## 安卓平台接入OneNET方法:
**①注册一个中移物联网的账号**

**为设备添加APIKey,这也是之后程序里要用到的**
![](https://img2020.cnblogs.com/other/1617275/202003/1617275-20200318084540657-1452542764.png)
**保存设备APIKey**

**接下来为设备创建数据流,所有的数据都是被上传到数据流的
这里进行查看数据流**

**这里添加数据流**

接下来就是程序方面的实现
使用http协议,具体的协议内容可以查看
https://open.iot.10086.cnhttps://img.qb5200.com/download-x/doc/art/id/190#43
具体二进制文件的传输看这个网址
https://open.iot.10086.cnhttps://img.qb5200.com/download-x/doc/art258.html#68
以下http协议代码的实现都是基于这个规定的,一定要打开对照来看
### (1) 以POST实现文本数据的上传
```
public class OneNETUrlConnectionPost extends Thread {
private int SHOW_REQUEST = 0;
private Handler handler;
// 首先声明设备ID及apikey
private static final String DeviceID = "25857699";
// 个人使用就建议填产品key,设备key在二进制获取那里会权限不足
private static final String ApiKey = "QMrXbErb2t8h=E1mHORgxX20QVM=";
public OneNETUrlConnectionPost(Handler handler) {
this.handler = handler;
}
@Override
public void run() {
URL url;
HttpURLConnection connection;
try {
/https://img.qb5200.com/download-x/data1代表云端的数据流是data1
String s1 = new String(",;" + "data1" + "," + "哈哈哈,终于成功了");
byte[] data = s1.getBytes();
// 先new出一个URL对象,传入网络地址
// 调用openConnection()方法获取到HttpURLConnection对象
// 自己创建的中移物联网的地址http://api.heclouds.comhttps://img.qb5200.com/download-x/devices/25857699https://img.qb5200.com/download-x/datapoints?type=5
url = new URL("http://api.heclouds.comhttps://img.qb5200.com/download-x/devices/" + DeviceID
+ "https://img.qb5200.com/download-x/datapoints?type=5");
connection = (HttpURLConnection) url.openConnection();
// 下面使一些自由的定制,比如设置连接超时,读取超时的毫秒数,以及服务器希望得到的一些消息头
connection.setConnectTimeout(8000);
connection.setReadTimeout(8000);
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("api-key", ApiKey);
connection.setRequestProperty("Content-Length",
String.valueOf(data.length));
connection.setChunkedStreamingMode(5);
// 设置打开输出流
connection.setDoOutput(true);
// 拿到输出流
OutputStream os = connection.getOutputStream();
// 使用输出流往服务器提交数据
os.write(data);
os.flush();
os.close();
// //如果请求发送成功
if (connection.getResponseCode() == 200) {
// 接下来利用输入流对数据进行读取
InputStream is = connection.getInputStream();
BufferedReader br = new BufferedReader(
new InputStreamReader(is));
StringBuilder response = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
response.append(line);
}// 正常则返回{"errno":0,"error":"succ"},此函数为void,用不上这个
// 发送数据完毕,接下来用Handler进行提交成功显示
Message message = new Message();
message.what = SHOW_REQUEST;
message.obj = response.toString();
handler.sendMessage(message);
}
// 最后关闭HTTP连接
connection.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
}
}
```
### (2) 以POST实现字节数据的上传(包括图片视频等二进制文件)
```
public class OneNETUrlConnectionPostByte extends Thread {
private int SHOW_REQUEST = 0;
private Handler handler;
// 首先声明设备ID及apikey
private static final String DeviceID = "25857699";
// 个人使用就建议填产品key,设备key在二进制获取那里会权限不足
private static final String ApiKey = "QMrXbErb2t8h=E1mHORgxX20QVM=";
public OneNETUrlConnectionPostByte(Handler handler) {
this.handler = handler;
}
@Override
public void run() {
URL url;
// 自定义的字符数组将它上传到云端
byte[] my_data = { '8', '8', '6' };
HttpURLConnection connection;
try {
// 先new出一个URL对象,传入网络地址
// 调用openConnection()方法获取到HttpURLConnection对象
// 自己创建的中移物联网的地址http://api.heclouds.comhttps://img.qb5200.com/download-x/devices/25857699https://img.qb5200.com/download-x/datapoints?type=5
url = new URL("http://api.heclouds.com/bindata?device_id="
+ DeviceID + "&datastream_id=" + "data123");
connection = (HttpURLConnection) url.openConnection();
// 下面使一些自由的定制,比如设置连接超时,读取超时的毫秒数,以及服务器希望得到的一些消息头
connection.setConnectTimeout(8000);
connection.setReadTimeout(8000);
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("api-key", ApiKey);
connection.setRequestProperty("Content-Length",
String.valueOf(my_data.length));
connection.setChunkedStreamingMode(5);
// 设置打开输出流
connection.setDoOutput(true);
// 拿到输出流
OutputStream os = connection.getOutputStream();
// 使用输出流往服务器提交数据
os.write(my_data);
os.flush();
os.close();
// //如果请求发送成功
if (connection.getResponseCode() == 200) {
// 接下来利用输入流对数据进行读取
InputStream is = connection.getInputStream();
BufferedReader br = new BufferedReader(
new InputStreamReader(is));
StringBuilder response = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
response.append(line);
}// 正常则返回{"errno":0,"error":"succ"},此函数为void,用不上这个
// 发送数据完毕,接下来用Handler进行提交成功显示
Message message = new Message();
message.what = SHOW_REQUEST;
message.obj = response.toString();
handler.sendMessage(message);
}
// 最后关闭HTTP连接
connection.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
}
}
```
### (3) 以GET实现文本数据的获取
```
public class OneNETHttpRequestGET extends Thread {
private int SHOW_REQUEST = 0;
private Handler handler;
// 首先声明设备ID及apikey
private static final String DeviceID = "25857699";
// 个人使用就建议填产品key,设备key在二进制获取那里会权限不足
private static final String ApiKey = "QMrXbErb2t8h=E1mHORgxX20QVM=";
public OneNETHttpRequestGET(Handler handler) {
this.handler = handler;
}
@Override
public void run() {
URL url;
HttpURLConnection connection;
try {
// 先new出一个URL对象,传入网络地址
// 调用openConnection()方法获取到HttpURLConnection对象
url = new URL("http://api.heclouds.comhttps://img.qb5200.com/download-x/devices/" + DeviceID
+ "https://img.qb5200.com/download-x/datastreams/" + "data1");
connection = (HttpURLConnection) url.openConnection();
// 下面使一些自由的定制,比如设置连接超时,读取超时的毫秒数,以及服务器希望得到的一些消息头
connection.setConnectTimeout(15000);
connection.setReadTimeout(15000);
connection.setRequestMethod("GET");
connection.setRequestProperty("api-key", ApiKey);
// 如果网页正确响应
if (connection.getResponseCode() == 200) {
// 接下来利用输入流对数据进行读取
InputStream is = connection.getInputStream();
BufferedReader br = new BufferedReader(
new InputStreamReader(is));
StringBuilder response = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
response.append(line);
}
// 读取数据完毕,接下来将数据传送到Handler进行显示
Message message = new Message();
message.what = SHOW_REQUEST;
message.obj = response.toString();
handler.sendMessage(message);
// 最后关闭HTTP连接
connection.disconnect();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
```
### (4) 以GET实现字节数据的获取,但是存在小bug还未成功
```
public class OneNETHttpRequestGETByte extends Thread {
private int SHOW_REQUEST = 0;
private Handler handler;
// 首先声明设备ID及apikey
private static final String DeviceID = "25857699";
// 个人使用就建议填产品key,设备key在二进制获取那里会权限不足
private static final String ApiKey = "QMrXbErb2t8h=E1mHORgxX20QVM=";
public OneNETHttpRequestGETByte(Handler handler) {
this.handler = handler;
}
@Override
public void run() {
URL url;
HttpURLConnection connection;
try {
// 先new出一个URL对象,传入网络地址
// 调用openConnection()方法获取到HttpURLConnection对象
url = new URL("http://api.heclouds.com/bindata/"
+ "25857699_15201013688560_data123");
connection = (HttpURLConnection) url.openConnection();
// 下面使一些自由的定制,比如设置连接超时,读取超时的毫秒数,以及服务器希望得到的一些消息头
connection.setConnectTimeout(15000);
connection.setReadTimeout(15000);
connection.setRequestMethod("GET");
connection.setRequestProperty("api-key", ApiKey);
// 如果网页正确响应
if (connection.getResponseCode() == 200) {
// 接下来利用输入流对数据进行读取
InputStream is = connection.getInputStream();
BufferedReader br = new BufferedReader(
new InputStreamReader(is));
StringBuilder response = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
response.append(line);
}
// 读取数据完毕,接下来将数据传送到Handler进行显示
Message message = new Message();
message.what = SHOW_REQUEST;
message.obj = response.toString();
handler.sendMessage(message);
// 最后关闭HTTP连接
connection.disconnect();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
```
