Overview ======== This README describes the client Google Web APIs distribution. This package is all you need to use Google's SOAP-based API. Inside you'll find a WSDL file which formally describes the API. It can be used with any language with web services support to call Google. We also provide a custom Java library that provides a convenience wrapper for Java programmers. Finally, we have example .NET programs in Visual Basic and in C# that call the Google Web APIs. For more details, see below. The Google Web APIs service is in beta release. All interfaces are subject to change as we refine and extend our APIs. Please see the terms of use (in the file "LICENSE.txt") for more information. For questions, comments, etc, please mail Google at You can also discuss Google Web APIs using the Google Group google.public.web-apis available at http://groups.google.com/groups?hl=en&group=google.public.web-apis Registration and key -------------------- In order to use Google Web APIs you first must register with Google to receive an authentication key. You can do this online at http://www.google.com/apis/. Your key will have a limit on the number of requests a day that you can make. The default limit is 1000 queries per day. If you have problems with your key or getting the correct the daily quota of queries, plase contact . How to use the Java API ----------------------- To quickly try the API, run java -cp googleapi.jar com.google.soap.search.GoogleAPIDemo search Foo Where is your registration key and Foo is the item you wish to search for. GoogleAPIDemo is a simple demonstration of how to use the Java API included in googleapi.jar. For usage, run it with no arguments: java -cp googleapi.jar com.google.soap.search.GoogleAPIDemo GoogleAPIDemo is only a demonstration; Java programmers should look at the source for GoogleAPIDemo and the included Javadoc for the GoogleSearch class to learn more about how to use our Java library. The library has our SOAP endpoint address built in. You may want to override this endpoint, for instance to point it at a debugging proxy. You can do this either by calling the appropriate method in GoogleSearch or by setting the Java property "google.soapEndpointURL". The default URL is http://api.google.com/search/beta2 How to use the .NET Examples ---------------------------- We have provided example programs that call the Google Web APIs service from .NET. In the dotnet directory you will find files for these examples, including CSharp Example.exe and VB Example.exe Pre-built executables, requires .NET Framework installed on your machine CSharp\Form1.cs Simple GUI program in C# that calls the API CSharp\Google Web APIs Demo.csproj Project file for the API demo; open in Visual Studio .NET Visual Basic\Google Demo Form.vb Simple GUI program in VB that calls the API Visual Basic\VB Google Web APIs.vbproj Project file for the API demo; open in Visual Studio .NET To browse the code, simply look at the end of the Form code for the methods at the end that handle clicks on the buttons. The Visual Basic and C# examples are functionally identical. How to use the WSDL File ------------------------ The WSDL file provides a standard description of Google's search services. The file is included with this kit, and is also at http://api.google.com/GoogleSearch.wsdl Many programming languages now understand WSDL and can use this file to automatically invoke Google's API. For example, the WSDL can be imported into .NET, converted into Java code using Apache Axis WSDL2Java, or used directly by Perl SOAP::Lite. The WSDL file has been tested with SOAP::Lite 0.52, the .NET Framework, (via "Add Web Reference" or wsdl.exe version 1.0.3705.0), and Apache Axis Beta 1. Below is a simple Perl script to use the WSDL file to do a query: use SOAP::Lite; my $key='000000000000000000000000'; my $query="foo"; my $googleSearch = SOAP::Lite -> service("file:GoogleSearch.wsdl"); my $result = $googleSearch -> doGoogleSearch($key, $query, 0, 10, "false", "", "false", "", "latin1", "latin1"); print "About $result->{'estimatedTotalResultsCount'} results.\n"; Contents of this package: ========================= googleapi.jar Java library for accessing the Google Web APIs service.

This product includes software developed by the Apache Software Foundation (http://www.apache.org/). Release notes ============= 2002-08-30: Bug fix release for beta2. Released a new example client for Visual Basic .NET. Updated the C# .NET example client Colors fixed, exception handling, GoogleSearch proxy now generated via "Add Web Reference" rather than "wsdl.exe". Updated WSDL file to correct a bug. Visual Studio .NET's "Add Web Reference" feature now supported. Added support to Java client for HTTP proxies. GoogleSearch has new methods for setting proxy host, port, and username and password. Alternately, if the Java system properties "http.proxyHost" and "http.proxyPort" are set, those will be used. Implemented new mechanism for internationalization and non-ASCII queries. Server now correctly handles UTF-8 input and output. UTF-8 is now the only supported encoding. The APIs server used to handle data in ISO-Latin-1 regardless of what encoding was requested. Now it reads and sends data in UTF-8. Clients that expect ISO-Latin-1 will need to change to handle UTF-8 data instead. This affects clients issuing queries in many Western European languages; non-ASCII characters such as Eszett (U+00df) or e-grave (U+00e8) are now encoded as two bytes of UTF-8, not one byte of ISO-Latin-1. ASCII results are unaffected. Query parameters and are now ignored; UTF-8 everywhere. Deprecated Java client methods setInputEncoding() and setOutputEncoding(). Updated the APIs_Reference.html documentation. The section on Input and Output Encodings now notes that UTF-8 is the only supported encoding, and that the and parameters are ignored. Queries in CJK languages (Chinese, Japanese, and Korean) still do not work completely correctly. A future release will address these problems. 2002-04-11: Public release of beta2 of the Google Web APIs service.
