+
+### url [String]
+
+http request url
+
+### api_token [String]
+
+Orbit API Token, you can get more detail at this link:
+
+https://api.orbit.love/reference/authorization
+
+### method [String]
+
+http request method, only supports GET, POST method
+
+### params [Map]
+
+http params
+
+### body [String]
+
+http body
+
+### poll_interval_ms [int]
+
+request http api interval(millis) in stream mode
+
+### retry [int]
+
+The max retry times if request http return to `IOException`
+
+### retry_backoff_multiplier_ms [int]
+
+The retry-backoff times(millis) multiplier if request http failed
+
+### retry_backoff_max_ms [int]
+
+The maximum retry-backoff times(millis) if request http failed
+
+### format [String]
+
+the format of upstream data, now only support `json` `text`, default `json`.
+
+when you assign format is `json`, you should also assign schema option, for example:
+
+upstream data is the following:
+
+```json
+{
+  "code": 200,
+  "data": "get success",
+  "success": true
+}
+```
+
+you should assign schema as the following:
+
+```hocon
+
+schema {
+    fields {
+        code = int
+        data = string
+        success = boolean
+    }
+}
+
+```
+
+connector will generate data as the following:
+
+| code | data        | success |
+|------|-------------|---------|
+| 200  | get success | true    |
+
+when you assign format is `text`, connector will do nothing for upstream data, for example:
+
+upstream data is the following:
+
+```json
+{
+  "code": 200,
+  "data": "get success",
+  "success": true
+}
+```
+
+connector will generate data as the following:
+
+| content |
+|---------|
+| {"code":  200, "data":  "get success", "success":  true}        |
+
+### schema [Config]
+
+#### fields [Config]
+
+the schema fields of upstream data
+
+### content_json [String]
+
+This parameter can get some json data.If you only need the data in the 'book' section, configure `content_field = "$.store.book.*"`.
+
+If your return data looks something like this.
+
+```json
+{
+  "store": {
+    "book": [
+      {
+        "category": "reference",
+        "author": "Nigel Rees",
+        "title": "Sayings of the Century",
+        "price": 8.95
+      },
+      {
+        "category": "fiction",
+        "author": "Evelyn Waugh",
+        "title": "Sword of Honour",
+        "price": 12.99
+      }
+    ],
+    "bicycle": {
+      "color": "red",
+      "price": 19.95
+    }
+  },
+  "expensive": 10
+}
+```
+You can configure `content_field = "$.store.book.*"` and the result returned looks like this:
+
+```json
+[
+  {
+    "category": "reference",
+    "author": "Nigel Rees",
+    "title": "Sayings of the Century",
+    "price": 8.95
+  },
+  {
+    "category": "fiction",
+    "author": "Evelyn Waugh",
+    "title": "Sword of Honour",
+    "price": 12.99
+  }
+]
+```
+Then you can get the desired result with a simpler schema,like
+
+```hocon
+Http {
+  url = "http://mockserver:1080/contentjson/mock"
+  method = "GET"
+  format = "json"
+  content_field = "$.store.book.*"
+  schema = {
+    fields {
+      category = string
+      author = string
+      title = string
+      price = string
+    }
+  }
+}
+```
+
+Here is an example:

+- Test data can be found at this link [mockserver-contentjson-config.json](../../../../seatunnel-e2e/seatunnel-connector-v2-e2e/connector-http-e2e/src/test/resources/mockserver-contentjson-config.json)
+- See this link for task configuration [http_contentjson_to_assert.conf](../../../../seatunnel-e2e/seatunnel-connector-v2-e2e/connector-http-e2e/src/test/resources/http_contentjson_to_assert.conf).
+
+### json_field [Config]
+
+This parameter helps you configure the schema,so this parameter must be used with schema.
+
+If your data looks something like this:
+
+```json
+{
+  "store": {
+    "book": [
+      {
+        "category": "reference",
+        "author": "Nigel Rees",
+        "title": "Sayings of the Century",
+        "price": 8.95
+      },
+      {
+        "category": "fiction",
+        "author": "Evelyn Waugh",
+        "title": "Sword of Honour",
+        "price": 12.99
+      }
+    ],
+    "bicycle": {
+      "color": "red",
+      "price": 19.95
+    }
+  },
+  "expensive": 10
+}
+```
+
+You can get the contents of 'book' by configuring the task as follows:
+
+```hocon
+source {
+  Http {
+    url = "http://mockserver:1080/jsonpath/mock"
+    method = "GET"
+    format = "json"
+    json_field = {
+      category = "$.store.book[*].category"
+      author = "$.store.book[*].author"
+      title = "$.store.book[*].title"
+      price = "$.store.book[*].price"
+    }
+    schema = {
+      fields {
+        category = string
+        author = string
+        title = string
+        price = string
+      }
+    }
+  }
+}
+```
