How to write GraphQL Query - swift

Question

I have a working web graphql query as :
{
me{
... on Student{
profile {
fullName
emailId
mobileNumber
civilId
address
city
state
country
zipCode
userProfilePic
userCategory
createdAt
updatedAt
}
}
}
}
It returns the profile details of a particular student. I log using mutation and gets the token for a user.
I want to create a graphql file (ex. StudentProfile.graphql) in order to make fetch request (similar to http. get) using Apollo client.
I make this request to fetch the graphql query.
func fetchStudentProfileDetails(){
let tokenString = "Bearer " + "....my token ..."
print(tokenString)
let newApollo: ApolloClient = {
let configuration = URLSessionConfiguration.default
// Add additional headers as needed
configuration.httpAdditionalHeaders = ["Authorization": tokenString]
let url = URL(string: "http://52.88.217.19/graphql")!
return ApolloClient(networkTransport: HTTPNetworkTransport(url: url, configuration: configuration))
}()
newApollo.fetch(query: StudentProfileQuery()) { (result, error) in
self.profileDetailsTextView.text = "Success"
if let error = error {
NSLog("Error while fetching query: \(error.localizedDescription)");
self.profileDetailsTextView.text = error.localizedDescription
}
guard let result = result else {
NSLog("No query result");
self.profileDetailsTextView.text = "No query result"
return
}
if let errors = result.errors {
NSLog("Errors in query result: \(errors)")
self.profileDetailsTextView.text = String(describing: errors)
}
guard let data = result.data else {
NSLog("No query result data");
return
}
}
}
How do I convert the following web query into a query in the .graphql file?

Answer 1

so, you can call to create new document into Graphql server using a simple NSUrlSession
let headers = ["content-type": "application/json"]
let parameters = ["query": "mutation { createProfile(fullName: \"test name\" emailId: \"test#email.com\") { id } }"] as [String : Any]
let postData = JSONSerialization.data(withJSONObject: parameters, options: [])
let request = NSMutableURLRequest(url: NSURL(string: "https://<url graphql>")! as URL, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 10.0)
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers
request.httpBody = postData as Data
let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
if (error != nil) {
print(error)
} else {
let httpResponse = response as? HTTPURLResponse
print(httpResponse)
}
})
dataTask.resume()

I'm not sure I completely understand your question, but you should be able to use HTTP to make queries. For most people, a *.gql file just contains the query as a String which they URLEncode. Below is an example of reading from a variable but you could do just the same reading the query from a file as a string/buffer.
const myQuery = `{
user {
name
}
}`;
const queryURL = "http://52.88.217.19/graphql/?query=" + URLEncode(myQuery);
fetch(queryURL)
.then((result) => {
console.log(result);
})
If this does not answer your question, please help me better understand what you are asking, and I will try to revise my answer.
