删除请求参数 URL Volley android

Question

我有一个带有这样删除功能的 API：

http://localhost/v1/deletePost/:id

当我尝试在邮递员中通过在 url ":id" 中输入参数成功时，例如 ../deletePost/37"。

如何使用Volley库在android中实现“/:id”请求？

这里是guide关于如何使用 Volley Library

在发送简单请求的页面上：

final TextView mTextView = (TextView) findViewById(R.id.text);
//...

// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(this);
String url ="http://www.google.com";

// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, 
new Response.Listener<String>() {
    @Override
    public void onResponse(String response) {
        // Display the first 500 characters of the response string.
        mTextView.setText("Response is: "+ response.substring(0,500));
    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        mTextView.setText("That didn't work!");
    }
});
// Add the request to the RequestQueue.queue.add(stringRequest);

然后您需要将 GET 更改为 DELETE Request.Method.DELETE 并将您的 url 的 url 更改为 id http://localhost/v1/deletePost/37

会是这样的：

String baseUrl ="http://localhost/v1/deletePost/";
String url = baseUrl + "3" //Here you change the ID, can put as variable

// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.DELETE, url, 
new Response.Listener<String>() {
    @Override
    public void onResponse(String response) {
        // Display the first 500 characters of the response string.
        mTextView.setText("Response is: "+ response.substring(0,500));
    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        mTextView.setText("That didn't work!");
    }
});
