如何使用Alamofire 4在HTTP正文中发送带有数据的POST请求？我在
swift 2.3上使用自定义编码它运行良好.我转换了我的代码swift 3,我尝试使用paramater编码,但没有工作.这段代码：
public struct MyCustomEncoding : ParameterEncoding {
private let data: Data
init(data: Data) {
self.data = data
}
public func encode(_ urlRequest: URLRequestConvertible,with parameters: Parameters?) throws -> URLRequest {
var urlRequest = try urlRequest.asURLRequest()
do {
urlRequest.httpBody = data
urlRequest.setValue("application/json",forHTTPHeaderField: "Content-Type")
} catch {
throw AFError.parameterEncodingFailed(reason: .jsonEncodingFailed(error: error))
}
return urlRequest
}
和Alamofire要求：
let enco : ParameterEncoding = MyCustomEncoding(data: ajsonData)
Alamofire.request(urlString,method: .post,parameters: [:],encoding: enco,headers: headers).validate()
.responseJSON { response in
switch response.result {
case .success:
print(response)
break
case .failure(let error):
print(error)
}
}
解决方法
您需要在swift 3中发送如下所示的请求
let urlString = "https://httpbin.org/get"
Alamofire.request(urlString,parameters: ["foo": "bar"],encoding: JSONEncoding.default,headers: nil).responseJSON {
response in
switch response.result {
case .success:
print(response)
break
case .failure(let error):
print(error)
}
}
