Send(<HTTP request> , <WLanguage procedure>)
<HTTP request>: httpRequest variable Name of httpRequest variable containing the characteristics of the HTTP request that will be sent to the server. <WLanguage procedure>: Procedure name Name of WLanguage procedure called during the response from the HTTP server. This procedure has the following format:
PROCEDURE <Procedure name>(<Response> is httpResponse)
where <Response> is an httpResponse variable containing the response received from the HTTP server. Remarks Notes - To find out the runtime errors of this function, use ErrorOccurred and ErrorInfo.
- If the management of cookies is implemented for the specified request (<httpRequest variable>.ManageCookie), the cookies are updated in the httpRequest variable after the call to <httpRequest variable>.Send. Therefore, during the next call to <httpRequest variable>.Send with this request, the cookies will be taken into account.
Versions 21 and laterFrom version 21, the redirections are automatically taken into account in the HTTP requests. To manually process the redirections in the HTTP requests, you must use ..IgnoreError of httpRequest variable associated with the httpIgnoreRedirection constant. New in version 21From version 21, the redirections are automatically taken into account in the HTTP requests. To manually process the redirections in the HTTP requests, you must use ..IgnoreError of httpRequest variable associated with the httpIgnoreRedirection constant. From version 21, the redirections are automatically taken into account in the HTTP requests. To manually process the redirections in the HTTP requests, you must use ..IgnoreError of httpRequest variable associated with the httpIgnoreRedirection constant.   Up to version 23, this function is available only for devices with ARM processors. A fatal error occurs if this function is used with devices not equipped with ARM processors (x86, mips, ...). Up to version 23, this function is available only for devices equipped with ARM processors or an ARM emulator. Otherwise (and on the Samsung Galaxy Tab 3 tablet), a fatal error will occur.
From version 24, devices equipped with x86 processors (therefore Samsung Galaxy Tab 3 tablets) can use this function as well.  Access to REST APIs from a domain other than the one hosting the site from a browser code (Cross-domain) is blocked by default (Cross-Origin Request Blocked). To avoid being blocked, specific authorizations must be configured on the Web server. This topic is covered in the following post on the support blog: https://blogs.pcsoft.fr/fr/autoriser-acces-api-rest-domaine-cors
Security error in a secure transaction During a secure transaction, the request may fail due to security errors: - invalid certificate or certificate coming from an unknown company.
- the site name specified in the certificate does not correspond to a server.
- invalid or expired certificate date.
- redirection to a non-secure server.
If one of these errors occurs, you can re-run the request while ignoring the errors. To do so, all you have to do is modify the ..IgnoreError property of httpRequest variable: | | | Error returned by ErrorInfo
(with the errCode constant) | Value of ..IgnoreError property of httpRequest variable
(these values can be combined) | Description |
|---|
httpErrorInvalidCertificate
Invalid certificate or certificate coming from an unknown company | httpIgnoreInvalidCertificate | The certificate is ignored. | httpErrorInvalidCertificateName
The site name specified in the certificate does not correspond to a server | httpIgnoreInvalidCertificateName | The site name specified in the certificate is ignored. | httpErrorExpiredCertificate
Invalid or expired certificate date | httpIgnoreExpiredCertificate | The certificate date is ignored | httpErrorRedirectToHTTP
Redirection to a non-secure server | httpIgnoreRedirectToHTTP | The redirection to a non-secure server is allowed. | httpIgnoreRedirectToHTTPS
Redirection to a secure server | httpIgnoreRedirectToHTTPS | The redirection to a secure server is allowed. | | httpIgnoreRevocation | The certificate found in the list of revoked certificates is not checked. |
Remarks: - When the HTTP queries are run in several threads, the HTTP.IgnoreError variable has a specific value for each thread.
Versions 22 and later The following errors are supported: httpIgnoreExpiredCertificate, httpIgnoreInvalidCertificate, httpIgnoreInvalidCertificateName, httpIgnoreRevocation, httpIgnoreRedirection. New in version 22 The following errors are supported: httpIgnoreExpiredCertificate, httpIgnoreInvalidCertificate, httpIgnoreInvalidCertificateName, httpIgnoreRevocation, httpIgnoreRedirection. The following errors are supported: httpIgnoreExpiredCertificate, httpIgnoreInvalidCertificate, httpIgnoreInvalidCertificateName, httpIgnoreRevocation, httpIgnoreRedirection.
