将php数组转换为json（coinbase）

Question

我正在寻找一种解决方案，用于从类属性中的PHP数组中读取数据。

请求：

$accounts = $client->getAccounts();

这是结果数组：

Coinbase\Wallet\Resource\ResourceCollection Object
(
    [previousUri:Coinbase\Wallet\Resource\ResourceCollection:private] => 
    [nextUri:Coinbase\Wallet\Resource\ResourceCollection:private] => 
    [resources:Coinbase\Wallet\Resource\ResourceCollection:private] => Array
        (
            [0] => Coinbase\Wallet\Resource\Account Object
                (
                    [name:Coinbase\Wallet\Resource\Account:private] => BTC Wallet
                    [primary:Coinbase\Wallet\Resource\Account:private] => 1
                    [type:Coinbase\Wallet\Resource\Account:private] => wallet
                    [currency:Coinbase\Wallet\Resource\Account:private] => BTC
                    [balance:Coinbase\Wallet\Resource\Account:private] => Coinbase\Wallet\Value\Money Object
                        (
                            [amount:Coinbase\Wallet\Value\Money:private] => 0.00001
                            [currency:Coinbase\Wallet\Value\Money:private] => BTC
                        )

                    [nativeBalance:Coinbase\Wallet\Resource\Account:private] => Coinbase\Wallet\Value\Money Object
                        (
                            [amount:Coinbase\Wallet\Value\Money:private] => 0.01
                            [currency:Coinbase\Wallet\Value\Money:private] => CHF
                        )

                    [createdAt:Coinbase\Wallet\Resource\Account:private] => DateTime Object
                        (
                            [date] => 2017-11-04 01:35:13.000000
                            [timezone_type] => 2
                            [timezone] => Z
                        )

                    [updatedAt:Coinbase\Wallet\Resource\Account:private] => DateTime Object
                        (
                            [date] => 2017-11-04 14:24:11.000000
                            [timezone_type] => 2
                            [timezone] => Z
                        )

                    [id:Coinbase\Wallet\Resource\Resource:private] => XXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX
                    [resource:Coinbase\Wallet\Resource\Resource:private] => account
                    [resourcePath:Coinbase\Wallet\Resource\Resource:private] => /v2/accounts/XXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX
                    [rawData:Coinbase\Wallet\Resource\Resource:private] => Array
                        (
                            [id] => XXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX
                            [name] => BTC Wallet
                            [primary] => 1
                            [type] => wallet
                            [currency] => BTC
                            [balance] => Array
                                (
                                    [amount] => 0.001
                                    [currency] => BTC
                                )

                            [created_at] => 2017-11-04T01:35:13Z
                            [updated_at] => 2017-11-04T14:24:11Z
                            [resource] => account
                            [resource_path] => /v2/accounts/XXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX
                            [native_balance] => Array
                                (
                                    [amount] => 0.01
                                    [currency] => CHF
                                )

                        )

                )

        )

)

现在，我想读取$accounts['rawData']['id']，其值为XXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX 我已经尝试将这些响应转换为这样的JSON数组：

$aaax = json_encode($accounts);
$bbbx = json_decode($aaax, true);

但是它不起作用。上

print_r($bbbx)

我只收到

Array
(

您知道我如何从输出数组读取/获取数据吗？

Answer 1

问题是您班级的所有属性都具有private visibility。这意味着您在课程之外的代码无法读取或修改这些属性。

您需要修改类以使代码可访问这些属性，或者至少在运行json_encode()时告诉PHP包括私有属性。假设您不能这样做，因为这是一个库，而不是您编写的代码，则需要将该类包装在实现JsonSerializable的包装器类中。

感谢Ed Cottrell的帮助以及技术术语的更正。那是我学习的最好方法。我试图用JsonSerializable :: jsonSerialize解决这个问题。没办法（对我来说...）

现在，我找到了另一种访问数据的解决方案。我使用php包装器： https://github.com/coinbase/coinbase-php

有一种方法可以访问RawData

$data = $client->decodeLastResponse();

就我而言，以下代码：

$accounts = $client->getAccounts();
$dataX = $client->decodeLastResponse();
print_r($dataX);

所以我得到以下响应：

Array
(
    [pagination] => Array
        (
            [ending_before] => 
            [starting_after] => 
            [limit] => 25
            [order] => desc
            [previous_uri] => 
            [next_uri] => 
        )

    [data] => Array
        (
            [0] => Array
                (
                    [id] => XXXXXXXXXXXXXXXXXXX
                    [name] => BTC Wallet
                    [primary] => 1
                    [type] => wallet
                    [currency] => BTC
                    [balance] => Array
                        (
                            [amount] => 0.001
                            [currency] => BTC
                        )

                    [created_at] => 2017-11-04T01:35:13Z
                    [updated_at] => 2017-11-04T14:24:11Z
                    [resource] => account
                    [resource_path] => /v2/accounts/XXXXXXXXXXXXXXXXXXX
                    [native_balance] => Array
                        (
                            [amount] => 0.001
                            [currency] => CHF
                        )

                )

        )

)

因此完全可以访问 再次感谢您（让我敞开心opening .. :-））我用Google搜索“ coinbase jsonserialize”找到了这个解决方案...这是您的输入。
