Convert Python request with image to cURL - java

I found this example of a API request. Unfortunately I didn't find any other example how to upload an image to the API.
As I'm not familiar with Python I'm trying to understand how to do the same in a cURL command.
import requests
auth_headers = {
'app_id': 'your_app_id',
'app_key': 'your_app_key'
}
url = 'https://XXXXXXX'
files = {
'source': open('media/test.jpg')
}
data = {
'timeout': 60
}
response = requests.post(url, files=files, data=data, headers=auth_headers)
I tried to convert it by trying out a cURL to python converter, but I don't know how to build it with the files.
In the end I want to do the request in JAVA, but I think if I would know the request in cURL I can figure it out.
Hope anyone can help me with that.


This will do it:
#!/bin/bash
args=(
-H 'app_id: your_app_id'
-H 'app_key: your_app_key'
-F 'source=#/path/to/file'
-F 'timeout=60'
'http://httpbin.org/post'
)
curl "${args[#]}"
or, as a one-liner:
curl -H 'app_id: your_app_id' -H 'app_key: your_app_key' -F 'source=#/path/to/file' -F 'timeout=60' 'http://httpbin.org/post'
Use -H to specify header fields (repeat for every field) and -F to specify form fields - either as key=value pairs, or filename=#path pairs. When -F is used, POST method is the default, and Content-Type is multipart/form-data (but that too can be overridden).

get a pagingobject in http response requested over curl

Hello people i have a question about how to get JSON pagingObject in my response with a http curl get (curl running on jokto-linux-system).
i wanted to get a special page over the parameter $offset=0 and $limit=0.
But i dont know where to put the parameter to get on the right page of the serviceressource. I get all the ressources back but i need to see how much pages are used also i didnt see this too.
So my basic problem is the visibility and changing of the parameter $offset and $limit of the pagingObject of an Service/Ressource with amount of Ressourceelements.
Thank you very much for evry answer
This my basic "GET" i try: curl -i http://127.0.0.1:80/service/ressource/Elementuri
Tried to get an the object over header: curl -X GET -H "$offset" -H "$limit" http://127.0.0.1:80/service/ressource/elementuri
I tried it to set after the uri: curl -X GET http://127.0.0.1:80/service/ressource/elementuri?$offset=0&$limit=1

Dollar sign is probably not necessary.
curl http://127.0.0.1:80/service/ressource/elementuri?limit=2&offset=2

how can i call web services with curl with json param?

I'm programming in Java.
I developed a test web service in which I pass a random json and the service returns me hello
Here the web service code:
#Path("test")
#GET
#Consumes(MediaType.APPLICATION_JSON)
public String test(#HeaderParam("token") String token, #QueryParam("array")String array)
{
return "hello";
}
I call the service with curl
curl -v -H 'token:aaaa' 'http://140.145.1.2/clayapi/restservices/test?array=[{"name":"george","lastname":"ronney"}]';
message of error:
curl: (3) [globbing] illegal character in range specification at pos 60
I tried to add -g but it doesn't work .. how should I do?

Use -G along with --data-urlencode:
curl -v -G 'http://example.org' \
-H 'header:value' \
--data-urlencode 'array=[{"name":"george","lastname":"ronney"}]'
From the documentation:
-G, --get
When used, this option will make all data specified with -d, --data, --data-binary or --data-urlencode to be used in an HTTP GET request instead of the POST request that otherwise would be used. The data will be appended to the URL with a ? separator. [...]
--data-urlencode <data>
(HTTP) This posts data, similar to the other -d, --data options with the exception that this performs URL-encoding. [...]

To accept -d #json , How put method should be written in rest api

In PUT rest call , Using curl I would like to use -d option , what should be method signature . I am using java.
curl -X PUT -u testUser 'http://hostname:port/method' -d #test.json -H "Content-Type: application/json"
This should be my curl when I fire .
I have written a method signature which accepts string as input
#PUT #Path ("/test")
#Produces("application/json")
public Response method(String input) throws Exception {...}
When I run above command , Having above method signature is throwing error .
Error processing command: java.lang.NullPointerException
String input needs data in json format .
{
"name" : "test",
"host" : "10.xx.xx.xx",
"port" : 22
.
.
} //around 15 values
having these in a single url like this
"http://hostname:port/method?name=test&host=10.xx.xx.xx&port=22........."
makes url grow pretty long but its working though.
I would like to use -d option to send json input through a file.
What should be the method signature for curl to work with -d #test.json in java ?
--Thanks in Advance.

Hyperledger Composer + loopback-datasource-juggler + Java: Encoding Problems

I developed a Business Network Definition with Hyperledger Composer, deployed it on a Hyperledger Fabric example-chain (running locally on a VirtualBox-installation of Ubuntu with Docker-containers) and started Composer's REST-server with composer-rest-server (and options -c [cardname] -n always -w true). Then I played a bit in the browser and all is working fine.
Now comes the problematic bit: I want to write a Java-program interacting with this REST API and somehow the API seems unable to parse my Java-sent requests. I copied the JSON-string that Java produces to the browser, ran it there and it worked fine. But if I send it programmatically I get the error (see at the end).
This is what I send through the browser
{"cId":"C_ID7","cDomain":"example.com"}
The browser tells me with CURL it should look like this
curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{"cId":"C_ID7","cDomain":"example.com"}' 'http://localhost:3000/api/com.example.Company'
Now I want to send the same message through Java+JSOUP with the following code:
Response resp = Jsoup.connect(baseURL + namespace + "Company").ignoreContentType(true).method(Method.POST)
.ignoreHttpErrors(true)
.requestBody("{\"cId\":\"C_ID7\",\"cDomain\":\"example.com\"}").execute();
The same (without the requestBody and Method.GET) works for GET-requests. ignoreContentType(true) is necessary, because JSOUP will not handle 'application/json', see here. ignoreHttpErrors(true) is necessary, to get through the Http 500 error, which conceals the true error, which I need for trouble-shooting.
So then finally what I see, when I execute the above code, is the following error:
{"error":{"statusCode":500,"name":"Error","message":"Property names containing dot(s) are not supported. Model: com_example_Company, dynamic property: {\"cId\":\"C_ID7\",\"cDomain\":\"example.com\"}","stack":"Error: Property names containing dot(s) are not supported. Model: com_example_Company, dynamic property: {\"cId\":\"C_ID7\",\"cDomain\":\"example.com\"}\n at com_example_Company.ModelBaseClass._initProperties

where obviously [user] is my username. So I had a look at the loopback-datasource-juggler sources and found that in model-builder.js (source on Github) instead of parsing the different properties of the string, it is given the complete string ("{\"cId\":\"C_ID7\",\"cDomain\":\"example.com\"). In line 269 the builder checks whether there are dot-characters in the property-name. Since in our case the property name is the complete JSON-string, there are dots and the program fails.
Unfortunately XML does not seem to be supported at this point.
Now: How can this happen? My only guess is an encoding thing done by Java, because the same JSON works in the browser. Any ideas what could have caused this?
And one smaller issue: The error message in the code is ''Property names containing dot(s) are not supported. ' + 'Model: %s, property: %s'', but in the error I receive it says something about "dynamic property". Am I at the wrong point for searching what causes the error?

Since you have already specified 'Content-Type: application/json', you needn't have double quotes in the requestBody. The following should work:
Response resp = Jsoup.connect(baseURL + namespace + "Company").ignoreContentType(true).method(Method.POST)
.ignoreHttpErrors(true)
.requestBody({\"cId\":\"C_ID7\",\"cDomain\":\"example.com\"}).execute();

the curl example is what the REST APIs (rather than merely the browser) know about the business network REST API endpoints.
for your requestBody, you will need the fully qualified class (ie meaning asset/participant/transaction class with leading namespace) - an example is :
curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{ \
"$class": "org.example.biznet.SampleAsset", \
"assetId": "1", \
"value": "103300" \
}' 'http://localhost:3000/api/SampleAsset'
So yours will be something like
Response resp = Jsoup.connect(baseURL + namespace + "Company").ignoreContentType(true).method(Method.POST)
.ignoreHttpErrors(true)
.requestBody("{\"\$class\": \"org.example.biznet.SampleAsset\", \"cId\":\"C_ID7\", \"cDomain\":\"example.com\"}").execute();
I believe you also needed at least one other double-quotes (total above now : 14) and a closing curly bracket in addition.
