示例1:
const invocationCallback = (errorValue, successValue) => {
connection.end(JSON.stringify({
result: successValue,
errorMessage: errorValue && (errorValue.message || errorValue),
errorDetails: errorValue && (errorValue.stack || null)
}));
};
示例2: Error
const invocationCallback = (errorValue, successValue) => {
if (hasInvokedCallback) {
throw new Error('Cannot supply more than one result. The callback has already been invoked,'
+ ' or the result stream has already been accessed');
}
hasInvokedCallback = true;
connection.end(JSON.stringify({
result: successValue,
errorMessage: errorValue && (errorValue.message || errorValue),
errorDetails: errorValue && (errorValue.stack || null)
}));
};
示例3: dynamicRequire
readline.createInterface(connection, null).on('line', line => {
try {
// Get a reference to the function to invoke
const invocation = JSON.parse(line) as RpcInvocation;
const invokedModule = dynamicRequire(path.resolve(process.cwd(), invocation.moduleName));
const invokedFunction = invocation.exportedFunctionName ? invokedModule[invocation.exportedFunctionName] : invokedModule;
// Prepare a callback for accepting non-streamed JSON responses
let hasInvokedCallback = false;
const invocationCallback = (errorValue, successValue) => {
if (hasInvokedCallback) {
throw new Error('Cannot supply more than one result. The callback has already been invoked,'
+ ' or the result stream has already been accessed');
}
hasInvokedCallback = true;
connection.end(JSON.stringify({
result: successValue,
errorMessage: errorValue && (errorValue.message || errorValue),
errorDetails: errorValue && (errorValue.stack || null)
}));
};
// Also support streamed binary responses
Object.defineProperty(invocationCallback, 'stream', {
enumerable: true,
get: (): Duplex => {
hasInvokedCallback = true;
return connection;
}
});
// Actually invoke it, passing through any supplied args
invokedFunction.apply(null, [invocationCallback].concat(invocation.args));
} catch (ex) {
connection.end(JSON.stringify({
errorMessage: ex.message,
errorDetails: ex.stack
}));
}
});
示例4: dynamicRequire
readline.createInterface(connection, null).on('line', line => {
try {
// Get a reference to the function to invoke
const invocation = JSON.parse(line) as RpcInvocation;
const invokedModule = dynamicRequire(path.resolve(process.cwd(), invocation.moduleName));
const invokedFunction = invocation.exportedFunctionName ? invokedModule[invocation.exportedFunctionName] : invokedModule;
// Actually invoke it, passing the callback followed by any supplied args
const invocationCallback = (errorValue, successValue) => {
connection.end(JSON.stringify({
result: successValue,
errorMessage: errorValue && (errorValue.message || errorValue),
errorDetails: errorValue && (errorValue.stack || null)
}));
};
invokedFunction.apply(null, [invocationCallback].concat(invocation.args));
} catch (ex) {
