问题描述
我正在尝试使用HttpRequest类,该类应该在php的PECL_HTTP扩展名中.我有php5,并使用以下代码安装pecl_http.
I am trying to use the HttpRequest class which should be in the PECL_HTTP extension of php.I have php5 and used the following to install pecl_http.
sudo pecl install pecl_http
pecl/pecl_http is already installed and is the same as the released version 2.0.1
install failed
之后,我进入我的php.ini:
After that i enter into my php.ini:
[PHP]
extension=http.so
[...]
然后,我重新启动apache2服务器,并尝试使用HttpRequest类,但这会给我以下错误:
Then i restart my apache2 server, and try using the HttpRequest class, but it gives me the following error:
PHP Fatal error: Class 'HttpRequest' not found
我可能错过了哪些可能的错误?
What are possible error's i might have missed?
更新 :(已更改标题)
扩展名未显示在phpinfo()中,我已设置
The Extension is not shown in phpinfo(), i set
extension=http.so
并检查 http.so
文件是否在我的 extension_dir
中.我真的不知道如何使php识别扩展名.
And checked if the http.so
file is in my extension_dir
. I really don't know how to make php recognise the extension.
更新2 :我设法安装了扩展程序,但是该类仍然不存在.对于其他人,我不得不参考pecl_http需要的其他扩展.(对我来说: propro.so
, raphfr.so
)
UPDATE 2:I managed to install extension, but the class still does not exist.For others, i had to reference the other extensions pecl_http needs. (For me: propro.so
, raphfr.so
)
更新3 :我没有使班级可见,下面的答案显示了其他班级的一些方法.
UPDATE 3:I did not manage to make the Class visible, the answers below show some approaches with other classes.
我通过使用CURL解决了此问题.
I solved this issue by using CURL.
推荐答案
您已经安装了使用完全不同的API的扩展的新版本.我仍然不知道它是如何工作的,但是我将更新我知道的答案.新版本的文档位于 http://devel-m6w6.rhcloud.com/mdref/http .
You have installed the new version of the extension which uses a completely different API. I still don't know how it works, but I will update my answer one I know. The Documentation of the new version is to be found at http://devel-m6w6.rhcloud.com/mdref/http.
要安装旧版本,请先卸载新版本,然后执行
To Install the old version, first uninstall the new verion and then execute
pecl install http://pecl.php.net/get/pecl_http-1.7.6.tgz
更新:以下是文档中的两个示例,两个示例都可以很好地工作:
UPDATE: here are two examples from the documentation, both should work well:
一个请求(可以在 http://devel-m6w6.rhcloud中找到.com/mdref/http/Client/enqueue ):
<?php
(new http\Client)->enqueue(new http\Client\Request("GET", "http://php.net"),
function(http\Client\Response $res) {
printf("%s returned %d\n", $res->getTransferInfo("effective_url"), $res->getResponseCode());
return true; // dequeue
})->send();
多个请求(可以在 http://devel-m6w6.rhcloud中找到.com/mdref/http/Client/once ):
<?php
$client = new http\Client;
$client->enqueue(new http\Client\Request("HEAD", "http://php.net"));
$client->enqueue(new http\Client\Request("HEAD", "http://pecl.php.net"));
$client->enqueue(new http\Client\Request("HEAD", "http://pear.php.net"));
printf("Transfers ongoing");
while ($client->once()) {
// do something else here while the network transfers are busy
printf(".");
// and then call http\Client::wait() to wait for new input
$client->wait();
}
printf("\n");
while ($res = $client->getResponse()) {
printf("%s returned %d\n", $res->getTransferInfo("effective_url"),
$res->getResponseCode());
}
在两个示例中,您都可以使用 $ res-> getBody()
返回响应的正文.
In both examples you can use $res->getBody()
to return the body of the response.
我无法测试这些示例,但我听说其他人也可以使用.
I couldn't test these examples but I have heard of other people that they work.
