我试图从谷歌API中获取一些信息，但遇到了一些麻烦。我的代码：

$body = array(
    \'intitle\' => \'Test\', //Returns results where the text following this keyword is found in the title.
    \'inauthor\' => \'\',  //Returns results where the text following this keyword is found in the author.
    \'inpublisher\' => \'\',  //Returns results where the text following this keyword is found in the publisher.
    \'key\' => \'\', //API key
    \'subject\' => \'\', //Returns results where the text following this keyword is listed in the category list of the volume.
    \'isbn\' => \'\',  //Returns results where the text following this keyword is the ISBN number.
    \'lccn\' => \'\',  //Returns results where the text following this keyword is the Library of Congress Control Number.
    \'oclc\' => \'\'  //Returns results where the text following this keyword is the Online Computer Library Center number.
);

$args = array(
    \'body\' => $body,
    \'timeout\' => \'5\',
    \'redirection\' => \'5\',
    \'httpversion\' => \'1.0\',
    \'blocking\' => true,
    \'headers\' => array(),
    \'cookies\' => array()
);

$response = wp_remote_get( \'https://www.googleapis.com/books/v1/volumes?q=search+terms\', $args );

if( is_wp_error( $response ) ) {
   $error_message = $response->get_error_message();
   echo "Something went wrong: $error_message";
} else {
   echo \'Response:<pre>\';
   print_r( $response );
   echo \'</pre>\';
}

这始终返回400错误。如果我把我的$body 它完美返回的数组（albiet没有任何自定义参数）。以下是Google生成的错误：

Array
(
    [headers] => Array
        (
            [content-type] => text/html; charset=UTF-8
            [content-length] => 925
            [date] => Thu, 07 Feb 2013 15:09:24 GMT
            [server] => GFE/2.0
        )

    [body] => 





  Google


400. That’s an error.

Your client has issued a malformed or illegal request. That’s all we know. [response] => Array ( [code] => 400 [message] => Bad Request ) [cookies] => Array ( ) [filename] => ) 

以下是正确返回的示例：

Array

    [headers] => Array
        (
