NSURLSession을 사용하여 POST 요청 전송
업데이트: 솔루션을 찾았습니다.투고 마지막에 읽으실 수 있습니다.
리모트 REST API에 대한 POST 요청을 실행하려고 합니다.NSURLSession다음 두 가지 파라미터를 사용하여 요청을 작성하는 것이 좋습니다.deviceId그리고.textContent.
문제는 이러한 파라미터가 서버에 의해 인식되지 않는다는 것입니다.POSTMAN for Google Chrome을 사용하여 POST를 보냈기 때문에 서버 부분은 정상적으로 동작합니다.
현재 사용하고 있는 코드는 다음과 같습니다.
NSString *deviceID = [[NSUserDefaults standardUserDefaults] objectForKey:@"deviceID"];
NSString *textContent = @"New note";
NSString *noteDataString = [NSString stringWithFormat:@"deviceId=%@&textContent=%@", deviceID, textContent];
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = @{
@"api-key" : @"API_KEY",
@"Content-Type" : @"application/json"
};
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
NSURL *url = [NSURL URLWithString:@"http://url_to_manage_post_requests"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPBody = [noteDataString dataUsingEncoding:NSUTF8StringEncoding];
request.HTTPMethod = @"POST";
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
// The server answers with an error because it doesn't receive the params
}];
[postDataTask resume];
저도 같은 시술을 해봤어요NSURLSessionUploadTask:
// ...
NSURL *url = [NSURL URLWithString:@"http://url_to_manage_post_requests"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPMethod = @"POST";
NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:request fromData:[noteDataString dataUsingEncoding:NSUTF8StringEncoding] completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
// The server answers with an error because it doesn't receive the params
}];
[uploadTask resume];
좋은 생각 있어요?
솔루션
내 접근 방식의 문제는 내가 잘못된 정보를 보낸다는 것이다.Content-Type헤더를 작성했습니다.따라서 코드가 올바르게 동작하기 위해 필요한 변경은 다음 명령어를 삭제하는 것 뿐입니다.Content-Type = application/jsonHTTP 헤더따라서 올바른 코드는 다음과 같습니다.
NSString *deviceID = [[NSUserDefaults standardUserDefaults] objectForKey:@"deviceID"];
NSString *textContent = @"New note";
NSString *noteDataString = [NSString stringWithFormat:@"deviceId=%@&textContent=%@", deviceID, textContent];
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = @{
@"api-key" : @"API_KEY"
};
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
NSURL *url = [NSURL URLWithString:@"http://url_to_manage_post_requests"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPBody = [noteDataString dataUsingEncoding:NSUTF8StringEncoding];
request.HTTPMethod = @"POST";
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
// The server answers with an error because it doesn't receive the params
}];
[postDataTask resume];
다른 파라미터와 함께 영상 전송
이미지를 다른 파라미터와 함께 게시해야 하는 경우NSURLSession예를 들어 다음과 같습니다.
NSString *deviceID = [[NSUserDefaults standardUserDefaults] objectForKey:@"deviceID"];
NSString *textContent = @"This is a new note";
// Build the request body
NSString *boundary = @"SportuondoFormBoundary";
NSMutableData *body = [NSMutableData data];
// Body part for "deviceId" parameter. This is a string.
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", @"deviceId"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"%@\r\n", deviceID] dataUsingEncoding:NSUTF8StringEncoding]];
// Body part for "textContent" parameter. This is a string.
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", @"textContent"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"%@\r\n", textContent] dataUsingEncoding:NSUTF8StringEncoding]];
// Body part for the attachament. This is an image.
NSData *imageData = UIImageJPEGRepresentation([UIImage imageNamed:@"ranking"], 0.6);
if (imageData) {
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", @"image"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:imageData];
[body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// Setup the session
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = @{
@"api-key" : @"55e76dc4bbae25b066cb",
@"Accept" : @"application/json",
@"Content-Type" : [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary]
};
// Create the session
// We can use the delegate to track upload progress
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration delegate:self delegateQueue:nil];
// Data uploading task. We could use NSURLSessionUploadTask instead of NSURLSessionDataTask if we needed to support uploads in the background
NSURL *url = [NSURL URLWithString:@"URL_TO_UPLOAD_TO"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPMethod = @"POST";
request.HTTPBody = body;
NSURLSessionDataTask *uploadTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
// Process the response
}];
[uploadTask resume];
매개 변수에 NSDictionary를 사용해 볼 수 있습니다.다음에 의해 파라미터가 JSON 서버로 올바르게 송신됩니다.
NSError *error;
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURL *url = [NSURL URLWithString:@"[JSON SERVER"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
[request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request addValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setHTTPMethod:@"POST"];
NSDictionary *mapData = [[NSDictionary alloc] initWithObjectsAndKeys: @"TEST IOS", @"name",
@"IOS TYPE", @"typemap",
nil];
NSData *postData = [NSJSONSerialization dataWithJSONObject:mapData options:0 error:&error];
[request setHTTPBody:postData];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
}];
[postDataTask resume];
(상기의 CSRF 인증 문제를 정렬하려고 하는데 NSDictionary에 파라미터가 송신됩니다).

솔루션
고객의 요건에 따라서는, 1개의 간단한 솔루션이,String대신Dictionary로 변환합니다.Data아래 코드 샘플이 작성되어 있습니다.Objective-C그리고.Swift 3.0.
목표-C
// Create the URLSession on the default configuration
NSURLSessionConfiguration *defaultSessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration:defaultSessionConfiguration];
// Setup the request with URL
NSURL *url = [NSURL URLWithString:@"yourURL"];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];
// Convert POST string parameters to data using UTF8 Encoding
NSString *postParams = @"api_key=APIKEY&email=example@example.com&password=password";
NSData *postData = [postParams dataUsingEncoding:NSUTF8StringEncoding];
// Convert POST string parameters to data using UTF8 Encoding
[urlRequest setHTTPMethod:@"POST"];
[urlRequest setHTTPBody:postData];
// Create dataTask
NSURLSessionDataTask *dataTask = [defaultSession dataTaskWithRequest:urlRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
// Handle your response here
}];
// Fire the request
[dataTask resume];
재빠르다
// Create the URLSession on the default configuration
let defaultSessionConfiguration = URLSessionConfiguration.default
let defaultSession = URLSession(configuration: defaultSessionConfiguration)
// Setup the request with URL
let url = URL(string: "yourURL")
var urlRequest = URLRequest(url: url!) // Note: This is a demo, that's why I use implicitly unwrapped optional
// Convert POST string parameters to data using UTF8 Encoding
let postParams = "api_key=APIKEY&email=example@example.com&password=password"
let postData = postParams.data(using: .utf8)
// Set the httpMethod and assign httpBody
urlRequest.httpMethod = "POST"
urlRequest.httpBody = postData
// Create dataTask
let dataTask = defaultSession.dataTask(with: urlRequest) { (data, response, error) in
// Handle your response here
}
// Fire the request
dataTask.resume()
https://github.com/mxcl/OMGHTTPURLRQ 를 사용할 수 있습니다.
id config = [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:someID];
id session = [NSURLSession sessionWithConfiguration:config delegate:someObject delegateQueue:[NSOperationQueue new]];
OMGMultipartFormData *multipartFormData = [OMGMultipartFormData new];
[multipartFormData addFile:data1 parameterName:@"file1" filename:@"myimage1.png" contentType:@"image/png"];
NSURLRequest *rq = [OMGHTTPURLRQ POST:url:multipartFormData];
id path = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:@"upload.NSData"];
[rq.HTTPBody writeToFile:path atomically:YES];
[[session uploadTaskWithRequest:rq fromFile:[NSURL fileURLWithPath:path]] resume];
Swift 2.0 솔루션은 다음과 같습니다.
let urlStr = “http://url_to_manage_post_requests”
let url = NSURL(string: urlStr)
let request: NSMutableURLRequest =
NSMutableURLRequest(URL: url!) request.HTTPMethod = "POST"
request.setValue(“application/json” forHTTPHeaderField:”Content-Type”)
request.timeoutInterval = 60.0
//additional headers
request.setValue(“deviceIDValue”, forHTTPHeaderField:”DeviceId”)
let bodyStr = “string or data to add to body of request”
let bodyData = bodyStr.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
request.HTTPBody = bodyData
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(request){
(data: NSData?, response: NSURLResponse?, error: NSError?) -> Void in
if let httpResponse = response as? NSHTTPURLResponse {
print("responseCode \(httpResponse.statusCode)")
}
if error != nil {
// You can handle error response here
print("\(error)")
}else {
//Converting response to collection formate (array or dictionary)
do{
let jsonResult: AnyObject = (try NSJSONSerialization.JSONObjectWithData(data!, options:
NSJSONReadingOptions.MutableContainers))
//success code
}catch{
//failure code
}
}
}
task.resume()
Swift를 사용하는 경우 Just 라이브러리가 이 기능을 제공합니다.readme 파일의 예:
// talk to registration end point
Just.post(
"http://justiceleauge.org/member/register",
data: ["username": "barryallen", "password":"ReverseF1ashSucks"],
files: ["profile_photo": .URL(fileURLWithPath:"flash.jpeg", nil)]
) { (r)
if (r.ok) { /* success! */ }
}
Teja Kumar Bethina의 코드가 Swift 3으로 변경되었습니다.
let urlStr = "http://url_to_manage_post_requests"
let url = URL(string: urlStr)
var request: URLRequest = URLRequest(url: url!)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField:"Content-Type")
request.timeoutInterval = 60.0
//additional headers
request.setValue("deviceIDValue", forHTTPHeaderField:"DeviceId")
let bodyStr = "string or data to add to body of request"
let bodyData = bodyStr.data(using: String.Encoding.utf8, allowLossyConversion: true)
request.httpBody = bodyData
let task = URLSession.shared.dataTask(with: request) {
(data: Data?, response: URLResponse?, error: Error?) -> Void in
if let httpResponse = response as? HTTPURLResponse {
print("responseCode \(httpResponse.statusCode)")
}
if error != nil {
// You can handle error response here
print("\(error)")
} else {
//Converting response to collection formate (array or dictionary)
do {
let jsonResult = (try JSONSerialization.jsonObject(with: data!, options:
JSONSerialization.ReadingOptions.mutableContainers))
//success code
} catch {
//failure code
}
}
}
task.resume()
