在Erlang中使用httpc:request实现HTTP POST文件的方法如下:
-include_lib("inets/include/http.hrl").
Url = "http://example.com/upload",
Headers = [{"Content-Type", "multipart/form-data"}],
Body = {file, "/path/to/file.txt", "text/plain"}.
{ok, {{_, 200, _}, _, ResponseBody}} = httpc:request(post, {Url, Headers, Body}, [], []).
这里的{Url, Headers, Body}
是HTTP POST请求的参数,[]
是请求的选项,[]
是请求的配置。
io:format("Response: ~p~n", [ResponseBody]).
完整的示例代码如下:
-include_lib("inets/include/http.hrl").
post_file() ->
Url = "http://example.com/upload",
Headers = [{"Content-Type", "multipart/form-data"}],
Body = {file, "/path/to/file.txt", "text/plain"},
{ok, {{_, 200, _}, _, ResponseBody}} = httpc:request(post, {Url, Headers, Body}, [], []),
io:format("Response: ~p~n", [ResponseBody]).
请注意,这只是一个简单的示例,实际应用中可能需要处理更多的错误情况和异常情况。
