我要走了

卷曲错误：在URL中找到非法字符

这里我想使用

PHP

获取数据这里是文档：

我尝试过以下代码：

<?php

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "http://www.healthos.co
/api/v1/autocomplete/medicines/brands/CROCIN 125 MG SUSPENSION",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "GET",
  CURLOPT_HTTPHEADER => array(
    "authorization" => "12b570970d786ebf07c85496f5d2a7212fca81799c93379c43066206b6780885"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error:" . $err;
} else {
  echo $response;
}

请参阅文档：

从URL中删除新行

改变

CURLOPT_URL => "http://www.healthos.co
/api/v1/autocomplete/medicines/brands/CROCIN 125 MG SUSPENSION",

到

---

URL不正确，请按以下方式更改URL

www.healthos.co是无效的。更改为www.healthos.com

CURLOPT_URL => "http://www.healthos.com/api/v1/autocomplete/medicines/brands/CROCIN 125 MG SUSPENSION",

试试这个

• 我添加了

  urlencode（）

  ，以保持url的完整性
• 我从原始url中删除了新行

我的PHP HealthOS API示例 他们的API有示例代码，但不是针对PHP的，因此需要做一些工作才能转换为PHP：

<?php

// POST Request Access Token 

$fields = array(
    'grant_type' => "client_credentials",
    'client_id' => "faf4ad2651a7906fee8fab4c682ecc2721e16cc05771d8b32c807050ff621972",
    'client_secret' => "eb6731289c24359adcc76a98ed643de0b6f48526a4d56071d9c9cdb3656c3a9a",
    'scope' => "public read write"
);

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'http://www.healthos.co/api/v1/oauth/token.json',
  CURLOPT_RETURNTRANSFER => TRUE,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_POSTFIELDS => json_encode($fields),
  CURLOPT_HTTPHEADER => array(
    "content-type: application/json"
  )
));

$json_response = curl_exec($curl);

curl_close($curl);

$response = json_decode( $json_response, TRUE );
$access_token = $response['access_token'];


// GET Search Medicines

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "http://www.healthos.co/api/v1/autocomplete/medicines/brands/" . urlencode('CROCIN 125 MG SUSPENSION'),
  CURLOPT_RETURNTRANSFER => TRUE,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTPHEADER => array(
    "authorization: Bearer " . $access_token
  )
));

$json_response = curl_exec($curl);

curl_close($curl);

$response = json_decode( $json_response, TRUE );

echo '<pre>';
print_r( $response );
echo '</pre>';

我没有看到任何变化，原来的有什么问题？@EaB你在

www.healthos.co

之后有了新行请参考他们的文档：为什么你告诉了它无效的url<代码>www.healthos.co有效。并且您建议的URL无效。您的代码似乎正在工作，因为在仪表板中有对

crocin..

的请求。当我尝试时，我得到了一个空白屏幕，没有任何错误。为什么？是你自己管理的吗？没有其他代码？您可能需要在PHP中显示错误并启用错误报告来解决这个问题。什么版本的PHP？你有卷曲功能吗？另外，我进行了错误检查，因为我只是想让它工作。有可能API没有响应，或者因为来自世界各地的请求而禁止了您。我不知道。事实上，它对我来说仍然运行良好。我在一台Ubuntu 14.04机器上，使用PHP5.5.9。我会去我的PHP7机器那里检查一下。谢谢@Brain Gottier，谢谢你的努力，因为你的代码得到了一些理解。再次感谢你的欢迎。顺便说一句，我现在在一台使用PHP7的机器上，它在这里也工作得很好。
