Rust: View entire Command::New command arguement structs as its passed to terminal / correct my arguements - linux

Question

I am not getting the correct response from the server running the following
Command::new("curl")
.args(&["-X",
"POST",
"--header",
&("Authorization: Bearer ".to_owned() + &return_token("auth")),
"--header",
"Content-Type: application/json",
"-d",
parameters,
"https://api.tdameritrade.com/v1/accounts/CORRECT_ACCOUNT_#/orders",
])
.output()
.unwrap()
.stdout;
Command::new("curl")
.arg("-X")
.arg("POST")
.arg("--header")
.arg("Authorization: Bearer ".to_owned() + &return_token("auth"))
.arg("--header")
.arg("Content-Type: application/json")
.arg("-d")
.arg(parameters)
.arg("https://api.tdameritrade.com/v1/accounts/CORRECT_ACCOUNT_#/orders")
.output()
.unwrap()
.stdout;
However.... the following works fine if I run it in terminal. I form the following using let line = "curl -X POST --header \"Authorization: Bearer ".to_owned() + &return_token("auth") + "\" --header \"Content-Type: application/json\" -d " + parameters + " \"https://api.tdameritrade.com/v1/accounts/CORRECT_ACCOUNT_#/orders\"";
curl -X POST --header "Authorization: Bearer LONG_RANDOM_AUTH_TOKEN" --header "Content-Type: application/json" -d "{
\"complexOrderStrategyType\": \"NONE\",
\"orderType\": \"LIMIT\",
\"session\": \"NORMAL\",
\"price\": \"0.01\",
\"duration\": \"DAY\",
\"orderStrategyType\": \"SINGLE\",
\"orderLegCollection\": [
{
\"instruction\": \"BUY_TO_OPEN\",
\"quantity\": 1,
\"instrument\": {
\"symbol\": \"SPY_041621P190\",
\"assetType\": \"OPTION\"
}
}
]
}" "https://api.tdameritrade.com/v1/accounts/CORRECT_ACCOUNT_#/orders"
"parameters" can be seen above in JSON.
How can do I view the formation of the command that Command::New is making or correct my args?
EDIT Ive tried using a single quote around the JSON and not escaping the double quotes, which also works in the terminal.
EDIT Example included. I found this : https://github.com/rust-lang/rust/issues/29494 && https://users.rust-lang.org/t/std-process-is-escaping-a-raw-string-literal-when-i-dont-want-it-to/19441/14
However Im in linux...
fn main() {
// None of the following work
let parameters = r#"{"complexOrderStrategyType":"NONE","orderType":"LIMIT","session":"NORMAL","price":"0.01","duration":"DAY","orderStrategyType":"SINGLE","orderLegCollection":[{"instruction":"BUY_TO_OPEN","quantity":1,"instrument":{"symbol":"SPY_041621P190","assetType":"OPTION"}}]}"#;
// OR
let parameters = "'{\"complexOrderStrategyType\":\"NONE\",\"orderType\": \"LIMIT\",\"session\": \"NORMAL\",\"price\": \"0.01\",\"duration\": \"DAY\",\"orderStrategyType\": \"SINGLE\",\"orderLegCollection\": [{\"instruction\": \"BUY_TO_OPEN\",\"quantity\": 1,\"instrument\": {\"symbol\": \"SPY_041621P190\",\"assetType\": \"OPTION\"}}]}'";
// OR
let parameters = "{\"complexOrderStrategyType\":\"NONE\",\"orderType\": \"LIMIT\",\"session\": \"NORMAL\",\"price\": \"0.01\",\"duration\": \"DAY\",\"orderStrategyType\": \"SINGLE\",\"orderLegCollection\": [{\"instruction\": \"BUY_TO_OPEN\",\"quantity\": 1,\"instrument\": {\"symbol\": \"SPY_041621P190\",\"assetType\": \"OPTION\"}}]}";
// OR
let parameters = "{'complexOrderStrategyType':'NONE','orderType': 'LIMIT','session': 'NORMAL','price': '0.01','duration': 'DAY','orderStrategyType': 'SINGLE','orderLegCollection': [{'instruction': 'BUY_TO_OPEN','quantity': 1,'instrument': {'symbol': 'SPY_041621P190','assetType': 'OPTION'}}]}";
println!("{:?}", str::from_utf8(&curl(parameters, "ORDER")).unwrap());
fn curl(parameters: &str, request_type: &str) -> Vec<u8> {
let mut output = Vec::new();
if request_type == "ORDER" {
output = Command::new("curl")
.args(&[
"-X",
"POST",
"--header",
"Authorization: Bearer AUTH_KEY_NOT_INCLUDED",
"--header",
"Content-Type: application/json",
"-d",
parameters,
"https://api.tdameritrade.com/v1/accounts/ACCOUNT_NUMBER_NOT_INCLUDED/orders",
])
.output()
.unwrap()
.stdout;
}
output
}
}

For reasons unknown... changing the --header switch / flag to -H solved the problem. As shown in the following. Spoke with a friend and apparently the shortened form may take different parameters.
let parameters = "{
\"complexOrderStrategyType\": \"NONE\",
\"orderType\": \"LIMIT\",
\"session\": \"NORMAL\",
\"price\": \"0.01\",
\"duration\": \"DAY\",
\"orderStrategyType\": \"SINGLE\",
\"orderLegCollection\": [
{
\"instruction\": \"BUY_TO_OPEN\",
\"quantity\": 1,
\"instrument\": {
\"symbol\": \"SPY_041621P190\",
\"assetType\": \"OPTION\"
}
}
]
}";
Command::new("curl")
.args(&["-X",
"POST",
"-H",
&("Authorization: Bearer ".to_owned() + &return_token("auth")),
"-H",
"Content-Type: application/json",
"-d",
parameters,
"https://api.tdameritrade.com/v1/accounts/ACCOUNT/orders",
])
.output()
.unwrap()
.stdout;
