我正在尝试创建一个PHP脚本,它将一些JSON数据与压缩文件一起发送到API(InMobi),但我无法让它工作。我通常只是将标题设置为 application / json 并使用 curl_setopt($ ch,CURLOPT_POSTFIELDS,json_encode($ data)); 其中$ data是一个PHP数组但是怎么做我把文件附在那个上面?

请求应如下所示:

Content-Type: multipart/form-data; boundary=AYip2bnLbOw0R2vf8lDZ71pon3CDottfPlckt-E Content-Disposition: form-data; name="payload"
Content-Type: application/json; charset=US-ASCII
Content-Transfer-Encoding: 8bit

        "startDate": "2012-03-10",
        "endDate": "2012-05-31",
        "action": "create",
        "adGroups": [
            {
                "countryId": 94,
                "name": "First AdGroup",
                "bid": "1.89",
                "landingURL": "http://test.inmobi.com/sampleapp",
                "ctaDetails": {
                    "id": "1"
                },
                "action": "create",
                "ads": [
                    {
                        "type": "banner",
                        "name": "From Root",
                        "filePath": "/",
                        "altText": "3 img add",
                        "action": "create"
                    },
                    {
                        "type": "banner",
                        "name": "From ad1",
                        "filePath": "/ad1/",
                        "action": "create"
                    },
                    {
                        "type": "banner",
                        "name": "From ad2",
                        "filePath": "/ad2/",
                        "action": "create"
                    }
                ]
            }
        ]
    }
}

Content-Disposition: form-data; name="zipFile"; filename="banners.zip" Content-Type: application/octet-stream; charset=ISO-8859-1
Content-Transfer-Encoding: binary

<Contents of ZIP File>

在所有示例中,我看到他们将文件放在CURLOPT_POSTFIELDS中,但我不知道如何将其与json_encode结合使用,上述请求看起来就像文件是在请求的单独部分中发送的。

谢谢!

将数据拆分为两个字段:

$postdata = array(
    'json' => json_encode($whatever),
    'zipfile' => '@/path/to/yourfile.zip'
);

curl_setopt($curl, CURLOPT_POST_FIELDS, $postdata);

然后在接收端:

$json = json_decode($_POST['json');
$file = $_FILES['zipfile'];
