Precautions for calling e-commerce API, you must know these!

    With the rapid development of the e-commerce industry, more and more companies have begun to use e-commerce APIs for development and invocation. As a bridge between the e-commerce platform and third-party applications, the e-commerce API interface can realize functions such as data sharing, operation authorization, and fast transactions, and has become a powerful tool for enterprise development. However, when using the e-commerce API, you need to pay attention to the following points:

1. Check the documentation: Before using the API, check the corresponding documentation. Documentation contains detailed descriptions of interfaces, request/response parameters, and sample codes, which are very important for developers. By reading the documentation, you can have a clearer understanding of how to use the API interface and related restrictions.

2. Reasonably set the frequency: When making API calls, pay attention to setting the call frequency reasonably, and do not call the API interface frequently, otherwise the API service may not respond or be restricted, which will affect the normal operation of the business. At the same time, it is also necessary to pay attention to the call times and quota limits of the API interface, so as to avoid exceeding the limit and causing the interface to be unusable.

3. Data security: When using the API interface, you need to pay attention to data security. During the data transmission process, HTTPS and other encryption technologies should be used reasonably to ensure the security of the data transmission process. In addition, when data is extracted and stored, the confidentiality of data needs to be considered to protect the privacy and personal information of users.

4. Exception handling: In the process of calling the API interface, various abnormal situations may occur, such as network errors, incorrect data formats, etc. In this case, exceptions need to be handled reasonably to avoid business impact. For different exception situations, you can consider using try...catch or custom exception handling methods.

5. Set request parameters reasonably: When making an API call, you need to set request parameters reasonably. According to business needs, select the appropriate interface, request parameters and data format, etc., to ensure the accuracy and integrity of the data. At the same time, it is also necessary to pay attention to standardization in parameter settings to avoid non-standard parameter settings that cause API services to not respond or be restricted.

		StringBuilder sb = new StringBuilder();
		int cp;
		while ((cp = rd.read()) != -1) {
			sb.append((char) cp);
		}
		return  sb.toString();
	}
	public static JSONObject postRequestFromUrl(String url, String body) throws IOException, JSONException {
		URL realUrl = new URL(url);
		URLConnection conn = realUrl.openConnection();
		conn.setDoOutput(true);
		conn.setDoInput(true);
		PrintWriter out = new PrintWriter(conn.getOutputStream());
		out.print(body);
		out.flush();
		InputStream instream = conn.getInputStream();
		try {
			BufferedReader rd = new BufferedReader(new InputStreamReader(instream, Charset.forName("UTF-8")));
			String jsonText = readAll(rd);
			JSONObject json = new JSONObject(jsonText);
			return json;
		} finally {
			instream.close();
		}
	}
	public static JSONObject getRequestFromUrl(String url) throws IOException, JSONException {
		URL realUrl = new URL(url);
		URLConnection conn = realUrl.openConnection();
		InputStream instream = conn.getInputStream();
		try {
			BufferedReader rd = new BufferedReader(new InputStreamReader(instream, Charset.forName("UTF-8")));
			String jsonText = readAll(rd);
			JSONObject json = new JSONObject(jsonText);
			return json;
		} finally {
			instream.close();
		}
	}
	public static void main(String[] args) throws IOException, JSONException {
		// 请求示例 测试API请+V15870092527
		String url = "https://api-服务器.cn/taobao/item_get/?key=<您自己的apiKey>&secret=<您自己的apiSecret>&num_iid=652874751412&is_promotion=1";
		JSONObject json = getRequestFromUrl(url);
		System.out.println(json.toString());
	}

}

To sum up, e-commerce API calls need to pay attention to many details, from viewing documents to exception handling to request parameter settings, etc., which need to be taken seriously by developers and strictly implemented. Only in this way can we better enjoy the convenience and efficiency brought by API, and make greater contributions to the presentation and innovation of enterprise business.
