Use Get File (or) List/FetchFile processors to fetch the file.

then use

1.Split Text Processor(if you are having each url for a line) with line split count as 1

If your file having 4 lines then after split text processor will give seperate flowfiles for each line.

Example:-

Input 1 file(having 4 lines) and output will be 4 flow files(each line as seperate flowfile)

2.Extract Text processor to extract the url's to attributes for the flowfile. According to your file content size you need to change the Maximum Buffer size property and i'm extracting all the contents of the flowfile to url attribute by using regex .*

url

(.*) //extract the whole content of the flowfile add the content to the flow file url attribute

then use

3.invoke http processor with ${url}

We are going to use the extracted url attribute from extract text processor in invoke http processor.

The extracted url attribute will be changed dynamically according to the flowfile content.

Flow:-

1.Get File
2.Split Text
3.Extract Text
4.Invoke HTTP
