在php代码中，每次尝试检索即将到来的值时，请尝试使用utf8_解码（$_REQUEST['REQUEST_value']）。经过长时间搜索，我发现了许多结果。。。他们都没有解决我的问题。。但是从这些结果中，我知道了是什么导致了这个问题。。因此，对于每个有同样问题的人，我要这样做：
A/首先检查您的数据库（我的问题就在这里）。
在phpMyAdmin中创建数据库时，选择utf8\u general\u ci
请参见屏幕截图：
以下是我的表格结构：
B/转到java源代码并添加以下内容：（在我的例子中）
而不是：
entity.addPart("Msg", new StringBody("HERE IS THE STRING éçèà"));
而不是发布“您的字符串”发布“urlcoder.encode（msg））”
C/现在转到php代码并解码url编码字符串
在我的情况下（在将其插入数据库之前）：
现在我用这个：
$Msg = $_REQUEST['Msg'];
$Msg= $db->real_escape_string(htmlentities(urldecode($Msg)));
而不仅仅是使用：
$Msg = $_REQUEST['Msg'];
这是我的java代码：
private void uploadFile(String filePath) {
try {
try {
HttpPost httpost = new HttpPost(url_upload);
MultipartEntity entity = new MultipartEntity();
entity.addPart("Mdp", new StringBody(mdp));
entity.addPart("Msg", new StringBody(URLEncoder.encode(msg)));
entity.addPart("type", new StringBody(type));
if(type.equals("1")) {
entity.addPart("Emailm", new StringBody(email));
entity.addPart("Emailp", new StringBody(emaildest));
}else {
entity.addPart("Emailp", new StringBody(email));
entity.addPart("Emailm", new StringBody(emaildest));
}
if (attach){
entity.addPart("attachement", new FileBody(new File(filePath)));
entity.addPart("attacher", new StringBody("oui"));
}else{
entity.addPart("attacher", new StringBody("non"));
}
httpost.setEntity(entity);
HttpResponse response;
HttpClient httpclient = new DefaultHttpClient();
response = httpclient.execute(httpost);
if (response != null) {
HttpEntity entity2 = response.getEntity();
String responseString = EntityUtils.toString(entity2, "UTF-8");
System.out.println(responseString);
json2=new JSONObject(responseString);
} else { //erreur
}
} catch (IOException e) {
e.printStackTrace();
}
}catch (Exception e){
}
}
这是php代码：

没用..我想问题出在javacodeok，mybe。。。。在一个开发中，我遇到了同样的问题。。。“utf8_解码”帮我解决这个问题。如果您尝试“utf8\U解码”，但这无助于您解决问题。。所以很抱歉目前没有更多的解决方案。请参阅我的答案@ToukeaTatsi
