我有一个对API的请求,该API应该发布一些json:
class func makeAPICall (serializedJSONObject contentMap: Dictionary<String, String>, completion: ((data: NSData?, response: NSURLResponse?, error: NSError?) -> Void)) throws -> Void {
var jsonData: NSData
do {
jsonData = try NSJSONSerialization.dataWithJSONObject(contentMap, options: NSJSONWritingOptions())
var jsonString = NSString(data: jsonData, encoding: NSUTF8StringEncoding) as! String
print(jsonString)
jsonString = jsonString.stringByAddingPercentEncodingForFormUrlencoded()!
print(jsonString)
jsonData = jsonString.dataUsingEncoding(NSUTF8StringEncoding)!
let postsEndpoint: String = "https://www.example.com/api/v2"
guard let postsURL = NSURL(string: postsEndpoint) else {
throw APICallError.other("cannot create URL")
}
let postsURLRequest = NSMutableURLRequest(URL: postsURL)
print(jsonData)
postsURLRequest.HTTPBody = jsonData
print(postsURLRequest)
postsURLRequest.HTTPMethod = "POST"
let config = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration: config)
let task = session.dataTaskWithRequest(postsURLRequest, completionHandler: {
(data, response, error) in
completion(data: data, response: response, error: error)
})
task.resume() //starts the request. It's called resume() because a session starts in a suspended state
} catch {
print("lol, problem")
}
}
带有扩展名(用于
x-www-form-urlencoded
编码):extension String {
func stringByAddingPercentEncodingForFormUrlencoded() -> String? {
let characterSet = NSMutableCharacterSet.alphanumericCharacterSet()
characterSet.addCharactersInString("-._* ")
return stringByAddingPercentEncodingWithAllowedCharacters(characterSet)?.stringByReplacingOccurrencesOfString(" ", withString: "+")
}
}
现在我也有这个简单的测试页面来测试json请求:
<form action="v2/" method="post">
<textarea name="data" rows="20" cols="80"></textarea>
<input type="submit" />
</form>
服务器记录了所有请求,因此我发现我的应用实际上使用的是GET而不是POST
应用程序请求日志:

最佳答案
您可以先尝试一下吗?
if let postEndpoint: NSURL = NSURL(string: "https://www.example.com/api/v2") {
let postURLRequest: NSMutableURLRequest = NSMutableURLRequest(URL: postEndpoint)
postURLRequest.HTTPMethod = "POST"
postURLRequest.HTTPBody = UTF8EncodedJSON
NSURLSession.sharedSession().dataTaskWithRequest(postURLRequest, completionHandler: { (data: NSData?, response: NSURLResponse?, error: NSError?) -> Void in
}).resume()
}
关于swift - NSMutableURLRequest.HTTPMethod未设置正确的方法,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/34707791/
