如何在发送变量时进行 HTTP GET 并使用 PHP 检索 XML 输出

发布于 2024-09-27 09:57:24 字数 1050 浏览 4 评论 0原文

我正在尝试使用此 API：www.cpsc.gov/cpscpub/prerel/api.html

文档：www.cpsc.gov/cpscpub/prerel/requirements.pdf

这是要发送的位置呼叫，其中还包括示例代码片段： http://www.cpsc.gov/cgibin/CPSCUpcWS/CPSCUpcSvc.asmx

getRecallByWord 函数应返回 XML 数据。

这是用于获取数据的预制 URL（注意，根据文档必须使用 https）： www.cpsc.gov/cgibin/CPSCUpcWS/CPSCUpcSvc.asmx/getRecallByWord?message1=3M&password=password&userId=userId

在文档中有一条注释，不需要特定的用户名或密码（任何都可以）

我已经尝试了 fopen、file_get_contents 和 http_get （尽管最后一个由于未安装扩展而不起作用）。

$result = fopen("https://www.cpsc.gov/cgibin/CPSCUpcWS/CPSCUpcSvc.asmx/getRecallByWord?message1=3M&password=password&userID=userId",r);  
print $result;  
print "done";    
$response = file_get_contents("https://www.cpsc.gov/cgibin/CPSCUpcWS/CPSCUpcSvc.asmx/getRecallByWord?message1=3M&password=password&userID=userId");  
print $response;  
print "done";

输出：
资源 id #3done 已完成

allowed_url_fopen 已开启

I'm trying to use this API: www.cpsc.gov/cpscpub/prerel/api.html

Documentation: www.cpsc.gov/cpscpub/prerel/requirements.pdf

Here is the location calls are to be sent, which also includes sample code snippets: http://www.cpsc.gov/cgibin/CPSCUpcWS/CPSCUpcSvc.asmx

The getRecallByWord function should return XML data.

Here's a preformed URL for getting the data (note, have to use https according to doc):
www.cpsc.gov/cgibin/CPSCUpcWS/CPSCUpcSvc.asmx/getRecallByWord?message1=3M&password=password&userId=userId

In the documentation there is a note that no specific username or password is required (anything will work)

I've tried fopen, file_get_contents, and http_get (although the last one didn't work since extension isn't installed).

$result = fopen("https://www.cpsc.gov/cgibin/CPSCUpcWS/CPSCUpcSvc.asmx/getRecallByWord?message1=3M&password=password&userID=userId",r);  
print $result;  
print "done";    
$response = file_get_contents("https://www.cpsc.gov/cgibin/CPSCUpcWS/CPSCUpcSvc.asmx/getRecallByWord?message1=3M&password=password&userID=userId");  
print $response;  
print "done";

Output:
Resource id #3done done

allow_url_fopen is On

如果 xml 返回，您的浏览器将“隐藏”它 - 查看页面源代码，您就会看到它。

这对我来说适用于 file_get_contents （不要忘记在 URL 之前添加协议）。 PHP 手册指定您需要启用 fopen_wrappers 才能使其正常工作。执行 phpinfo 并查找 allow_url_fopen。

另一种选择是使用 cURL 库（我推荐）。

我尝试过，与我的代码配合得很好：

<?php 
    $content = file_get_contents('http://www.cpsc.gov/cgibin/CPSCUpcWS/CPSCUpcSvc.asmx/getRecallByWord?message1=3M&password=password&userId=userId');
    header('Content-Type: text/xml; charset=utf-8');
    print $content;
    exit();

<?xml version="1.0" encoding="utf-8"?>
<message outcome="success" transactionID="6B3E350A-C90B-4726-A237-F76FC51C4237">
  <results>
    <result UPC="" recallNo="73017" recallURL="http://www.cpsc.gov/cpscpub/prerel/prhtml73/73017.html" recDate="" y2k="73017" manufacturer="3M" type="" prname="Shipping Mate Palletizing Adhesive aerosol spray adhesives" hazard="" country_mfg="" />
    <result UPC="" recallNo="96097" recallURL="http://www.cpsc.gov/cpscpub/prerel/prhtml96/96097.html" recDate="1996-04-21" y2k="96097" manufacturer="3M" type="Projectors" prname="3M overhead projectors" hazard="Electrocution/Electric Shock" country_mfg="" />
    <result UPC="" recallNo="73014" recallURL="http://www.cpsc.gov/cpscpub/prerel/prhtml73/73014.html" recDate="" y2k="73014" manufacturer="3M" type="Arts & Crafts" prname="Foil Art Spray Adhesive aerosol spray adhesives" hazard="" country_mfg="" />
  </results>
</message>

如果启用了allow_url_fopen，也许检查您的PHP配置？

I tried it, works just fine with my code:

<?php 
    $content = file_get_contents('http://www.cpsc.gov/cgibin/CPSCUpcWS/CPSCUpcSvc.asmx/getRecallByWord?message1=3M&password=password&userId=userId');
    header('Content-Type: text/xml; charset=utf-8');
    print $content;
    exit();

returns:

<?xml version="1.0" encoding="utf-8"?>
<message outcome="success" transactionID="6B3E350A-C90B-4726-A237-F76FC51C4237">
  <results>
    <result UPC="" recallNo="73017" recallURL="http://www.cpsc.gov/cpscpub/prerel/prhtml73/73017.html" recDate="" y2k="73017" manufacturer="3M" type="" prname="Shipping Mate Palletizing Adhesive aerosol spray adhesives" hazard="" country_mfg="" />
    <result UPC="" recallNo="96097" recallURL="http://www.cpsc.gov/cpscpub/prerel/prhtml96/96097.html" recDate="1996-04-21" y2k="96097" manufacturer="3M" type="Projectors" prname="3M overhead projectors" hazard="Electrocution/Electric Shock" country_mfg="" />
    <result UPC="" recallNo="73014" recallURL="http://www.cpsc.gov/cpscpub/prerel/prhtml73/73014.html" recDate="" y2k="73014" manufacturer="3M" type="Arts & Crafts" prname="Foil Art Spray Adhesive aerosol spray adhesives" hazard="" country_mfg="" />
  </results>
</message>

Maybe check your PHP Configuration if allow_url_fopen is enabled?
