使用改造2将图片上传到服务器 [英] Upload picture to server using retrofit 2
本文介绍了使用改造2将图片上传到服务器的处理方法，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
首先让我们看一下代码:
First of all lets look to the code:
public interface ApiInterface {
@Multipart
@POST("my/files/photo/")
Call<FileUploadResponse> uploadPhoto(@Header("authorization") String auth,
@Part MultipartBody.Part file,
@Part("file-type") RequestBody fileType);
}
我这样称呼这个接口:
RequestBody body = RequestBody.create(MediaType
.parse(getContentResolver().getType(fileUri)), file);
MultipartBody.Part avatarBody = MultipartBody.Part
.createFormData(data, file.getName(), body);
RequestBody fileType = RequestBody.create(
MediaType.parse("text/plain"), "profile");
client.uploadPhoto(getToken(), avatarBody, fileType);
我从服务器收到响应，提示未提供文件类型".如果我像这样更改uploadPhoto函数上的文件和文件类型的位置:
From server i'm getting response that "File type not provided". If i change places of file and filetype on uploadPhoto function like this:
@Multipart
@POST("my/files/photo/")
Call<FileUploadResponse> uploadPhoto(@Header("authorization") String auth,
@Part("file-type") RequestBody fileType
@Part MultipartBody.Part file);
我收到响应文件未提供". 我已经用自己写在JS上的代码检查了服务器:
I'm getting response "File not provided". I've checked server with my own code written on JS:
<!DOCTYPE html>
<script language="JavaScript" type="text/javascript" src="C://Users/User/Downloads/jquery-3.2.1.min.js"></script>
<form action="">
<input type="text" name="authorize" id="authorize">
<br>
<input type="file" name="photo" accept="image/*" id="filechooser" onchange="onFileChange(this)" >
<br>
<input value="profile" type="text" name="file-type" id="type">
<br>
<input type="button" onclick="uploadFile()">
</form>
<script>
var blobFile;
function onFileChange(ss) {
blobFile = ss.files[0];
alert(blobFile);
}
function uploadFile() {
var storedJWT = $('#authorize').val();
var fileType = $('#type').val();
var formData = new FormData();
formData.append("file-type", fileType);
formData.append("photo", blobFile);
console.log(storedJWT);
$.ajax({
url: "url",
type: "POST",
data: formData,
headers: {
authorization: storedJWT
},
processData: false,
contentType: false,
success: function(response) {
console.log(response);
},
error: function(jqXHR, textStatus, errorMessage) {
console.log(errorMessage);
}
});
}</script>
一切正常. JS上的脚本生成请求，如下所示:
everything working fine. Script on JS generating request like this:
Accept:*/*
Accept-Encoding:gzip, deflate
Accept-Language:en-US,en;q=0.8
authorization:JWT token
Connection:keep-alive
Content-Length:67601
Content-Type:multipart/form-data; boundary=----
WebKitFormBoundary3MtpMA70hG41luF1
Host:localhost
------WebKitFormBoundary3MtpMA70hG41luF1
Content-Disposition: form-data; name="file-type"
profile
------WebKitFormBoundary3MtpMA70hG41luF1
Content-Disposition: form-data; name="photo"; filename="1231231313.jpg"
Content-Type: image/jpeg
------WebKitFormBoundary3MtpMA70hG41luF1--
，改装请求为:
Content-Type: multipart/form-data; boundary=238182ad-d99c-4d44-9ba6-7d178a14b2e9
Content-Length: 59776
authorization: JWT token
--238182ad-d99c-4d44-9ba6-7d178a14b2e9
Content-Disposition: form-data; name="photo"; filename="1502703422332.jpg"
Content-Type: image/jpeg
Content-Length: 59369
//bytes
--238182ad-d99c-4d44-9ba6-7d178a14b2e9
Content-Disposition: form-data; name="file-type"
Content-Transfer-Encoding: binary
Content-Type: text/plain; charset=utf-8
Content-Length: 7
profile
--238182ad-d99c-4d44-9ba6-7d178a14b2e9--
我不知道哪里可能出错...
I can't understand where can be error...
推荐答案
经过多次搜索，我发现服务器无法处理
After many search I found that server not handling headers like
Content-Transfer-Encoding: binary
Content-Type: text/plain; charset=utf-8
，我必须从我的请求中删除这些标头.解决方案是在我的API接口中创建上传函数，如下所示:
and i have to remove these headers from my request. And the solution is creating upload function in my API Interface like this:
@POST("my/files/photo/")
Call<FileUploadResponse> uploadPhoto(@Header("Content-Type") String contentType,
@Header("Authorization") String auth,
@Body MultipartBody body);
并按以下方式调用此函数:
and call this function like:
ApiClient.ApiInterface client = ApiClient.getClient();
File file = new File(getPathFromUri(fileUri));
RequestBody fileBody = RequestBody.create(MediaType.parse(getContentResolver().getType(fileUri)), file);
MultipartBody body = new MultipartBody.Builder().addFormDataPart("file-type", "profile")
.addFormDataPart("photo", "image.png", fileBody)
.build();
client.uploadPhoto("multipart/form-data; boundary=" + body.boundary(),
PrefManager.getInstance().getToken(), body);
结果，我在下面收到请求:
As result I get request below:
Content-Type: multipart/form-data; boundary=27ec8d66-d29d-48aa-a2fe-08c6664b10c7
Content-Length: 56412
Authorization: JWT token
--27ec8d66-d29d-48aa-a2fe-08c6664b10c7
Content-Disposition: form-data; name="file-type"
Content-Length: 7
profile
--27ec8d66-d29d-48aa-a2fe-08c6664b10c7
Content-Disposition: form-data; name="photo"; filename="image.png"
Content-Type: image/jpeg
Content-Length: 56089
/* bytes */
--27ec8d66-d29d-48aa-a2fe-08c6664b10c7--
它工作正常.
