无法将 POST curl 从命令行转换为 php

Question

我在将 curl 命令转换为 php 时遇到问题。

这部分效果很好。

将条目添加到我的 Parse.com 数据库的 CURL 命令：

curl -X POST \
  -H "X-Parse-Application-Id: my_id" \
  -H "X-Parse-REST-API-Key: api_id" \
  -H "Content-Type: application/json" \
  -d "{\"SiteID\":\"foundID\",\"dataUsedString\":\"foundUsage\",\"usageDate\":\"foundDate\", \"monthString\":\"foundMonth\", \"dayString\":\"foundDay\",\"yearString\":\"foundYear\"}" \
  https://api.parse.com/1/classes/MyClass

已解决的答案：

我创建了这个 php 脚本来复制命令：

   <?php 
   $ch = curl_init('https://api.parse.com/1/classes/MyClass');

curl_setopt($ch,CURLOPT_HTTPHEADER,
    array('X-Parse-Application-Id:my_id',
'X-Parse-REST-API-Key:api_id',
'Content-Type: application/json'));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{\"SiteID\":\"foundID\",\"dataUsedString\":\"foundUsage\",\"usageDate\":\"foundDate\", \"monthString\":\"foundMonth\", \"dayString\":\"foundDay\",\"yearString\":\"foundYear\"}");

curl_exec($ch);
curl_close($ch);
?>

Answer 1

您遗漏了一些关键配置。 这些是设置 CURL 以使用 POST 发送请求，第二个是要发送的数据。 （原始数据作为字符串发送到 POSTFIELDS，如果您发送数组 - 它会自动附加标题“multipart/form-data”

$ch = curl_init('https://api.parse.com/1/classes/MyClass');

curl_setopt($ch,CURLOPT_HTTPHEADER,
  array(
    'X-Parse-Application-Id:my_id',
    'X-Parse-REST-API-Key:api_id',
    'Content-Type: application/json'
  )
);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{\"SiteID\":\"foundID\",\"dataUsedString\":\"foundUsage\",\"usageDate\":\"foundDate\", \"monthString\":\"foundMonth\", \"dayString\":\"foundDay\",\"yearString\":\"foundYear\"}");
curl_exec($ch);
curl_close($ch);

HTH:)

Answer 2

由于您正在执行 POST 请求，因此您需要告诉 Curl 也这样做：

$postData = '{"SiteID":"foundID","dataUsedString":"foundUsage","usageDate":"foundDate", "monthString":"foundMonth", "dayString":"foundDay","yearString":"foundYear"}';

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);

您可能还需要提供Content-Length 标头：

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
  'X-Parse-Application-Id: my_id',
  'X-Parse-REST-API-Key: api_id',
  'Content-Type: application/json',                                                           
  'Content-Length: '.strlen($postData))                                                                       
);
