I am trying to post some data to the API, but I keep getting Response status code was unacceptable: 404 error message.. I have checked, the POST parameters and API Url are all correct, example request works on the postman but it is not working on Xcode..
my POST request Url is in this format: {{API}}/postData/Id/block.
my POST request function with Alamofire is as follows:
func postData(token: String, id: String, category: String, completion: #escaping(_ data: DataTobePost) -> Void) {
let header: HTTPHeaders = ["authorization": token]
let parameter: Parameters = [
"Id": id,
"category": category ]
Alamofire.request(API_Configurator.postData, method: .post, parameters: parameter, encoding: JSONEncoding.default, headers: header).validate().responseData(completionHandler: { response in
switch response.result {
case .success(let val):
do {
let data = try JSONDecoder().decode(DataTobePost.self, from: val)
completion(data)
}catch {
print("[DataTobePost Catch Error while decoding response: \(error.localizedDescription)]")
}
case .failure(let error):
print("[DataTobePost Failure Error : \(error.localizedDescription)]")
}
})
}
and the response is:
{
"success": true
}
where am i going wrong, can anyone help through this. (I am quite new to Alamofire)
There is no way to check what is wrong.
If you got the 404 error it means 2 things:
Code was written correctly(it compiles)
Requested page does not exist (404 error)
I think you need to check your API_Configurator.postData.
Usually, it's something simple like extra characters like "//", " ", "." etc.
Or the problem with API.
The best way to check API uses Postman
Hello I am trying to use Alamofire for my HTTP requests. It is working with parameters that are not included any nested parameter. Normally, my url is working with following on the Google Chrome.
http://111.222.33.4:12345/my_server/dispatch?cmd=ext_getReferanceData&jp=%7b%22rfName%22:%22RF_ABC%22%7d&token=123
and the decoded version of above url is
http://111.222.33.4:12345/my_server/dispatch?cmd=ext_getReferanceData&jp={"rfName":"RF_ABC"}&token=123
It works fine when I paste it into any browser. However when I try to send following post request with Alamofire
let parameters3: [String: Any] = [
"cmd": "ext_getReferanceData",
"jp": [
"rfName": "RF_ABC"
],
"token": "123"
]
Alamofire.request("http://111.222.33.4:12345/my_server/dispatch", method: .get, parameters: parameters3, encoding: JSONEncoding.default).responseJSON { (response) in
}
It is returning
FAILURE:
responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength)
What could be the reason of it am I sending parameters wrong or is there anything that I am missing?
Edit: I also checked other questions about the error but the problem is about parameters that I am trying to send because there is " and { in the parameters but I could not send in the request.
have you considered printing the response being sent and confirming it that it's indeed the stuff you're trying to send?
You can do a couple of things to improve
Make the method .post
Try to use .validate() for added reliability
The way I do it is something like:
let submissionURL = URL(string: "https://blablabla.com/script.php")
sendAlamofireRequest(submissionURL: submissionURL!, parameters: parameters, chosenTrackerStr: chosenTrackerString) //function call
//function declaration
func sendAlamofireRequest(submissionURL: URL, parameters: Parameters, chosenTrackerStr: String){
Alamofire.request(submissionURL, method: .post, parameters: parameters, encoding: JSONEncoding.default).validate().responseString() { (response) in
//actual code goes here
}
}
Maybe try to play around with the alamofire request and check its documentation to see the suggested approach :)
I'm trying to re-create this Postman settings for posting in Alamofire. This is my first time to see an API that requires both Parameters and a body with Raw Json.
I'm done with gathering and formatting my data (either in Json using SwiftyJSON or Dictionary [String : Any] / Parameters) for the said requirement.
While I did see a similar question to this: Postman request to Alamofire request but it doesn't have a valid answer. Assume that I'm quite experienced with posting/getting/etc data from various API but I just don't know how to pass raw data just like in the photo above. Please check out my comments too in the code.
Here's what I'm doing with my function for this request:
/** Apply to job with Shift.
* This service function creates a json data for applying.
*/
func someFuncService(_ job: Job, daySchedules: [(Int, String, Schedule)], withBlock completion: #escaping JobServiceCommonCallBack) {
AuthService.someFunc { (currentCustomer, accessToken) in
guard let lalala = currentCustomer?.id,
let accessT = accessToken else {
completion(LalaErrors.currentCustomerError)
return
}
guard let jobId = job.id else {
completion(LalaErrors.modelError)
return
}
let coreService = LalaCoreService()
let applicantEndpoint = LalaCoreService.Endpoint.Applicant
let parameters = [
"param1" : customerId,
"param2" : jobId,
"accessToken" : accessToken,
"shift" : self.generateDataFromDaySchedules(daySchedules) // this returns [String : Any], can be printed into Json using JSON(x)
] as Parameters
GPLog(classSender: self, log: "FINAL PARAMETER: \(parameters)")
coreService.request = Alamofire.request(
applicantEndpoint,
method: .post,
parameters: parameters,
encoding: URLEncoding.default, // I already have tried .httpbody too.
headers: nil
)
coreService.request {
(response, result) in
if let error = result?.error {
if response!.statusCode == 500 {
completion(GPKitError.newError(description: "Failed to apply. Please contact the admin."))
return
}
completion(error)
return
}
// Success
completion(nil)
return
}
}
}
EDIT: So the question is, what I'm doing wrong here? API returns me status code 500 internal server error.
coreService.request = Alamofire.request(
applicantEndpoint,
method: .post,
parameters: parameters,
encoding: URLEncoding.default, // I already have tried .httpbody too.
headers: nil
)
should be
coreService.request = Alamofire.request(
applicantEndpoint + accessToken,
method: .post,
parameters: parameters,
encoding: JSONEncoding.default,
headers: nil
)
I am trying to make a JSON Request with Alamofire but the response is in Greek and Swift returns:
Response
{
id = 4;
name = "\U0395\U03bb\U03b1\U03b9\U03cc\U03bb\U03b1\U03b4\U03bf"
url = "http://www.gaiaskarpos.com/app/images/categories/olive.png";
}
The problem is at name field.
//Swift Alamofire Request
Alamofire.request(.GET, "http://gaiaskarpos.com/applegetCategores.php",
encoding:.JSON).validate().responseJSON{(response)->
Void in print("Response Json : \(response.result.value)")
I had a same issue in Arabic/Persian chars and It's my solution:
json variable :
{
message = "\U062f\U0633\U062a\U06af\U0627\U0647 \U0645\U0639\U062a\U0628\U0631 \U0646\U06cc\U0633\U062a";
status = 0;
}
So I casted json to [String: AnyObject] :
var test = json as? [String : AnyObject]
print(test)
It's fixed. You should give it a try.
Why is your encoding .JSON? You send .GET-request and you don't need to specify the type of encoding in your request.
Alamofire documentation say:
Alamofire.request(.GET, "https://httpbin.org/get", parameters: ["foo": "bar"])
.responseJSON { response in
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization
if let JSON = response.result.value {
print("JSON: \(JSON)")
}
}
So use it. Links -> http://cocoadocs.org/docsets/Alamofire/1.1.3/ and https://github.com/Alamofire/Alamofire
You must specify the type of encoding when you pass parameters in the body of your request. It is for .POST and .PUT requests.
Try to print 'name' to Debug area. Maybe you'll get name in normal encoding... Xcode has the disadvantage: it shows not-UTF8 data in response like '\U0395\U03bb ... ... ... \U03b1\U03b9\' when there is some level of nested data in response.
Try to use NSUTF8StringEncoding with alamofire response
encoding: NSUTF8StringEncoding
Try to serialize the JSON with below code this might help you
let dict = NSJSONSerialization.JSONObjectWithData(jsonString.dataUsingEncoding(NSUTF8StringEncoding)!,
options: nil, error: nil) as [String : String]
Alamofire.request(.GET, "url").authenticate(user: "", password: "").responseJSON() {
(request, response, json, error) in
println(error)
println(json)
}
This is my request with Alamofire, for a certain request it sometime works, but sometimes i get:
Optional(Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (Invalid value around character 0.) UserInfo=0x78e74b80 {NSDebugDescription=Invalid value around character 0.})
I've read that this can be due to invalid JSON, but the response is a static json string that i have validated in JSON validator as valid. It does contain å ä ö characters and some HTML.
Why am i getting this error sometimes?
I also faced same issue. I tried responseString instead of responseJSON and it worked. I guess this is a bug in Alamofire with using it with django.
In my case , my server URL was incorrect. Check your server URL !!
I got same error while uploading image in multipart form in Alamofire as i was using
multipartFormData.appendBodyPart(data: image1Data, name: "file")
i fixed by replacing by
multipartFormData.appendBodyPart(data: image1Data, name: "file", fileName: "myImage.png", mimeType: "image/png")
Hope this help someone.
May this Help YOu
Alamofire.request(.GET, "YOUR_URL")
.validate()
.responseString { response in
print("Success: \(response.result.isSuccess)")
print("Response String: \(response.result.value)")
}
The same issue happened to me and it actually ended up being a server issue since the content type wasn't set.
Adding
.validate(contentType: ["application/json"])
To the request chain solved it for me
Alamofire.request(.GET, "url")
.validate(contentType: ["application/json"])
.authenticate(user: "", password: "")
.responseJSON() { response in
switch response.result {
case .Success:
print("It worked!")
print(response.result.value)
case .Failure(let error):
print(error)
}
}
I got the same error. But i found the solution for it.
NOTE 1: "It is not Alarmofire error", it's bcouse of server error.
NOTE 2: You don't need to change "responseJSON" to "responseString".
public func fetchDataFromServerUsingXWWWFormUrlencoded(parameter:NSDictionary, completionHandler: #escaping (_ result:NSDictionary) -> Void) -> Void {
let headers = ["Content-Type": "application/x-www-form-urlencoded"]
let completeURL = "http://the_complete_url_here"
Alamofire.request(completeURL, method: .post, parameters: (parameter as! Parameters), encoding: URLEncoding.default, headers: headers).responseJSON { response in
if let JSON = response.result.value {
print("JSON: \(JSON)") // your JSONResponse result
completionHandler(JSON as! NSDictionary)
}
else {
print(response.result.error!)
}
}
}
This is how I managed to resolve the Invalid 3840 Err.
The error log
responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0." UserInfo={NSDebugDescription=Invalid value around character 0.}))
It was with Encoding Type used in the Request, The Encoding Type used should be acceptedin your Server-Side.
In-order to know the Encoding I had to run through all the Encoding Types:
default/
methodDependent/
queryString/
httpBody
let headers: HTTPHeaders = [
"Authorization": "Info XXX",
"Accept": "application/json",
"Content-Type" :"application/json"
]
let parameters:Parameters = [
"items": [
"item1" : value,
"item2": value,
"item3" : value
]
]
Alamofire.request("URL",method: .post, parameters: parameters,encoding:URLEncoding.queryString, headers: headers).responseJSON { response in
debugPrint(response)
}
It also depends upon the response we are recieving use the appropriate
responseString
responseJSON
responseData
If the response is not a JSON & just string in response use responseString
Example: in-case of login/ create token API :
"20dsoqs0287349y4ka85u6f24gmr6pah"
responseString
I solved using this as header:
let header = ["Content-Type": "application/json",
"accept": "application/json"]
In my case, there was an extra / in the URL .
Maybe it is too late but I solved this problem in another way not mentioned here:
When you use .responseJSON(), you must set the response header with content-type = application/json, if not, it'll crash even if your body is a valid JSON. So, maybe your response header are empty or using another content-type.
Make sure your response header is set with content-type = application/json to .responseJSON() in Alamofire work properly.
Hey guys this is what I found to be my issue: I was calling Alamofire via a function to Authenticate Users: I used the function "Login User" With the parameters that would be called from the "body"(email: String, password: String) That would be passed
my errr was exactly:
optional(alamofire.aferror.responseserializationfailed(alamofire.aferror.responseserializationfailurereason.jsonserializationfailed(error domain=nscocoaerrordomain code=3840 "invalid value around character 0." userinfo={nsdebugdescription=invalid value around character 0
character 0 is the key here: meaning the the call for the "email" was not matching the parameters: See the code below
func loginUser(email: String, password: String, completed: #escaping downloadComplete) {
let lowerCasedEmail = email.lowercased()
let header = [
"Content-Type" : "application/json; charset=utf-8"
]
let body: [String: Any] = [
"email": lowerCasedEmail,
"password": password
]
Alamofire.request(LOGIN_USER, method: .post, parameters: body, encoding: JSONEncoding.default, headers: header).responseJSON { (response) in
if response.result.error == nil {
if let data = response.result.value as? Dictionary<String, AnyObject> {
if let email = data["user"] as? String {
self.userEmail = email
print(self.userEmail)
}
if let token = data["token"] as? String {
self.token_Key = token
print(self.token_Key)
}
"email" in function parameters must match the let "email" when parsing then it will work..I no longer got the error...And character 0 was the "email" in the "body" parameter for the Alamofire request:
Hope this helps
I was sending the improper type (String) to the server in my parameters (needed to be an Int).
Error was resolved after adding encoding: JSONEncoding.default with Alamofire.
Alamofire.request(urlString, method: .post, parameters:
parameters,encoding:
JSONEncoding.default, headers: nil).responseJSON {
response in
switch response.result {
case .success:
print(response)
break
case .failure(let error):
print(error)
}
}
The application I was working on this morning had the same error. I believed it to be a server side error since I was unable to upload a user image.
However, upon checking my custom API, I realized that after adding an SSL certificate to my website that I had not updated the api.swift URLs, the data was unable to post:
let HOME_URL = "http://sitename.io"
let BASE_URL = "http://sitename.io/api"
let UPLOAD_URL = "http://sitename.io/api/user/upload"
I changed the URL's to https://. Problem solved.
In my case I have to add this Key: "Accept":"application/json" to my header request.
Something like this:
let Auth_header: [String:String] = ["Accept":"application/json", "Content-Type" : "application/json", "Authorization":"Bearer MyToken"]
I hope that this can help someone.
I face same issue and problem is in params.
let params = [kService: service,
kUserPath: companyModal.directory_path,
kCompanyDomain: UserDefaults.companyDomain,
kImageObject: imageString,
kEntryArray: jsonString,
kUserToken: UserDefaults.authToken] as [String : Any]
companyModal.directory_path is url. it coerced from string to any which create issues at server side. To resolve this issue I have to give default value which make it string value.
let params = [kService: kGetSingleEntry,
kUserPath: companyModal.directory_path ?? "",
kCompanyDomain: UserDefaults.companyDomain,
kUserToken: UserDefaults.authToken,
kEntryId: id,
] as [String: Any]
Probably you have "/" at the end of your path. If it is not GET request, you shouldn't put "/" at the end, otherwise you'll get the error
I Changed mimeType from "mov" to "multipart/form-data".
Alamofire.upload(multipartFormData: { (multipartFormData) in
do {
let data = try Data(contentsOf: videoUrl, options: .mappedIfSafe)
let fileName = String(format: "ios-video_%#.mov ", profileID)
multipartFormData.append(data, withName: "video", fileName: fileName, mimeType: "multipart/form-data")
} catch {
completion("Error")
}
}, usingThreshold: .init(), to: url,
method: .put,
headers: header)
Worked for me.. :)
For my case:
let header = ["Authorization": "Bearer \(Authserices.instance.tokenid)"]
I forgot the space before \ (after Bearer)
In my case error was due to duplicate email. You can recheck your API on postman to see if response there is OK or not.
In my case, I tried using Postman to get API and this error come from backend.
