About the pitfall of php calling. net web service,. netweb

From the past, the company had to connect to the other party as a web service. Because the other party uses the. net language, we use php. The manager originally asked us to use. net to write the web service server. I forgot all the. net files I learned at school...

As a result, I began to use php for programming for online search.

Modify php. ini; extension = php_soap.dll

First, write a simple server test method.

class Service {    public function HelloWorld() {        return "Hello";    }}

Save this method as a PHP file, and a web service file will be ready.

Because web service requires a wsdl file in xml format to parse the method. Therefore, we also need a wsdl file. net is more convenient to automatically generate, and php has to write it on our own. However, if there is already a wheel on the Internet, we just need to call it directly.

SoapDiscovery. class. php

Save the above Code as a PHP file as the manufacturing method of wsdl.

<? Phpinclude ("Service. php "); include (" SoapDiscovery. class. php "); $ disco = new SoapDiscovery ('service', 'service'); // The first parameter is the class name (the generated wsdl file is named by it ), that is, the Service class. The second parameter is the Service name (which can be written as needed ). $ Disco-> getWSDL ();

Finally, run the above Code to generate a wsdl file. However, the second parameter in new SoapDiscovery should be noted. This parameter is the service name of the service, which cannot be used when php is called, but if your web service is written. net, the name should be agreed with the other party. Because. net uses this name as the class name to call our method.

Now, the wsdl file is generated. At this time, we need to add a piece of code to the service method we first wrote.

<? Phpclass Service {public function HelloWorld () {return "Hello" ;}$ server = new SoapServer ('service. wsdl ', array ('soap _ version' => SOAP_1_2); $ server-> setClass ("Service "); // register all methods of the Service class $ server-> handle (); // process the request?>

As shown above. Here, the web service server is complete. Is the address of the Server File http://xxxxx.Service.php? Wsdl. You can send this address to someone else.

Next, create a client file. Here I don't need to write the method just now, with a weather forecast on the Internet web servcie http://www.webxml.com.cn/WebServices/WeatherWebService.asmx

<? Phpheader ("Content-Type: text/html; charset = UTF-8"); $ client = new SoapClient ('HTTP: // www.webxml.com.cn/WebServices/WeatherWebService.asmx? Wsdl '); var_dump ($ client->__ getFunctions (); // print out all the web servcie Methods $ aaa = $ client-> getsuppdatasdataset (); // call one of the methods without parameters var_dump ($ aaa); // The output return value print_r ($ aaa); // The output return value?>

Write a client file as above. In this case, I am calling. net method, stuck for a long time, and finally found that the parameter format of the other side is a problem, here special mention, pay attention to the parameter name in the other side of the wsdl file. If the "php [soap: Server] Server cannot process requests in normal mode. ---> When the root element is missing, pay attention to the parameter name in the target wsdl file. I used $ aaa = $ client->__ Call ("ApplyStateConfirm", array ($ str). This method is successful. Note that $ str is also an array, the key name is the parameter name specified in the target wsdl file.

Such a web service is successfully called.

Finally, if you find that some methods do not work during debugging, it is caused by the wsdl cache of php soap. Disable it in the php. ini file and restart nginx.

The solution is to modify soap. wsdl_cache_enabled = 1 (changed to 0) and soap. wsdl_cache_ttl = 86400 (changed to 0) in php. ini. Note that both the client and server must be modified.
