Today, I will talk to you about the steps of CloudStack API request generation, which may not be well understood by many people. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

Public interface ApiInterface {/ * ApiKey*/ public final String ApiKey = "lK_xPFYay2H_saCR3tGPcnVcSJfmg8kL-43WzXsLUXFs7lPeE0yTQjSPxQ" assigned by cloudStack users; / * SecretKey*/ public final String SecretKey = "- o8m4PbZQjHleMGThorRtyO71qVeZWyBHP92nFZ09uE2SaayizgF0oA" assigned by cloudStack users / * steps to generate signature * Command String (command string) contains command name, parameter and API Key. Parameter name is case-insensitive, but parameter value is sensitive * 1: URL encode each parameter value in the sorted command string * * / String encodeParameters (String parameters) / * * 2: sort the entire command string to "parameters" alphabetically * * / String sortParameters (String parameters); / * * 3: lowercase convert the sorted command string to lowercase * * / String ToLower (String Command) / * * 4: convert the lowercase strings Command and Secret Key to HMAC SHA-1 hash calculation, and then encode the result with Base64 (utf-8) to generate Signature * * / String sign (String command, String secretKey); / * * 5: merge to generate a complete URL= Base URL + API Path + Command String + Signature * / String combine (String baseURL, String apiPath, String command, String signature) / * * simulate the request and get response * * / InputStream getResponse (String URL); / * * parse the value of response * * / Map getSingleValueFromXML (InputStream inputStream, String [] tagNames);} after reading the above, do you have any further understanding of the steps for generating CloudStack API requests?
