用bash读取文本文件并发送curl查询

Question

I have a text file containing data to classify:

facture
iphone
comment acceder

I have a bash script reading my text file line per line, and sending each line using curl to a classifier written in Python 3.4 and running in a Docker container. Here is the code of the script:

old_IFS=$IFS
IFS=$'\n'
for line in $(cat file.txt) do
    echo $line
    curl -d q=$line localhost:8099/v2
    echo $'\n'
    sleep 1
done
IFS=$old_IFS

localhost:8099/v2 is the adress of the Docker container. For each query, the classifier prints the probabilities of belonging to the defined classes (3 classes in our case: assistance, actu and boutique).

Let's have a look at the output of the command

curl -d q=facture localhost:8099/v2

{"classes": ["assistance"], "levels": {"assistance": 0.915, "boutique": 0.085, "actu": 0.0}}

However, when I'm running the script, I have this output:

facture
{"classes": ["boutique", "actu", "assistance"], "levels": {"boutique": 0.333, "actu": 0.333, "assistance": 0.333}}

iphone
{"classes": ["boutique", "actu", "assistance"], "levels": {"boutique": 0.333, "actu": 0.333, "assistance": 0.333}}

{"classes": ["assistance"], "levels": {"assistance": 0.886, "boutique": 0.113, "actu": 0.0}}

The probabilities are not correct, which leads me to think that the query is not well read by the script. This assumption is contradicted by the fact that the line is correctly printed by the script. I first thought of an encoding problem, but all my files are using utf8, and so does the terminal.

So my question is, is my script doing something wrong when reading the content of the file ?

Answer 1

Try : q="facture" ?

I believe that your console needs to assume a string as a key. As it doesn't recognize the pattern, it searches for all by default ?

Answer 2

I guess maybe is your file.txt is not unix format, try execute

dos2unix file.txt

first
