Android Volley-如何发送原始文本和获取json响应

String url = "http://example.com/api/endpoint";
String requestBody = "This is the raw text to be sent";

StringRequest request = new StringRequest(Request.Method.POST, url,
        response -> {
            // 处理响应
        },
        error -> {
            // 处理错误
        }) {
    @Override
    public byte[] getBody() {
        return requestBody.getBytes();
    }

    @Override
    public String getBodyContentType() {
        return "text/plain";
    }
};

// 将请求添加到请求队列
Volley.newRequestQueue(context).add(request);

String url = "http://example.com/api/endpoint";

JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
        response -> {
            // 处理响应
        },
        error -> {
            // 处理错误
        });

// 将请求添加到请求队列
Volley.newRequestQueue(context).add(request);
