使用Rackspace API卷曲PHP錯誤

Question

我正在嘗試使用Rackspace的“ Cloud Identity” API生成令牌（ https://developer.rackspace.com/docs/cloud-identity/v2/developer-guide/#generate-an-authentication-token ）

這是我需要的要求：

$ curl https://identity.api.rackspacecloud.com/v2.0/tokens  \
-X POST \
-d '{"auth":{"RAX-KSKEY:apiKeyCredentials":{"username":"yourUserName","apiKey":"yourPassword"}}}' \
-H "Content-type: application/json" | python -m json.tool

這就是我試圖做到的：

<?php
$url = 'https://identity.api.rackspacecloud.com/v2.0/tokens';
$apiKey = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
$data = "'{\"auth\":{\"RAX-KSKEY:apiKeyCredentials\":{\"username\":\"XXXXXXXX\",\"apiKey\":\"$apiKey\"}}}'";
$headers = array();
$headers[0] = '"Content-Type: application/json" | python -m json.tool';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 20);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_NONE);
$response = curl_exec($ch);
$info = curl_getinfo($ch, CURLINFO_HTTP_CODE);
echo($info);
?>

我得到了：415 {“ unsupportedMediaType”：{“ code”：415}}

當我更改標題時

$headers[0] = '"Content-Type: application/json" | python -m json.tool'; 

至

$headers[0] = 'Content-Type: application/json | python -m json.tool';

我明白了

最后，當我將標題更改為這一標題時：

$headers[0] = 'Content-Type: application/json';

我收到以下錯誤代碼：400 {“ badRequest”：{“ code”：400，“ message”：“無效的json請求正文”}}

我做對了嗎？ 提前致謝。

有什么理由不使用PHP SDK ？ 這樣可以很容易地做到這一點。

您需要將PHP更改為：

<?php
$url = 'https://identity.api.rackspacecloud.com/v2.0/tokens';
$username = 'foo';
$apiKey = 'bar';

$data = <<<EOT
{"auth": {"RAX-KSKEY:apiKeyCredentials":{"username":"$username","apiKey":"$apiKey"}}}
EOT;

$headers = array('Content-Type: application/json');

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 20);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_NONE);

$response = curl_exec($ch);

echo curl_getinfo($ch, CURLINFO_HTTP_CODE);
