POST application / x-www-form-urlencodedを使用したリクエスト

バックエンドの開発者は、POSTリクエストにこれらの指示を与えていました。

  1. ルート:{URL}/{APP_NAME/{コントローラ}/{アクション}
  2. コントローラとアクションは、スモールキャップにする必要があります。
  3. APIのテストリンクします。http:****************
  4. 要求は、使用POSTの方法でなければなりません。
  5. パラメータは、要求内容本体(FormUrlEncodedContent)を介してパスする必要があります。
  6. パラメータは、JSON形式にする必要があります。
  7. パラメータは、キー敏感です。

プロトコルで5番と何の経験を持っていない、私は検索し、私のコードで終了しました。

-(id)initWithURLString:(NSString *)URLString withHTTPMEthod:(NSString *)method withHTTPBody:(NSDictionary *)body {

    _URLString = URLString;
    HTTPMethod = method;
    HTTPBody = body;

    //set error message
    errorMessage = @"Can't connect to server at this moment. Try again later";
    errorTitle = @"Connection Error";

    return  self;
}


-(void)fireConnectionRequest {

    NSOperationQueue *mainQueue = [[NSOperationQueue alloc] init];
    [mainQueue setMaxConcurrentOperationCount:5];

    NSError *error = Nil;

    NSURL *url = [NSURL URLWithString:_URLString];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];

    NSData *sendData = [NSJSONSerialization dataWithJSONObject:HTTPBody options:NSJSONWritingPrettyPrinted error:&error];
    [request setHTTPMethod:@"POST"];

    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];

    [request setHTTPBody: sendData];
    [NSURLConnection connectionWithRequest:request delegate:self];

    NSString *jsonString = [[NSString alloc]initWithData:sendData encoding:NSUTF8StringEncoding];


    //fire URL connectiion request
    [NSURLConnection sendAsynchronousRequest:request queue:mainQueue completionHandler:^(NSURLResponse *response, NSData *responseData, NSError *error) {

        //get the return message and transform to dictionary
        NSString *data = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
        returnMessage = [NSJSONSerialization JSONObjectWithData: [data dataUsingEncoding:NSUTF8StringEncoding]
                                                        options: NSJSONReadingMutableContainers
                                                          error:&error];


        //check return message
        if (!error) {
            [delegate returnMessageForTag:self.tag];

        }
        else {
            [delegate returnErrorMessageForTag:self.tag];
        }

    }];

}

私は、JSONにフォーマットされた辞書を渡します。彼は私が右のデータを渡すことができたことに同意します。また、APIに接続できましたが、登録用のデータを送信しようとすると常に「FAILED」が返されます。そこの接続に問題はありませんが、私はデータを転送することができませんでした。

ここで同じAPIを使用しているAndroid開発者は問題ありませんが、iOSに慣れていないので私を助けられませんでした。

私は何が欠けていますか?

直接あなたの答えをコメントするには十分ではない評判ため、この答え。

Swift 1.2

let myParams = "username=user1&password=12345"
let postData = myParams.dataUsingEncoding(NSASCIIStringEncoding, allowLossyConversion: true)
let postLength = String(format: "%d", postData!.length)

var myRequest = NSMutableURLRequest(URL: self.url)
myRequest.HTTPMethod = "POST"
myRequest.setValue(postLength, forHTTPHeaderField: "Content-Length")
myRequest.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
myRequest.HTTPBody = postData

var response: AutoreleasingUnsafeMutablePointer<NSURLResponse?> = nil

私の場合、上記のコードは正常に機能します。

Swift 3、let jsonData = try?JSONSerialization.data(withJSONObject:kParameters)がうまく動作しなかったため、AlamoFireソリューションをコピーする必要がありました。 ..

let body2 = ["username": "[email protected]",
        "password": "111",
        "client_secret":"7E",
        "grant_type":"password"]

let data : Data = query(body2).data(using: .utf8, allowLossyConversion: false)!
var request : URLRequest = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField:"Content-Type");
request.setValue(NSLocalizedString("lang", comment: ""), forHTTPHeaderField:"Accept-Language");
request.httpBody = data 

do {...}

}

public func queryComponents(fromKey key: String, value: Any) -> [(String, String)] {
        var components: [(String, String)] = []

        if let dictionary = value as? [String: Any] {
            for (nestedKey, value) in dictionary {
                components += queryComponents(fromKey: "\(key)[\(nestedKey)]", value: value)
            }
        } else if let array = value as? [Any] {
            for value in array {
                components += queryComponents(fromKey: "\(key)[]", value: value)
            }
        } else if let value = value as? NSNumber {
            if value.isBool {
                components.append((escape(key), escape((value.boolValue ? "1" : "0"))))
            } else {
                components.append((escape(key), escape("\(value)")))
            }
        } else if let bool = value as? Bool {
            components.append((escape(key), escape((bool ? "1" : "0"))))
        } else {
            components.append((escape(key), escape("\(value)")))
        }

        return components
    }


    public func escape(_ string: String) -> String {
        let generalDelimitersToEncode = ":#[]@" // does not include "?" or "/" due to RFC 3986 - Section 3.4
        let subDelimitersToEncode = "!$&'()*+,;="

        var allowedCharacterSet = CharacterSet.urlQueryAllowed
        allowedCharacterSet.remove(charactersIn: "\(generalDelimitersToEncode)\(subDelimitersToEncode)")

        var escaped = ""

        if #available(iOS 8.3, *) {
            escaped = string.addingPercentEncoding(withAllowedCharacters: allowedCharacterSet) ?? string
        } else {
            let batchSize = 50
            var index = string.startIndex

            while index != string.endIndex {
                let startIndex = index
                let endIndex = string.index(index, offsetBy: batchSize, limitedBy: string.endIndex) ?? string.endIndex
                let range = startIndex..<endIndex

                let substring = string.substring(with: range)

                escaped += substring.addingPercentEncoding(withAllowedCharacters: allowedCharacterSet) ?? substring

                index = endIndex
            }
        }
        return escaped
    }

そして1つの拡張機能:

extension NSNumber {
fileprivate var isBool: Bool { return CFBooleanGetTypeID() == CFGetTypeID(self) }}

これは一時的なもので、より良い解決策でなければなりません...

それが役立つことを願っています...

SwiftはURL-%-encodingの機能を提供しますが、最初のコメントで@nolanwが指摘しているように完全には一致していません。元の質問のステップ5で、何らかの構造内にキーと値のペアを取得したら、エンコード(Swift 4.2)の短くて簡単な代替方法を次に示します。

_var urlParser = URLComponents()
urlParser.queryItems = [
    URLQueryItem(name: "name", value: "Tim Tebow"),
    URLQueryItem(name: "desc", value: "Gators' QB")
]
let httpBodyString = urlParser.percentEncodedQuery
_

Xcodeの遊び場にそれを貼り付け、print(httpBodyString!)を加えます。出力には以下が表示されます。

_name=Tim%20Tebow&desc=Gators'%20QB
_

注:これは、基本的なフォームの値(すなわち、バイナリデータではなくなく、マルチパート)のパーセントコードセットのためのものである

このコードをSwift?に変換することは可能ですか?.

    let myParams:NSString = "username=user1&password=12345"
    let myParamsNSData:NSData = NSData(base64EncodedString: myParams, options: NSDataBase64DecodingOptions.IgnoreUnknownCharacters)!
    let myParamsLength:NSString = NSString(UTF8String: myParamsNSData.length)
    let myRequest: NSMutableURLRequest = NSURL(fileURLWithPath: self.url)
    myRequest.HTTPMethod = "POST"
    myRequest.addValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
    myRequest.HTTPBody = myParamsNSData
    var data2: NSData!
    var error2: NSError!

辞書パラメーターを文字列に解析します。

-(NSData *)encodeParameters:(NSDictionary *)parameters {

NSMutableArray *list = [NSMutableArray new];

for (NSString *key in [parameters allKeys]) {
    id obj = [parameters objectForKey:key];
    NSString *path = [NSString stringWithFormat:@"%@=%@", key, obj];
    [list addObject:path];
}

return [[list componentsJoinedByString:@"&"] dataUsingEncoding:NSUTF8StringEncoding];

}

そしてそれを使用します:

[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:[self encodeParameters:parameters]];

Swift 4.2

    func percentEscapeString(_ string: String) -> String {
            var characterSet = CharacterSet.alphanumerics
            characterSet.insert(charactersIn: "-._* ")
            return string
              .addingPercentEncoding(withAllowedCharacters: characterSet)!
              .replacingOccurrences(of: " ", with: " ")
              .replacingOccurrences(of: " ", with: " ", options: [], range: nil)
              .replacingOccurrences(of: "\"", with: "", options: NSString.CompareOptions.literal, range:nil)
          }
//    Set encoded values to Dict values you can decode keys if required
    dictData.forEach { (key, value) in
              if let val = value as? String {
                dictData[key] = self.percentEscapeString(val)
              } else {
                dictData[key] = value
              }
            }
