使用 PHP 发布到 Blogger [英] Posting to Blogger using PHP

问题描述

我在使用 PHP 的 Blogger API 时遇到问题.

I'm having a problem getting the Blogger API for PHP to work.

我需要的是能够将新博文发布到我的博客帐户.我使用的代码取自此处的 Google API 页面:http://code.google.com/intl/nl/apis/blogger/docs/1.0/developers_guide_php.html

What I need is to be able to post a new blogpost to my bloggeraccount. The code I'm using is taken from the Google API page here : http://code.google.com/intl/nl/apis/blogger/docs/1.0/developers_guide_php.html

这是我的代码:

<?
require_once 'Zend/Loader.php';
Zend_Loader::loadClass('Zend_Gdata');
Zend_Loader::loadClass('Zend_Gdata_Query');
Zend_Loader::loadClass('Zend_Gdata_ClientLogin');

$user = '[e-mail]';
$pass = 'password';
$service = 'blogger';

$client = Zend_Gdata_ClientLogin::getHttpClient($user, $pass, $service, null,
        Zend_Gdata_ClientLogin::DEFAULT_SOURCE, null, null, 
        Zend_Gdata_ClientLogin::CLIENTLOGIN_URI, 'GOOGLE');
$gdClient = new Zend_Gdata($client); 

$blogID = '7973737751295446679';

function createPublishedPost($title='Hello, world!', $content='I am blogging on the internet.')
{
  $uri = 'http://www.blogger.com/feeds/' . $blogID . '/posts/default';
  $entry = $gdClient->newEntry();
  $entry->title = $gdClient->newTitle($title);
  $entry->content = $gdClient->newContent($content);
  $entry->content->setType('text');

  $createdPost = $gdClient->insertEntry($entry, $uri);
  $idText = split('-', $createdPost->id->text);
  $newPostID = $idText[2]; 

  return $newPostID; 
}

createPublishedPost();
?>

我得到的错误是致命错误:调用 C:\xampp\htdocs\HelloWorld\blogger2.php 中第 21 行的非对象上的成员函数 newEntry()"

The error I'm getting is 'Fatal error: Call to a member function newEntry() on a non-object in C:\xampp\htdocs\HelloWorld\blogger2.php on line 21'

谁能帮助我或给我一个关于如何使用 PHP 向博主发帖的工作代码示例?

Can anyone help me out or give me a working code sample of how to post to blogger using PHP ?

推荐答案

您的 $gdClient 变量在 createPublishedPost 函数之外被初始化:

Your $gdClient variable is intanciated outside of the createPublishedPost function :

$gdClient = new Zend_Gdata($client); 

在函数内部，在函数外部定义的变量默认不存在.
关于这个，你可以看看变量范围 手册页.

Inside a function, the variables that have been defined outside of it don't exist by default.
About that, you can take a look at the Variable scope page of the manual.

这意味着 $gdClient 在函数内部不存在；因此，它是 null ；所以，不是一个对象——它解释了你得到的错误信息.

This means $gdClient doesn't exist inside the function ; hence, it is null ; so, not an object -- which explains the error message you are getting.

要自己检查，您可以使用

To check that by yourself, you can use

var_dump($gdClient);

在函数的开头:它会让你看到它是什么类型的数据；如果它不是您愿意使用的类的实例，这不是一个好兆头 ;-)

at the beginning of the function : it will allow you to see what kind of data it is ; if it's not an instance of the class you are willing to use, it's not a good sign ;-)

您可能想要:

• 将该变量作为参数传递给 createPublishedPost 函数
• 或声明为global 函数内部(这样函数就可以看到"外部声明的变量)

我认为第一个解决方案可能是最干净的解决方案;-)

The first solution is probably the cleanest one, I think ;-)

作为旁注，您可能想要配置您的 error_reporting 级别(另见)，所以当你使用一个未声明的变量时你会得到一个 E_NOTICE——在这种情况下，你应该得到一个，例如;-)
您可能还想启用 display_errors，在您的开发机器上，如果它尚未打开 - 似乎是，因为您收到了致命错误消息

As a sidenote, you might want to configure your error_reporting level (see also), so you get an E_NOTICE when you are using a variable that is not declared -- in this case, you should have gotten one, for instance ;-)
You might also want to enable display_errors, on your development machine, if it's not already on -- seems to be, as you got the Fatal error message

一开始可能看起来有点烦人，但是，一旦你习惯了它，它真的很棒:可以更快地检测到那种东西;-)
它还有助于检测变量名称中的拼写错误^^
它让你的代码更简洁！

It might seem a bit annoying at the beginning, but, once you get used to it, it is really great : allow to detect that kind of stuff a lot quicker ;-)
And it also helps detect typos in variable names ^^
And it makes you code way cleaner !
