输出为null,PHP版本为5.6。我将该行添加到了PHP.INI文件中。 我已经尝试使用HTTP和HTTP,但是它仍然显示null。我更新了主机地址,以包含API调用URL,如azure控制面板中所示。并且没有太多关于人们收到此错误的信息。

答案 0 :(得分:0)
众所周知,您的代码是从官方文档Quickstart: Translate text with the Translator Text REST API (PHP)
复制而来的。
根据引用Translator Text API v3.0
的{{3}}部分,$host
值应为以下列表之一。
因此,您可以在代码中使用$host = "https://api.cognitive.microsofttranslator.com";
,而无需进行任何更改。这是第一个问题。
第二,标头取决于您的Cognitive Services订阅的API类型。
Translator Text
,如下图所示,您将不会更改源代码的函数$headers
中的任何Translate
代码,该代码取决于您的位置,例如为southeastasia
。All Cognitive Services
,如下图所示,则需要在Ocp-Apim-Subscription-Region
代码中添加标头$headers
。$headers = "Content-type: application/json\r\n" .
"Content-length: " . strlen($content) . "\r\n" .
"Ocp-Apim-Subscription-Key: $key\r\n" .
"Ocp-Apim-Subscription-Region: southeastasia\r\n" .
"X-ClientTraceId: " . com_create_guid() . "\r\n";
然后,在我的环境中,PHP版本为7.2.12
,我运行php -f test.php
可以正常工作,并针对上述两种不同情况返回json响应,如下所示。
