怎么给某个合约地址授权？

我是这么写的，但是点击按钮，没有反应:

// before all, request privilege, first
  const handleReqPri = () => {
    const w = new Web3(ether);
    const wethAdr = getWETHContract(w);
    const strBlindAuctionAdr = getBlindAuctionAddress();
    wethAdr.methods
      .approve(strBlindAuctionAdr, new BigNumber("100000000000000000"))
      .call()
      .then(function (result: any) {
        console.log("handleReqPri ===>", result);
      })
      .catch((_error: any) => {
        // If the request fails, the Promise will reject with an error.
        console.error("privilege error ? : ", _error);
      });
  };
