本文實例講述了PHP使用SOAP調用API操作。分享給大家供大家參考，具體如下：

/*圖片轉換為 base64格式編碼*/
function base64EncodeImage($image_file)
{
  $base64_image = '';
  $image_info = getimagesize($image_file);
  $image_data = fread(fopen($image_file, 'r'), filesize($image_file));
  //$base64_image = 'data:' . $image_info['mime'] . ';base64,' . chunk_split(base64_encode($image_data));
  $base64_image = chunk_split(base64_encode($image_data));
  return $base64_image;
}
$strPhotoFront_base64 = base64EncodeImage("static/img/a.png");
$strPhotoRear_base64 = base64EncodeImage("static/img/b.png");
$paras["strPhotoFront"] = $strPhotoFront_base64;
$paras["strPhotoRear"] = $strPhotoRear_base64;
$paras["strSecretKey"] = "";
$wsdl = "";
$client = new SoapClient($wsdl);
$soapParas = array($paras);
$outString = $client->__soapCall("UploadPhotoId", $soapParas);
$obj = simplexml_load_string($outString->UploadPhotoIdResult->any);
echo($obj->ExtraInfo);
echo "<br/>";
echo($obj->ExtraCode);
echo "<br/>";
echo($obj->Code);
echo "<br/>";
echo($obj->Message);

注：出現提示：Fatal error: Class 'SoapClient' not found的情況，可參考《PHP Class SoapClient not found解決方法》

附：SOAP-ERROR: Parsing WSDL:Couldn't load from “xxxxxxx” 解決方案

用php的soapclient連接第三方的webservice，是https的，連接報錯SOAP-ERROR: Parsing WSDL:Couldn't load from “xxxxxxx”

首先排查 php的soap擴展是否安裝

openssl擴展

服務器本身安裝openssl

排除第三方對本服務器的IP限制

最后懷疑是https需要ssl驗證，而本機沒有pem文件

可以通過如下設置，忽略ssl驗證

verify_peer：指定是否驗證ssl，默認為true

將verify_peer設為false

另外，允許引用外部xml實體

加libxml_disable_entity_loader(false);語句

libxml_disable_entity_loader(false);
$opts = array(
  'ssl'  => array(
      'verify_peer'     => false
    ),
  'https' => array(
      'curl_verify_ssl_peer' => false,
      'curl_verify_ssl_host' => false
   )
);
$streamContext = stream_context_create($opts);
$client = new SoapClient("https://urlToSoapWs",
 array(
   'stream_context'  => $streamContext
 ));

禁止引用外部xml實體

libxml_disable_entity_loader(true);

nginx 報錯 upstream timed out (110: Connection timed out)解決方案

nginx每隔幾個小時就會報下面的錯誤：

2013/05/18 21:21:36 [error] 11618#0: *324911 upstream timed out (110: Connection timed out) while reading response header from upstream,
client: 42.62.37.56, server: localhost, request: “GET /code-snippet/2747/HTML5-Canvas-usage HTTP/1.0”,
upstream: “fastcgi://127.0.0.1:9002”, host: “outofmemory.cn”, referrer: “http://outofmemory.cn/code-snippet/tagged/canvas“

報這個錯誤之后，整個服務器就不響應了，但是nginx后面的webpy程序沒有任何錯誤，后端的數據庫也很正常，從網上查了很多資料，都是說要修改proxy_read_timeout,proxy_send_timeout和proxy_buffer幾個相關設置的值。

如下配置，要放在server配置節之內

large_client_header_buffers 4 16k;
client_max_body_size 30m;
client_body_buffer_size 128k;
proxy_connect_timeout 300;
proxy_read_timeout 300;
proxy_send_timeout 300;
proxy_buffer_size 64k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
fastcgi_connect_timeout 300;
fastcgi_read_timeout 300;
fastcgi_send_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 32k;
fastcgi_busy_buffers_size 64k;
fastcgi_temp_file_write_size 64k;
