restapi怎么实现文件上传

第二部：创建工具类
public class WinkUtils {
public static ClientConfig getClientConfig(){
ClientConfig config=new ClientConfig();
SSLContext sc;
try {
sc=SSLContext.getInstance("SSL");
sc.init(null, getTrustManager(), new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
config.setBypassHostnameVerification(true);
config.connectTimeout(100000);
config.readTimeout(100000);
config.followRedirects(false);
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (KeyManagementException e) {
e.printStackTrace();
}
return config;
}

public static TrustManager[] getTrustManager(){
TrustManager[] trustAllCerts=new TrustManager[]{ new X509TrustManager(){
public void checkClientTrusted(X509Certificate[] arg0,String arg1) throws CertificateException {}
public void checkServerTrusted(X509Certificate[] arg0,String arg1) throws CertificateException {}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
}
};
return trustAllCerts;
}

}
第三步：写入图片数据到Bmob上
/**
* 功能：根据传入的url路径插入图片数据
* @param url 上传图片的url路径
* @param data 传入到Bmob中的图片二进制数据
* @return 插入成功返回的json格式字符串
*/
public static String setInsertGoodsData(String url,byte[] data){
String result=null;
RestClient restClient=new RestClient(WinkUtils.getClientConfig());
Resource resource=restClient.resource(url);
resource.header("X-Bmob-Application-Id", "你自己的APPID");
resource.header("X-Bmob-REST-API-Key",“你自己的APPKEY”);
resource.header("Content-Type", "image/jpeg");

ClientResponse response=resource.post(data);
int code=response.getStatusCode();
System.out.println("结果码:"+code);
if(code==201){
result=response.getEntity(String.class);
}
return result;
}
根据返回的result当中就包含图片上传之后在Bmob上的路径。操作完毕。
