Volley学习(一)Android Volley源码解析
Volley学习(二)简封Volley、为Volley请求头体添加Json参数、Gson和JsonObject生成Json数据、Gson解析返回的Json
Volley学习(三)ImageRequest、ImageLoader、NetworkImageView源码简读
Volley学习(四)NetworkImageView+LruCache（源码简读）图片请求小例子
这篇博客是来了解下，头像上传如何实现，我们httpurlconnection和Volley来实现
首先了解下布局文件
我们先看httpurl如何实现头像上传的？
头像上传其实本质上就是将某个需要上传的图片转为byte[]数组，然后在通过Base64.encodeToString转为字符串
首先添加头部体部分，用来生成json字符串，这里说一下，我们公司是直接拼接的方式，当然你也可以用fastson、Gson、JsonObject来生成json格式
/** * 生成数据上传的头部，需要数据国鼎id，应用类型，操作系统类型 */ private void addUserInfosHead() { headParameters.clear(); headParameters.add("godin_id", "0e6ad2a71e31752deb69d6e8c9eabe76"); headParameters.add("app_type", "3"); headParameters.add("os_type", "android"); } /** * 生成数据上传的数据包体 */ private void addRequestBodyInfos() { bodyParameters.clear(); bodyParameters.add("photo_type", "jpeg"); bodyParameters.add("context", Base64.encodeToString(bitmap2Bytes, Base64.DEFAULT)); bodyParameters.add("nickname", nick_name.getText().toString()); }楼上的Base64.encodeToString(bitmap2Bytes, Base64.DEFAULT)就是将图片的二进制文件转为字符串
我们公司的封装代码中，以下代码就是生成json格式
requestion = ProtocolUtil.buildJSONPacketBody(headParameters, bodyParameters);看看Json格式把：
然后就是点击上传即可，我用的网络请求是https的，所以在initHttps中进行一些证书的认证之类的，然后就打开网络链接conn,然后就获取相应码即可
initHttps(); URL url = new URL(urlString); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.setConnectTimeout(5000); conn.setDoOutput(true);//设置允许输出 conn.setRequestMethod("POST"); conn.setRequestProperty("User-Agent", "Fiddler"); conn.setRequestProperty("Content-Type", "application/json"); conn.setRequestProperty("Charset", "utf-8"); OutputStream os = conn.getOutputStream(); os.write(content.getBytes()); os.close(); /*服务器返回的响应码*/ int code = conn.getResponseCode(); if (code == 200) { Log.d("Evelyn", "response code:" + code); } conn.disconnect();最后看返回结果即可
我们再看看Volley如何实现头像上传的？
之前的几篇博客中，有对volley、Gson的封装使用，本篇博客就简单使用即可
StringRequest request = new StringRequest(Method.POST, url, new Listener<String>() { @Override public void onResponse(String arg0) { Log.e("TAG", "volley onResponse--->>" + arg0); /** * {"Response":{"head":{"statuscode":"000000", * "statusmsg":"sucess"}}} */ } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError arg0) { } }) { @Override public byte[] getBody() throws AuthFailureError { return requestStringBytes; } @Override public String getBodyContentType() { return String.format( "application/x-www-form-urlencoded; charset=%s", "utf-8"); } @Override public Map<String, String> getHeaders() throws AuthFailureError { Map<String, String> headers = new HashMap<String, String>(); headers.put("Charset", "UTF-8"); headers.put("Content-Type", "application/x-javascript"); headers.put("Accept-Encoding", "gzip,deflate"); return headers; } }; // 设置标签 queue.add(request); queue.start();代码也很简单；
getBodyContentType这里是设置请求的东东的格式化
getHeaders这里也是设置一些需要的参数（我当时也是搜的百度，么有这些设置，无法相应正确返回值）
@Override public byte[] getBody() throws AuthFailureError { return requestStringBytes; }这个就是需要的body[] 我们就用httpurlconnect中的那个json字符串即可
requestStringBytes = requestion.getBytes("UTF-8");然后一样接受返回值即可，如下截图是本公司返回的json格式
