Upload Method 1

Convert the uploaded file to data and upload it

    //1. Create a managerAfhttprequestoperationmanager *mgr = [Afhttprequestoperationmanager manager];//2. Package parameters (this dictionary can only put non-file parameters)    nsmutabledictionary*params = [nsmutabledictionaryDictionary]; params[@"username"] = @"123"; params[@"Age"] = @ -; params[@"PWD"] = @"456"; params[@"Height"] = @1.55;//2.

Upload Method 2

Get the file you want to upload directly with the URL

    //1. Create a managerAfhttprequestoperationmanager *mgr = [Afhttprequestoperationmanager manager];//2.
