Adding Json data in a variable in ROBOT framework-CodePudding

I am starting to work on automating API requests using ROBOT framework and came across the below issue.

I have this JSON data

{
"password": "123456789",
"username": "[email protected]"
}

I want to put the above in a variable and generate a token as a response.

Previously I had used the below

${body}=  create dictionary       [email protected]     password=123456789

I got the below error response HTTPError: 415 Client Error: Unsupported Media Type for url:

Can someone help me on this please.

Updated Code

*** Settings ***

*** Variables *** 
Credentials 
${prod_url} localhost:3000/api 

*** Test Cases *** 
User login and token generation.

Create Session demo ${prod_url} 

${body}= create dictionary [email protected] password=123456789 

${header}= create dictionary Content-Type=application/json 

${login}= post on session demo /login data=${body} headers=${header} 

log to console ${login.content}

Above is full code. What I need is the username and password needs to be in JSON format because My API is accepting only those values..

CodePudding user response：

Instead of the data argument, try passing the dictionary to the json one:

${login}=  post on session    demo    /login    json=${body}  
  headers=${header}

When you use the data, the library passes as-is the string representation of the object - and in python a str of a dict is {'password': '123456789' ,... - e.g. it uses single quotes, not double ones, which is an invalid json.
Passing the dict to the other argument, json, will make it convert to the proper format.
