angularjs http post bad request 400

Question

I am sending a post request with $http:

$http({
    method: 'Post',
    url: urlBuilt,        
    headers: {'Content-Type': 'application/json'},                                                         
    params: {"colCode":modCodeCol,"whereClause":clause}
});

When the where clause is very huge, I am getting bad request 400 error. When the where clause contains a small string it works. How can we fix this.

coud you share an example of data to whereClause ???

Try change params to data in the block of http like this.

$http({
    method: 'POST',
    url: urlBuilt,        
    headers: {'Content-Type': 'application/json'},                                                         
    data:{"colCode":modCodeCol,"whereClause":clause}
});

params if for queryParams it mean it send on the url. data appends to the request body.

@Carrasco, I used data, and in my spring contoller I have changed requestParam to requestBody like below,the request sent by the client was syntactically incorrect

for POST request you need to send data as JSON also it's better to Get a promise and resolve it after send the request like this :

  var data = {
               "colCode":modCodeCol,
               "whereClause":clause 
             }
  $http({ url: urlBuilt , method: 'POST', data: data })
        .then(function (result) {
            deferred.resolve({ data: result.data.Data, count: result.data.Count });

        });
