Question

我有access_token，相关ID和数量。 请在CURL php中提供解决方案。 GIT网址https://github.com/paypal/PayPal-iOS-SDK/blob/master/docs/future_payments_server.md

curl 'https://api.paypal.com/v1/payments/payment' \
        -H "Content-Type: application/json" \
        -H "PayPal-Client-Metadata-Id: c2edbd6e97b14ff2b19ddb8eec9d264c" \
        -H "Authorization: Bearer WfXdnxmyJtdF4q59ofxuQuAAk6eEV-Njm6puht3Nk3w" \
        -d '{
               "intent":"authorize",
               "payer":{
                  "payment_method":"paypal"
               },
               "transactions":[
                  {
                     "amount":{
                        "currency":"USD",
                        "total":"1.88"
                     },
                     "description":"future of sauces"
                  }
               ]
            }'

$ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/payments/payment");
    curl_setopt($ch, CURLOPT_HEADER, "Content-Type: application/json");
    curl_setopt($ch, CURLINFO_HEADER_OUT, true);
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_HEADER, "PayPal-Client-Metadata-Id: 10aab1a2e941462096ca8aba539784f3");
    curl_setopt($ch, CURLOPT_HEADER, "Authorization: Bearer A103.Ekl88t1fnvoypD1F7HZDt3X-jzmxm6rxMxW6QtI79iIJdgDaDiIO8luWS-C1D-0z.h2YAz4LujULmTjQXcPjF8_ImbV0");
    curl_getinfo($ch, CURLINFO_HTTP_CODE);

    curl_setopt($ch, CURLOPT_POSTFIELDS, '{
           "intent":"authorize",
           "payer":{
              "payment_method":"paypal"
           },
           "transactions":[
              {
                 "amount":{
                    "currency":"USD",
                    "total":"1.88"
                 },
                 "description":"future of sauces"
              }
           ]
        }');

**using curl Php**

    $result1 = curl_exec($ch);
    $information = curl_getinfo($ch);
    curl_close($ch);
    print_r($result1);
    print_r($information);die;

返回curl信息1Array（[url] => https://api.sandbox.paypal.com/v1/payments/payment [content_type] => application / json [http_code] => 401 [header_size] => 520 [request_size] => 514 [文件时间] => -1 [ssl_verify_result] => 0 [重定向计数] => 0 [总时间] => 1.542536 [namelookup_time] => 0.341438 [connect_time] => 0.628821 [pretransfer_time] => 1.237494 [size_upload] = > 363 [size_download] => 0 [speed_download] => 0 [speed_upload] => 235 [download_content_length] => 0 [upload_content_length] => 363 [starttransfer_time] => 1.542478 [redirect_time] => 0 [redirect_url] => [ primary_ip] => 173.0.82.78 [certinfo] =>数组（）

Answer 1

至少，此代码对您要发送的HTTP标头有问题。

CURLOPT_HEADER设置为true ，将导致HTTP响应标头包含在cURL响应中。

要发送HTTP标头，您需要使用CURLOPT_HTTPHEADER并传递标头数组。

它看起来像这样：

$headers = array(
    'Content-Type: application/json',
    'PayPal-Client-Metadata-Id: 10aab1a2e941462096ca8aba539784f3',
    'Authorization: Bearer A103.Ekl88t1fnvoypD1F7HZDt3X-jzmxm6rxMxW6QtI79iIJdgDaDiIO8luWS-C1D-0z.h2YAz4LujULmTjQXcPjF8_ImbV0',
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

您还需要调用curl_setopt($ch, CURLOPT_POST, 1); 实际发送POST请求。
