我正在尝试将响应数组转换为JSON格式.我已经尝试了在SO和其他网站上发布的所有答案,如web1,web2添加header('Content-Type: application/json'),然后echo json_encode($data,JSON_PRETTY_PRINT); 我总是以文本格式获得输出.有人可以帮助我解决这个问题.

助手班级:

public static function renderJSON($data) {
    header('Content-Type: application/json');
    echo json_encode($data,JSON_PRETTY_PRINT);
}

我的控制器:

if ($model->login()) {
    $user =  User::findByUsernameOrEmail($request->post('username'));
    $userArray = ArrayHelper::toArray($user);
    Helpers::renderJSON($userArray);

我试着打印userArray它看起来像这样:

Array
(
    [name] => abc
    [lastname] => xyz
    [username] => test_test
)

Json输出:(html/text)

{
    "name": "abc",
    "lastname": "xyz",
    "username": "test_test"
}

我在文件夹中的文档很少,我想检查此文件夹中的所有文档是否已编入索引.为此,对于文件夹中的每个文档名称,我想为ES中索引的文档运行循环并进行比较.所以我想要检索所有文件.

有同样的问题的一些其他可能的重复就像检索一个(ElasticSearch)NEST查询所有记录,并在此处输入链接的描述,但他们没有帮助我的文档已经从那个时候改变了.(有什么关于扫描当前文档中)

我试过用client.search<T>().但根据文档,检索默认数量为10的结果.我想在不提及记录大小的情况下获取所有记录？(因为索引的大小会发生变化)

或者是否可以先获取索引的大小,然后将此数字作为输入发送到大小以获取所有文档并循环？

我正在尝试在我的笔记本电脑（PostGresSQL 9.6，PgAdmin3）中备份本地数据库，但我看到以下错误。

pg_dump：服务器版本：9.6.3；pg_dump 版本：9.5.5 pg_dump：由于服务器版本不匹配而中止

我已经尝试了一些关于 SO 的答案，比如在自制软件上更新 postgres，但它也抛出了一个错误。

错误：未安装 postgres

在查看postgres应用程序包的内容时，在versions文件夹中发现了2个文件夹，9.5和9.6。我尝试在两个版本的 bin 文件夹中运行 pg_dump ，我看到的只是这个错误：

有人可以帮我解决这个问题并备份我的数据库吗

我在使用时遇到unrecognized selector sent to instance错误NSKeyedArchiver.archivedData。

我试图将解析的 JSON 输出存储到自定义类对象中，并NSUserDefaults在成功登录时将其存储在其中。我想在其他控制器中使用这些详细信息来进行其他POST调用。但是，当将它们保存在我的中时，LoginController我收到此错误。有人可以帮助解决这个问题吗？

我的课：

class UserDetails : NSObject,NSCoding {


    var token:String?
    var agentId: Int?
    var userId:Int?


    //to directly get values from JSON output

    init?(user: [String: Any]) {

        guard let token = user["token"] as? String,
            let agentId = user["agent_id"] as? Int,
            let userId = user["user_id"] as? Int
        else{
            return nil
        }


                self.token = token;
                self.agentId = agentId;
                self.userId = userId;
        }

    init(pToken:String,pAgentId:Int,pUserId:Int)
    {
        token = pToken; …

我正在尝试以dd/MM/yyyy格式获取当月的开始和结束日期.我尝试使用扩展作为SO问题中的回答.但似乎这不是我想要的(格式不同,而且它给了我上个月的最后一个日期和当前月份,但是一个日期).有人能帮我吗.

扩展类:

extension Date {
    func startOfMonth() -> Date? {
        let comp: DateComponents = Calendar.current.dateComponents([.year, .month, .hour], from: Calendar.current.startOfDay(for: self))
        return Calendar.current.date(from: comp)!
    }

    func endOfMonth() -> Date? {
        var comp: DateComponents = Calendar.current.dateComponents([.month, .day, .hour], from: Calendar.current.startOfDay(for: self))
        comp.month = 1
        comp.day = -1
        return Calendar.current.date(byAdding: comp, to: self.startOfMonth()!)
    }
}

我的结构:

struct Constants{

    // keys required for making a Login call (POST Method)
    struct LoginKeys {
       .....
    }

    struct RankingKeys {

        static let DateFrom …

android studio 3.2 canary 13，gradle-4.6-all，classpath'com.android.tools.build:gradle:3.2.0-alpha13'ext.kotlin_version ='1.2.41'

当 使用谷歌Crashlytics集成编译我的项目https://github.com/1and1get2/trademeapidemo时出现以下错误

构建清理后，我将可以编译并运行没有问题。但是我认为这是一种解决方法，而不是解决方案

我正在尝试使用NEST复制下面的映射,并在将令牌字符映射到tokenizer时遇到问题.

我能够复制除令牌字符部分之外的所有内容.有人可以帮助这样做.下面是我的代码复制上面的映射.(令牌字符部分除外)

 var tChars = new List<string> { "letter", "digit", "punctuation", "symbol" };
