如何在swift iOS中使用post方法使用表单数据调用Rest Api？
我希望类似的Swift代码使用“Post”方法使用已形成的数据命中Rest Api：
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSString *encodedUrl = [[NSString stringWithFormat:@"%@%@", self.BaseUrl, strMethodName]stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
NSURL *serverUrl = [NSURL URLWithString:encodedUrl];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:serverUrl cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSError *error = nil;
NSMutableString *body = [NSMutableString string];
for (NSString *key in requestDict) {
NSString *val = [requestDict objectForKey:key];
if ([body length]){
[body appendString:@"&"];
}
[body appendFormat:@"%s=%s", [[key description] UTF8String], [[val description] UTF8String]];
}
NSMutableData *postData = (NSMutableData *)[body dataUsingEncoding:NSUTF8StringEncoding];
NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[postData length]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
// [request setValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:@"Content-Type"];
func simplePostMethod() {
let url : URL = URL(string: "write your URL")!
var request = URLRequest(url: url)
let session = URLSession.shared
request.httpMethod = "POST"
// this is your input parameter dictionary
let params = ["name":"Rizwan", "nickname":"Shaikh","password":"123456","gender":"male","dob":"1989-02-28","email":"[email protected]","device_id":"sffdg5645445","os":"ios"] as Dictionary<String, String>
do{
request.httpBody = try JSONSerialization.data(withJSONObject: params, options: JSONSerialization.WritingOptions.prettyPrinted)
}
catch
{
// catch any exception here
}
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
let task = session.dataTask(with: request, completionHandler: {(data,response,error) in
if (data != nil)
{
do{
let dict = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableLeaves)
print(dict);
}
catch
{
// catch any exception here
}
}
}
)
task.resume()
}
尝试使用AFNetworking，非常容易使用。
let body = { () -> Data! in
do {
if let fname = user.firstName, let lname = user.lastName, let email = user.email
{
let params : [String : Any] = ["firstname" : fname, "lastname" : lname, "email":email]
return try JSONSerialization.data(withJSONObject: params, options: .prettyPrinted)
}
} catch {
print(error)
}
return nil
}()
var request = URLRequest(url: URL(string:url)!)
request.httpMethod = "POST"
request.httpBody = body!
let session = URLSession.shared
let dataTask = session.dataTask(with: request) {data,response,error in
let httpResponse = response as? HTTPURLResponse
if (error != nil) {
print(error)
} else {
print(httpResponse)
}
DispatchQueue.main.async {
//Update your UI here
}
}
dataTask.resume()
