无法执行 Google Cloud Functions Android 客户端调用。
我从云控制台创建 Cloud Function,并在云控制台上进行测试。
但在 Android 客户端应用程序上,它不起作用。
所以,我确实在我的 android studio 上导入了谷歌云服务快速启动项目,同样的错误。
这是快速启动项目的 url。
https://cloud.google.com/functions/docs/quickstart-console
这是我的代码。
谷歌云函数调用类
public class TestClass {
private FirebaseFunctions mFunctions;
public TestClass(){
mFunctions=new FirebaseFunctions();
}
..
public Task<String> myFunc(String text) {
// Create the arguments to the callable function, which is just one string
Map<String, Object> data = new HashMap<>();
data.put("message", text);
return mFunctions
.getHttpsCallable("myFunc")
.call(data)
.continueWith(new Continuation<HttpsCallableResult, String>() {
@Override
public String then(@NonNull Task<HttpsCallableResult> task) throws Exception {
// This continuation runs on either success or failure, but if the task
// has failed then getResult() will throw an Exception which will be
// propagated down.
String result = (String) task.getResult().getData();
Log.d("gcf",result);
return result;
}
});
}
在MainActivity的执行方法中
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
TestClass testClass=new TestClass();
testClass.myFunc("im bhw")
.addOnCompleteListener(new OnCompleteListener<String>() {
@Override
public void onComplete(@NonNull Task<String> task) {
if (!task.isSuccessful()) {
Exception e = task.getException();
if (e instanceof FirebaseFunctionsException) {
FirebaseFunctionsException ffe = (FirebaseFunctionsException) e;
FirebaseFunctionsException.Code code = ffe.getCode();
Object details = ffe.getDetails();
}
// [START_EXCLUDE]
Log.w("gcf", "myFunc:onFailure", e);
Toast.makeText(getApplicationContext(),"An error occurred.",Toast.LENGTH_SHORT).show();
return;
// [END_EXCLUDE]
}
// [START_EXCLUDE]
String result = task.getResult();
Toast.makeText(getApplicationContext(),result,Toast.LENGTH_SHORT).show();
// [END_EXCLUDE]
}
});
}
});
谷歌云函数
exports.myFunc = (req, res) => {
if (req.body.message === undefined) {
res.status(400).send('No message defined!');
}
else {
console.log(req.body.message);
res.status(200).send('Success: ' + req.body.message);
}
};
exports.myFunc = (req, res) => {
if (req.body.message === undefined) {
res.status(400).send('No message defined!');
}
else {
console.log(req.body.message);
res.status(200).send('Success: ' + req.body.message);
}
};
结果

最佳答案
响应至少必须包含一个具有数据 或错误 值的 JSON 对象。
如果您将函数修改为:
exports.myFunc = (req, res) => {
if (req.body.message === undefined) {
res.status(400).send({error: 'No message defined!'});
}
else {
console.log(req.body.message);
res.status(200).send({data: 'Success: ' + req.body.message});
}
};
exports.myFunc = (req, res) => {
if (req.body.message === undefined) {
res.status(400).send({error: 'No message defined!'});
}
else {
console.log(req.body.message);
res.status(200).send({data: req.body.message});
}
};
你应该没问题。
