通过纯Nginx实现一个简单的文件上传功能

需求想要上传文件到服务器，内部使用访问也不多，但是上传接口没有，又不想额外配置一个文件服务器，通过查阅资料发现Nginx自带文件上传功能。

1. 检查当前nginx是否包含 dav 模块

bash 复制代码

nginx -V 2>&1 | findstr "dav"

输入该命令，检查，如果有的话，就可以使用了。

2. 配置上传接口

bash 复制代码

    location /eventFileUpload {
        # 设置上传文件大小限制为 100M
        client_max_body_size 100M;
    
        # 指定文件保存路径（注意使用正斜杠：我用的是windows服务器）
        alias E:/xxx/xxx/xxx;
    
        # 开启目录浏览，方便查看已上传的文件
        autoindex on;
    
        # 启用 WebDAV 功能
        dav_methods PUT DELETE MKCOL COPY MOVE;
    
        # 允许创建多级目录
        create_full_put_path on; 
     }

3. 调用上传

java 复制代码

 public static void main(String[] args) {
        try {
            // File path to upload
            String filePath = "D:\\1.txt";
            File file = new File(filePath);
            
            if (!file.exists()) {
                System.out.println("File does not exist: " + filePath);
                return;
            }
            
            // Upload URL 注意这里哦，eventFileUpload 为nginx 配置的访问url。后面为文件地址，要放进来的服务器的文件地址，要加到这里，因为body只传了文件流，没有指定上传到哪个路径，需要在这里指定哦
            String uploadUrl = "http://xxx/xxx/xxx/eventFileUpload/222/1.txt";
            
            // Create OkHttp client
            OkHttpClient client = new OkHttpClient();
            
            // Create request body with file content
            okhttp3.RequestBody requestBody = okhttp3.RequestBody.create(
                file, 
                MediaType.parse("application/octet-stream")
            );
            
            // Build PUT request
            Request request = new Request.Builder()
                .url(uploadUrl)
                .put(requestBody)
                .build();
            
            // Execute request
            System.out.println("Uploading file: " + filePath);
            System.out.println("To URL: " + uploadUrl);
            
            try (Response response = client.newCall(request).execute()) {
                if (response.isSuccessful()) {
                    System.out.println("Upload successful!");
                    System.out.println("Response code: " + response.code());
                    if (response.body() != null) {
                        System.out.println("Response body: " + response.body().string());
                    }
                } else {
                    System.out.println("Upload failed!");
                    System.out.println("Response code: " + response.code());
                    System.out.println("Response message: " + response.message());
                    if (response.body() != null) {
                        System.out.println("Response body: " + response.body().string());
                    }
                }
            }
        } catch (Exception e) {
            System.err.println("Error during file upload: " + e.getMessage());
            e.printStackTrace();
        }
    }
