How to use aggregated data

Question 1: How to use the aggregated data API? This is very simple. After registering, look at which API you want and click Apply for Data. After the application is approved, you can get the APPkey. .

Question 2: The main functions of aggregated data Mobile phone aggregation: The mobile phone aggregation data platform is the first original data service platform in China specially provided for the development of smart phones. Provide calling services for tens of millions of professional data including LBS, information, public relations, transportation, daily life and other categories. Website aggregation: The website aggregation platform provides free data query, data call, and data update services to website users. JS can be called with one click to steadily increase website traffic. LBS aggregation: The LBS location service platform provides various location-based query and calling services for free. Users can query LBS location information through the platform, and developers can call APIs for free. LBS (Location Based Service) location query service is widely used in various fields such as business, medical, industry and personal life. 1. Location query service for ordinary users. 2. Open API service for developers. Users can use the LBS homepage that aggregates data to Perform related queries based on IP address, longitude and latitude, address, and mobile phone base station information.

Question 3: Who knows how to use aggregated data? Teach me how to find personal data. You can directly use some tools to aggregate data and then analyze it, such as this. . .

Question 4: How to use aggregated data in android studio? First, register and apply for the API you want to use (strictly speaking, it is data, but the data is indeed obtained through the API). At first, the author thought it was still I need to verify my ID card, but I found out after trying it that it is not necessary, so I will not describe the steps in detail. I chose the weather forecast under the weather forecast (there is also a national weather 2015.07.03). After the application is successful, there will be an operation menu in My Data, with "Interface" below

Question 5: How to use the Android development aggregated data API in the project? This is very simple. After registration, you will see which API you want. Click to apply. After the data application is approved, you can get the APPkey. .

Question 6: Functional classification of aggregated data Aggregated data is a comprehensive cloud data platform that provides raw data API services for smartphone developers, webmasters, mobile device developers and graphic dealers. It includes three parts: mobile phone aggregation, website aggregation and LBS aggregation. Aggregated data provides developers with base station data, China Unicom base stations and telecommunications base stations for free, covering public transportation information data, food, clothing, housing and transportation, finance, LBS data and various other valid and legal information data in more than 1,000 major cities at home and abroad. API calls are flexible and convenient, and support developer data customization services.

Functional classification:

Mobile phone aggregation

The mobile phone aggregation data platform is the first original data service platform in China specially provided for the development of smart phones. Provide calling services for tens of millions of professional data including LBS, information, public relations, transportation, daily life and other categories.

Website aggregation

The website aggregation platform provides free data query, data call and data update services to website users. JS can be called with one click to steadily increase website traffic.

LBS aggregation

The LBS location service platform provides various location-based query and calling services for free. Users can query LBS location information through the platform, and developers can call APIs for free.

LBS (Location Based Service) location query service is widely used in various fields such as business, medical, industry and personal life (1) Location query service for ordinary users (2) Open API provided by developers Service users can make relevant queries based on IP address, latitude and longitude, address, and mobile phone base station information on the LBS homepage that aggregates data.

Question 7: Regarding how to use the Android development aggregated data API in the project, you can learn about network requests and json parsing

Question 8 : How to use aggregation transformation to aggregate values ??in the data set that cannot be converted

Question 9: How to parse the data through the nba interface of aggregated data. Java parsing JSON steps

1. The server side converts the data Convert to json string

First, the server-side project needs to import the json jar package and the jar package that json depends on to the builtPath path.

Then convert the data into a json string. The core function is:

public static String createJsonString(String key, Object value)

{

JSONObject jsonObject = new JSONObject();

jsonObject.put(key, value);

return jsonObject.toString();

}

2. The client converts the json string to The corresponding javaBean

The client obtains the json string (because the json jar package has been integrated in the android project, so there is no need to import it here)

public class HttpUtil

{

public static String getJsonContent(String urlStr)

{

try

{ Get the HttpURLConnection connection object

URL url = new URL(urlStr);

HttpURLConnection Conn = (HttpURLConnection) url

.openConnection();

Set connection properties

Conn.setConnectTimeout(3000);

Conn.setDoInput(true);

Conn.setRequestMethod(GET);

Get the corresponding code

int respCode = Conn.getResponseCode();

if (respCode == 200)

{

return ConvertStream2Json(Conn.getInputStream( ));

}

}

catch (MalformedURLException e)

{

TODO Auto-generated catch block

e.printStackTrace();

p> }

catch (IOException e)

{

TODO Auto-generated catch block

e.printStackTrace();

}

return ;

}

private static String ConvertStream2Json(InputStream inputStream)

{

String jsonStr = ;

ByteArrayOutputStream is equivalent to the memory output stream

ByteArrayOutputStream out = new ByteArrayOutputStream();

byte[] buffer = new byte [1024];

int len ??= 0;

Transfer the input stream to the memory output stream

try

{

while ((len = inputStream.read(buffer, 0, buffer.length)) != -1)

{

out.write(buffer, 0 , len);

}

Convert memory stream to string

jsonStr = new String(out.toByteArray());

}

catch (IOExceptio...gt; gt;

Question 10: How to parse the JSON data of android.aggregated data? Use json parsing in java java There are a lot of open source components

Gson comes from google company, has good performance, and is used more in android client

Jackson is known as the best performance

fastjson is open sourced by alibaba company and claims to have better performance than Jackson

Just find a component, read the official documentation, practice a few demos, and you will be able to get started soon
