njpatel / grpcc Goto Github PK

Tried running against a .proto file without a package declaration and grpcc couldn't locate any services inside.

While executing the basic gprcc command on Mac OS Sierra:
grpcc --proto <file> --address 127.0.0.1:<port>

I'm getting the following errors

TypeError: Cannot read property 'ns' of null
    at Object.load (/usr/local/lib/node_modules/grpcc/node_modules/grpc/src/node/index.js:152:28)

    at Module.runMain (module.js:604:10)
    at run (bootstrap_node.js:394:7)

Update:
This only happens when the 'file' path is absolute.

When using a relative path, like the following command, I get an other error. This seems because of an import statement of an other proto file in the referenced file. The import statement is relative by itself, but it uses the base-path from where you run the gprcc-command, instead of the base-path of the file where the import statement occurs

The import statement in the supplied proto-file is

import "../google/protobuf/timestamp.proto";

The simple work-around is to navigate to the directory where the proto-file is, and executing:
grpcc --proto ./chaincode.proto --address 127.0.0.1:7051

I guess it is possible to fix?

Tried to install. Said it needed node-pre-gyp. Installed it and it still didn't work

Hi,

I;m getting the following error message while starting grpcc :

> xx@dvlp2:~$ grpcc
> /usr/bin/env: ‘node --harmony’: No such file or directory
> xx@dvlp2:~$ node -v
> v6.9.1

Thank you.

Cheers,
jj

I've got a protobuf file with a single service. When running with v1.1.0 I get the expected behaviour, but with v1.1.1 there seems to have been a regression, as I get an Unable to find any service in proto file error message when running grpcc -p ./my-proto-file.proto -a 127.0.0.1:3456.

At first glance, maybe this line needs to be updated to have the second argument?

If enum is outside a message (top-level), grpcc picks up on the enum and considers it a package name, rendering the tool unusable.

e.g.

package grpcctest;

enum EventType {
  TEST = 0;
  TEST_AGAIN = 1;
}

What package you want to use? (Use arrow keys)
❯ grpcctest.EventType.TEST
  grpcctest.EventType.TEST_AGAIN

Expected:

What package you want to use? (Use arrow keys)
❯ grpcctest

I tried and failed to find how to perform gRPC call in non-interactive mode. Is it possible?

Btw, interactive mode is gorgeous! Thanks 👍

This is for cases where the GRPC server only accepts certificate signed by a defined CA.

When using dot-delimited packages (as is usual in the java world) e.g. "com.foo.package", grpcc only offers the first path component as an option:

grpcc --proto My.proto --directory path/to/proto/ --address localhost:8091 -i
? What package you want to use? com

Hi,

There is a display bug with the oneof fields. Even if one of the values is set, it always displays null.

Example :

message Message1 {
    string name = 1;
    oneof example {
        Type1 value1 = 8;
        Type2 value2 = 9;
    }
}

Output :

{
  "name": "Dexter",
  "example": null
}

My project's proto has tons of import, packages without any rpc service . This helps a lot.

Can be easily change in https://github.com/njpatel/grpcc/blob/master/lib/index.js#L23
From:

let packages = Object.keys(JSON.parse(JSON.stringify(parsed)));

To

let packages = Object.keys(parsed).filter((pkn) => Object.keys(parsed[pkn]).some((spkn) => parsed[pkn][spkn].name === 'ServiceClient'))

https://github.com/njpatel/grpcc/blob/master/lib/index.js#L27

    inquirer.prompt([{
      type: 'list',
      name: 'packageName',
      message: 'What package you want to use?',
      choices: packages
    }])

I've tried completely deleting everything associated with node and I can not get grpcc to install through rpm at all.

Cool tool! I can definitely see this being handy for testing some of my endpoints!

I'm getting this error; and unfortunately don't have the context to debug it myself,

    repeated string must_contain = 3;

A basic "hello world" grpc worked fine, any ideas why this doesn't work?

My grpc server responds correctly to my java client so I'm confident the server is working.

Hello,

The way we use grpc we require more than one .proto file. Would it be interesting to be able to use more than one proto file?

Hey,

Just had a confusing moment with the tool. Basically, the tool seems to fail when loading packages from deeper path levels than the first one. Something like package example; works and the tool correctly finds the definitions. If I have something like package com.example.v1;, the tool will not find the definitions and exits silently with no error message.

The error happens choices: Object.keys(parsed) as it is currently not traversing the hierarchy stored in let parsed = grpc.load(file); but instead just lists the top level packages

For test auth protected apis in server side, could request header customization feature be added? Or, do we already have this function? Didn't see docs about this feature.

this is not how you use eval?

The protobuf "well-known types" (https://developers.google.com/protocol-buffers/docs/reference/google.protobuf) are included in every language runtime, including the npm package (see protocolbuffers/protobuf#1638).

Currently, grpcc requires proto files that import a well-known type to have a copy of the well-known type locally, otherwise you get an Error: failed to import '...' in './foo.proto': file not found error.

These well-known types should be handled automatically by importing them from the protobuf npm package instead.

I am new to gRPC but using this tool how do you provide a client id and secret with the endpoint address?

Whenever I add an import to the proto file, grpcc can't find any service.
e.g. import "google/protobuf/field_mask.proto";

I haven't tested or debugged it any further but my guess is that it only checks the imported proto definition as it doesn't have any services in it.

I've added an enum at the root of the package of a proto file and the grpc options for packages shows as follows:

https://puu.sh/xyr8B/806119c65a.png

If you wrap the enum in a message, it resolves the problem and shows the proper package for the API.

https://puu.sh/xyr9N/3c5858b4df.png

Please support the following example proto file to ensure that you can find a package even with enum at the root

`
package kintohub.authblock.generated;

service AuthBlock {
rpc Login(LoginRequest) returns (LoginResponse) {
option (google.api.http) = {
post: "/auth/login"
body: "*"
};
}

rpc Register(CreateRequest) returns (CreateResponse) {
	option (google.api.http) = {
		post: "/auth/register"
		body: "*"
	};
}

rpc ValidateEmail(ValidateEmailRequest) returns (ValidateEmailResponse) {
	option (google.api.http).get = "/auth/validate";
}

//	rpc ForgotPassword(ForgotPasswordRequest) returns (ForgotPasswordResponse) {
//		option (google.api.http) = {
//			post: "/auth/forgotpassword"
//			body: "*"
//		};

Firstly thanks for putting this tool out.

I am having issues sending GRPC requests where the input is a message with more than one fields. Can you please provide examples for such cases ares.

MyCli@unix:/tmp/my_socket> client.createRequest({name: "Hello", input: 2, output: 4}, printReply)
EventEmitter {}
MyCli@unix:/tmp/my_socket> Error: { [Error] code: 12, metadata: Metadata { _internal_repr: {} } }

I tried other json style combinations and I keep getting more basic errors, hence the request..

Thanks!!

Send non-proto rpc

For using gRPC with protocols other than protobuf, you will need the exact method name string and a file containing the raw bytes to be sent on the wire.

$ grpc_cli call localhost:50051 /helloworld.Greeter/SayHello \
  --input_binary_file=input.bin \
  --output_binary_file=output.bin
On success, you will need to read or decode the response from the output.bin file.

https://github.com/grpc/grpc/blob/master/doc/command_line_tool.md

Your tool can't do this, right?

Unfortunately env in Linux doesn't support arguments, so executing grpcc fails immediately. Omitting

See discussion in SpencerCDixon/redux-cli#42 on possible solutions. grpcc seems to work well with the stable Node even without the --harmony flag.

I wish to provide the "default authority" ChannelOption when connecting to the service. Right now there does not seem to be a possibility to do this.

I need to pass a proto map via grpcc. My .proto file is like this:

message AttemptFriendshipRequest {
  //other params
    map<string, string> params = 2;
}

How should the json input body be?

I tried following but didn't work:

{.... , params: {"lastName":"demoUserLName"}}

{.... , params:[ {"lastName":"demoUserLName"}]}

Please provide a streaming example through command line interactive mode. Something like the following:
var call=client.getSomething({id_list=["1","2","3"]});call.on('data', function(feature){console.log(feature)});

On Windows.. If we try to use google's timestamp.proto, we have to copy the google directory from the contents of C:\Users\USER_NAME.nuget\packages\google.protobuf.tools\3.2.0\tools\ into the C:\Path\To\Proto directory containing MyFile.proto
That .proto file has an import like so:
import "google/protobuf/timestamp.proto";

That's a problem b/c although there's a workaround to copy the google directory over we have to tell git to ignore it so it isn't checked in, and protobuf.tools may be updated at a later date, meaning manually updating that directory, just for testing with grpcc.

Here is the command line I tried (and many similar variants):

C:\Path\To\Proto>grpcc --proto ./MyFile.proto --address 127.0.0.1:12345 -i -d "C:\Users\USER_NAME.nuget\packages\google.protobuf.tools\3.2.0\tools"

As mentioned, simply copying "google" over to C:\Path\To\Proto worked fine.

I have a problem with empty error:
I call:

 client.getAllMetadata({}, pr)

and I recevied empty error:

 Error:  { Error
    at C:\user\AppData\Roaming\npm\node_modules\grpcc\node_modules\grpc\src\node\src\client.js:554:15 code: 12, metadata: Metadata { _internal_repr: {} } }

Is the error from gRPC endpoint or grpcc tool? Thank you.

This issue is the flip side of #33; when I receive metadata, I expect something like:
{"x-request-id": "1234", "x-error-id": "0xdeadbeef"}, but I get { 'x-error-id': [Array], 'x-request-id': [Array] } as the _internal_repr.

(This is using .on('metadata', pr).)

Above on ubuntu 14.04 and node 0.10.25

I tried it on OSX with node 0.10.18 and got the same thing.

Often times, .proto files will depend on .proto file that aren't in the same directory (they may be on a system include path or pulled in as part of a dependency).

Would it be possible to have a command line option that specifies a search path for included .protos (similar to protoc)?

‏@louiscryan: @njpatel @grpcio Very cool! You might want to take a look at https://t.co/vQLFqrcxBs and support that at some point

I'm getting this error when connecting to a grpc service.

Versions:

I tried to run grpcc using simple .proto file :

But after hitting Enter the error message mentioned in the title appeared :

Even using the .proto file mentioned in grpcc example yielded the same error for me.

What can possibly be the cause and how to fix it? Anybody else, probably in a different environment (OS, version of npm and node), experiencing this error?

I can reproduce the error on Windows 10, using the following version of node & npm :

λ node -v
v6.10.2
λ npm -v
3.10.10

as well as on Ubuntu 16.10, using higher version of node & npm :

$ node -v
v7.9.0
$ npm -v
4.2.0

$ npm install -g grpcc
/usr/local/bin/grpcc -> /usr/local/lib/node_modules/grpcc/bin/grpcc.js

I'm wondering how I can add metadata? I'm trying to add an authentication method to my gRPC service and testing with grpcc will be useful. So hopefully there's a way?

This is a Feature Request than a bug or issue

I found this https://www.npmjs.com/package/protobuf-jsonschema which can provide json schema of proto messages,

It would be great if we can embed it into the CLI, so that we can know how to construct the Request Response objects and may be validate them before actually making the API call.
