java http, https request tool

Using tools-httpclient can quickly send HTTP / HTTPS request in the project

Project use:

1. Add dependence:

<dependency>
    <groupId>cn.gjing</groupId>
    <artifactId>tools-httpclient</artifactId>
    <version>1.0.1</version>
</dependency>

1. Interface requires the use of direct use:

• HTTP request (GET case)

public static void main(String[] args) {    
    Map<String, String> map = new HashMap<>(16);
    map.put("a", "参数a");
    map.put("b", "参数b");
    //发送http请求
    String result = HttpClient.get("http://127.0.0.1:8080/test", map, String.class);
    System.out.println(result);
}

• HTTPS requests (POST Case)

public static void main(String[] args) {    
    Map<String, String> map = new HashMap<>(16);
    map.put("a", "参数a");
    map.put("b", "参数b");
    //发送https请求
    Map result = HttpClient.post("https://127.0.0.1:8080/test", map, Map.class);
    System.out.println(result.toString());
}

• DELETE Case

public static void main(String[] args) {    
    ResultBean result = HttpClient.delete("http://127.0.0.1:8080/test/1", ResultBean.class);
    System.out.println(result.toString());
}

• PUT Case

public static void main(String[] args) {    
    Integer result = HttpClient.put("https://127.0.0.1:8080/test/2", Integer.class);
    System.out.println(result);
}

Parameter Description HttpClient (except for any parameter required parameters need not be directly transmitted null):

• url : Request address (required)
• QueryMap : Request parameter
• headers : request header
• connectTimeout : Request timeout, default 5s
• ReadTimeout : reading timeout, default 10 seconds
• responseType : response result return type (required)
• jsonEntity : Json object may be a character string corresponding to json object map may be used
• jsonStr : Json string

tip: The best type of response returned results consistent with the targets set method, this may appear abnormal conversion

Target method

@GetMapping("/test")
public Integer test() {
    return 1111;
}

The caller

public static void main(String[] args) {
    Map result = HttpClient.get("http://127.0.0.1:8080/test", Map.class);
    System.out.println(result.toString());
}

Since the target method returns an Integer type, not a key, value type, so the caller will be converted using the Map receiving abnormal.

1. UrlUtil Tools

• urlAppend (for direct parameterized URL address)

    public static void main(String[] args) {
        String url = "http://127.0.0.1:8080/";
        Object[] param = {1, 2, 3, 4};
        System.out.println(UrlUtil.urlAppend(url, param));
    }
    输出结果为：http://127.0.0.1:8080/1/2/3/4/

• paramUnicodeSort (small according to Unicode code parameter field name to large order (lexicographical))

    public static void main(String[] args) {
        Map<String, Object> map = new HashMap<>(16);
        map.put("a", "参数1");
        map.put("b", "参数2");
        /*
            该方法带三个参数,分别为:
            paramMap: 参数
            urlEncode: 是否进行URL encode
            keyToLower: 转换后的参数的key值是否转为小写
         */
        System.out.println(UrlUtil.paramUnicodeSort(map, false, false));
    }
    输出结果为：a=参数1&b=参数2

• urlParamToMap (URL address with the parameter turn into Map)

    public static void main(String[] args) {
        String url = "http://127.0.0.1:8080?a=2&b=2";
        System.out.println(UrlUtil.urlParamToMap(url));
    }
    输出结果为：{a=2, b=2}
