Search for details of a book with Google Books API in PHP

Navigation
6

I'm using Google Books API to get the details of a book:

And to get the details of a book by searching by name, I'm using the following example provided by they , in this case the file simple-query.php within the examples folder.

What happens is that I can only do the search by author of books when calling this function: 

$results = $service->volumes->listVolumes('Catarina Coelho', $optParams);

How can I search by book name? I can not find any reference to doing the search by book name.

As I could not do it for the above mode, I found an example on the internet, but the search is done by the URL 

https://www.googleapis.com/books/v1/volumes?q=Memoria+historia+da+provincia+de+Santa+Catharina

If I use this solution through the URL, how can I get the result through the code and be saved inside a variable / array?

You can read the data by JSON and manipulate it as you see fit: 

<?php
$page = file_get_contents("https://www.googleapis.com/books/v1/volumes?q=Memoria+historia+da+provincia+de+Santa+Catharina");

$data = json_decode($page, true);

echo "Title = " . $data['items'][0]['volumeInfo']['title'];
echo "<br/>Authors = " . @implode(",", $data['items'][0]['volumeInfo']['authors']);    
?>

Here is an example to get the Title and Authors of the book.

In the Performing Search section, it is said that you can specify the book name ( or part of it) using the intitle parameter. For example: 

http https://www.googleapis.com/books/v1/volumes?q=intitle:Cem+Anos+de+Solidao

Try using this code: 

Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
    'Step 1:- google API url responsible for returning the book detail in JASON format
    Const GOOGLEAPIURL As String = "https://www.googleapis.com/books/v1/volumes?q=&#8221;"

    If txtISBN.Text <> String.Empty Then
        Dim requestURL As String

        'Step 2:- Reformed the URL to target particular ISBN number
        requestURL = GOOGLEAPIURL + txtISBN.Text() + "+isbn"

        'Step 3: created Http webrequest for URL
        Dim wr As HttpWebRequest = HttpWebRequest.Create(requestURL)
        'Step4 : get the response of web request in http web response object
        Dim resp As HttpWebResponse = wr.GetResponse()

        'Step 5: passes the response stream in stream reader
        Dim sreader As New StreamReader(resp.GetResponseStream())
        'Step 6: parsing the reader(which is in Jason format) using JASON.NET

        Dim rss = JObject.Parse(sreader.ReadToEnd())

        'Step 7: if object find the fetch the detail

        If rss Is Nothing = False AndAlso rss.Count > 0 Then
            lblBookName.Text = rss.Item("items")(0).Item("volumeInfo").Item("title").ToString()
            lblAuthor.Text = rss.Item("items")(0).Item("volumeInfo").Item("authors").ToString().Replace("[", "").Replace("]", "").ToString()
            lblPublisher.Text = rss.Item("items")(0).Item("volumeInfo").Item("publisher").ToString()
        Else
            lblMessage.Text = "Sorry ISBN Number not found, Please try different number."
        End If
    Else
        lblMessage.Text = "Please enter the ISBN number"
    End If
End Sub
