Php Swift-向服务器发送字典时数据格式不正确
在服务器开发期间,我使用cURL测试发布的数据。现在我在客户端开发,从服务器返回的数据似乎格式不正确 首先,我将向您展示我使用cURL发送的内容:Php Swift-向服务器发送字典时数据格式不正确,php,swift,curl,nsurlsession,nsurlsessiondatatask,Php,Swift,Curl,Nsurlsession,Nsurlsessiondatatask,在服务器开发期间,我使用cURL测试发布的数据。现在我在客户端开发,从服务器返回的数据似乎格式不正确 首先,我将向您展示我使用cURL发送的内容: curl -X PUT --data "requests[0][data_dictionary][primary_email_address]=myemail@domain.com&requests[0][data_dictionary][first_name]=First&requests[0][data_dictionary][s
curl -X PUT --data "requests[0][data_dictionary][primary_email_address]=myemail@domain.com&requests[0][data_dictionary][first_name]=First&requests[0][data_dictionary][surname]=Last&requests[0][data_dictionary][password]=mypassword" -k -L https://localhost/rest/v1/account/create
当我打印出收到的数据时,我得到以下信息:
Request dictionaries: Array
(
[0] => Array
(
[data_dictionary] => Array
(
[primary_email_address] => myemail@domain.com
[first_name] => First
[surname] => Last
[password] => mypassword
)
)
)
这就是我所期望的。现在,客户端:
以下是使用NSJSONSerialization类向NSData上交之前的字典:
下面是服务器的响应:
Request dictionaries: Array
(
[{
__"requests"_:_] => Array
(
[
{
"data_dictionary" : {
"first_name" : "First",
"primary_email_address" : "myemail@domain.com",
"surname" : "Last",
"password" : "mypassword"
}
}
] =>
)
)
然后,当我尝试访问密钥“请求”时,服务器自然会回复一个未定义的偏移量错误
下面是将数据发送到服务器的函数。注意,我也检查了HTTP方法,它按预期“放置”:
public func fetchResponses(completionHandler: FetchResponsesCompletionHandler)
{
let session = NSURLSession(configuration: NSURLSessionConfiguration.defaultSessionConfiguration(),
delegate: self,
delegateQueue: nil)
let request = NSMutableURLRequest(URL: requestConfiguration.restURI)
request.HTTPMethod = requestConfiguration.httpMethod
if (requestConfiguration.postDictionary != nil)
{
print("Dictionary to be posted: \(requestConfiguration.postDictionary!)")
// Turn the dictionary in to a JSON NSData object
let jsonData: NSData
do
{
jsonData = try NSJSONSerialization.dataWithJSONObject(requestConfiguration.postDictionary!, options: [.PrettyPrinted])
}
catch let jsonError as NSError
{
fatalError("JSON error when encoding request data: \(jsonError)")
}
// Set HTTP Body with the post dictionary's data
request.HTTPBody = jsonData
// Set HTTP headers
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.setValue("application/json", forHTTPHeaderField: "Accept")
request.setValue("\(request.HTTPBody!.length)", forHTTPHeaderField: "Content-Length")
}
let task = session.dataTaskWithRequest(request) { (data, response, error) in
// Check return values
if error != nil
{
fatalError("Request error: \(error)")
}
// Get JSON data
let jsonDictionary: NSDictionary
do {
jsonDictionary = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as! NSDictionary
}
catch let jsonError as NSError
{
let responseAsString = NSString(data: data!, encoding: NSUTF8StringEncoding)!
print("Server return data as string: \(responseAsString)")
fatalError("JSON Error when decoding response data: \(jsonError)")
}
// Do some stuff with the data
// Complete with the client responses
completionHandler(error: nil, responses: clientResponses)
}
task.resume()
}
另外值得注意的是,我的代码目前没有显示在这里,并且成功地跳过了服务器证书的身份验证。好的,因此事实证明我正在发送一个JSON对象,而我的服务器需要一个参数字符串。它们是不同的东西。为了解决这个问题,我需要使用json_decode file_get_contents'php://input,以便将json对象作为关联数组获取
