参考错误：未定义客户端

Question

我正在使用以下代码在jira中创建REST API调用： -

var loginArgs = {

data: {
    "username": "singhharwinder@seasiainfotech.com",
    "password": "Seasia@123"
},
headers: {
    "Content-Type": "application/json"
}

};

client.post（＆＃34; http://jira.atlassian.com/rest/auth/1/session＆＃34;，

loginArgs，function（data，response）{

if (response.statusCode == 200) {
    console.log('succesfully logged in, session:', data.session);

    var session = data.session;
    var searchArgs = {
        headers: {
            cookie: session.name + '=' + session.value,
            "Content-Type": "application/json"
        },
        data: {
            jql: "type=Bug AND status=Closed"
        }
    };

    client.post("http://jira.atlassian.com/rest/api/2/search", searchArgs, function (searchResult, response) {
        console.log('status code:', response.statusCode);
        console.log('search result:', searchResult);
    });
} else {
    throw "Login failed :(";
}

}）;

它给了我＆＃34;参考错误：客户端未定义＆＃34;。 请帮帮我。
