Angular HttpClient issue when calling Bing Maps Locations REST methods



I have an existing call to Bing Maps made with Angular 4 Http service, that is working correctly:


this.http.get(".../Locations?...&key=mykey")



I'm trying to change the call to use the HttpClient service introduced in Angular 4.3, but when trying the same code:


this.httpClient.get(".../Locations?...&key=mykey")



then the request is sent with the preflight OPTIONS request, and bing maps obviously refuses it.



I've tried to observe the request instead of the body, requesting a text response, and force the Accept header to text, but had no success.



Headers of the Http request (working):


Accept: application/json, text/plain, */*
Origin: http://localhost:4200
Referer: http://localhost:4200/
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36



Headers of the HttpClient request (not working):


Access-Control-Request-Headers: authorization
Access-Control-Request-Method: GET
Origin: http://localhost:4200
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36



Any idea about why the HttpClient request is so different than the Http request?how do I force the HttpClient to skip the preflight OPTIONS request? Am I missing something?



Thanks in advance for any help





Are your URLs relative or absolute? because I only see ".../Locations ..., not knowing what the first three dots stand for! And by the way, do you have an CORS plugin or something similar activated?

Clash Royale CLAN TAG #URR8PPP Arduino Mega cannot recieve any sketches, stk500_recv() programmer is not responding Yesterday we were trying to update the firmware of our 3D-printer a Tevo Tarantula i3 The printer was running Marlin 3D Printer Firmware. We installed a new module a TL-Touch Sensor, a chinese copy of the Bl-Touch an auto bedleveling touch sensor for a 3D printer. After re-configurating a new version of the firmware for our setup in the Arduino IDE we went on with uploading the sketch to the Arduino Mega that was controling our 3D printer. Before we started uploading we made sure the right COM-port was selected in the Arduino IDE and that also the right type of Arduino was selected. The Arduino Mega 2260. Then we started with compiling the firmware and then uploading it to the Mega, Somewhere in between that moment the IDE freezed and crashed. As a response we removed the USB cable that was connected from the PC uploading the firmware onto the Arduino Mega, (This was a st...

Clash Royale CLAN TAG #URR8PPP C++ virtual function: Base class function is called instead of derived I have following code snippet: using namespace std; class base { public: virtual void print(char a){ std::cout<<" Base "<<std::endl;} }; class derived :public base { public: void print(floata) {std::cout<<" Derived "<<std::endl;} }; int main() { base* d = new derived; d->print(1.5); return 0; } Output is "base" Why output is coming from base function and not from derived one By clicking "Post Your Answer", you acknowledge that you have read our updated terms of service, privacy policy and cookie policy, and that your continued use of the website is subject to these policies.
