URL 使用 SwiftyJSON 编码 Alamofire GET 参数
URL Encode Alamofire GET params with SwiftyJSON
我试图让 Alamofire 在 GET 请求中发送以下参数,但它正在发送乱码:
filters={"$and":[{"name":{"$bw":"duke"},"country":"gb"}]}
//www.example.com/example?filters={"$and":[{"name":{"$bw":"duke"},"country":"gb"}]}
//Obviously URL encoded
这是我的代码:
let jsonObject = ["$and":[["name":["$bw":string], "country":"gb"]]]
let json = JSON(jsonObject)
print(json)
产出
{
"$and" : [
{
"name" : {
"$bw" : "duke"
},
"country" : "gb"
}
]
}
这是我的参数请求:
let params = ["filters" : json.rawValue, "limit":"1", "KEY":"my_key"]
这是 AlamoFire 发送的内容:
KEY=my_key&
filters[$and][][country]=gb&
filters[$and][][name][$bw]=duke&
limit=1
如您所见,过滤器参数一团糟。我做错了什么?
默认情况下,Alamofire 使用 POST 主体中的参数列表对参数进行编码。尝试将编码更改为 JSON
。这样,Alamofire 就会将字典序列化为 JSON 字符串,正如您所期望的那样:
let parameters = [
"foo": [1,2,3],
"bar": [
"baz": "qux"
]
]
Alamofire.request(.POST, "http://httpbin.org/post", parameters: parameters, encoding: .JSON)
// HTTP body: {"foo": [1, 2, 3], "bar": {"baz": "qux"}}
或使用您的代码:
let string = "duke"
let jsonObject = ["$and":[["name":["$bw":string], "country":"gb"]]]
let json = JSON(jsonObject)
let params = ["filters" : json.rawValue, "limit":"1", "KEY":"my_key"]
Alamofire.request(.POST, "http://httpbin.org/post", parameters: params, encoding: .JSON)
.responseString(encoding: NSUTF8StringEncoding) { request, response, content, error in
NSLog("Request: %@ - %@\n%@", request.HTTPMethod!, request.URL!, request.HTTPBody.map { body in NSString(data: body, encoding: NSUTF8StringEncoding) ?? "" } ?? "")
if let response = response {
NSLog("Response: %@\n%@", response, content ?? "")
}
}
获取输出:
Request: POST - http://httpbin.org/post
{"filters":{"$and":[{"name":{"$bw":"duke"},"country":"gb"}]},"limit":"1","KEY":"my_key"}
编辑:URL-在 GET 参数中编码 JSON
如果您想在 GET 参数中发送 URL 编码的 JSON,您必须首先生成 JSON 字符串,然后将其作为字符串传递到参数字典中:
SWIFT 1
let string = "duke"
let jsonObject = ["$and":[["name":["$bw":string], "country":"gb"]]]
let json = JSON(jsonObject)
// Generate the string representation of the JSON value
let jsonString = json.rawString(encoding: NSUTF8StringEncoding, options: nil)!
let params = ["filters" : jsonString, "limit": "1", "KEY": "my_key"]
Alamofire.request(.GET, "http://httpbin.org/post", parameters: params)
.responseString(encoding: NSUTF8StringEncoding) { request, response, content, error in
NSLog("Request: %@ - %@\n%@", request.HTTPMethod!, request.URL!, request.HTTPBody.map { body in NSString(data: body, encoding: NSUTF8StringEncoding) ?? "" } ?? "")
if let response = response {
NSLog("Response: %@\n%@", response, content ?? "")
}
}
SWIFT 2
let string = "duke"
let jsonObject = ["$and":[["name":["$bw":string], "country":"gb"]]]
let json = JSON(jsonObject)
// Generate the string representation of the JSON value
let jsonString = json.rawString(NSUTF8StringEncoding)!
let params = ["filters" : jsonString, "limit": "1", "KEY": "my_key"]
Alamofire.request(.GET, "http://httpbin.org/post", parameters: params)
.responseString(encoding: NSUTF8StringEncoding) { request, response, result in
NSLog("Request: %@ - %@\n%@", request!.HTTPMethod!, request!.URL!, request!.HTTPBody.map { body in NSString(data: body, encoding: NSUTF8StringEncoding) ?? "" } ?? "")
switch result {
case .Success(let value):
NSLog("Response with content: %@", value)
case .Failure(let data, _):
NSLog("Response with error: %@", data ?? NSData())
}
}
SWIFT 3 和 Alamofire 4.0
let string = "duke"
let jsonObject = ["$and":[["name":["$bw":string], "country":"gb"]]]
let json = JSON(jsonObject)
// Generate the string representation of the JSON value
let jsonString = json.rawString(.utf8)!
let params = ["filters" : jsonString, "limit": "1", "KEY": "my_key"]
Alamofire.request("http://httpbin.org/post", method: .get, parameters: params)
.responseString { response in
#if DEBUG
let request = response.request
NSLog("Request: \(request!.httpMethod!) - \(request!.url!.absoluteString)\n\(request!.httpBody.map { body in String(data: body, encoding: .utf8) ?? "" } ?? "")")
switch response.result {
case .success(let value):
print("Response with content \(value)")
case .failure(let error):
print("Response with error: \(error as NSError): \(response.data ?? Data())")
}
#endif
}
这会生成一个包含以下内容的 GET 请求 URL:
http://httpbin.org/post?KEY=my_key&filters=%7B%22%24and%22%3A%5B%7B%22name%22%3A%7B%22%24bw%22%3A%22duke%22%7D%2C%22country%22%3A%22gb%22%7D%5D%7D&limit=1
URL-解码后是:
http://httpbin.org/post?KEY=my_key&filters={"$and":[{"name":{"$bw":"duke"},"country":"gb"}]}&limit=1
我试图让 Alamofire 在 GET 请求中发送以下参数,但它正在发送乱码:
