Shulou(Shulou.com)06/03 Report--

After I had written half of the article before, after saving the draft, I finally found that it was gone, so I had to write it all over again. This time, I would not be so verbose, mainly sharing the steps of the test.

There are three ways for LoadRunner to test webservice: 1, through the web_service_call function, that is, to import the wsdl file or URL; 2, through the soap_request function, by importing the xml file to achieve; 3, through the http protocol to handwrite scripts.

The first can be accessed: http://gungun.blog.51cto.com/9585287/1591100

Today's focus is on the second, which imports the xml file through Import SOAP to implement the call to the webservice interface.

Let's take the well-known weather forecast as an example:

URL: http://webservice.webxml.com.cn/webservices/weatherwebservice.asmx for Weather Forecast

Call the getWeatherbyCityName method.

Open the http://webservice.webxml.com.cn/webservices/weatherwebservice.asmx?op=getWeatherbyCityName page, as shown in the following figure:

Save the portion of the red box below to the xml file and import the XML file you just had, as shown in the following figure:

The following code is automatically generated after import:

Soap_request ("StepName=SOAP Request"

"URL= http://webservice.webxml.com.cn/webservices/weatherwebservice.asmx",

"SOAPEnvelope="

"

"

"

"string" / / fill in the name of the city here

"

"

"

"SOAPAction=getWeatherbyCityName"

"ResponseParam=response"

"Snapshot=t1418827945.inf"

LAST)

Then add the header information before the code you just generated. The content that needs to be added is shown in the first figure, where "Content-Length" does not need to be added.

The additional code to be added in this example is as follows:

Web_add_header ("POST"

"/ WebServices/WeatherWebService.asmx HTTP/1.1")

Web_add_header ("Host"

"webservice.webxml.com.cn")

Web_add_header ("Content-Type"

"application/soap+xml; charset=utf-8") / / the note here is different from the screenshot.

Web_add_header ("SOAPAction"

"\" http://WebXml.com.cn/getWeatherbyCityName\"");

This is done simply by testing Webservice through the soap_request function.

After fetching the XML data returned by WebService, you can use XPath to validate the data. LR provides several functions to handle XML:

Lr_xml_get_values () / / Retrieves values of XML elements found by a query

Lr_xml_set_values () / / Sets the values of XML elements found by a query

Lr_xml_extract () / / Extracts XML string fragments from an XML string

Lr_xml_delete () / / Deletes fragments from an XML string

Lr_xml_replace () / / Replaces fragments of an XML string

Lr_xml_insert () / / Inserts a new XML fragment into an XML string

Lr_xml_find () / / Verifies that XML values are returned by a query

Lr_xml_transform () / / Applies Extensible Stylesheet Language (XSL) Transformation to XML data
