To avoid this problem, the -ignore-stdin flag should be used in scripts, unless data is being piped to HTTPie. But, since there is neither any input data nor an end-of-file ( EOF) signal, HTTPie gets stuck. When stdin is redirected, HTTPie assumes that the input will contain the request body, and it waits for the input to be provided. This means that the rules for redirected input will be followed. This happens because, in situations where HTTPie is invoked outside of an interactive session, such as from a cron job, stdin is not connected to a terminal. It's important to note that without the -ignore-stdin option, HTTPie may appear to have stopped working (hang). You most likely want to use the -ignore-stdin option to disable it. The default behavior of automatically reading stdin is typically not desirable during non-interactive invocations. The -stream option is automatically enabled when the response headers include Content-Type: text/event-stream. This makes it possible to have a nice output for long-lived requests, such as one to the Twitter streaming API. Streaming becomes enabled even when the output is prettified: It will be applied to each line of the response and flushed immediately.The output is flushed in much smaller chunks without any buffering, which makes HTTPie behave kind of like tail -f for URLs.You can use the -stream, -S flag to make two things happen: However, when colors and formatting are applied, the whole response is buffered and only then processed at once. This allows for streaming and large file downloads without using too much memory. Responses are downloaded and printed in chunks. Accept-Encoding can’t be set with -download.

There are multiple useful ways to use piping: Or -compress, -x to compress the request body. You may also use -chunked to enable streaming via chunked transfer encoding If you provide Content-Length, then the request body is streamed without buffering. The universal method for passing request data is through redirected stdinīy default, stdin data is buffered and then with no further processing used as the request body. There are three methods for passing raw request data: piping via stdin, These two approaches for specifying request data (i.e., structured and raw) cannot be combined. In addition to crafting structured JSON and forms requests with the request items syntax, you can provide a raw request body that will be sent without further processing. The response headers are downloaded always, even if they are not part of the output Raw request body Therefore, bandwidth and time isn’t wasted downloading the body which you don’t care about. Since you are only printing the HTTP headers here, the connection to the server is closed as soon as all the response headers have been received. For example instead of using a static string as the value for some header, you can use operator Using file contents as values for specific fields is a very common use case, which can be achieved through adding the suffix to Raw request body is a mechanism for passing arbitrary request data. Note that the structured data fields aren’t the only way to specify request data: For example or With -form, the presence of a file field results in a -multipart request Useful when sending JSON and one or more fields need to be a Boolean, Number, nested Object, or an Array, e.g., meals:='' or pies:= (note the quotes)įile upload fields available with -form, -f and -multipart. Request data fields to be serialized as a JSON object (default), to be form-encoded (with -form, -f), or to be serialized as multipart/form-data (with -multipart) X-API-Token:123Īppends the given name/value pair as a querystring parameter to the URL.
