贝宝PayPal订单第2版：请求格式不正确，语法错误或违反架构

问题描述

我正在尝试使用PayPal API。这是Curl用法的参考：https://developer.paypal.com/docs/api/orders/v2/

在Google中搜索后，我发现了一个链接，该链接显示了类似的错误：但是，没有给出修复它的提示。 https://www.paypal-community.com/t5/REST-APIs/Request-is-not-well-formed-syntactically-incorrect-or-violates/td-p/2090480

我在PHP和Laravel中有以下代码

$client = new \GuzzleHttp\Client();
$response = $client->request('POST',$uri,[
        'headers' => [
            'Accept' => 'application/json','Accept-Language' => 'en_US','Content-Type' => 'application/json','Authorization' => "Bearer " . $this->token
        ],'form_params' => [
            "intent" => "CAPTURE","purchase_units" => [
                "amount" => [
                    "currency_code" => "USD","value" => "100.00"
                ]
            ]
        ]
    ]
);

运行代码时，出现以下错误

GuzzleHttp \ Exception \ ClientException客户端错误：POST https://api.sandBox.paypal.com/v2/checkout/orders导致400 Bad Request响应：{“ name”：“ INVALID_REQUEST”，“ message”：“请求为 格式不正确，语法错误或违反 模式。”，“ debug_id（已截断...）

更新1-修改了代码，如答案中所述，但仍然是相同的错误消息

$response = $client->request('POST',"purchase_units" => [
                [
                    "amount" => [
                        "currency_code" => "USD","value" => "100.00"
                    ]
                ]
            ]
        ]
    ]
);

解决方法

下面的代码对我有用。

$client = new \GuzzleHttp\Client();
$response = $client->request('POST',$uri,[
        'json' => [
            "intent" => "CAPTURE","purchase_units" => [
                [
                    "amount" => [
                        "currency_code" => "USD","value" => "100.00"
                    ]
                ]
            ]
        ],'headers' => [
            'Accept' => 'application/json','Accept-Language' => 'en_US','Content-Type' => 'application/json','Authorization' => "Bearer " . $this->token
        ]
    ]            
);

文件说：

purchase_units：数组（包含purchase_unit对象） 一组购买单位。每个购买单位在客户和商人之间建立合同。每个购买单位代表客户打算从商家购买的全部或部分订单。

您的purchase_units现在是purchase_unit，而不是purchase_unit数组，请尝试将form_params更改为

[
    "intent" => "CAPTURE","purchase_units" => [
       [ 
          "amount" => [
            "currency_code" => "USD","value" => "100.00"
          ]
       ]
    ]
]

,

    'form_params' => [

PayPal REST API不使用表单参数。

您需要发送一个“ json”数据对象。参见GuzzleHttp client documentation。
