Tag <CFHTTP>

Lets you execute HTTP POST and GET operations on files. Using cfhttp, you can execute standard GET operations and create a query object from a text file. POST operations lets you upload MIME file types to a server, or post cookie, formfield, URL, file, or CGI variables directly to a specified server.

Attributes

The attributes for this tag are fixed. Except for the following attributes no other attributes are allowed.
Name Type Required Description
addtoken boolean No if yes add urltoken as cookie 
authtype string No authentication type for a request with username and password, valid values are "BASIC" (default) and "NTLM" 
charset string No set the charset for the call. 
columns string No Specifies the column names for a query when creating a query as a result of a cfhttp GET. 
compression string No Informs the target webserver to disable compression for the response. Possible values are:
  • true (default): compression enabled
  • false: compression disabled
  • none (deprecated): use "false" instead 
    		•
    delimiter string No Used only when creating a query from an http request that returns data in a CSV format. This
    value specifies the Field delimiter for the CSV data. Only the first character is used. Default is a comma. 
    domain string No The domain to authenticate within. this attribute is only used when authenication type is "NTLM" 
    encodeurl boolean No if set to true (default value) URL encodes the value of the attribute "URL" if necessary (no double encoding is happeing).
    This setting has no influence on the values from httpparam type="url", for this use the attribute "encoded" from httpparam 
    file string No The filename to be used for the file that is accessed. For GET operations, defaults to the name
    specified in url. Enter path information in the path attribute. 
    firstrowasheaders boolean No sets if first row of csv is file 
    getasbinary string No - false: If CFML does not recognize the response body type as text, convert it to a CFML object.
  • auto: If CFML does not recognize the response body type as text, convert it to CFML Binary type data.
  • true: always convert the response body content into CFML Binary type data, even if CFML recognizes the response body type as text. 
    		•
    method string No GET or POST. Use GET to download a text or binary file or to create a query from the contents
    of a text file. Use POST to send information to a server page or a CGI program for processing. POST
    requires the use of a cfhttpparam tag. 
    multipart boolean No Tells Lucee to send all data specified by cfhttpparam type="formField" tags as multipart form data, with a Content-Type of multipart/form-data. 
    multiparttype string No This Attribute is deprecated 
    name string No The name to assign to a query if the a query is constructed from a file. 
    password string No When required by a server, a valid password. 
    path string No The path to the directory in which a file is to be stored. If a path is not specified in a POST
    or GET operation, a variable is created (cfhttp.fileContent) that you can use to display the results
    of the POST operation in a cfoutput. 
    port number No The port number on the server from which the object is requested. Default is 80. When used with
    resolveURL, the URLs of retrieved documents that specify a port number are automatically resolved to
    preserve links in the retrieved document. If a port number is specified in the url attribute, the port
    value overrides the value of the port attribute. 
    preauth boolean No if set to true (default), Lucee sends the basic authentication (username password) always (Preemptive Basic Authentication),
    if set to false the authentication is only send when the server ask for it (status code 401). 
    proxypassword string No When required by a proxy server, a valid password. 
    proxyport number No The port number on the proxy server from which the object is requested. Default is 80. When
    used with resolveURL, the URLs of retrieved documents that specify a port number are automatically
    resolved to preserve links in the retrieved document. 
    proxyserver string No Host name or IP address of a proxy server. 
    proxyuser string No When required by a proxy server, a valid username. 
    redirect boolean No Boolean indicating whether to redirect execution or stop execution. The default is Yes. If set
    to No and throwOnError = "yes", execution stops if cfhttp fails, and the status code and associated
    error message are returned in the variable cfhttp.statuscode. To see where execution would have been
    redirected, use the variable cfhttp.responseHeader[LOCATION]. The key LOCATION identifies the path of
    redirection. Lucee will follow up to five redirections on a request. if this limit is exceeded,
    Lucee behaves as if redirect = "no". 
    resolveurl boolean No Yes or No. Default is No. For GET and POST operations, if Yes, page reference returned into the
    fileContent internal variable has its internal URLs fully resolved, including port number, so that
    links remain intact. 
    result string No return variable name, default "cfhhtp" 
    textqualifier string No Required for creating a query. Indicates the start and finish of a column. Should be
    appropriately escaped when embedded in a column. For example, if the qualifier is a double quotation
    mark, it should be escaped as """". If there is no text qualifier in the file, specify it as " ".
    Default is the double quotation mark ("). 
    throwonerror boolean No Boolean indicating whether to throw an exception that can be caught by using the cftry and
    cfcatch tags. The default is NO. 
    timeout any No A value, in seconds or a TimeSpan object. When a URL timeout is specified in the browser, the timeout attribute setting
    takes precedence over the Lucee Administrator timeout. The server then uses the lesser
    of the URL timeout and the timeout passed in the timeout attribute, so that the request always times
    out before or at the same time as the page times out. If there is no URL timeout specified, Lucee
    takes the lesser of the Lucee Administrator timeout and the timeout passed in the timeout attribute.
    If there is no timeout set on the URL in the browser, no timeout set in the Lucee Administrator,
    and no timeout set with the timeout attribute, Lucee waits indefinitely for the cfhttp request to
    process. 
    url string Yes Full URL of the host name or IP address of the server on which the file resides. The URL must be
    an absolute URL, including the protocol (http or https) and hostname. It may optionally contain a port
    number. Port numbers specified in the url attribute override the port attribute. 
    useragent string No User agent request header. 
    username string No When required by a server, a valid username. 
    workstation string No The workstation the authentication request is originating from. Essentially, the computer name for this machine. this attribute is only used when authenication type is "NTLM"
