iOS Swift Http请求post方法使用头x-www-form-urlencoded？
我必须使用头作为JSON字符串的iOS Swift Http请求post方法使用头x-www-form-urlencoded？,ios,swift,xcode,alamofire,nsurlsessiondatatask,Ios,Swift,Xcode,Alamofire,Nsurlsessiondatatask,我必须使用头作为JSON字符串的application/x-www-form-urlencoded值进行API调用。当在postman中给出参数值和标题时，它工作正常并返回状态代码200ok。这里我使用的是后端节点js。Post方法在前端不起作用。不知道是什么问题 错误： Sometimes i am getting request time out, NSUrlfailingstring, finished with status code 1001 以下是我的后端代码： var st

非常感谢任何帮助。我看到了你的代码，你应该调用你为它创建的头参数。您在alamofire请求方法中没有传递头 如下图所示：
let headers: HTTPHeaders = ["Content-Type" :"application/x-www-form-urlencoded"]
let parameters : [String:Any] = ["count":post.likeCount!, "likedby":currentName, "postId=":postItem, "token": post.token!]
Alamofire.request("http://highavenue.co:9000/likesnotification/", method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers).responseJSON { (response:DataResponse<Any>) in
switch(response.result) {
case .success(_):
if let data = response.result.value{
print(data)
}
break
case .failure(_):
print(response.result.error as Any)
break
}
}
}
let headers:HTTPHeaders=[“内容类型”：“application/x-www-form-urlencoded”]
let参数：[String:Any]=[“count”：post.likeCount！，“likedby”：currentName，“postId=”：postItem，“token”：post.token！]
Alamofire.request（“http://highavenue.co:9000/likesnotification/，方法：.post，参数：参数，编码：JSONEncoding.default，标题：headers.responseJSON{（响应：DataResponse）in
开关（response.result）{
成功案例：
如果let data=response.result.value{
打印（数据）
}
打破
案例.失败（uu）：
打印（response.result.error，如有）
打破
}
}
}
