空$ _POST和$ _FILES与请求类型的multipart / form-data的 [英] empty $_POST and $_FILES with request type multipart/form-data
本文介绍了空$ _POST和$ _FILES与请求类型的multipart / form-data的的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想从Android应用程序发送POST请求到服务器。在这一请求，我想送一些文本数据（JSON）和图片。
但我不能得到这个服务器的数据。变量$ _FILES，$ _ POST，甚至PHP：//输入为空。但是数据确实传输到服务器，因为在$ _ SERVER我能找到这样的：
[REQUEST_METHOD] =＆GT; POST
[内容] =＆GT;的multipart / form-data的;边界= Jq7oHbmwRy8793I27R3bjnmZv9OQ_Ykn8po6aNBj;字符集= UTF-8
[CONTENT_LENGTH] =＆GT; 53228
有什么问题可以用这个？结果
的服务器是nginx的1.1结果
PHP版本5.3.6-13ubuntu3.10结果
file_uploads =在的
下面是我的android code
RequestConfig配置= RequestConfig.custom（）
.setConnectTimeout（30000）
.setConnectionRequestTimeout（30000）
.setSocketTimeout（30000）
.setProxy（getProxy（））
。建立（）;CloseableHttpClient客户端= HttpClientBuilder.create（）
.setDefaultRequestConfig（配置）
。建立（）;HttpPost后=新HttpPost（http://example.com）;尝试{ JSONObject的根=新的JSONObject（）;
root.put（ID，身份证）; 如果（mSettings！= NULL）{
root.put（设置，SettingsJsonRequestHelper.getSettingsJson（mSettings））;
} 。MultipartEntityBuilder建设者= MultipartEntityBuilder.create（）setMode（HttpMultipartMode.BROWSER_COMPATIBLE）; 文件截图= getScreenshotFile（）;
如果（screenshot.exists（））{
builder.addPart（屏幕截图，新FileBody（截图，ContentType.create（图像/ JPEG）））;
} builder.addTextBody（数据，root.toString（），ContentType.create（文/ JSON，Charset.forName（UTF-8）））; builder.setCharset（MIME.UTF8_CHARSET）;
post.setEntity（builder.build（））;
}赶上（JSONException E）{
。Logger.getInstance（）日志（E）;
}尝试{
HTT presponse响应= client.execute（岗位）;
如果（response.getStatusLine（）的getStatus code（）== HttpStatus.SC_OK）{
mResponse.setResponse（response.getEntity（）的getContent（））;
}其他{
。Logger.getInstance（）日志（回应错误code。+ response.getStatusLine（）的getStatus code（））;
}
}赶上（ClientProtocolException E）{
。Logger.getInstance（）日志（E）;
}赶上（IOException异常五）{
。Logger.getInstance（）日志（E）;
}
解决方案
不知道该方法使用的是和你没有包括你的服务器端处理文件。错误可能来自任何一个。不过，试试这个。我首先向它发送一个文件路径通过PARAMS并将其命名为textFileName。
@覆盖
保护字符串doInBackground（字符串... PARAMS）{
// 文件路径
串textFileName =参数[0];
字符串消息=这是一个多岗;
字符串结果=; //设置服务器端脚本文件来处理它
HttpPost后=新HttpPost（http://10.0.2.2/test/upload_file_test.php）;
档案文件=新的文件（textFileName）; //图像文件和文本添加到建设者
MultipartEntityBuilder建设者= MultipartEntityBuilder.create（）;
builder.setMode（HttpMultipartMode.BROWSER_COMPATIBLE）;
builder.addBinaryBody（uploaded_file，文件，ContentType.DEFAULT_BINARY，textFileName）;
builder.addTextBody（文字，邮件，ContentType.DEFAULT_BINARY）; //括在一个实体，执行，结果得到
HttpEntity实体= builder.build（）;
post.setEntity（实体）;
HttpClient的客户端=新DefaultHttpClient（）;
尝试{
HTT presponse响应= client.execute（岗位）;
读者的BufferedReader =新的BufferedReader（新的InputStreamReader（
。response.getEntity（）的getContent（），UTF-8））;
串sResponse;
StringBuilder的S =新的StringBuilder（）; 而（（sResponse = reader.readLine（））！= NULL）{
S = s.append（sResponse）;
}
的System.out.println（回应：+ S）; }赶上（ClientProtocolException E）{
// TODO自动生成catch块
e.printStackTrace（）;
}赶上（IOException异常五）{
// TODO自动生成catch块
e.printStackTrace（）;
}
返回消息;
}
服务器端的PHP是这样的：
＆LT; PHP
$ target_path1 =上传/;
/ *原始文件名添加到我们的目标路径。
结果是上传/ filename.extension* /
$状态=;
如果（使用isset（$ _ FILES [uploaded_file]））{回声文件存在！//如果（使用isset（$ _ POST [文字]））{
//回声的消息文件存在！$ _ POST [文字]。
//}$ target_path1 = $ target_path1。基本名（$ _FILES ['uploaded_file'] ['名']）;如果（move_uploaded_file（$ _ FILES ['uploaded_file'] ['tmp_name的值']，$ target_path1））{
$状态=第一个文件。基本名（$ _FILES ['uploaded_file'] ['名']）。
已上传。
}
其他{
$状态=有上传文件的错误，请重试！
$状态=文件名。基本名（$ _FILES ['uploaded_file'] ['名']）;
$状态=target_path：。$ target_path1;
}}其他{回声中的文件目录中没有;
}$阵列[身份] =状态：$地位;
$ JSON_OBJECT = json_en code（$数组）;
回声$ JSON_OBJECT;？＆GT;
I'm trying to send post request from android application to server. In this request I want to send some text data (json) and picture.
But I can't get this data in server. Variables $_FILES, $_POST and even php://input is empty. But data is really transferred to server, because in $_SERVER I can find this:
[REQUEST_METHOD] => POST
[CONTENT_TYPE] => multipart/form-data; boundary=Jq7oHbmwRy8793I27R3bjnmZv9OQ_Ykn8po6aNBj; charset=UTF-8
[CONTENT_LENGTH] => 53228
What is the problem can be with this?
server is nginx 1.1
PHP Version 5.3.6-13ubuntu3.10
file_uploads = On
Here is my android code
RequestConfig config = RequestConfig.custom()
.setConnectTimeout(30000)
.setConnectionRequestTimeout(30000)
.setSocketTimeout(30000)
.setProxy(getProxy())
.build();
CloseableHttpClient client = HttpClientBuilder.create()
.setDefaultRequestConfig(config)
.build();
HttpPost post = new HttpPost("http://example.com");
try {
JSONObject root = new JSONObject();
root.put("id", id);
if (mSettings != null) {
root.put("settings", SettingsJsonRequestHelper.getSettingsJson(mSettings));
}
MultipartEntityBuilder builder = MultipartEntityBuilder.create().setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
File screenshot = getScreenshotFile();
if (screenshot.exists()) {
builder.addPart("screenshot", new FileBody(screenshot, ContentType.create("image/jpeg")));
}
builder.addTextBody("data", root.toString(), ContentType.create("text/json", Charset.forName("UTF-8")));
builder.setCharset(MIME.UTF8_CHARSET);
post.setEntity(builder.build());
} catch (JSONException e) {
Logger.getInstance().log(e);
}
try {
HttpResponse response = client.execute(post);
if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
mResponse.setResponse(response.getEntity().getContent());
} else {
Logger.getInstance().log("response error. Code " + response.getStatusLine().getStatusCode());
}
} catch (ClientProtocolException e) {
Logger.getInstance().log(e);
} catch (IOException e) {
Logger.getInstance().log(e);
}
解决方案
Not sure of the method you are using and you did not include your server side processing file. Error may be from either one. But try this. I first send it a file path through the params and named it 'textFileName'.
@Override
protected String doInBackground(String... params) {
// File path
String textFileName = params[0];
String message = "This is a multipart post";
String result =" ";
//Set up server side script file to process it
HttpPost post = new HttpPost("http://10.0.2.2/test/upload_file_test.php");
File file = new File(textFileName);
//add image file and text to builder
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
builder.addBinaryBody("uploaded_file", file, ContentType.DEFAULT_BINARY, textFileName);
builder.addTextBody("text", message, ContentType.DEFAULT_BINARY);
//enclose in an entity and execute, get result
HttpEntity entity = builder.build();
post.setEntity(entity);
HttpClient client = new DefaultHttpClient();
try {
HttpResponse response = client.execute(post);
BufferedReader reader = new BufferedReader(new InputStreamReader(
response.getEntity().getContent(), "UTF-8"));
String sResponse;
StringBuilder s = new StringBuilder();
while ((sResponse = reader.readLine()) != null) {
s = s.append(sResponse);
}
System.out.println("Response: " + s);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return message;
}
Server side php looks like:
<?php
$target_path1 = "uploads/";
/* Add the original filename to our target path.
Result is "uploads/filename.extension" */
$status = "";
if(isset($_FILES["uploaded_file"])){
echo "Files exists!!";
// if(isset($_POST["text"])){
// echo "The message files exists! ".$_POST["text"];
// }
$target_path1 = $target_path1 . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path1)) {
$status= "The first file ". basename( $_FILES['uploaded_file']['name']).
" has been uploaded.";
}
else{
$status= "There was an error uploading the file, please try again!";
$status.= "filename: " . basename( $_FILES['uploaded_file']['name']);
$status.= "target_path: " .$target_path1;
}
}else{
echo "Nothing in files directory";
}
$array["status"] = "status: ".$status;
$json_object = json_encode($array);
echo $json_object;
?>
