The difference between body and query parameters in front-end post requests

The most commonly used front-end requests are get requests and post requests
Get request can only pass query parameters, query parameters are all spelled on the request address
post can pass parameters in two forms: body and query
as follows:

/* Edit item list */
export function editProjectList(params) {
  const url = '/support/project/update';
  return request({
    url: url,
    method: 'put',
    data: params // data is the body parameter
  });
}

/* Add customer list */
export function addClientList(params) {
  const url = '/support/company/insert';
  return request({
    url: url,
    method: 'post',
    params: params// params are query parameters
  });
}

Note: The parameter passing on the request address is the query passing parameter. The value of params can only be a string, and the parameter of the object type cannot be passed. If the passing object is involved in the parameter, the body passing parameter must be selected.
