我尝试使用改造将多个图像发送到服务器 我正在做的是发送RequestBody的地图,这是我的代码
@Multipart
@POST("imageuload")
Call<ResponseBody> postImage(@PartMap Map<String, RequestBody> files );
和我的活动
Map<String, RequestBody> filestosend = new HashMap<>();
for (int pos = 0; pos < files.size(); pos++) {
RequestBody requestBody = RequestBody.create(MediaType.parse("image/*"), files.get(pos));
filestosend.put("photo_" + String.valueOf(pos + 1), requestBody);
}
Call<ResponseBody> call = apiSerice.postImage(filestosend);
call.enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
if (response.isSuccessful()) {
try {
Toast.makeText(getBaseContext(),response.body().string(),Toast.LENGTH_LONG).show();
} catch (IOException e) {
e.printStackTrace();
}
}else {
try {
AlertDialog.Builder alert = new AlertDialog.Builder(MainActivity.this);
alert.setMessage(response.errorBody().string());
alert.show();
} catch (IOException e) {
e.printStackTrace();
}
}
}
@Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
t.printStackTrace();
}
});
当我想测试我得到的内容时,它会从服务器返回一个空的响应,我的回复中什么都没有。
echo file_get_contents('php://input');
我甚至只用一个请求主体进行测试
RequestBody test = RequestBody.create(MediaType.parse("text/plain"), "test");
Call<ResponseBody> call = apiSerice.postImage(test);
但我在回复时仍然得到一个空洞的回应 我将不胜感激任何帮助或评论

可以通过$_FILES
在PHP中访问分段上传。关于php://input
,PHP manual有以下说法:
php://输入不适用于enctype =“multipart / form-data”。
一个完整的工作示例(减去正确的端点URL,硬编码字节数组):
public class Sample {
interface SampleService {
@Multipart
@POST("/test.php")
Call<ResponseBody> postImage(@Part List<MultipartBody.Part> files);
}
public static void main(String[] args) throws IOException {
Retrofit retrofit = new Retrofit.Builder().baseUrl("http://...").build();
SampleService service = retrofit.create(SampleService.class);
RequestBody file1 = RequestBody.create(MediaType.parse("image/jpeg"), new byte[]{0x00});
MultipartBody.Part part1 = MultipartBody.Part.createFormData("A kitten", "Kitten.jpg", file1);
RequestBody file2 = RequestBody.create(MediaType.parse("image/jpeg"), new byte[]{0x00});
MultipartBody.Part part2 = MultipartBody.Part.createFormData("Another kitten", "Kitten2.jpg", file2);
System.out.println(service.postImage(Arrays.asList(part1, part2)).execute().body().string());
}
}
服务器代码:
<?php var_dump($_FILES); ?>
客户输出:
array(2) {
["A_kitten"]=>
array(5) {
["name"]=>
string(10) "Kitten.jpg"
["type"]=>
string(10) "image/jpeg"
["tmp_name"]=>
string(14) "/tmp/phpml5PIP"
["error"]=>
int(0)
["size"]=>
int(1)
}
["Another_kitten"]=>
array(5) {
["name"]=>
string(11) "Kitten2.jpg"
["type"]=>
string(10) "image/jpeg"
["tmp_name"]=>
string(14) "/tmp/phpzhgXm0"
["error"]=>
int(0)
["size"]=>
int(1)
}
}
