);

console.log(JSON.stringify(clients));

＆＃13;

JSON.stringify：JSON字符串将为空
