My .wsdl file is downloading but not opening, Parsing WSDL error

Question

I'm trying to read a wsdl file, I get an error:

Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://localhost:8081/soap/news.wsdl' : failed to load external entity "http://localhost:8081/soap/news.wsdl" in /var/www/app/soap/soap-client.php:22 Stack trace: #0 /var/www/app/soap/soap-client.php(22): SoapClient->SoapClient('http://localhos...', Array) #1 {main} thrown in /var/www/app/soap/soap-client.php on line 22

Here is my code in server-client.php:

$url = "http://localhost:8081/soap/news.wsdl";
$client = new SoapClient($url);

After reading the forums, tried adding the extension "openssl", but the error remains. When I try to open http://localhost:8081/soap/news.wsdl , the file is not opened, but downloaded automatically. I tried spelling in nginx cfg:

location ~ \.wsdl$ {
        root /var/www/app;
        default_type application/xml;
        }

But that didn't help either.

I think the problem is in the nginx config. My config:

server {
    listen 80;
    index index.php;
    server_name localhost;
    error_log  /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
    root /var/www/app;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
        gzip_static on;
    }

    location ~ \.php$ {

        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;

        fastcgi_buffer_size 128k;
        fastcgi_buffers 4 256k;
        fastcgi_busy_buffers_size 256k;

        fastcgi_pass php-fpm:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $realpath_root;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }

        location ~ \.wsdl$ {
        root /var/www/app;
        default_type application/xml;
    } 
}

My WSDL file "news.wsdl" :

By the way, I tried opening another person's .wsdl file. He was fine. Please help me with this problem, I've already broken my head :(

Answer 1

I had the same problem and i took few days to figure out how to fix it.

My code works fine in DEV but not in PROD.

The problem was because of libxml Version:

• In dev: libxml Version 2.7.6
• In prod: libxml Version 2.9.1

( You can check your version echoing: phpinfo(); )

To resolve the problem try to:

Add this: libxml_disable_entity_loader(false); before loading your external xml

This function disable/enable the ability to load external entities. And it seems to be disabled by default since libxml 2.9.0

https://www.php.net/manual/en/function.libxml-disable-entity-loader.php

Good luck!
