arcgis for js 前端GP服务调用

1.先发布好GP服务,例子可参考：https://www.cnblogs.com/hjyjack9563-bk/p/16077788.html，发布好服务后可以看到浏览器如下类似的GP服务

 

2.前端要创建的

Geoprocessor对象

FeatureSet对象作为graphic的集合

注意：传参的参数名要跟服务里的参数名相对应

 

 

 完整代码

//GP创建
var gp = new Geoprocessor(url)
      var featureset = new FeatureSet()
      // featureset.features = [graphic]
      featureset.features = me.initlyr.graphics.items
      var featureset1 = new FeatureSet()
      featureset1.features = me.rltfw
      var para = {
        'KQZL': featureset,
        'Z_值字段': 'PJZ',
        '掩膜范围': featureset1,
        '表达式': "Year = 2019 AND Month = 1 AND TYPE = 'PM2.5'",
        '重分类区间值': ''
        // 'cflvals': '0 50 1;50 100 2;100 150 3;150 200 4;200 300 5;300 500 6'
      }

//GP调用
gp.submitJob(para).then(jobinfo => {
        console.log('gg', jobinfo)
        // 'output'----对应着服务的参数名
        gp.getResultData(jobinfo.jobId, 'output').then(res => {
          console.log('ggg', res)
          for (var j in res.value.features) {
            var item = res.value.features[j]
            var poly = {
              type: 'polygon',
              hasZ: false,
              hasM: false,
              rings: item.geometry.rings,
              spatialReference: view.spatialReference
            }
            var tempindex = Number(item.attributes['gridcode'])
            // var tempindex = Number(item.attributes['grid_code']) - 1
            var fillsym = {
              type: 'simple-fill', // autocasts as new SimpleFillSymbol()
              color: me.tempColor[tempindex],
              outline: {
                // autocasts as new SimpleLineSymbol()
                color: [255, 255, 0],
                width: 0
              }
            }
            var attr = item.attributes
            attr.type = 'rlt'
            var gra = new Graphic({
              geometry: poly,
              symbol: fillsym,
              attributes: attr
            })
            me.rltlyr.add(gra)
          }
          view.map.reorder(view.map.findLayerById('界线'))
          me.loading = false
        })
      })
