TIKA

Tika下载

1. server.jar

   http://tika.apache.org/download.html
   java -jar tika-server-1.17.jar
   

   下载server版，需要java运行环境。注：JAVA9默认缺少server运行所需要的xml.bind包，需要另行解决，JAVA8无问题。

2. docker

   docker pull logicalspark/docker-tikaserver # only on initial download/update
   docker run --rm -p 9998:9998 logicalspark/docker-tikaserver
   

3. app.jar

   app也有server模式，但他并非HTPP协议，所以无法使用curl调试。
   

4. maven

Docker Server

1. 测试服务器

   curl -X GET http://localhost:9998/tika 
   

2. 获取meta

   curl -T test.pdf http://localhost:9998/meta --header "Accept: application/json"
   

3. 获取文档内容

   curl -X PUT --data-binary @test.pdf http://localhost:9998/tika --header "Content-Type: text/pdf"
   curl -T test.pdf http://localhost:9998/tika --header "Accept: text/html" # 返回html，带标签，可不带header
   

Go Implement

var tikaServerUrl = "http://localhost:9998/"
func putRequest(url, filename string) (string, error) {
	file, err := os.Open(filename)
	if err != nil {
		return "", err
	}
	req, err := http.NewRequest(http.MethodPut, url, file)
	client := &http.Client{}
	response, err := client.Do(req)
	if err != nil {
		return "", err
	}
	defer response.Body.Close()
	b, _ := ioutil.ReadAll(response.Body)
	return string(b), nil
}
