PHP: Using cURL with Basic HTTP Authentication.
This is a short PHP tutorial on how to use cURL to make a Basic Access Authentication request. In this post, I will show you how to configure PHP’s cURL functions to access a web resource that is protected by basic HTTP authentication.
401 Unauthorized.
If you send a cURL request to a URL that is protected by HTTP authentication, the response will probably look something like this:
401 Unauthorized: You need a valid user and password to access this content.
The issue here is that the resource is protected and you did not provide a valid username and password. As a result, the server responded with a 401 Unauthorized response.
Using the CURLOPT_USERPWD option.
To solve this, we can use the CURLOPT_USERPWD option. This option allows us to tell cURL what username and password to use while making the request.
An example of it being used:
Pretty simple, right?
In the example above, we set the username and password using the CURLOPT_USERPWD option. As a result, our cURL client will end up sending the following header:
Using CURLOPT_HTTPHEADER.
Alternatively, you can use the CURLOPT_HTTPHEADER, which allows you manually create headers. In the example below, we manually set the Content-Type and Authorization headers:
The code above should be used in lieu of the CURLOPT_USERPWD option.
Hopefully, you found this guide to be useful!

See part 6. HTTP Authentication
HTTP Authentication is the ability to tell the server your username and password so that it can verify that you’re allowed to do the request you’re doing. The Basic authentication used in HTTP (which is the type curl uses by default) is plain text based, which means it sends username and password only slightly obfuscated, but still fully readable by anyone that sniffs on the network between you and the remote server.
To tell curl to use a user and password for authentication:
Sometimes your HTTP access is only available through the use of a HTTP proxy. This seems to be especially common at various companies. A HTTP proxy may require its own user and password to allow the client to get through to the Internet. To specify those with curl, run something like:
If you use any one these user+password options but leave out the password part, curl will prompt for the password interactively.
Do note that when a program is run, its parameters might be possible to see when listing the running processes of the system. Thus, other users may be able to watch your passwords if you pass them as plain command line options. There are ways to circumvent this.
It is worth noting that while this is how HTTP Authentication works, very many web sites will not use this concept when they provide logins etc. See the Web Login chapter further below for more details on that.
How do I make a request using HTTP basic authentication with PHP curl?
I’m building a REST web service client in PHP and at the moment I’m using curl to make requests to the service.
How do I use curl to make authenticated (http basic) requests? Do I have to add the headers myself?

Zend has a REST client and zend_http_client and I’m sure PEAR has some sort of wrapper. But its easy enough to do on your own.
So the entire request might look something like this:
CURLOPT_USERPWD basically sends the base64 of the user:password string with http header like below:
So apart from the CURLOPT_USERPWD you can also use the HTTP-Request header option as well like below with other headers:
The most simple and native way it’s to use CURL directly.
You just need to specify CURLOPT_HTTPAUTH and CURLOPT_USERPWD options:
Unlike SOAP, REST isn’t a standardized protocol so it’s a bit difficult to have a «REST Client». However, since most RESTful services use HTTP as their underlying protocol, you should be able to use any HTTP library. In addition to cURL, PHP has these via PEAR:
A sample of how they do HTTP Basic Auth
The also support Digest Auth
If the authorization type is Basic auth and data posted is json then do like this
Other way with Basic method is:
For those who don’t want to use curl:
Yahoo has a tutorial on making calls to their REST services using PHP:
I have not used it myself, but Yahoo is Yahoo and should guarantee for at least some level of quality. They don’t seem to cover PUT and DELETE requests, though.
Also, the User Contributed Notes to curl_exec() and others contain lots of good information.

How do I set up the basic authorization?
)? What I’m trying to unserstand is the meaning of symbols that follow the «Basic» word 🙂
Here, BASE64_string = Base64 of username:password
Background
You can use the base64 CLI tool to generate the base64 encoded version of your username + password like this:
Base64 is reversible so you can also decode it to confirm like this:
NOTE: username = joeuser, password = secretpass
You can put this together into curl like this:
But you can do this in a semi-safer manner if you keep your credentials in a encrypted vault service such as LastPass or Pass.
When used, your details remain hidden, since they’re passed to curl via a temporary file descriptor, for example:

HTTP Basic Authorization
The methods shown above are facilitating a feature known as Basic Authorization that’s part of the HTTP standard.
When the user agent wants to send authentication credentials to the server, it may use the Authorization field.
The Authorization field is constructed as follows:
For example, if the browser uses Aladdin as the username and OpenSesame as the password, then the field’s value is the base64-encoding of Aladdin:OpenSesame, or QWxhZGRpbjpPcGVuU2VzYW1l. Then the Authorization header will appear as:
Authorization: Basic QWxhZGRpbjpPcGVuU2VzYW1l

см. раздел 6. Аутентификация HTTP
аутентификация HTTP-это возможность сообщить серверу свое имя пользователя и пароль, чтобы он мог подтвердить, что вам разрешено выполнять запрос, который вы делающий. Базовая аутентификация, используемая в HTTP (который является типом, используемым curl по умолчанию)простые текст, что означает, что он отправляет имя пользователя и пароль только слегка запутанный, но все еще полностью читаемый любым, кто нюхает сеть между вами и удаленным сервером.
чтобы сказать curl использовать пользователя и пароль для аутентификации:
Иногда ваш HTTP-доступ доступен только через использование HTTP полномочие. Это, по-видимому, особенно распространено в различных компаниях. Прокси HTTP может потребоваться собственный пользователь и пароль, чтобы позволить клиенту интернет. Чтобы указать те, с завитком, запустите что-то вроде:
Если вы используете любой из этих параметров user + password, но оставляете пароль часть, curl запросит пароль в интерактивном режиме.
обратите внимание, что при запуске программы ее параметры могут быть видны при перечислении запущенных процессов системы. Таким образом, другие пользователи могут быть возможность просмотра паролей, Если вы передаете их как обычную командную строку опции. Есть способы обойти это.
стоит отметить, что пока это так HTTP Аутентификация работает, очень многие веб-сайты не будут использовать эту концепцию, когда они дают логины и т. д. Видеть более подробная информация об этом приведена ниже в разделе веб-входа.
