尝试获取getDefinitions时出现Wordnik“尝试获取非对象的属性”错误
[英]Wordnik “Trying to get property of non-object” Error when trying getDefinitions
问题描述
I'm trying to use the Wordnik PHP API and I'm having some trouble. 
我正在尝试使用Wordnik PHP API，但遇到了一些麻烦。 I tried to use the getDefinitions method but it returns an error: Notice: Trying to get property of non-object in C:\\xampp\\htdocs\\index.php on line 18 . 我尝试使用getDefinitions方法，但返回错误： Notice: Trying to get property of non-object in C:\\xampp\\htdocs\\index.php on line 18 。
Here is the following code: 这是下面的代码：
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<form method="post">
<input type="text" placeholder="First Word" name="word1">
<input type="submit" placeholder="Compare">
</form>
<?php
require('./wordnik/Swagger.php');
$APIKey = '342eac9900e703079b0050d5f7008eab962195189e75bfbcb';
$client = new APIClient($APIKey, 'http://api.wordnik.com/v4');
$word1 = $_POST['word1'];
$wordApi = new WordApi($client);
$word1 = $wordApi->getDefinitions($word1, null, null);
print $word1->text;
?>
</body>
</html>

I think your notice (not really an error in the php world) does not come from the $word1 = $wordApi->getDefinitions($word1, null, null); 我认为您的通知（实际上不是php世界中的错误）不是来自$word1 = $wordApi->getDefinitions($word1, null, null); but from print $word1->text; 但从print $word1->text; is it possible? 可能吗？
If you check the WorldApi class : 如果您检查WorldApi类：
https://github.com/wordnik/wordnik-php/blob/master/wordnik/WordApi.php#L182 https://github.com/wordnik/wordnik-php/blob/master/wordnik/WordApi.php#L138 https://github.com/wordnik/wordnik-php/blob/master/wordnik/WordApi.php#L182 https://github.com/wordnik/wordnik-php/blob/master/wordnik/WordApi.php#L138
You can see that getDefinitions(...) return an array of Definition or null. 您可以看到getDefinitions(...)返回一个Definition数组或null。
One thing is sure, you cannot get the ->text property from $word1 but from one of these indexes if the return is valid. 可以肯定的是，如果返回有效，则不能从$word1获得->text属性，而是从这些索引之一中获得。 Try $word1[0]->text 尝试$word1[0]->text
Anyway you should also handle the case where the return of getDefinitions(...) return an empty array or null. 无论如何，您还应该处理以下情况： getDefinitions(...)返回返回空数组或null。

This sample code might help you: 此示例代码可能会帮助您：
apiUrl = 'http://api.wordnik.com/v4'
apiKey = 'YOURKEYHERE'
client = swagger.ApiClient(apiKey, apiUrl)
wordApi = WordApi.WordApi(client)
res = wordApi.getWord('cat')
res2 = wordApi.getDefinitions('cat')
assert res, 'null getWord result'
assert res.word == 'cat', 'word should be "cat"'
print res.word
print dir(res2[0])
print res2[0].partOfSpeech
