一個小工具類用來post json字串和檔案上傳並且帶引數外加忽略https證書認證

1 上傳檔案和引數

public class NetWorkUtilsHttps {
    public static final MediaType JSON = MediaType
            .parse("application/json; charset=utf-8");
    private OkHttpClient client;
    private SSLContext sslContext = null;

    public NetWorkUtilsHttps() {
        X509TrustManager xtm = new 
 
X509TrustManager() {
            @Override
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {

            }

            @Override
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {

            }

            @Override
 
public X509Certificate[] getAcceptedIssuers() {
                return new X509Certificate[0];
            }
        };
        try {
            sslContext = SSLContext.getInstance("SSL");
            sslContext.init(null, new TrustManager[]{xtm}, new SecureRandom());
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch 
 
(KeyManagementException e) {
            e.printStackTrace();
        }
        HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
            @Override
public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        };
        client = new OkHttpClient.Builder()
                .sslSocketFactory(sslContext.getSocketFactory())
                .readTimeout(50, TimeUnit.SECONDS)
                .connectTimeout(50, TimeUnit.SECONDS)
                .hostnameVerifier(DO_NOT_VERIFY)
                .build();
    }

//post  json  

  .addHeader("code", trsCode)

是加頭部的一些引數
public String post(String json, String code, String url) { RequestBody body = RequestBody.create(JSON, json); Request request = new Request.Builder() .url(url) .addHeader("code", trsCode).post(body).build(); try { Response response = client.newCall(request).execute(); if (response.isSuccessful()) { return response.body().string(); } response.body().close(); } catch (IOException e) { e.printStackTrace(); } return "{\"ROOT\":{\"BODY\":{\"info\":[]},\"HEAD\":{\"resCode\":\"545\",\"TrsAppType\":\"1\",\"resMsg\":\"連線伺服器失敗,請稍後重試!\"}}}"; } public String uploadFile(File file, String uniqueNo, String fileCode, String path) { StringBuffer resultBuffer = new StringBuffer(""); Map<String, String> params = new HashMap<>(); params.put("busiType", "0");//業務型別params.put("flag", "up");// 操作標誌：up-上傳 down-下載params.put("fileType", fileCode);//檔案所屬型別 code碼 引數MultipartBody.Builder form = new MultipartBody.Builder().setType(MultipartBody.FORM); StringBuffer buffer = new StringBuffer(); String url = path; url += "?"; for (String key : params.keySet()) { //新增引數buffer.append(key + "=" + params.get(key) + "&"); Log.e(key, params.get(key)); } url += buffer.toString(); if (url.lastIndexOf("&") != -1) { url = url.substring(0, url.lastIndexOf("&"));//拼接引數 }

//放檔案
        form.addPart(Headers.of("Content-Disposition", "form-data; name=\"file\";filename=\"" + file.getName() + "\""), RequestBody.create(MediaType.parse("image/png"), file));
        RequestBody body = form.build();
        Request request = new Request
                .Builder()
                .url(url)
                .addHeader("Connection", "keepAlive")
                .addHeader("Charset", "UTF-8")
                .post(body)
                .build();
        try {
            Response response = client.newCall(request).execute();
            if (response.isSuccessful()) {
                resultBuffer.replace(0, resultBuffer.length(), response.body().string());
                Log.e("upFileFlag", resultBuffer.toString());
                return resultBuffer.toString();
            } else {
                Log.e("error", response.body().string());
            }
            response.body().close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "{\"resCode\":\"099\",\"resMsg\":\"上傳檔案失敗\"}";
    }
