Question

我想进行一项更改用户配置文件的活动。接收到的基于JSON的部分正常运行。我已经在PHP代码中手动测试了set变量。但是，当我将变量从android发布到php时，它无法接收它。有人可以告诉我问题吗？

import {
    users
} from "../models/main.js"


const myRanking = document.querySelector("#usersRank")

renderRankings();

function renderRankings(){

    let result3 = ""


    for(const user of users) {
        result3 += `
    <div>


    <style>
table, th, td {
  border: 1px solid green;
  border-collapse: collapse;
}
</style>

    <table style="width:50%">
  <tr>
    <th>Nome</th>
    <th>XP</th> 
  </tr>
  <tr>
    <td>${user.username}</td>
    <td>${user.xp}</td>
  </tr>
</table>

    </div>
    `


        myRanking.innerHTML = result3;



    }
}

有同样的问题无法弄清楚问题出在哪里，但这可以解决问题，请不要忘记在gradle文件中添加依赖项

import networkx as nx
from collections import defaultdict

G = nx.karate_club_graph()
avg_neigh_degrees = nx.algorithms.assortativity.average_neighbor_degree(G)
deg_to_avg_neighbor_degrees = defaultdict(list)
for node, degree in nx.degree(G):
    deg_to_avg_neighbor_degrees[degree].append(avg_neigh_degrees[node])

# this is the same as nx.algorithms.assortativity.average_degree_connectivity(G)
avg_degree_connectivity = {degree: sum(vals)/len(vals) for degree, vals in
                           deg_to_avg_neighbor_degrees.items()}

尝试如下修改您的loadProifle（）方法

     // define below variable to globally
     String mRequestBody=null;


     private void loadProfil() {
    try {
        JSONObject jsonBody = new JSONObject();
        jsonBody.put("namekey", "paste here name");
        jsonBody.put("emailkey", "paste here email");
        jsonBody.put("passkey", "paste here password");
        jsonBody.put("nokey", "paste here number");
        mRequestBody = jsonBody.toString();
    }catch(JSONException e){
        e.printStackTrace();
    }
    StringRequest stringRequest = new StringRequest(Request.Method.POST, PROFIL_URL, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            try {
                JSONArray profil = new JSONArray(response);

                JSONObject profilObject = profil.getJSONObject(0);

                String foto_user = profilObject.getString("foto_user");
                String username = profilObject.getString("username");
                String email = profilObject.getString("email");
                String password = profilObject.getString("password");
                String nohp = profilObject.getString("nohp");

                Profil viewProfil = new Profil(foto_user, username, email, password, nohp);
                profilList.add(viewProfil);

                editTextNama.setText(username);
                editTextEmail.setText(email);
                editTextPassword.setText(password);
                editTextNohp.setText(nohp);

            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Toast.makeText(ProfilActivity.this, error.getMessage() + "Error Load Profil", Toast.LENGTH_LONG).show();
        }
    }){
        @Override
        public byte[] getBody() throws AuthFailureError {
            try {
                return mRequestBody == null ? null : mRequestBody.getBytes("utf-8");
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
                return null;
            }
        }
    };
    Volley.newRequestQueue(this).add(stringRequest);
}

这是我的PHP代码，用于获取电子邮件变量。有什么问题吗？

<?php

define('DB_HOST','Localhost');
define('DB_USER','id9815170_phpjember');
define('DB_PASS','phpjember');
define('DB_NAME','id9815170_phpjember');

$conn = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);

if(mysqli_connect_errno()){
    die('Unable to connect to database ' . mysqli_connect_error());
}

$email = $_POST['email'];

$stmt = $conn->prepare("SELECT foto_user, username, email, password, nohp FROM datauser WHERE email='$email';");

$stmt->execute();

$stmt->bind_result($foto_user, $username, $email, $password, $nohp);

$profil = array();

while($stmt->fetch()){

    $temp = array();
    $temp['foto_user'] = $foto_user;
    $temp['username'] = $username;
    $temp['email'] = $email;
    $temp['password'] = $password;
    $temp['nohp'] = $nohp;

    array_push($profil, $temp);
}
echo json_encode($profil);
