-A auth-Username:password provides a Basic authentication trust to the server. The user name and password are separated by a: and sent in Base64 encoded form, regardless of whether the server is required (that is, whether the 401 authentication requirement code is sent), this string will be sent-c concurrency The number of requests produced at a time, the default is one at a time.-C cookie-name=value appends a cookie line to the request. Its typical form is name=a parameter pair for value. This parameter can be repeated-d does not show"Percentage served within xxx[ms] table"the message-E csv-fileproduces a comma-delimited (CSV) file that contains the required processing of requests for each corresponding percentage (from 1% to 100%) of the corresponding percentage (in subtle units) of the time. Since this format has been" Binary", so than'gnuplot'format more useful-G gnuplot-fileWrite all test results to a'gnuplot'or a TSV (tab-delimited) file. This file can be easily imported into Gnuplot,idl Mathematica,lgor or even Excel. First behavior title-h Help-H custon-The header appends additional header information to the request, and the typical form of this parameter is a valid header information line that contains a colon-delimited pair of fields and values (for example,"Accept-encoding:zip/zop;8bit")-I perform a head request, not a get.-K enables the HTTP keepalive feature, that is, to execute multiple requests in an HTTP session. By default, the KeepAlive feature is not started-N Requests the number of requests executed in the test session. By default, only one request is executed, but usually the result does not represent meaning-P post-filecontains files that require post data.-P proxy-auth-Username:password provides basic authentication trust to a secondary school agent.-A-Q If the number of requests processed is greater than, AB is processed approximately ten% or 100 requests, a progress count is output at stderr, this-Q Mark to make this information-s used in the compilation (AB-h will show relevant information) using SSL protected HTTPS, rather than the HTTP protocol, this feature is experimental and very rudimentary, preferably not used.-S does not display median and standard divergence values, and it is worth 1 to twice times when the mean and median values are standard deviations, and no warning or error message is displayed, and the minimum value is displayed by default/Mean/Values such as maximum value (supported for previous versions)-The maximum number of seconds that the T timelimit Test takes, and the internal implied value is-N50000. It can limit the testing of the server to a fixed total time. By default, there is no time limit-T content-Type the content used by the post data-Type header information.-v verbosity Set the detail level of the display information-A value of 4 or greater displays the header information, and 3 or greater values can display the response code (404, 200, etc.), 2 or greater can display warnings and other information-Woutputs the result in the format of an HTML table. By default, it is a table of two column widths of white background.-X <table>-Attributes SettingsThe string for the <table> property. This property is filled in <table here >-X proxy[:p ort] Use a proxy server for requests-Y <TR>-Attributes Settings<TR>the string for the property.-Z <td>-attrributes Settings<td>the string for the property.
