Attempting to use invalid JSON in Ruby? -

I am trying to test a test that returns a valid JSON 400 error code to a cURL request is. Unfortunately, Ruby will not allow me to use invalid JSON.

  if bad_json credentials = {"username" = & gt; Username "password" = & gt; Password} .to_json other credentials = {"username" = & gt; Username, "password" = & gt; Password} .to_json end   
 When I try to run the test, it produces the following:  
  /foo.rb:60: Syntax Error, unexpected tSTRING_BEG, expected '}' "password" = & gt; Password ^ /foo.rb:60: Syntax error, unexpected =>, Except keyword_end "password" = & gt; Is it possible to pass invalid JSON passwords without breaking the script?  
 
 As others have commented that your Ruby has syntax errors, you must have a valid Ruby And if I understand your problem properly, then make errors in JSON.  
 Specifically, you are asking Ruby to make a hash, then convert it to a string in which the compliance treaty is made directly with JSON Speck, just make that text directly, then you control You can do it how closely it conforms. \ "# {Username} \" \ "password \": \ "# {password} \"} "Other credentials =" "if the bad_json credentials =" {\ "username" "{\" User Name \ ": \" # {username} \ ", \" password \ ": \" # {password} \ "}" end   
  edit  - More details  
 To make this point more clear here is a simple example in irb / pry:  
  [1] ) & gt; {} .class = & gt; Hash [2] PRI (Main) & gt; {} .to_json = & gt; "{}" [3] Pvt (main) & gt; {} .to_json.class = & gt; String [4] Pvt (main) & gt; "{}". Class = & gt; Here we can see that to_json gives only one string, so if you can create strings by yourself which is Confirmed JSON, then it will be as good as string JSON Make processor.
