java请求python的x-www-form-urlencoded接口

研究了半天= =|||终于成功了，python的post接口和java的不太一样,python不同的包的接口是不是一样不太了解。

我这边请求的是tornado的post接口

先加个依赖:

gradle:         

compile "commons-httpclient:commons-httpclient:3.1"

spring:

<dependency>

<groupId>commons-httpclient</groupId>

<artifactId>commons-httpclient</artifactId>

 <version>3.1</version>

</dependency>

java代码：

//获得post结果字符串
    public String getResult(String text){
        String url = "改成你的请求地址"; //请求地址
        String reStr = "请求返回错误";
        try {
            reStr = sendPost(url, text);
        } catch (Exception e) {
            e.printStackTrace();
        }

        return decodeUnicode(reStr);
    }

    private String sendPost(String postURL, String text) throws Exception{
        PostMethod postMethod = new PostMethod(postURL) ;
        postMethod.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8") ;
        //参数设置，需要注意的就是里边不能传NULL，要传空字符串

        NameValuePair[] data = {
　　　　　　　　new NameValuePair("param1","test")，

　　　　　　　　new NameValuePair("param2",text)    //post参数，pyhton的post接口的格式类似form表单

　　　　 };
        postMethod.setRequestBody(data);
        org.apache.commons.httpclient.HttpClient httpClient = new org.apache.commons.httpclient.HttpClient();
        httpClient.executeMethod(postMethod);
        String result = postMethod.getResponseBodyAsString() ;
        return result;
    }

    // unicode -> 汉字  处理python接口可能出现的unicode乱码   要是没有汉字乱码问题就不用
    public static String decodeUnicode(String theString) {
        char aChar;
        int len = theString.length();
        StringBuffer outBuffer = new StringBuffer(len);
        for (int x = 0; x < len;) {
            aChar = theString.charAt(x++);
            if (aChar == '\') {
                aChar = theString.charAt(x++);
                if (aChar == 'u') {
                    // Read the xxxx
                    int value = 0;
                    for (int i = 0; i < 4; i++) {
                        aChar = theString.charAt(x++);
                        switch (aChar) {
                            case '0':
                            case '1':

                            default:

                        }

                    }
                    outBuffer.append((char) value);
                } else {
