kotlin中URLEncodedUtils.format（params，“utf-8”）的替代方法是什么？

我必须将键值对转换为Url查询参数有一个在Java中可用的函数： URLEncodedUtils.format(params, "utf-8")它在kotlin中的替代方法是什么？

Answer 1

 val param = ArrayList() 

然后添加你的参数，只写下面的代码

 object Parser { var result = HashMap() fun parseJsonObject(url: String, method: String, params: List): HashMap { var url = url var iStream: InputStream ?= null var data = "" println("url*************" + url) println("params*************" + params) var httpClient: DefaultHttpClient? = null try { // check for request method if (method === "POST") { // request method is POST // defaultHttpClient if (httpClient == null) { httpClient = DefaultHttpClient() } val httpPost = HttpPost(url) httpPost.entity = UrlEncodedFormEntity(params) // set timeout HttpConnectionParams.setConnectionTimeout(httpClient.params, 20000) HttpConnectionParams.setSoTimeout(httpClient.params, 30000) val httpResponse = httpClient.execute(httpPost) if (httpResponse.statusLine.statusCode === 200) { val httpEntity = httpResponse.entity iStream = httpEntity.content val br = BufferedReader( InputStreamReader(iStream!!, "utf8")) val sb = StringBuffer() var line = "" while ((line == br.readLine()) != null) { sb.append(line) } data = sb.toString() br.close() iStream.close() httpClient.connectionManager.closeExpiredConnections() result.put("code", "200") result.put("value", data) } else { httpClient.connectionManager.closeExpiredConnections() result.put("code", "9999") result.put("value", "") } } else if (method === "GET") { // request method is GET if (httpClient == null) { httpClient = DefaultHttpClient() } val paramString = URLEncodedUtils.format(params, "utf-8") url += "?" + paramString val httpGet = HttpGet(url) // set timeout HttpConnectionParams.setConnectionTimeout(httpClient.params, 20000) HttpConnectionParams.setSoTimeout(httpClient.params, 30000) val httpResponse = httpClient.execute(httpGet) if (httpResponse.statusLine.statusCode === 200) { val httpEntity = httpResponse.entity iStream = httpEntity.content val br = BufferedReader( InputStreamReader(iStream!!, "utf8")) val sb = StringBuffer() var line = "" while ((line == br.readLine()) != null) { sb.append(line) } data = sb.toString() br.close() iStream.close() httpClient.connectionManager.closeExpiredConnections() result.put("code", "200") result.put("value", data) } else { httpClient.connectionManager.closeExpiredConnections() result.put("code", "9999") result.put("value", "") } } } catch (e: Exception) { result.put("code", "9999") result.put("value", "") e.printStackTrace() return result } return result } 

}
