How to send POST request with parameters and body for JSON data in Swift 3 using Alamofire 4?
Postman api url added below.
Existing code:
let baseUrl = "abc.com/search/"
let param = [
"page":"1",
"size":"5",
"sortBy":"profile_locality"
]
let headers = [
"Content-Type": "application/json"
]
Alamofire.SessionManager.default.request("\(baseUrl)field", method: .post,parameters: param, encoding: JSONEncoding.default, headers: headers).responseJSON { response in
print(response.request ?? "no request") // original URL request
if(response.response?.statusCode != nil){
print("done")
if self.checkResponse(response.response!.statusCode){
let json = JSON(data: response.data!)
//print("at_LeadStop json \(json)")
return completionHandler(json, false)
} else {
return completionHandler(JSON.null, true)
}
} else {
print("gone")
return completionHandler(JSON.null, true)
}}
I don't know how to add body request via this code. Please help me to solve this problem.

Here you mix the two things page
, size
and sortBy
you need to pass a string url as a query string. Now your body is an JSON
Array and you can send an array with using Alamofire
only URLRequest
. So try it like this.
let baseUrl = "abc.com/search/"
let queryStringParam = [
"page":"1",
"size":"5",
"sortBy":"profile_locality"
]
//Make first url from this queryStringParam using URLComponents
var urlComponent = URLComponents(string: baseUrl)!
let queryItems = queryStringParam.map { URLQueryItem(name: $0.key, value: $0.value) }
urlComponent.queryItems = queryItems
//Now make `URLRequest` and set body and headers with it
let param = [
[
"fieldName" : "abc",
"fieldValue":"xyz"
],
[
"fieldName" : "123",
"fieldValue":"789"
]
]
let headers = [ "Content-Type": "application/json" ]
var request = URLRequest(url: urlComponent.url!)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject: param)
request.allHTTPHeaderFields = headers
//Now use this URLRequest with Alamofire to make request
Alamofire.request(request).responseJSON { response in
//Your code
}

Try this using Custom encoding
struct JSONStringArrayEncoding: ParameterEncoding {
private let array: [[String : Any]]
init(array: [[String : Any]]) {
self.array = array
}
func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
var urlRequest = try urlRequest.asURLRequest()
let data = try JSONSerialization.data(withJSONObject: array, options: [])
if urlRequest.value(forHTTPHeaderField: "Content-Type") == nil {
urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
}
urlRequest.httpBody = data
return urlRequest
}
}
Call
let values = [
[
"fieldName" : "abc",
"fieldValue":"xyz"
],
[
"fieldName" : "123",
"fieldValue":"789"
]
]
let param = [
"page":"1",
"size":"5",
"sortBy":"profile_locality"
]
let parameterEncoding = JSONStringArrayEncoding.init(array: values)
Alamofire.request("url", method: .post, parameters: param, encoding:parameterEncoding ).validate().response { (responseObject) in
// do your work
}
