我正在嘗試在 JSF 應(yīng)用程序中實(shí)現(xiàn) Cloudinary 上傳。根據(jù) Cloudinary 網(wǎng)站上的說明，我正在使用此依賴項(xiàng)：<dependency> <groupId>com.cloudinary</groupId> <artifactId>cloudinary-http44</artifactId> <version>1.19.0</version></dependency>我有一個(gè)用于上傳的類：package com.github.cvetan.bookstore.util;import com.cloudinary.*;import com.cloudinary.utils.ObjectUtils;import java.io.IOException;import java.util.HashMap;import java.util.Map;/** * * @author cvetan */public class CloudinaryFacade { private final static Map<Object, Object> CONFIG = new HashMap<>(); static { CONFIG.put("cloud_name", "cvetan"); CONFIG.put("api_key", "***"); CONFIG.put("api_secret", "***"); } public static String upload(byte[] file) throws IOException { Cloudinary cloudinary = new Cloudinary(CONFIG); Map result = cloudinary.uploader().upload(file, ObjectUtils.emptyMap()); return (String) result.get("url"); }}但是當(dāng)我嘗試時(shí)，會(huì)拋出下面的異常：Invalid Signature 6e527a754f1f6fd84df0bd4c092df881c0ddc65f. String to sign - 'timestamp=1533653472'.任何幫助將不勝感激。謝謝。

當(dāng)年話下
TA貢獻(xiàn)1890條經(jīng)驗(yàn) 獲得超9個(gè)贊
我已經(jīng)設(shè)法讓它工作。我最終將上傳的文件內(nèi)容從 PrimeFaces 復(fù)制uploadedFile到一個(gè)臨時(shí)文件中，并將該文件發(fā)送到 Cloudinary 上傳。
托管 bean 類方法（上傳處理程序）：
public String upload() {
try {
File uploadedFile = File.createTempFile("image", ".tmp");
InputStream content = file.getInputstream();
Files.copy(content, uploadedFile.toPath(), StandardCopyOption.REPLACE_EXISTING);
String filename = CloudinaryFacade.upload(uploadedFile);
return Redirector.redirectWithMessage(filename, FacesMessage.SEVERITY_INFO, null);
} catch (IOException ex) {
return Redirector.redirectWithMessage(ex.getMessage(), FacesMessage.SEVERITY_ERROR, null);
}
}
云端上傳方式：
public static String upload(File file) throws IOException {
Cloudinary cloudinary = new Cloudinary(CONFIG);
Map<Object, Object> parameters = new HashMap<>();
parameters.put("public_id", "Bookstore/Authors/Images/vejder");
Map result = cloudinary.uploader().upload(file, parameters);
return (String) result.get("url");
}
謝謝你。
