在Volley Request中将图像与其他参数作为多部分发送 [英] Send Images as Multipart with Other Params in Volley Request
问题描述
我正在使用截击请求向服务器发送一个带有两个参数的请求,并且工作正常.现在,要求已更改,我需要将至少一个图像或最多3个图像以及其他两个参数发送到服务器.图像必须作为多部分发送.我有以下代码用于从图库中获取图像并将其文件路径存储在列表中.
I was sending a request to the server with two parameters using volley request and it was working fine. Now the requirement has changed and I need to send at least one image or maximum 3 images to the server along with the other two parameters. The image must be sent as multi-part. I have following code for Getting image from gallery and storing their file paths in the list.
List<String> imagePathList = imageFilePaths;
List<MultipartBody.Part> partMap = new ArrayList<>();
for (int i = 0; i < imagePathList.size(); i++) {
Uri fileUri = Uri.parse(imagePathList.get(i));
RequestBody requestFile = RequestBody.create(
MediaType.parse(getMimeTypee(FileUtils.getFile(getContext(), fileUri).getAbsolutePath())),
FileUtils.getFile(getContext(), fileUri)
);
MultipartBody.Part body = MultipartBody.Part.createFormData("court_image[" + i + "]", FileUtils.getFile(getContext(), fileUri).getName(), requestFile);
partMap.add(body);
}
imageFilePaths
是ArrayList
的位置.服务器将接收court_image[0]
,court_image[1]
等图像,具体取决于我在ArrayList
中具有多少图像路径.
Where imageFilePaths
is an ArrayList
. The server will receive images like court_image[0]
, court_image[1]
and so on, depends on how many image paths I have in ArrayList
.
齐射要求在这里
RequestQueue queue = Volley.newRequestQueue(getContext());
StringRequest postRequest = new StringRequest(Request.Method.POST, url1,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Toast.makeText(mBaseAppCompatActivity, "Success", Toast.LENGTH_SHORT).show();
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
}
) {
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
String token = getToken();
params.put("Authorization", "Bearer " + token);
params.put("Content-Type", "multipart/form-data");
return params;
}
@Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("terms", "true");
params.put("phone", "phoneNo");
return params;
}
};
queue.add(postRequest);
现在事情变得很复杂了,我可以从图库中获取图像并将其路径存储在ArrayList
中,但是我不知道如何通过多部分排球请求中的零件数据.请帮忙.
Now the thing is as I am new to the multi-part thing, with the help I am able to get the image from gallery and storing their path in ArrayList
but I don't know how to pass the multi-part data in this volley request. Please help.
推荐答案
尽管这是一个老问题,但我认为我应该在此处发布答案,因为我遇到了同样的问题,可以设法解决.
Though this is an old question, I thought I should post my answer here as I was having the same problem and could manage to solve that.
为了上载图像以及其他一些参数,我使用了齐射.但是,我发现了原始齐射库的包装器,该包装器更易于集成到多部分请求中.因此,我在build.gradle
文件中添加了以下库.
For uploading the image along with some other parameters, I used volley. However, I found a wrapper of the original volley library which is easier to integrate for multi-part requests. Hence I added the following library in the build.gradle
file.
dependencies {
compile 'dev.dworks.libs:volleyplus:+'
}
我从build.gradle
中删除了原始的凌空库,并改用了上述库,该库可以处理具有类似集成技术的多部分请求和常规请求.
I removed the original volley library from my build.gradle
and used the above library instead which can handle both multi-part and normal requests having similar integration technique.
然后,我只需要编写下面的类来处理POST请求操作.
Then I just had to write the following class which handles the POST request operation.
public class POSTMediasTask {
public void uploadMedia(final Context context, String filePath) {
String url = getUrlForPOSTMedia(); // This is a dummy function which returns the POST url for you
SimpleMultiPartRequest multiPartRequestWithParams = new SimpleMultiPartRequest(Request.Method.POST, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Log.d("Response", response);
// TODO: Do something on success
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// TODO: Handle your error here
}
});
// Add the file here
multiPartRequestWithParams.addFile("file", filePath);
// Add the params here
multiPartRequestWithParams.addStringParam("terms", "SomeTerms");
multiPartRequestWithParams.addStringParam("phone", "85050055055");
RequestQueue queue = Volley.newRequestQueue(context);
queue.add(multiPartRequestWithParams);
}
}
现在执行如下任务.
new POSTMediasTask().uploadMedia(context, mediaPath);
您可以使用此库一次上传一个文件.但是,我可以通过启动多个任务来设法上传多个文件.
You can upload one file at a time using this library. However, I could manage to upload multiple files, just by initiating multiple tasks.
