问题 I need to make a POST request via Curl from the command line. Data for this request is located in a file. I know that via PUT this could be done with the --upload-file option. curl host:port/post-file -H "Content-Type: text/xml" --data "contents_of_file" 回答1: You're looking for the --data-binary argument: curl -i -X POST host:port/post-file \ -H "Content-Type: text/xml" \ --data-binary "@path/to/file" In the example above, -i prints out all the headers so that you can see what's going on, and

问题 I'm POSTing data to an external API (using PHP, if it's relevant). Should I URL-encode the POST variables that I pass? Or do I only need to URL-encode GET data? Thanks! UPDATE: This is my PHP, in case it is relevant: $fields = array( 'mediaupload'=>$file_field, 'username'=>urlencode($_POST["username"]), 'password'=>urlencode($_POST["password"]), 'latitude'=>urlencode($_POST["latitude"]), 'longitude'=>urlencode($_POST["longitude"]), 'datetime'=>urlencode($_POST["datetime"]), 'category'=

问题 NOTE : I've never written vb.net code before this. I've googled for a solution but did not find anything that worked. I'm trying to get access token from Salesforce. Below code worked just yesterday . And I have no idea why it is not working today. I've tried adding content-type as application/x-www-form-urlencoded but it did not work either. When I use curl I'm able to get access token. Also I'm able to get access token using advanced rest client in google chrome. Any ideas why it is

问题 I want to access a http.Request 's Body multiple times. The first time happens in my authentication middleware, it uses it to recreate a sha256 signature. The second time happens later, I parse it into JSON for use in my database. I realize that you can't read from an io.Reader (or an io.ReadCloser in this case) more than once. I found an answer to another question with a solution: When you first read the body, you have to store it so once you're done with it, you can set a new io.ReadCloser
