从android上传图片文件到laravel-api

Question

我无法理解如何将图像文件从我的android设备上传到带有POST数据的Laravel API，我已经使用android-asynchronous-http-client向API发送了一些文本数据，但它无法使用图像文件。API端工作良好我使用POSTMAN测试了它，但在android设备status code: 500 Internal Server Error上出现错误

RequestParams ComplaintsDataRequestParams = new RequestParams();
ComplaintsDataRequestParams.put("Complaint_Subject", complaintsSubject.getText().toString());
ComplaintsDataRequestParams.put("Complaint_Details", complaintsDetails.getText().toString());
ComplaintsDataRequestParams.put("Complaint_Address", complaintAddress.getText().toString());
ComplaintsDataRequestParams.put("Username", HomeActivity.home_username);
ComplaintsDataRequestParams.put("Complainant_CNIC", HomeActivity.user_cnic);
ComplaintsDataRequestParams.put("Complaint_id", uniqueComplaintID);
ComplaintsDataRequestParams.put("User_Location", user_complete_address + "-" + lat + "," + lng);
if (ImageEvidence1 != null) {
evidenceID1 = uniqueComplaintID + "-" + System.currentTimeMillis();
ComplaintsDataRequestParams.put("Evidence_ID1", "YES");
ComplaintsDataRequestParams.put("Evidence_ID1_name", evidenceID1);
ComplaintsDataRequestParams.put("Evidence_ID1_data", ImageEvidence1);
}
if (ImageEvidence2 != null) {
evidenceID2 = uniqueComplaintID + "-" + System.currentTimeMillis();
ComplaintsDataRequestParams.put("Evidence_ID2", "YES");
ComplaintsDataRequestParams.put("Evidence_ID2_name", evidenceID2);
ComplaintsDataRequestParams.put("Evidence_ID2_data", ImageEvidence2);
}
if (ImageEvidence3 != null) {
evidenceID3 = uniqueComplaintID + "-" + System.currentTimeMillis();
ComplaintsDataRequestParams.put("Evidence_ID3", "YES");
ComplaintsDataRequestParams.put("Evidence_ID3_name", evidenceID3);
ComplaintsDataRequestParams.put("Evidence_ID3_data", ImageEvidence3);
}

Complaints_REST_API_Client.POST("?action=store", ComplaintsDataRequestParams, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] response) {
// called when response HTTP status is "200 OK"
complaint_confirmation();
Log.d("newComplaintActivity", "statusCode " + statusCode);
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[] errorResponse, Throwable error) {
// called when response HTTP status is "4XX" (eg. 401, 403, 404)
submittingComplaint.dismiss();
Log.d("newComplaintActivity", "statusCode " + statusCode);
Toast.makeText(getContext(), "Exception: " + error.getMessage(), Toast.LENGTH_SHORT).show();
}
});

ImageEvidence是Uri类型的变量，用于imageView.setImageURI(ImageEvidence)和evidenceID只是图像文件的名称。

'eivdence_image' => $request->file('Evidence_ID3_data')->store('public/evidences'),
'complaint_id' => $request->input('Complaint_id')
]);

请告诉我应该使用哪个库来发送图像文件和POST数据。

Answer 1

我用一个非常简单的快捷方法解决了我的问题

因为我在API端请求文件，但我正在发送Uri，即ImageEvidence1。所以简单的破解方法是，我得到URI的绝对路径，并将其放入文件中，然后

File file = new File(new URI(ImageEvidence1.getPath()));
ComplaintsDataRequestParams.put("Evidence_ID3_data", file);

就是这样。
